I'd assume whatever the female version of "knight" is, but I don't think knight is a masculine noun to begin with; pretty sure it's gender neutral.

Aah ok. I was confused because when I looked it up I got this as a response:

Because there is no female equivalent to a Knight Bachelor, women are always appointed to an order of chivalry. Women who are appointed to the Most Noble Order of the Garter or the Most Ancient and Most Noble Order of the Thistle are not given the title of "Dame" but "Lady".

So I figured if women can't be appointed as a Knight then is it ok to call a woman a knight in shining armour? Or does gender not matter with idioms/phrases? I mean we have "damsel in distress" but what would the male equivalent be since a guy can't be a damsel? So confused.

You can say "knightess" but it's preTTy obsoleTe.

A cheap ***** that will put out for the night. Most men don't long for that idealistic fairytale woman.

A damsel in distress

Oh, I totally missed your question

Gender influences idioms less-and-less as society progresses. You can call a woman a "knight in shining armor" and it would be perfectly acceptable (as long as you left out that hideous "u)."

I can't leave the "u" out because I'm British
