Weak feline in food shop, English (8)
I believe the answer is:
delicate
'weak' is the definition.
(associated in meaning)
'feline in food shop english' is the wordplay.
'feline' becomes 'cat' (cat is a kind of feline).
'in' is an insertion indicator.
'food shop' becomes 'deli' (short for delicatessen).
'english' becomes 'E' (abbreviation as in OED).
'deli'+'e'='delie'
'cat' inserted inside 'delie' is 'DELICATE'.
(Other definitions for delicate that I've seen before include "Exquisite; needing tactful handling" , "Very fine in structure" , "Very fine; intricate" , "Very fine; fragile" , "Discriminating" .)
