Pronunciation

  • IPA: /d͡ʒɛl/[1]

Etymology

It is a shortening of gelatin,[2][3][4] perhaps influenced by the earlier jell (1870), from jelly.[3][5] Etymonline credits the word to the Scottish chemist Thomas Graham.[5] The verb is from the noun,[3] but the OED's revised entry (2026) also includes in the verb the senses of the older jell, to set like jelly, shortened from jelly.[6]

Earliest recorded meaning

A semi-solid colloidal system in chemistry: 1899.[3][5][7]

Semantic evolution

The verb, of a colloid, to become a gel, is dated 1902 in Etymonline, 1908 in the OED and 1917 in Barnhart and Merriam-Webster.[5][6][3][8] The figurative senses, to take definite shape and to work well together, belong to jell (from 1905 and 1920),[6] and are now often spelled gel;[6][8] Etymonline dates the figurative gel to 1958.[5] Hair gel, a jelly for styling the hair, is from 1958,[5][7] and the verb, to apply it, from 1979.[6]
