Forms

inflammable (plural inflammables)[1]

Etymology

It is a learned formation from Latin īnflammō (“to set on fire”) with the suffix -able.[2][3][4] Rey and the TLFi think that Medieval Latin īnflammābilis, recorded about 1227, may have been its model.[3][2] Wiktionary instead derives it from Middle French inflammer with the same suffix,[1] a verb that the TLFi records from 1545.[2] The Latin verb is formed from in- and flammō (“to set alight”), itself from flamma (“flame”);[5] its inherited outcome is enflammer.[2][4]

Earliest recorded meaning

The TLFi's first record is from about 1390, soufre inflammable in Evrart de Conti's Problèmes d'Aristote (in a 15th-century manuscript);[2] Bloch and Wartburg date it to 1503.[6]

Semantic evolution

At first it was used in its literal sense, of what catches fire easily and burns quickly;[3][2] air inflammable was the 18th-century name for hydrogen, recorded in 1780.[3][7]

Féraud recorded the figurative sense, of a character quick to anger or passion, in 1787 (zèle inflammable, caractère inflammable).[2][3][5]
