Enthusiastic male interested in culture (6)
I believe the answer is:
hearty
'enthusiastic' is the definition.
(I've seen this before)
'male interested in culture' is the wordplay.
'male' becomes 'he' (he refers to a man).
'interested in culture' becomes 'arty' (I can't explain this - if you can you should believe this answer much more).
'he'+'arty'='HEARTY'
Can you help me to learn more?
(Other definitions for hearty that I've seen before include "Enthusiastic and sincere" , "Enthusastic" , "Vocally cordial in earthy way" , "Having gusto" , "Vigorously healthy" .)
