Perhaps acutely scraggy? (7)
I believe the answer is:
angular
'scraggy?' is the definition.
(thesaurus)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for angular that I've seen before include "Pointed" , "Bony - lean - gaunt" , "stiff" , "Having sharp corners, lacking curves or smoothness" , "Thin and bony - with sharp corners" .)
