Happy to tour in Africa? (9)
I believe the answer is:
continent
'africa?' is the definition.
(africa is a kind of continent)
'happy to tour in' is the wordplay.
'happy' becomes 'content' (associated in meaning).
'to tour' is an insertion indicator (to tour can mean to go around).
'content' placed around 'in' is 'CONTINENT'.
(Other definitions for continent that I've seen before include "Europe, say" , "Europe, for one" , "Temperate - land mass" , "Maybe more than one country" , "Sober" .)
