A treacherous person who lies and manipulates others, named after Shakespeare's villain from 'Othello.'
The character Iago from Shakespeare's 1603 play 'Othello,' who is defined by his duplicitous nature. The name may derive from Spanish 'Santiago' or other sources, but its meaning is now inseparable from the character.
Iago is Shakespeare's greatest villain because he proves that the most dangerous people aren't evil geniuses—they're ordinary people who are great at appearing trustworthy while secretly manipulating everyone, making him uncomfortably realistic.
