Quite happy about, in Europe? (9)
I believe the answer is:
continent
'europe?' is the definition.
(Europe is a continent)
'quite happy about in' is the wordplay.
'quite happy' becomes 'content'.
'about' is an insertion indicator.
'content' enclosing 'in' is 'CONTINENT'.
(Other definitions for continent that I've seen before include "chaste" , "huge area of land" , "Africa, say" , "Africa, for example" , "Monk vows" .)
