Temperate land mass (9)
I believe the answer is:
continent
This clue is a double definition.
'temperate' is the first definition.
(thesaurus)
'land mass' is the second definition.
(I know that continent is a type of land mass)
(Other definitions for continent that I've seen before include "Great landmass" , "Sober" , "chaste" , "Europe, for one" , "dry?" .)
