Dividing the Latin language into neat chronological periods will not work without severe reservations. Usages that may seem to be ‘early’ often turn out not to be confined to a particular period, or alternatively their attestations may be genre-related, that is characteristic of a genre that happens to survive mainly from an early period. As for ancient grammarians and commentators on the language, no single concept of what early Latin is may be extracted from their works. Early Latin, or the Latin of ueteres, was a different thing for different commentators. One could use ‘early Latin’ (arbitrarily) of the Latin of the period before about 100 BC, provided that one excludes from the category ‘early’ usages which, though they were current early, also remained current beyond that time. Latin is attested over many centuries, and it was definitely not static. There was not however an entity ‘early Latin’ in use until a convenient date, which then changed into ‘classical Latin’. Recovery of early phenomena requires careful analysis of the distribution, comparative evidence across periods and genres, and a distinction between usage and fashion.
