3.1 Permanent epenthesis

The typical OE form of the adjective empty was æmtig(e). This form accounts for 87 out of 91 tokens for the word in DOEC. The remaining four occurrences are with epenthetic p. These form are attested in Ælfric's texts: Saint Euphrosyne (emptige), homily Feria VI (æmptig) and the second letter to Wulfstan (æmptige), as well as in Psalms from MS Cotton Vitellius E.XVIII (æmptig). Thus, the written evidence suggests that the epenthesis can be dated to the end of the Old English period. Interestingly, none of the related words, i.e. the verb (ge)æmtigian and the noun æmta, betrays any tendency towards the addition of a stop.

In Early Middle English, forms with epenthetic p are still in the minority, as shown in data from LAEME, which contains six such forms as compared to ten without the stop. But they gain frequency in the period so that the ratio of the two types of forms is reversed in the CMEPV, where empty (also spelt with initial <a>) is encountered 68 times while emti/amti occurs merely 23 times. Interestingly, the forms with and without the stop are occasionally found within the same texts (1a) or in different manuscripts of one source (1b).

1. (1)

   1. (a) and þe slak[e] skyn trembleþ vpon myn emty body … wiþ a lijfly colour and wiþ swiche vigoure and strenkeþ þat it ne myȝt[e] not be emptid. (Chaucer, Boece, British Library, MS Additional 10340, pp. 4–5)

   2. (b) Þat were ampty In þine londe ⋅ ware þou wost bi þenche ⋅*. [were ampty] amty were B; ampti were α; ampty were βγ. …] (Robert of Gloucester, Chronicle, l. 944)

In Early Modern English (EModE), forms without p become very rare: there are only 67 occurrences in EEBO (vs more than 40,000 instances of the p-form). In the OED the most recent quotation with emty is that from Brevint's Saul and Samuel at Endor, dated to 1674, but EEBO provides later uses, such as in Allestree's Clito and Harrington's The Oceana, both published in 1700. With no examples found in ECCO, these two seem to be the last attestations of the p-less form in English.

Curiously, the data also contain forms in which the dental t is missing rather than the labial p, as in (2).

1. (2)

   1. (a) … yt is to say yt he be not to full ne to empy to full then wolde the humours louse … (1506?, Here begynneth a lytell treatyse called the gouernall, unnumbered)

   2. (b) … Oh man, thou art a vessel, but a ful vessell, put out & empy that which is within thee … (1618, La Primaudaye, The French academie …, p. 881)

With only two such examples, however, it is impossible to determine whether such a form ever reflected the pronunciation or was simply the result of a misprint.

In empty, the context for epenthesis is: between the labial nasal and the dental stop. However, as noticed by Ohala (Reference Ohala1997: 84–5), the context of nasal + fricative could also lead to the development of epenthetic stops (cf. e.g. the pronunciation of warmth or the name Thomson). Such a context is encountered in glimpse. As its first attestation, the OED provides the line from Chaucer's The Merchant's Tale, which contains the form glimsing (with the variants glemesyng and glynsyng (MED)). The OED suggests that the verb could go back to an unattested OE item *glimsian (from West Germanic *glimmisôjan). The first verbal form with p is recorded by the OED in 1592 with an earlier record of the noun glimpsing, dated to 1563. This instance is also the earliest one in the examined data and one of the two attestations of the word in the CMEPV. The word gains frequency in Early Modern English, when the form with p becomes around 15 times more common than that without the stop (158 vs 2,391 occurrences in EEBO, respectively). Rare as it is, glimse continues to appear until the end of the seventeenth century, the last attestation coming from 1699 in EEBO (the last record in the OED is from 1663).

The data that I considered also contain several other items which are recorded in historical texts both with and without p, which might suggest that they, too, were affected by epenthesis. To those belong words such as e.g. peremptory and tempt(ation). Such words, however, are disregarded in the present study since they already had p when they entered the language, as the first attestations, given here in (3), show.

