Rotund wild bees are too well fed (5)
I believe the answer is:
obese
'well fed' is the definition.
(thesaurus)
'rotund wild bees are too' is the wordplay.
I cannot quite see how this works, but
an anagram of 'bees' is 'bese' which is located in the answer.
A single letter 'o' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for obese that I've seen before include "More than podgy" , "Dangerously corpulent" , "Unhealthily large" , "Unhealthily fat and overweight" , "Plump" .)
