How to say "fiance" in Japanese

• フィアンセCommon
  nounCovers either sense — the person you are engaged to, whether fiance or fiancee, as Japanese does not mark gender. A loanword with a slightly elegant flavor, fitting when you introduce or describe that person.
  白しろい洋服ようふくを着きている子こが私のフィアンセだ。↗

  The girl who is dressed in white is my fiancée.
• 婚約者こんやくしゃCommon
  nounAlso means the person you are engaged to, whether a fiance or a fiancee. Built from 婚約 (engagement) and 者 (person), it is plain and descriptive, fitting neutral, matter-of-fact statements about an engagement.
  ケイトは婚約者こんやくしゃからもらった大おおきなダイヤモンドの指輪ゆびわをいつもみせびらかしている。↗

  Kate always shows off the big diamond ring she got from her fiance.

Both words mean the person you are engaged to marry, with no distinction between fiance and fiancee; choose 「フィアンセ」 for the French loanword's slightly elegant flavor, or 婚約者 for the neutral, plainly descriptive term.
