Clear, flat land (5)

I believe the answer is:

plain

I believe this is a double definition.

'clear' is the first definition.
(synonyms)

'flat land' is the second definition.
(I've seen this in another clue)

(Other definitions for plain that I've seen before include "Obvious - ordinary" , "lacking special beauty" , "Evident; not fancy" , "ugly" , "Treeless expanse" .)

I've seen this clue in The Irish Independent and The Times.
