Did I guess incorrectly? It's intentionally misleading (9)
I believe the answer is:
disguised
'intentionally misleading' is the definition.
(something disguised is meant to mislead)
'did i guess incorrectly?' is the wordplay.
'incorrectly?' indicates anagramming the letters (I've seen this in other clues).
'did'+'i'+'guess'='didiguess'
'didiguess' is an anagram of 'DISGUISED'.
'it's' is the link.
(Other definitions for disguised that I've seen before include "Masquerading" , "Incognito" , "Camouflaged, masked" .)
