fiancée

This term specifically denotes a woman who has agreed to marry. It carries a formal and romantic connotation, marking a transitional social status between dating and marriage. While the English language has largely moved toward gender-neutral terms, this word remains a precise marker of gender in formal announcements and traditional social contexts.

Because it is borrowed from French, the spelling with a double e is strictly reserved for the female partner. Using this specific spelling when referring to a man is grammatically incorrect in standard English, as the masculine form uses a single e.
