It is inspired and lively (8)
I believe the answer is:
spirited
'lively' is the definition.
(similar in meaning)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for spirited that I've seen before include "Full of energy and enthusiasm" , "Energetic, animated" , "Lively, in upbeat mood" , "Mettlesome" , "Sparkling" .)
