chloroform (n.)

"trichloromethane," volatile liquid used as an anaesthetic, 1835, from French chloroforme, a hybrid coined 1834 by French chemist Jean-Baptiste Dumas (1800-1884) from chlor-, combining form meaning "chlorine" (see chlorine) + formique "formic (acid)" (see formic (adj.)). As a verb, from 1848, the year its anaesthetic properties were discovered. Related: Chloroformed.