1. (3)

   1. (a) … have from þe King lettres peremptorie of request to þe said Duc such as þe cas requireth. (Proceedings and Ordinances of Privy Council 1443 (1835) V. 277)

   2. (b) … þet te deouel tempti us ouer þet he sið wel þet we mahen þolien. I þe temptatiun he haueð iset to þe feond a mearke. (Ancrene Riwle, MS Corpus Christi College 402, c.1230(?a.1200), p. 118, ll. 9–10)

The fact that the labial stop in these words may not be original can be deduced only on examining their etymology. Peremptory comes from an Anglo-Norman word which had the variants with and without the stop, i.e. peremptorie/paremptorie as well as peremtorie/perantorie (OED, peremptory), while tempt was borrowed from French (tempter) coming from Latin temptāre/temtāre (OED, tempt). Thus, it is possible that the words that entered English derived from the variants containing the stop, which would mean that no epenthesis took place during the history of English.

Note that, similarly to empty, the two types of forms are also occasionally attested within the same text for peremptory (4a) and temptation (4b), showing that they could be used interchangeably.

1. (4)

   1. (a) And when this choice after Deliberation is peremtory and full, it's called Resolution … And your Resolution must be Absolute and peremptory,… (Baxter, Directions and perswasions to a sound conversion …, 1658, pp. 449–56)

   2. (b) … þat þou be myn help & counfort in al my temtacioun, … ȝit, lord swete Ihesu, þis liff is ful of temptaciouns and enemyes, … (Rolle, Meditations on the Passion, University Library MS Additional 3042, pp. 93–4)

Epenthetic p is also encountered in several English place names, i.e. particularly those with the compound element -hamton, which in OE functioned separately as ‘a common local name’ (ASD) or together with another item, e.g. Northampton. The consonant is also found with other place-name types ending in -ton. To identify such items, the Old English corpus was searched for place names containing an mt cluster, which emerged due to the addition of the above-mentioned elements. This resulted in eight items: Hampton(shire), Northampton(shire), Southampton(shire), Wolverhampton, Bempton, Brampton, Compton and Rimpton. Additionally, place names with an ms cluster were identified, the search yielding a further eight items: Berkhamsted, Cockampstead, Dunhampstead, Elmhamstede,Footnote ⁵ Finchampstead, Hampstead, Peorhamstede and Stanhamstede. Although place names obviously do not provide as reliable evidence as common words, they are briefly discussed here for two reasons: first, to expand the data for p-epenthesis, which is quite scant in comparison to that illustrating the addition of b, and, second, to see whether the analysis of the process of p-epenthesis in place names would lead to the same observations as those for common items. Hence, I searched for the listed names in the corpora to identify their forms. I supplemented the data collected with the information from two dictionaries of place names, namely Ekwall's Concise Oxford Dictionary of English Place-Names (ODEPN) and Watts's Cambridge Dictionary of English Place-Names (CDEPN).

According to the data, the first place names affected by labial epenthesis were (chronologically) Compton, Wolverhampton, Brampton, Bempton, Hampton, Hampshire and Southampton(shire), all of which have appearances with p, albeit usually a single case, before the end of the twelfth century. Of those, the earliest attestation of the p-variant seems to be that of Comptone in Surrey recorded in 675 in Cartularium Saxonicum (ODEPN, CDEPN). The next to develop p in written variants were Hampstead, Northampton and Finchampstead, which are found with the stop before the fifteenth century. Rimpton is not listed with p in the dictionaries but the form occurs in the mid-seventeenth century in EEBO. As regards other items, they either have no entry in the dictionaries (Elmhamstede, Peorhamstead, Stanhampstead) or they always appear there (and in other data) without the stop (Cockhampstead, Dunhampstead Footnote ⁶). Interestingly, one item seems to be an exception since it has never been recorded with p, namely Berkhamsted. For the majority of names, both variants coexisted in the language, often for many centuries, as was the case with e.g. Hampton(shire) and Southampton(shire), whose p-less variants are attested even in the eighteenth century.

The data concerning place names thus suggest that items containing an mt cluster were more prone to epenthesis than those with ms. This is shown by the fact that names with mt are recorded with p earlier and the data contain no exceptions to epenthesis, whereas among those with ms there is Berkhamsted, which resisted epenthesis, and Medeshamstede, which had it only occasionally (see section 3.2 below).

