Definitions for "Iago"
the villain in William Shakespeare's tragedy who tricked Othello into murdering his wife
Iago is a fictional character in William Shakespeare's play Othello.
Iago (voiced by Gilbert Gottfried) is a fictional character in the 1992 Disney animated film Aladdin, a talking parrot resembling a Scarlet macaw who served as a sidekick for Jafar. Iago later switched sides in The Return of Jafar, in which his struggle against his power-hungry nature was a large part of the plot; he remained good in both the movie and the TV series, but he was still largely conniving, greedy, and cowardly. He is most likely named after the villain Iago in the play Othello, by William Shakespeare.
Iago is a genus of houndshark in the family Triakidae.
