Heavenly food for married woman? (5)
I believe the answer is:
manna
'heavenly food' is the definition.
(as in manna from heaven)
'married woman?' is the wordplay.
'married' becomes 'm' (abbreviation, e.g. in genealogy).
'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" , "Food God gave to Moses" , "Miraculous stuff dropped" , "Food provided by God for the Israelites in the wilderness" , "unexpected windfall" .)