3.2 Occasional and temporary epenthesis

As mentioned above, the forms which reveal epenthetic p only occasionally and are now attested without it include æmette (PDE ant), antemn (PDE anthem), comte (PDE count, verb and nouns), column, dreamt, hymn, nemnan (PDE name), somnour (PDE summoner) and the place name Medeshamstede. Table 2 shows their first and last attestations with p.

Table 2. First and last occurrences of items with epenthetic p in the data

In table 2, the items affected are arranged according to their first attestation with epenthetic p. Note that the list of words discussed disregards items which were also affected by epenthesis but did not survive to Present-day English, such as e.g. amtman ‘bailif’, recorded also as amptman, or demster, with a variant dempster, an item obsolete in English and used only in Scots (DSL). As can be seen, the majority of words appeared with the voiceless labial stop in the Middle English period, although antemn shows epenthesis already in Old English (e.g. in Benedict's Rule), while Medeshamstede only shows it in the seventeenth century (The Church-History of Brittany, 1668). The p-forms typically disappear in Early Modern English (sixteenth–seventeenth centuries) with two words, nemnen and count, displaying variation till the second half of the eighteenth and the second half of the nineteenth century, respectively. According to the OED, the word summoner still appeared with p in the twentieth century, although only in historical contexts. This makes the word an item recorded with and without p for the longest time, i.e. around six centuries.

In the words listed in table 2, epenthesis is observed in three contexts. Apart from the above-mentioned clusters mt (æmette, comte, dreamt) and ms (Medeshamstede), the insertion of p is also observed between nasals mn (antemn, column, hymn, nemnan and somnour), a context which is not observed in the case of permanent p-epenthesis in English. The items with an mt cluster include two native words (æmette, dreamt) and one borrowing from French (comte). The earliest p-form recorded belongs to the past tense of dremen ‘to dream’. The verb, unattested in Old English, is first recorded in Middle English, when it has two types of past forms, i.e. those with -ed (dremed) and those with -t (dreamt). In the latter, the attachment of the suffix results in the labial nasal plus dental stop cluster, allowing the development of epenthetic p, resulting in dreampt(e). The data show that, in Middle English, whenever the past tense is created via the attachment of t, the epenthetic stop is always present. The form dreamt without p is secondary, appearing only at the beginning of the seventeenth century. Although the OED gives 1628 as its first attestation, the data reveal earlier examples, as in (5).

1. (5)

   1. (a) … I dremt his bow was broke, and he was slaine… (1606, Bartlet, A booke of ayres, song VI)

   2. (b) … I neuer dremt of any thing lesse thē building churches, … (1606, Peacham, The art of dravving vvith the pen …, unnumbered)

Similarly, the date of the last usage of dreampte should be extended from 1653 (OED) to 1676, when the variant is used in News from the sessions house in the Old-Bayly London, which is included in EEBO.

The second word, ant, is affected by epenthesis in the second half of the fourteenth century, when the variant amptis is used in Wyclif's Bible, and continues in English till the second half of the sixteenth century. Around that time, the new variant ant, with the dental, rather than labial, nasal appears, which does not meet the context for epenthesis. Note, however, that the sequence ampt survives today in the place name Ampthill.

In contrast to the previous two cases, count is a borrowing from French, ultimately coming from Latin comptum, hence, its spelling ‘was refashioned in 14th cent., after Latin, as compte’ (OED, count). And indeed, the fourteenth century witnesses the appearance of p in verbal forms (e.g. compteth, compten in Gower's Confessio Amantis) and nominal forms (e.g. compte in Chaucer's Romance of the Rose). The p-variant of this word is very persistentFootnote ⁷ since compte is recorded even in the nineteenth century and that form is much more frequent than the one with an mt cluster, which is typically used as a title (comte) and an element of place names (e.g. Franche-comte). As in the case of ant, the variant with epenthesis is replaced by the one with nt.

