Inspired current prince inspired by Kelly? (7)
I believe the answer is:
inhaled
'inspired' is the definition.
(I've seen this in another clue)
'current prince inspired by kelly?' is the wordplay.
'current' becomes 'I' (physics symbol).
'prince' becomes 'hal' (Shakespearean nickname of Henry V when a prince).
'inspired by' is an insertion indicator (some letters breathed in or 'inspired' by others).
'kelly?' becomes 'ned' (outlaw Ned Kelly).
'hal' going inside 'ned' is 'nhaled'.
'i'+'nhaled'='INHALED'
(Other definitions for inhaled that I've seen before include "inspired" , "Breathed in" .)
