The definition of gaslit is often treated as a single tidy entry in a dictionary, but it carries social, psychological, and linguistic weight that many people miss.

Short version: gaslit describes when someone is made to doubt their own memory, perception, or sanity through manipulation. Complicated, and widely debated.

What Does definition of gaslit Mean?

The definition of gaslit refers to being subjected to gaslighting, a form of psychological manipulation that makes a person doubt their own reality or memory.

In practice, someone who is gaslit might be told that events they remember never happened, that their feelings are irrational, or that they are ‘overreacting’ without cause.

Gaslit is an adjective used to describe the state of the person who experiences this manipulation, and the term has broadened in popular usage beyond clinical settings.

The term traces back to the 1938 play Gas Light, by Patrick Hamilton, and the 1940s film adaptations that popularized the idea of dimming gas lamps to make someone question their perception.

From that story, the verb gaslight emerged and then the adjective gaslit, following typical English formation patterns where verbs become adjectives to describe affected people.
