Team up just in golf? On the contrary (5)
I believe the answer is:
merge
'team up' is the definition.
(thesaurus)
'just in golf? on the contrary' is the wordplay.
I cannot really understand how this works, but
'golf?' could be 'g' (phonetic alphabet: alpha, bravo, charlie etc.) and 'g' is found within the answer.
'just' could be 'mere' (I've seen this before) and 'mere' is present in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for merge that I've seen before include "Combine into one" , "Make one" , "Combine, blend" , "Become one" , "Come together as one" .)
