Move restlessly, being unusually gifted (6)
I believe the answer is:
fidget
'move restlessly' is the definition.
(synonyms)
'unusually gifted' is the wordplay.
'unusually' indicates anagramming the letters.
'gifted' is an anagram of 'FIDGET'.
'being' is the link.
(Other definitions for fidget that I've seen before include "appear nervous" , "Move nervously or impatiently" , "Make small restless movements with hands" , "Wriggle" , "Move around nervously" .)
