The Origin of Gaslighted or Gaslit

The words come from the verb gaslight, which itself was popularized from the title of the 1938 British play Gas Light and its later film adaptations.

• In the story, a husband manipulates his wife by subtly dimming the gas lights in their home and denying it, making her doubt her own senses.
  
• The verb gaslight evolved from this idea of causing someone to doubt their memory, perception, or sanity.
  
• As the term entered psychological and everyday English, people began asking: How do you form its past tense?
  

English does not have a single body that regulates usage, so sometimes both older and newer forms coexist. Dictionaries like Merriam‑Webster list gaslighted as the verb’s past tense, while older uses of gaslit come from traditional grammar of compound verbs like “to light.”
