Married man eats lunch noisily? (5)
I believe the answer is:
champ
'lunch noisily?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'married man eats' is the wordplay.
I cannot quite see how this works, but
'married' could be 'm' and 'm' is located in the answer.
'man' could be 'chap' (I've seen this in other clues) and 'chap' is present in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for champ that I've seen before include "Bite - victor (abbr)" , "Supreme competitor" , "Title holder (abbr)" , "Munch loudly - the winner!" , "Munch noisily; winner" .)
