Out West, she has a grand fellow (3)
I believe the answer is:
gal
'out west she' is the definition.
The definition suggests a singular noun which matches the answer.
'a grand fellow' is the wordplay.
'a grand' becomes 'g' (G is short for grand as in a thousand).
'fellow' becomes 'al' (I've seen this in other clues).
'g'+'al'='GAL'
'has' acts as a link.
Can you help me to learn more?
(Other definitions for gal that I've seen before include "US female" , "miss" , "An American girl, cowboy vintage" , "Young woman (colloq.)" , "Lady" .)
