Handbooks of Latin usually draw attention to the presence of Greek loanwords from the very earliest stages of the Latin language. Greek loans feature in texts of all types, in a wide range of different spheres: words for flora and fauna, food and drink, aspects of trade, law and administration. The last major study of the Greek loanwords in Latin (Biville ) concentrated on the ways in which Greek sounds were represented in Latin, but did not have so much to say about the place of Greek loanwords within the vocabulary of Latin as a whole. This chapter gives a survey of Greek loanwords in Republican Latin, in both literary and epigraphic documents, with several different research questions in mind. Is it possible to unearth different chronological strata of loanwords? Can learned and vulgar loans be separated in Republican Latin, and how well integrated were Greek loans into Latin? Do phonological and semantic aspects of the words reveal anything about the source of the loans? Why do some Greek loanwords make it into the higher registers of Roman poetry (and sometimes prose) and others not, and how do these conventions come about?
