gaslight n.

also gas-light, "light, or a provision for light, produced by combustion of coal gas; a gas-jet," 1808, from (illuminating) gas (n.1) + light (n.). Used through the 19th and into the early 20th century as street and domestic lighting. Related: Gas-lighted; gas-lighting; gaslighting.

As a verb meaning "to deliberately make a person believe that they are insane," by 1961, perhaps 1956. This sense is from the 1944 film Gaslight, in which a 19th century woman (played by Ingrid Bergman, who won an Academy Award) appears to be going mad. It is later revealed that her criminal husband has been convincing her that she is insane in order to discredit her observations of his activities. Among the observable clues has been the dimming of their home's gaslighting whenever (as she later learns) the husband goes secretly into the attic: he has convinced her that she is imagining this, until a family friend sees it, too, which confirms the clue that uncovers the crime.

Brian: Tell me. Is there anyone else in the house now, except us and Elizabeth?

Paula: No. Why?

Brian: The gas just went down.

Paula: You saw that too!

Brian: Why, yes.

Paula: Oh, then it really happens! I thought I imagined it!

Brian: But all it means is someone else has turned it on.

Paula: Oh, no, no. I thought that too. But every night, I’ve been all over the house, there’s never been another light turned on. At last I can tell this to someone! Every night when my husband goes out…

Brian: …The light goes down?

Paula: Yes.

Brian: And then what?

Paula: Well, then, I think I hear things. I watch and wait. Later on, the gas goes up again.

Brian: And he comes back?

Paula: Yes. Quite soon after. Always quite soon after.

[Gaslight, 1944]

The word seems to have received a boost in feminist literature in late 1970s.

… I had been told that my tonsillectomy was “not that bad” or that the dentist whose hands were between my legs was “fixing my teeth,” … My own favorite embodiment of this horror, still enjoyed by late-show insomniacs, is the 1944 film Gaslight, a tale which so impressed the public imagination that even today the word “gaslight” is used to describe an attempt to destroy another’s perceptions of reality and, ultimately, sanity itself. [Florence Rush, "The Best Kept Secret: Sexual Abuse of Children," 1980]

The sense evolved by 2016 to also mean "dismiss or discredit someone's viewpoint."

Entries linking to gaslight gas n.1 1650s, from Dutch gas, probably from Greek khaos "empty space" (see chaos). The sound of Dutch "g" is roughly equivalent to that of Greek "kh." First used by Flemish chemist J.B. van Helmont (1577-1644), probably influenced by Paracelsus, who used khaos in an occult sense of "proper elements of spirits" or "ultra-rarified water," which was van Helmont's definition of gas. Hunc spiritum, incognitum hactenus, novo nomine gas voco ("This vapor, hitherto unknown, I call by a new name, 'gas.'") [Helmont, Ortus Medicinae] Modern scientific sense began 1779, with later secondary specialization to "combustible mix of vapors" (1794, originally coal gas); "anesthetic" (1894, originally nitrous oxide); and "poison gas" (1900). Meaning "intestinal vapors" is from 1882. "The success of this artificial word is unique" [Weekley]. Slang sense of "empty talk" is from 1847; slang meaning "something exciting or excellent" first attested 1953, from earlier hepster slang gasser in the same sense (1944). Gas also meant "fun, a joke" in Anglo-Irish and was used so by Joyce (1914). Gas-works is by 1817. Gas-oven is from 1851 as a kitchen appliance; gas-stove from 1848. light n. "brightness, radiant energy, that which makes things visible," Old English leht (Anglian), leoht (West Saxon), "light, daylight; spiritual illumination," from Proto-Germanic leukhtam (source also of Old Saxon lioht, Old Frisian liacht, Middle Dutch lucht, Dutch licht, Old High German lioht, German Licht, Gothic liuhaþ "light"), from PIE root leuk- "light, brightness." The -gh- was an Anglo-French scribal attempt to render the Germanic hard -h- sound, which has since disappeared from this word. The figurative spiritual sense was in Old English; the sense of "mental illumination" is first recorded mid-15c. Meaning "something used for igniting" is from 1680s. Meaning "a consideration which puts something in a certain view" (as in in light of) is from 1680s. Short for traffic light from 1938. Quaker use is by 1650s; New Light/Old Light in church doctrine also is from 1650s. Meaning "person eminent or conspicuous" is from 1590s. A source of joy or delight has been the light of (someone's) eyes since Old English: Ðu eart dohtor min, minra eagna leoht [Juliana]. Phrases such as according to (one's) lights "to the best of one's natural or acquired capacities" preserve an older sense attested from 1520s. To figuratively stand in (someone's) light is from late 14c. To see the light "come into the world" is from 1680s; later as "come to full realization" (1812). The rock concert light-show is from 1966. To be out like a light "suddenly or completely unconscious" is from 1934. updated on December 07, 2022
