Filled with delight (6)
I believe the answer is:
enrapt
'filled with delight' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for enrapt that I've seen before include "Fascinated" , "state of ecstasy" , "Deeply absorbed in something" , "Turned on" , "Spellbound" .)
