To a male, can suggest porridge (7)
I believe the answer is:
oatmeal
'porridge' is the definition.
(I know that oatmeal is a type of porridge)
'to a male can' is the wordplay.
'can' indicates an anagram (I've seen 'canned' mean this (canned can mean drunk)).
'to'+'a'+'male'='toamale'
'toamale' is an anagram of 'OATMEAL'.
'suggest' acts as a link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for oatmeal that I've seen before include "Kind of porridge" , "ground food!" , "greyish-yellow colour" , "AA Motel (anag.)" , "Basis of porridge" .)