The sequence ms was identified in only one word with non-permanent epenthesis, i.e. the place name Medeshamsted. In both Old and Middle English, the name is written only as the variant without p. The labial stop appears in Early Modern English, but it is very rare as EEBO records only three such uses as compared to 159 instances of Medeshamstead. This, however, is not that surprising since it is a historical name and as such it is preserved in its old form, often with the explanation that this place is ‘now (called) Peterborough’.

The last group of words are those with an mn cluster, identified in five items. The first of them to appear with p is antemn ‘anthem’, which comes from Latin antefana and in Old English was typically used in the form antefn. Already in that period, however, its variant antemn emerged, with the cluster mn, which created a context for the epenthetic labial stop p (OED, antemn). The form antempn(e) is used till the mid-sixteenth century: the last quotation from the OED comes from 1530, but EEBO includes one instance from Rastell's A confutation of a sermon printed in 1564.

The next item with the mn sequence with p is hymn, an OE borrowing of Latin hymnus, mostly attested in the form (h)ymen, which means that in inflection there must have been a cluster mn. Still, the first recorded use with p, shown in (6), does not belong to Old but rather Early Middle English (?c.1225 (?a.1200)).

1. (6) For swa is inhis ympne. (Ancrene Riwle, British Library, MS Cotton Cleopatra C.vi, l. 124)

Interestingly, the DOEC reveals the form ympnus; it is not present in an OE text but in the Latin title of a psalm, Te decet ympnus deus in Syon, included in the Winteney Version of Benedict's Rule. This is a later version of the rule so it cannot be treated as an Old English text, but the citation shows that epenthesis affected the word also in medieval Latin.Footnote ⁸ According to the OED, the labial stop is found in hymn till 1513, but my data reveal more than 150 uses in EEBO so it did not disappear in the Middle English period. The last attestation in the data is from 1569, the year of publication of Diodorus's A righte noble and pleasant history …, which contains the form hympnes. Sources dated to later years also contain the variant but only while quoting older texts.

The OE form nemnan ‘to name’ developed into ME nemnen. First attested in Ancrene Riwle (c.1230 (?a.1200)), the variant nempne becomes more frequent than nemne, outnumbering it both in the CMEPV (146 instances to 104) and EEBO (61 instances to 1), and is present in the language until at least 1782. Its decline is best demonstrated by the data from ECCO, which contains only three instances of nempne, all in Warton's The History of English Poetry in quotes from Lives of Saints ‘written after the year 1169’ (Warton Reference Warton1774–81: 14), thus a historical text. The p-less form nemne is not found there at all, showing that name was already functioning as the main variant.

The last two items, summoner and column, are both borrowings. The former comes from French and was first recorded in English in c.1300. The word is found in Southern Passion preserved in MS Harley 2277, in the form somenours, which, curiously, appears as sompnours in MS Pepys 2344 from a.1325. Thus, the two variants are attested in English almost at the same time. They both continue to be used till modern times, with the forms sompner/sompour still found, albeit very rarely, in twentieth-century texts. The final item, column, entered English from Latin (columna/columpna) via French (colompne/colombe) around 1440. The OED has only one attestation of the form with p, given here in (7), which suggests that it might have been a unique usage.

1. (7) In thyse grete colompnes or pylers..were grauen the vii scyences. (1481, Caxton's trans. Myrrour of Worlde iii. xi. 158)

However, as the data from the CMEPV and MED show, the form with p was, in fact, predominant in Middle English. The corpus contains three tokens and the MED lists five quotations, with no instances of a p-less variant in either. Soon, the situation changes radically as shown by the data from EEBO with more than a thousand tokens without p vs 24 of colompne/columpne, the most recent coming from 1577.

