Gaslighting shone much brighter than you would expect a gaslight to shine on November 8th, 2018, after New York Times writer Binyamin Appelbaum took to Twitter to vent about it, appearing to cast doubts on the existence of the word. Respondents to Appelbaum’s tweet seemed uncertain as to whether he was attempting to gaslight them, or was merely displaying a deep and abiding ignorance of the way in which language functions.
I don't know what the word 'gaslighting' means and I wish people would stop using it. There are plenty of actual English words.— Binyamin Appelbaum (@BCAppelbaum) November 8, 2018
We define gaslighting as “to attempt to make (someone) believe that he or she is going insane (as by subjecting that person to a series of experiences that have no rational explanation).”
The modern sense of gaslighting comes from Gas Light, a play (1938) by British writer Patrick Hamilton, subsequently made into British and American films entitled Gaslight (1940 and 1944), in which a man attempts to trick his wife into believing that she is going insane. Used as a verb and verbal noun, gaslighting has been in this figurative use since at least 1956.
Naturally, gaslighting may also be defined more literally as “lighting by means of gaslight.” This older sense dates back to the beginning of the 19th century.
These, however, were but imperfect trials, when compared with those made in 1805 at Messrs. Philips and Lee’s cotton mills at Manchester; and upon the results of which, all subsequent procedures, with regard to gas lighting, may be said to be founded.
