Partial to what can be eaten by ants (4)
I believe the answer is:
fond
'partial to' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for fond that I've seen before include "Affectionate, maybe foolish" , "Feeling affection, maybe foolish" , "Partial to" , "Keen on; indulgent" , "Affectionate - tender" .)