In none of these words did labial stop epenthesis become permanent. In the two items with an mt cluster (ant and count), m was replaced by n thus creating a homorganic cluster nt. In count, the replacement seems to have been quite natural, since for both words, i.e. the one denoting the title and that referring to calculation, the variants with nt already existed in French before the words entered English (e.g. AF/CF conte(r)). Ant arose in the fifteenth century. Interestingly, the word also survived with the labial nasal as emmet, where the problematic cluster was avoided due to the preservation of the vowel. The words with an mn cluster typically dropped the second nasal from the pronunciation (anthem, column, hymn), although in the case of nemnan one may speak of the elimination of the lexeme, since, according to both the MED and OED, nemnan developed from OE (ge)nemnan while name derives from (ge)namian. Although cognates from a common source and with very similar sense, the latter eventually ousted the former. Summoner, like emmet, has a vowel separating the two sounds in question. This leaves only two words in Present-day English which still meet the context for epenthesis: Medeshamstead and dreamt. The former has quite rare attestations since it is only used in historical contexts. The latter is still quite often encountered, although its frequency is considerably lower than that of the regularized variant dreamed: in British English the ratio of the two forms is 27% : 73% (British National Corpus (BNC)), in American the variant dreamt is marginal with the ratio 11% : 89% (Corpus of Contemporary American English (COCA)).

4.1 Permanent epenthesis

Four words, fimble, rumble, stumble and tumble, display b from their first attestation in English. The epenthesis here is observed only on comparing cognates from other languages and/or variants without the stop encountered in English.

Chronologically, the earliest of the four items is tumble, first attested in English in 1303 in the form tumbled, as in (8).

1. (8) Eroud swore / To here þat tumbled yn þe flore (Mannyng, Handling Sin, British Library, MS Harley 1701, ll. 2819–20)

The fact that b is not original is shown by cognates such as German tummeln, Frisian tommelje, or Danish tumle (OED). Interestingly, this form gave rise to the verb tumbian ‘to tumble, to dance’ (ASD) albeit used very rarely (two attestations plus three of the related noun tumbere ‘a tumbler, a player’), in the Old English period. The verb re-emerges in the fourteenth century and its sense undergoes modification, presumably under the influence of the French verb tumber/tomber ‘to fall’. According to the dictionaries, the first record without the stop is from Barbour's Bruce 1487 (a.1380), which contains the forms tumlilt and tummyll. The b-less variant appears for the last time in The flytting betwixt Montgomerie and Polwart from 1629 but, as the data from the corpora show (10 tokens in EEBO), its frequency was never high.

The pattern is repeated in the case of stumble and rumble. Both emerged in English with the epenthetic stop in the fourteenth century, as shown in (9), the former in 1303, the latter in c.1405 (c.1375).

1. (9)

   1. (a) Ful many on stumble vp and down (Mannyng, Handling Sin, British Library, MS Harley 1701, l. 6521)

   2. (b) The peple cride and rombled vp and doun (Chaucer, The Monk's Tale, National Library of Wales, MS Peniarth 392D (Hengwrt), l. 449)

Later, both verbs are recorded without b, e.g. stomleþ in Trevisa's translation of Bartholomaeus (a.1398) and rummuelon in Promptorium parvulorum (1440). Although the OED provides only two citations for the b-less forms of stumble, a verbal form from Torrent of Portyngale (a.1500 (a.?1400)) and an adjectival form from The Castle of Perseverance (c.1425), the data contain six more examples (plus one noun), the most recent coming from Fovrteen sermons dated to 1697. Note, however, that the stop is never missing from the noun stumble. As regards rumble, the variant without b is very rare in the data, with merely six examples from EEBO (plus single uses of a noun), but, according to the OED, it is still present in the language in Scottish English (also in Scots) and in northern Irish English in the sense ‘to agitate, to shake’.

The last item in the group, fimble, is a borrowing from French (femelle ‘female hemp’Footnote ⁹) but is also an obsolete variant of fumble and famble. Yet, as noted in the OED, it is attested without the stop only as the former, since the quotation from ?1507 provided by the dictionary is the only recorded b-less form.

The extant literature lists one more item, which displays the emergent stop from its first record in English, namely timbrian ‘to build’. However, in the case of this verb the fact that b is not etymological is proved only by its reconstructed form *tim-r- and cognates such as Dutch timmeren or Danish tömmre. Labial stop epenthesis is visible not only in English but also in some other Germanic languages, e.g. Old Saxon timbrian, Old High German zimberen, or Old Norse timbra (OED). Thus, since it is impossible to verify whether epenthesis took place in English or at an earlier stage, the item is not included in the analysis. In any case, in English, the word it is always attested with the stop.

