Chap in tights torn asunder (7)
I believe the answer is:
danseur
'chap in tights' is the definition.
The definition suggests a singular noun which matches the answer.
'torn asunder' is the wordplay.
'torn' is an anagram indicator.
'asunder' anagrammed gives 'DANSEUR'.
Can you help me to learn more?
(Other definitions for danseur that I've seen before include "One may need to be on one's toes" , "Ballet star" , "Asunder (anag); ballet performer" , "Ballerina's partner" , "Maybe Nureyev" .)
