Full of life; resonating (7)
I believe the answer is:
vibrant
This clue is a double definition.
'full of life' is the first definition.
(I've seen this in another clue)
'resonating' is the second definition.
(thesaurus)
(Other definitions for vibrant that I've seen before include "Vivacious" , "Brightly-coloured" , "Alive and energetic" , "Lively; pulsating" , "Aquiver with life and excitement" .)
