Golf in Africa may be conditionally possible (10)
I believe the answer is:
contingent
'conditionally possible' is the definition.
(possible if certain conditions are met)
'golf in africa may be' is the wordplay.
'golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'in' is an insertion indicator.
'africa may be' becomes 'continent' (Africa is a continent).
'g' inserted inside 'continent' is 'CONTINGENT'.
(Other definitions for contingent that I've seen before include "group of people" , "army unit" , "Quota of troops" , "team" , "not necessary" .)
