Word History and Origins

Origin of lithotripter1

First recorded in 1815–25; alteration of obsolete litho(n)triptor “instrument for crushing kidney stones,” derivative of litho(n)triptic “crushing kidney stones,” from New Latin lithontripticus, ultimately based on the Greek phrase (phármaka tôn en nephroîs) líthōn thryptiká “(drugs) breaking up stones (in the kidneys)”; thryptiká “crushing,” a derivative of thrýptein “to crush”; trip- by association with Greek trī́bein “to rub, knead, pound” (verbal adjective trīptós )
