cauterize

Forms

• cauterise (UK)

Etymology

It is inherited from Middle English cauterizen,^[2][3] borrowed from Old French cauteriser,^[4][5][6][7] or directly borrowed from Late Latin cautērizō (“to burn or brand with a hot iron”),^[3][8][9] which Dictionary.com takes as the only source.^[9] The Middle English Dictionary gives a Medieval Latin source.^[2] That verb comes from Latin cautērium (“branding iron”),^[10][3][5] from Ancient Greek καυτήριον (kautḗrion, “branding iron”),^[10][3][11] a diminutive of καυτήρ (kautḗr, “burner”),^[3][12] from καίω (kaíō, “to burn”).^[3][12][11] Etymonline, the Oxford Dictionary of English, Hoad and Klein instead pass through καυτηριάζω (kautēriázō, “to sear with a hot iron”) on the way to Latin.^{[4][6][13][12]} Etymonline calls the Greek word for burning of uncertain origin.^[4]

Earliest recorded meaning

To burn or sear with a hot instrument, in surgery: before 1400, in the Middle English translation of Lanfranc, Þou muste cauterise þe vlcus aboue with an instrument of gold.^[2] Barnhart also dates it before 1400,^[3] Etymonline about 1400,^[4] and the OED, whose entry is not fully revised, gives about 1541, in Copland's Guy de Chauliac's Questyonary of Cyrurgyens.^[10]

Semantic evolution

The word began as a surgeons' term, and it was first used absolutely, without an object, in Gale's Certaine Workes of Chirurgerie of 1563.^[10] The figurative sense "to deaden, make insensible", applied to the conscience and the feelings, is recorded from 1587, in J. Hooker's chronicle of Ireland in Holinshed, and alludes to the seared conscience of 1 Timothy 4:2.^[10] A sense "to brand with a hot iron" lasted from 1591 to 1677.^[10] Johnson (1755) defined the verb simply as "to burn with the cautery", and quoted Timon of Athens: "Be cauterizing to the root o’ th’ tongue".^[14]
