Mayo boxer can go about one round (5)
I believe the answer is:
aioli
This might be a double definition.
'mayo boxer' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'go about one round' is the second definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'can' is the link.
Can you help me to learn more?
(Other definitions for aioli that I've seen before include "garlic dip" , "Mayo, in part?" , "Garlic mayo" , "Mayonnaise with garlic" , "Dressing" .)
