Funny huts are like this (4)
I believe the answer is:
thus
'like this' is the definition.
(I've seen this before)
'funny huts' is the wordplay.
'funny' indicates anagramming the letters.
'huts' with letters rearranged gives 'THUS'.
'are' acts as a link.
(Other definitions for thus that I've seen before include "Like so" , "an original Christmas gift" , "In this way" , "As a result" , "In this manner" .)
