Clear land (3)
I believe the answer is:
net
This clue is a double definition.
'clear' is the first definition.
('net' can be a synonym of 'clear')
'land' is the second definition.
(thesaurus)
(Other definitions for net that I've seen before include "Trap; open-weave fabric" , "Fish-catcher" , "Meshed trap" , "It's see-through" , "Ultimate" .)
