Spirit in angel angelic! (4)
I believe the answer is:
elan
'spirit' is the definition.
(elan is a kind of spirit)
'in angel angelic' is the wordplay.
'in' says the answer is hidden in the clue.
'ELAN' is hidden in the letters of 'angel angelic'.
(Other definitions for elan that I've seen before include "Stylishness" , "Bounce" , "Impressive and energetic style" , "Flair and dash" , "Dash, style" .)
