Did You Know?
If you have a burning desire to know the origins of caustic, you're already well on the way to figuring it out.
Caustic was borrowed into English in the 14th century from the Latin causticus, which itself derives from the Greek kaustikos. Kaustikos, in turn, comes from the Greek verb kaiein, meaning "to burn."
Other kaiein descendants in English include cautery and cauterize, causalgia (a burning pain caused by nerve damage), and encaustic (a kind of paint that is heated after it's applied).
