Etymology

Origin of cauterize

1350–1400; Middle English < Late Latin cautērizāre to brand, equivalent to cautēr- (< Greek kautḗr branding iron, equivalent to kau-, variant stem of kaíein to burn ( cf. caustic), + -tēr agent suffix) + -izāre -ize

Explanation

To cauterize is to seal off a wound or incision by burning it or freezing it, usually with a hot iron, electricity, or chemicals. Metaphorically, cauterize means to make less sensitive to feelings and emotions. Cauterize is usually a medical term. In surgery, using an electrical tool to cauterize the incision seals off blood vessels, resulting in a cleaner operation that heals more easily. Extreme cold, electricity, and chemicals are also used outside the body cauterize, or "burn off," warts and vessels that cause nosebleeds.
