a play (c. 1603) by William Shakespeare. The story is about a great man who is destroyed by jealousy. Othello is a Moor (= North African) who is a powerful and respected commander (= senior officer) in the navy of Venice. He is gradually persuaded by the evil officer Iago that his wife, Desdemona, and another officer, Cassio, are lovers. Othello kills his wife but then discovers that she was innocent and kills himself.
“O! beware, my lord of jealousy;It is the green-eyed monster which doth mockThe meat it feeds on.”
