Great stylish present for one (7)
I believe the answer is:
intense
'great' is the definition.
(thesaurus)
'stylish present for one' is the wordplay.
'stylish' becomes 'in'.
'present for one' becomes 'tense' (present is a kind of tense**).
'in'+'tense'='INTENSE'
(Other definitions for intense that I've seen before include "Extremely emotional" , "'Ardent, forceful (7)'" , "Strong in degree or emotion" , "Forceful, concentrated" , "Fierce - deep" .)
