longevity

Definition

The quality of being long-lasting, especially of life.

Etymology

Early 17th century, learned borrowing from Latin longaevitās, from longaevus (“ancient, aged”) + -itās. The first part is related to English long and this association led to the alternative pronunciation with /ŋ/.
