Public body showing evidence of over-eating (11)
I believe the answer is:
corporation
'public body' is the definition.
'corporation' can be an answer for 'body' (I've seen this before). I am not sure about the 'public' bit.
'showing evidence of over-eating' is the wordplay.
I cannot really understand how this works, but
'showing' could be 'on' (as in a film showing or on at a cinema) and 'on' is found in the answer.
'of' could be 'o' and 'o' is found within the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for corporation that I've seen before include "target of 17, 8 [CHANCELLORS STATEMENT[" , "City body; paunch" , "Large company" , "Big firm" , "belly" .)
