Shop opening for aggrieved girl (5)
I believe the answer is:
delia
'girl' is the definition.
(I know that Delia is a female given name)
'shop opening for aggrieved' is the wordplay.
'shop' becomes 'deli' (delicatessen).
'opening for' suggests taking the first letters.
The first letter of 'aggrieved' is 'a'.
'deli'+'a'='DELIA'
(Other definitions for delia that I've seen before include "-- Smith, TV cook" , "Sonnets to - (Daniel)" , "Girl" , "Woman" , "-- Smith, TV chef" .)
