The chapter sets out to query ancient scholars’ awareness of politeness phenomena as reflected in language and the metalinguistic tools they used to describe them. Particular attention is devoted to the terms charientismos and astimos, as well as to some specific acceptations of reticentia and expressions like grave or durum dictu.

Even if as a general rule ancient grammarians and commentators did not analyse the ordinary spoken language, since they mostly focused on poetry and the more exalted prose genres, it can be argued that all commentators of literary texts pay some considerable attention to ordinary language in interaction, and some attempt is made by them at identifying and labelling what they correctly see as speakers’ rhetorical strategies to reach a pragmatic goal while avoiding conflicts with an interlocutor or giving offence. These writers also make interesting deductions about the social and educational implications of the correct use of politeness etiquette and ritualization.
