Cool present for one getting passionate (7)
I believe the answer is:
intense
'passionate' is the definition.
(I've seen this before)
'cool present for one getting' is the wordplay.
'cool' becomes 'in' ('in' can mean fashionable or cool).
'present for one' becomes 'tense' (present tense).
'getting' is a charade indicator (letters next to each other).
'in'+'tense'='INTENSE'
(Other definitions for intense that I've seen before include "Strongly felt" , "Extremely emotional" , "Feverish" , "Fervent" , "'Acute, extreme (7)'" .)
