Frisky, full of fun (7)
I believe the answer is:
playful
I believe this clue is a double definition.
'frisky' is the first definition.
(similar in meaning)
'full of fun' is the second definition.
(I've seen this before)
(Other definitions for playful that I've seen before include "Fun-loving" , "In high spirits" , "Frisky" , "Fond of games; light-hearted" , "Full of fun" .)
