Origin

late Middle English: from Old French definitif, -ive, from Latin definitivus, from definit- 'set within limits', from the verb definire (see define).

Usage

Definitive is often used, rather imprecisely, when definite is actually intended, to mean simply ‘clearly decided’. Although definitive and definite have a clear overlap in meaning, definitive has the additional sense of ‘having an authoritative basis’. Thus, a definitive decision is one which is not only conclusive but also carries the stamp of authority or is a benchmark for the future, while a definite decision is simply one which has been made clearly and is without doubt.
