Enthusiasm for wind, oboe primarily (5)
I believe the answer is:
gusto
'enthusiasm' is the definition.
(I know that gusto is a type of enthusiasm)
'wind oboe primarily' is the wordplay.
'wind' becomes 'gust' (gust of wind).
'primarily' suggests taking the first letters.
The first letter of 'oboe' is 'o'.
'gust'+'o'='GUSTO'
'for' is the link.
(Other definitions for gusto that I've seen before include "Zest, pleasure in action" , "Zest, exuberance" , "Great enthusiasm" , "ardour" , "Got us with great enjoyment" .)
