Forms

• anaesthetic (UK)

Etymology

It is from Ancient Greek ἀναίσθητος (anaísthētos, “without feeling, insensible”) with the suffix -ic.^{[2][3][4][5][6]} The Greek adjective is formed from ἀν- (an-, “not, without”) and αἰσθητός (aisthētós, “perceptible, sensible”), from αἰσθάνομαι (aisthánomai, “to perceive, feel”),^[5][6][2] and is related to ἀναισθησία (anaisthēsía, “lack of sensation”), the source of anesthesia.^[3][2][4] Etymonline gives its Greek senses as insensate or without feeling, but also senseless, tactless and stupid.^[3] Merriam-Webster refers the Greek verb to the same root as audible.^[5] According to Barnhart, the English adjective was proposed in 1846 by the American physician and author Oliver Wendell Holmes (1809–94),^[2] and Dictionary.com marks it as an Americanism of 1840–50.^[7]

Earliest recorded meaning

Merriam-Webster Unabridged dates the adjective, in the sense able to produce anesthesia, to 1823.^[5] Etymonline records it first in 1846 for "insensible", and in 1847 for "producing temporary loss of sensation";^[3] Barnhart also dates it to 1846, in the spelling with -ae-.^[2]

Semantic evolution

The word spread with the first surgical use of anesthesia, which Etymonline dates to 1846.^[3] The noun, a substance that produces anesthesia, is dated 1845 by Merriam-Webster Unabridged^[5] and 1848 by Merriam-Webster's Collegiate and Barnhart;^[8][2] Etymonline credits its first use in the modern sense, in 1848, to the Scottish doctor James Young Simpson (1811–1870), a pioneer of chloroform in surgery.^[3] Both the adjective and the noun were extended to dullness of feeling: the adjective to a lack of awareness or sensitivity,^[8][5][9] the noun to anything that brings relief from pain or worry.^[8][5] The spelling anaesthetic is the usual one in British English, and anesthetic the usual one in the United States.^[10][11] In British use the plural anaesthetics also names the study or practice of anaesthesia.^[12]
