A seabird with white and gray feathers that lives near water; or as a verb, to trick or deceive someone easily.
From Breton 'gouel' or Old Norse 'gulls,' meaning gull. The meaning 'to deceive' came later because gulls were seen as foolish birds that could be easily fooled.
Gulls were considered so stupid in old folklore that calling someone a 'gull' meant they were gullible—which is why we say 'gullible' today, originally meaning 'stupid like a gull.'
