Out West, a girl has her capacity (3)
I believe the answer is:
gal
'capacity' is the definition.
The definition and answer can be both quantities as well as being singular nouns.
Maybe there's a link between them I don't understand?
'out west a girl has her' is the wordplay.
I cannot really understand how this works, but
'a' is found in the answer.
'girl' could be 'g' and 'g' is found in the answer.
A single letter 'l' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for gal that I've seen before include "miss" , "Lass" , "measure of acceleration?" , "Broad" , "An American girl, cowboy vintage" .)
