Siren
noun /ˈsaɪrən/ — Something irresistibly beautiful that leads you toward danger.
Definition
In Greek mythology, a creature whose enchanting music lured sailors onto rocks; anything irresistibly alluring but potentially dangerous; a device that emits a warning sound.
Beyond the definition
The sirens sang to Odysseus and his crew — music so beautiful that sailors steered toward it without being able to stop themselves. The metaphor now describes anything whose beauty contains a trap: a person whose charm draws you in before you notice the cost, an idea that sounds perfect but destroys on arrival.
Origin & history
From Greek Seirēn — mythological creatures who lured sailors to their deaths with beautiful singing. Often depicted as half-woman, half-bird.
