Fraternises Or Fraternizes.

[Caribeing]

Is either spelling of Fraternizes/Fraternises acceptable in crossword answer.

[Canary42]

Probably

[Lie-in King]

Yes - Chambers gives "...iZe" first. If I were to write the word, however, I'd use "...iSe". That's just me.

I think you should be ok with either.

I would use 'fraternise' as I associate 'fraternize' with American spelling

[Lie-in King]

elliemay - from what I've gleaned over the years, if there's an ambiguous spelling, the checkers are told to accept either.
