Background / Comments
A gaslight (a noun) is just a light that feeds off of gas; they predated electric lights. Our word comes from the 1944 film Gaslight. This is the United States film; a British film was made in 1940. Both of the films came from a 1938 play called “Gas Light” by Patrick Hamilton. In all of these, a man attempts to convince his wife that she in insane by (among other things) secretly causing the gaslights in the house to dim and brighten. He claims that she is imagining it.