The remaining 13 items, listed in table 3, underwent b-epenthesis some time after their first attestation in English.

Table 3. First occurrences of surviving words with epenthetic b

In contrast to table 1, presenting the results of Wełna's analysis, table 3 disregards the above-mentioned items which display epenthesis from their first attestation in English. On the other hand, the list is augmented with three recent words subject to epenthesis, i.e. famble, numb and fumble. As can be seen, epenthesis affected some words quite quickly, e.g. bramble and thumb appear with b already at the end of the Old English period; while fumble is recorded with the stop about 20 years after its first attestation in English. In the case of other words, the process was much slower, the best example here being limb which, although used already in Old English, is first recorded with b only at the end of the sixteenth century.

The analysis of my corpus material has led me to revise some of the dates for the first attestations suggested by Wełna on the basis of the dictionaries. In the OED, the first usage of ember with b is dated to Promptorium parvulorum from c.1440, but the form ember is found in Lanfrank's Science of cirurgie included in the CMEPV, dated to a.1400, given here in (10).

1. (10) … bynde yt in a clothe & put yt under embers, … (Lanfrank's Science of cirurgie, Bodleian Library, MS Ashmole 1396, p.190)

This example, however, is not completely reliable since it does not come from the body of the text but is encountered in a marginal note. As explained by the editor: ‘The translator has omitted the prescription of oleum tartarinum, given in the Lat. original. It is written by a later hand on the margin of lf. 114, bk.’ Thus, it is impossible to suggest its exact dating.

For nimble, the earliest occurrence the OED provides is the 1496 version of Treat. Fishing, whereas nemble is encountered in The Romance of Sir Beues of Hamtoun, the original of which is dated to the beginning of the fourteenth century, given here in (11).

1. (11) Syr Beuys was bothe nemble and wyght (The Romance of Sir Beues of Hamtoun, Chetham's Library MS 8009, l. 2252)

But yet again, this dating is quite vague since the form is in the version preserved in Chetham's Library MS 8009, assigned to a.1500, thus it is unclear whether it belonged to the original text or was changed later and, if so, when exactly. The form numb is first recorded in 1610 (OED) but EEBO contains e.g. Huloets dictionarie newelye corrected from 1572, i.e. around forty years earlier, which includes the phrase ‘Members being ded or numbe’. Additionally, the dating of the form limb, which Wełna assigns to the latter half of the sixteenth century, can be specified as 1595, in the edition of Caxton's Blanchardyn and Eglantine, shown here in (12), from the CMEPV.

1. (12) … who not only had bemangled his limbes, but alſo bereft him of his looue and Miſtreſſe, … (Caxton's Blanchardyn and Eglantine, p. 22)

In the case of almost all items, the two types of forms, i.e. those without and those with epenthetic b, coexisted for some time in the language. As the timeline in figure 1 shows, the period of such coexistence may range from merely a few years to several centuries.

Figure 1. The occurrences of words with epenthetic b (solid line) and without (dotted line)

The longest coexistence of forms with and without b is recorded for thumb, which first shows evidence of epenthesis in 1137 but the variant without the stop was in use until the end of the seventeenth century. Thus, the two types of forms were present in the language for around 500 years. The second longest time span belongs to bramble (around 415 years), followed by crumb (around 380 years). On the other hand, the data from the dictionaries and the corpora suggest that famble and fumble appeared with epenthetic b only some time after the forms without the stop became obsolete, suggesting that they never coexisted as written variants.

The material examined here also enables post-datings for the last recorded uses of b-less forms provided by OED. For shamble, the last record can be extended from 1574 (10th Rep. Royal Comm. Hist. Manuscripts) to 1593 (Fruitfull lessons, …), that for nimble from 1568 (Satirical Poems Reformation) to 1607 (Lingua: or The combat of the tongue …). Yet the biggest revisions in dating are for ember and slumber, which are attested in the corpora respectively 50 and 100 years later than the dates given by the OED: the dictionary quotes the last attestation of a b-less form of ember from a.1522 (Douglas's transl. of Æneid), but this type of variant is found in a text from 1579 (13a), while slumber, last recorded in the OED in 1599 (Hume's Hymnes) is attested in 1699 (13b).

