- ity: A noun-forming suffix from Latin -itas, indicating a state or condition.
Etymology Origin:
The word longevity traces back to Latin longaevitas, combining longus (long) and aevum (age). It entered English via Old French longevité, preserving the core idea of "length of life." The morphemes reflect a logical progression: long- (duration) + -ev- (lifespan) + -ity (abstract noun), creating a term for prolonged existence.
