Excited to take part in advanced gymnastics (4)
I believe the answer is:
edgy
'excited' is the definition.
(thesaurus)
'part in advanced gymnastics' is the wordplay.
'part in' says the answer is hidden in the clue.
'EDGY' is hidden within 'advanced gymnastics'.
'to take' is the link.
(Other definitions for edgy that I've seen before include "Nervous and tense, irritable" , "Uneasy" , "Nervous; jumpy" , "Extremely" , "Keyed up" .)
