Pronunciation

  • /ˈflæʃˌlaɪt/[1]

Etymology

It is formed from English flash + light.[2][3][4] The OED takes the first part as the noun flash, Etymonline as the verb.[2][3]

Earliest recorded meaning

A light that flashes briefly and regularly, used for signals and in lighthouses: 1829, in the Aberdeen Journal.[2] Etymonline and Merriam-Webster date the word to 1886.[3][5]

Semantic evolution

The lighthouse light came first.[2][3] In photography the word was used of a device or preparation giving a brief, intense light for taking pictures, from 1887 in the OED and by 1892 in Etymonline,[2][3] and Merriam-Webster also has the sense of a photograph taken by such a light.[6] The portable electric lamp powered by batteries in a cylindrical case is recorded from 1901 in the OED, from 1905 in Etymonline.[2][3] This sense is chiefly North American: in Britain the lamp is usually a torch.[2][7][3] The figurative use, something that throws light on a situation, dates from 1898, and the verb, to light up or photograph with a flashlight, from 1901.[2]
