Passionate at home, teens excited (7)
I believe the answer is:
intense
'passionate' is the definition.
(I've seen this before)
'at home teens excited' is the wordplay.
'at' is a charade indicator (letters next to each other).
'home' becomes 'in' (to be in is to be (at) home).
'excited' indicates an anagram.
'teens' with letters rearranged gives 'tense'.
'in' next to 'tense' is 'INTENSE'.
(Other definitions for intense that I've seen before include "Forceful, concentrated" , "Strong in degree or emotion" , "Very marked" , "Extremely earnest or serious" , "Acute difficulty" .)
