Uncouth diner peeled limb attached to insect (9)
I believe the answer is:
inelegant
'uncouth' is the definition.
(thesaurus)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for inelegant that I've seen before include "Eglantine (anag)" , "laboured" , "Ugly" , "less than couth" , "Ungraceful" .)
