Eat best, in short? (5)
I believe the answer is:
champ
This could be a double definition.
'eat' is the first definition.
The definition and answer can be both related to consumption as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'best in short?' is the second definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
Can you help me to learn more?
(Other definitions for champ that I've seen before include "Bite - victor (abbr)" , "Munch (at the bit?)" , "Victor (slang)" , "Chew noisily" , "Title holder (abbr)" .)
