So I would like the book to have the quote "I will not be broken" in irish.

I have this translation: Ní ghéillfidh mé choice

Is this correct or is there a better way to say it?

Ní ghéillfidh mé is a good translation, it means literally "I will not surrender/give up".

You could perhaps take a more literal route with [b]Ní bhrisfear mé[/], that can definitely work too.

Wait for more input.

thank you for the quick reply.

Which do you think works better if I mean to say a person's will wont be broken?

I agree that both can work, but note that it's choíche.

I was wondering what "choice" was meant to be :P

Ní ghéillfidh mé choíche

I will never surrender/give up
