Hot tea he'd spilt (6)
I believe the answer is:
heated
'hot' is the definition.
(synonyms)
'tea he'd spilt' is the wordplay.
'spilt' is an anagram indicator.
'tea'+'hed'='teahed'
'teahed' is an anagram of 'HEATED'.
(Other definitions for heated that I've seen before include "Angry, impassioned" , "Angry - passionate" , "Raised the temperature" , "Angry or warmed" , "Fired-up" .)
