To us, the low wet land seems deceptive (5)
I believe the answer is:
bogus
'deceptive' is the definition.
(thesaurus)
'to us' is the wordplay.
'to' becomes 'bog' (I can't explain this - if you can you should believe this answer much more).
'bog'+'us'='BOGUS'
'the low wet land seems' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for bogus that I've seen before include "Spurious" , "Phoney, not genuine" , "Scribbled drawing" , "Not genuine, sham" , "Fake, sham" .)
