"Oh! My fiancée is so cute!" shouted the woman.
Now, if you know correct English and you read this sentence, you will think that the woman is a lesbian. There's no possible explanation for having a fiancée, who is a betrothed woman.
The word for an engaged man is fiancé, without that 'e' at the end. So the first sentence should be, "Oh! My fiancé is so cute!"
Fiancé: Betrothed man
Fiancée: Betrothed woman
Both these words are pronounced, 'fee on say'. The plural forms are simply 'fiancés' and 'fiancées'.
Don't forget the acute diacritic sign above the letter, 'e'.
These words originate from the French verb, 'fiancer', which means 'to become engaged'. So, you see, both these words originate from the French language, in which they are still strongly in use.
