The distribution of loanwords between papyri, inscriptions, and literature is investigated: more appear in literature than in other sources, but papyri have the highest density of Latinisms. Local and regional loanwords existed, and these can be seen not only in papyri and inscriptions, but also in literature, which preserves traces of loanwords specific to the city of Rome. Special attention is paid to the New Testament (especially Acts of the Apostles), Atticising writers (especially Athenaeus and Lucian), the Edict of Diocletian, Roman historians, medical writers (especially Galen), Hesychius, the antiquarian John Lydus, and texts on Roman law (especially Theophilus Antecessor, the Scholia Sinaitica, and Modestinus).

Some Greek texts contain words in Latin script and/or with Latin endings. Latin script occurs mainly in Roman law texts; these are investigated with particular attention to Theophilus Antecessor and the Scholia Sinaitica. Evidence for script mixture within individual words is considered. Words in Latin script and/or with Latin endings are more likely to be codeswitches than loanwords, but some loanwords appear with one or both these features. Multi-word phrases retain their original script and inflections much more often than individual words; these are mostly codeswitches, but some phrases may be loanwords.
