Old Latin

Old Latin, also known as Early, Archaic or Priscan Latin (Classical Latin: prīsca Latīnitās, lit. 'ancient Latinity'), was the Latin language in the period roughly before 75 BC, i.e. before the age of Classical Latin.^[1] It descends from a common Proto-Italic language; Latino-Faliscan is likely a separate branch from Osco-Umbrian with possible further relation to other Italic languages and to Celtic; e.g. the Italo-Celtic hypothesis.

The use of "old", "early" and "archaic" has been standard in publications of Old Latin writings since at least the 18th century. The definition is not arbitrary, but the terms refer to spelling conventions and word forms not generally found in works written under the Roman Empire. This article presents some of the major differences.