1. (13)

   1. (a) … and couer it in the hoat Emers of smale coales and ashes. (Bulleins bulwarke of defence …, p. 3)

   2. (b) She adds, she's troubled a nights with broken Slumrs (The characters, or, The manners of the age by Monsieur de la Bruyere …, p. 259)

Note also, that some b-less variants (e.g. of shamble, nimble or numb) are encountered in particular dialects long after they became obsolete in standard English.

The words affected by b-epenthesis have different frequencies, thus the search for some of them in the corpora gives scant results. To these belong especially the words that appeared in the language or were affected by epenthesis most recently, such as fimble, fumble and numb, for which little or no comparative data can be found in the medieval English corpora. Also thimble and, quite surprisingly, ember, have only a few attestations in the corpora of texts earlier than Early Modern English (EEBO). In the case of such words, it is difficult to trace the changing ratio of forms without and with b. As regards other items, the data show that for bramble, thumb and slumber, the forms with b outnumber those without the stop already in the CMEPV, the ratio being 15:1, 112:13 and 52:32, respectively. For the remaining words i.e. crumb, mumble, nimble and shamble, b-variants are still a minority in Middle English and become more frequent than the ones without b only in EEBO.

As the examples show, b-epenthesis is encountered in three contexts: (1) between m and l (bramble, famble, fimble, fumble, mumble, nimble, rumble, shamble, stumble, thimble, tumble), between m and r (ember, slumber) and word-finally after m (crumb, limb, numb, thumb). All these contexts have been discussed in linguistic literature (see section 2). Obviously, in some items, the context was met only when the word was inflected, since the form often contained an intervening vowel, e.g. OE brǽmel (PDE bramble), numel (PDE nimble), þýmel (PDE thimble), scomul (PDE shamble), and/or emerged when the vowel was lost. It is noteworthy that the words are typically much more frequently encountered in the forms demanding the vowel than in the ones without it, e.g. for brǽmel in the DOEC, there are 31 tokens of the form with the vowel (as yielded by a search for the string brǽm(b)el*) vs 17 without it (from a search for the string brǽm(b)l*). And, curiously, in the case of bramle the emergent stop appears more often when m and l are separated by the vowel (3 tokens of brembel/brember) than when the cluster is present (2 tokens: brembrum and bremblas). Also other items (numel, þýmel, scomul) are never attested in the corpus in the inflected forms containing an ml cluster. Thus, it seems that the elimination of an unstressed vowel was much more effective for epenthesis than the context created by inflection. As regards words with final epenthetic b, the addition of the stop is due to analogy to words with final mb, especially when b was no longer pronounced, which led to the appearance of hypercorrective forms with b. In this case, it was undoubtedly only the letter that was added and not the sound.

4.2 Occasional and temporary epenthesis

As mentioned earlier, most words which showed an occasional or temporary variant with epenthetic b did not survive in the language, e.g. OE aþum ‘son-in-law’, cumul ‘swelling’, or simle ‘a service, continual’. Thus, English has only one item that underwent such epenthesis for a period and survived until the present day, i.e. hemlock (OE hymlic). The first record of that noun with a labial stop is from the Old English period in Latin–Old English Glossaries, which contain the form huymblicae (glossing Latin cicuta). This is also the only b-variant of the word in the period. Similarly, the Middle English corpora examined contain only one instance of that word, the form humbloks found in Mandeville's Travels. The noun gains frequency in later texts, as shown by around 1,200 attestations in EEBO, 28 of which have b. The last record of the b-form is dated to 1729 (OED).

In hemlock, the context for epenthesis is between m and l. Thus, the environment for the occasional b-epenthesis is not different at the consonantal level from that for the permanent one. The word hemlock has a full vowel following, however, while items showing permanent epenthesis typically have a reduced one, although this difference is observed in one word only, other items (aþum, cumul, simle) not showing such a context.
