Usage

What does existential mean? Existential is an adjective meaning “relating to existence,” but what does that even mean? What does anything mean? What is our purpose in the universe? These are existential questions. Existential is often used in relation to existentialism, a philosophical movement that suggests that existence (life, the universe, and everything) has no meaning except for the meaning that individuals create for themselves. Existential is also often used to describe a scenario in which someone or something’s very existence or being is threatened or in question, especially in phrases like existential threat. Example: Though unlikely, an asteroid strike would be an existential threat to the planet.

Etymology

Origin of existential

First recorded in 1685–95, existential is from the Late Latin word existentiālis “relating to existing”; existence, -al 1

Explanation

If something is existential, it has to do with human existence. If you wrestle with big questions involving the meaning of life, you may be having an existential crisis. Existential can also relate to existence in a more concrete way. For instance, the objections of your mother-in-law may pose an existential threat to the continuation of your Friday night card game. Often the word carries at least a nodding reference to the philosophy of existentialism associated with Kierkegaard, Nietzsche, Sartre, and others, which emphasizes the individual as a free agent responsible for his actions.
