Take in — hoax (4)
I believe the answer is:
gull
I believe this clue is a double definition.
'take in' is the first definition.
(I know that take in can be written as gull)
'hoax' is the second definition.
(thesaurus)
(Other definitions for gull that I've seen before include "Delude - seabird" , "Cheat, hoax" , "Seabird with webbed feet" , "A bird; to deceive" , "Common seabird" .)
