Oddly messy, incomplete clue straightened out but somewhat inelegant (6)
I believe the answer is:
clumsy
'inelegant' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for clumsy that I've seen before include "Awkward and unskilful" , "Not dextrous" , "Cack-handed" , "Lacking grace in movement" , "Maladroit" .)
