Archaic Latin, also termed Old Latin, is the name given to the stage of Latin represented in the earliest known inscriptions down to the middle of the second century BCE. Common authors towards the end of this period include Livius Andronicus, Plautus, and Terence. Differences between this stage of Latin and Classical Latin cut across spelling, verbs, and nouns. This chapter will focus on differences from the last two, though differences in spelling will be noticed in examples illustrating the other two categories. This chapter is by no means exhaustive but provides only a few points to illustrate the differences between Archaic and Classical Latin. As is the usual practice in the study of inscriptions, forms which occur only in inscriptions are capitalized.
