Shakespearean sprite (5)
I believe the answer is:
ariel
'shakespearean sprite' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ariel that I've seen before include "Shakespearian spirit" , "29 9 [TEMPEST CHARACTER]" , "Heavenly body" , "Moulding round top of wall" , "Enchanting islander" .)
