Bare Romeo amongst writhing bodies (7)
I believe the answer is:
disrobe
'bare' is the definition.
(thesaurus)
'romeo amongst writhing bodies' is the wordplay.
'romeo' becomes 'r' (phonetic alphabet: alpha, bravo, charlie etc.).
'amongst' is an insertion indicator (I've seen this in other clues).
'writhing' is an anagram indicator.
'bodies' anagrammed gives 'disobe'.
'r' inserted inside 'disobe' is 'DISROBE'.
(Other definitions for disrobe that I've seen before include "Undress" , "bare" , "Get undressed" , "Remove formal clothing" , "Strip" .)
