I'm a little stuck... Click here to teach me more about this clue!

'have they' is the definition.
The definition suggests a plural noun which matches the answer.

(Other definitions for women that I've seen before include "Adult human females" , "Ladies" , "half of our race" .)

I've seen this clue in the Evening Standard.
