Home wound up burning (7)
I believe the answer is:
intense
'burning' is the definition.
(I've seen this before)
'home wound up' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'wound up' becomes 'tense' ('tense' can be similar in meaning to 'wound up').
'in'+'tense'='INTENSE'
(Other definitions for intense that I've seen before include "Fierce - deep" , "'Acute, extreme (7)'" , "Of extreme force" , "Deeply emotional" , "Showing strong feelings or opinions" .)
