the.com/fiance

means a man who is engaged to be married.

from From French fiancé, the past participle of fiancer, 'to betroth' — itself rooted in the Latin fidere, 'to trust' (the same faith that underlies words like fidelity and confide). The promise to marry was, quite literally, a pledge of trust. English borrowed the word in the 19th century, accent and all, and never quite let go of the romance — though we did drop the second 'e' for the man and keep it for the woman, fiancée, faithfully echoing French gender endings.
