Food for many a woman (5)
I believe the answer is:
manna
'food' is the definition.
(manna is a kind of food)
'many a woman' is the wordplay.
'many' becomes 'm'.
'a woman' becomes 'anna' ().
'm'+'anna'='MANNA'
'for' acts as a link.
(Other definitions for manna that I've seen before include "Food that God gave the Israelites" , "Heavenly grub?" , "Heavenly food" , "Food God gave to Moses" , "Old Testament food (from heaven?)" .)
