Fat for which wild bees have a love (5)
I believe the answer is:
obese
'fat' is the definition.
(similar in meaning)
'wild bees have a love' is the wordplay.
'wild' indicates anagramming the letters.
'have' is an insertion indicator.
'a love' becomes 'o' (love means zero in tennis).
'bees' anagrammed gives 'bese'.
'bese' going around 'o' is 'OBESE'.
'for which' is the link.
(Other definitions for obese that I've seen before include "indecently large)" , "Extremely fat" , "Extremely overweight" , "Huge" , "getting well-upholstered" .)
