mae

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

This clue might be a double definition.

'western' is the first definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?

'girl?' is the second definition.

Can you help me to learn more?

(Other definitions for mae that I've seen before include "The first Hollywood blonde femme fatale, . . . West" , "- West, US film actress" , "- - West, life-jacket" , "- - West, movie vamp" , "Girl" .)

I've seen this clue in the Evening Standard.
