Belly engirdling a male shows full range (5)
I believe the answer is:
gamut
'full range' is the definition.
(I've seen this in another clue)
'belly engirdling a male' is the wordplay.
I cannot really see how this works, but
'a' is present in the answer.
'male' could be 'm' (common abbreviation) and 'm' is located in the answer.
'belly' could be 'gut' (informal term for the stomach or gut) and 'gut' is located in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'shows' acts as a link.
Can you help me to learn more?
(Other definitions for gamut that I've seen before include "Complete range or scale" , "Complete range (of something)" , "Entire scale" , "Full extent" , "The whole range or scope of anything" .)
