Origin of immortal

1325–75; Middle English (adj.) < Latin immortālis. See im- 2, mortal

Explanation

Immortal describes what will never die. Do you like vampires? Those blood-suckers are immortal, and will live forever — except, of course, if you drive a stake through their heart. The word immortal can refer a supernatural being who is worshipped by others, or is a divinity or God in human form, like the gods of Greek and Roman mythology. Immortal can also mean "a person whose fame lasts for many years." If you're a sports legend or a well-known author, you may be remembered as an immortal in your field. Immortal comes from the Old French word immortalité, meaning "deathlessness."
