This chapter explores the intersections between work by literary scholars with that done in synchronic and diachronic Latin linguistics. As an example of the different approaches and different toolkits employed by the linguist and the literary scholar, I discuss the way linguists have explained the phrase Veneres Cupidinesque in Catullus 3.1, contrasted with interpretations given in commentaries on Catullus and in Latin dictionaries. In the linguists' account, the phrase is an archaism which continues an earlier Indo-European pattern used to refer to pairs, finding its closest parallels in Sanskrit texts. I then compare literary Latin to other registers and dialects, and discuss the difficulties involved in the term 'Vulgar Latin'. The chapter also examines other areas in which linguistic scholarship might be usefully consulted by readers of Latin literature: word accent, vowel-length and metre; etymology, semantics and the lexicography; grammars and monographs on morphology, syntax and discourse analysis, including in particular recent approaches using sociolinguistics. Passages from Catullus are discussed throughout.
