Male and female for Biblical food (5)
I believe the answer is:
manna
'biblical food' is the definition.
(I've seen this in another clue)
'male and female' is the wordplay.
'male' becomes 'man' (man is a kind of male).
'and' means one lot of letters go next to another.
'female' becomes 'na' (I can't justify this - if you can you should believe this answer much more).
'man'+'na'='MANNA'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for manna that I've seen before include "Spiritual nourishment" , "Heavenly nourishment" , "Sweet gum; an unexpected benefit" , "Godsend" , "Divine food" .)
