Fashion that is for darling girl? (5)
I believe the answer is:
cutie
'darling girl?' is the definition.
The definition suggests a singular noun which matches the answer.
'fashion that is' is the wordplay.
'fashion' becomes 'cut' (cut is a kind of fashion).
'that is' becomes 'ie' (abbreviation for id est, 'that is' in Latin).
'cut'+'ie'='CUTIE'
'for' is the link.
Can you help me to learn more?
(Other definitions for cutie that I've seen before include "an attractive thing" , "lovely" , "Dish" , "Attractive young woman (slang)" , "Attractive person or animal" .)
