tetanus

Etymology

It is inherited from Middle English tetanus, also tetane and tethanus,^[2] partly borrowed from Latin tetanus (“convulsive tension of the muscles”), a word used by Pliny, and partly its source, borrowed from Ancient Greek τέτανος (tétanos, “muscular spasm”).^[3][4][5] The Greek noun is a use of the adjective τετανός (tetanós, “taut, stretched”), a reduplicated formation from the zero grade of τείνω (teínō, “to stretch”),^[3][6] from Proto-Indo-European *ten- (“to stretch”).^[4][7][6] Etymonline, following Barnhart, explains the name by the violent spasms and stiffness of the muscles that mark the disease.^[4][5] Compare Middle French thetane, recorded from before 1365, and Italian tetano, from 1359.^[3] In late Middle English the word was also anglicized as tetane;^[8][9] Hoad dates the form tetanus itself only to the 16th century.^[8]

Earliest recorded meaning

A disease marked by spasms and rigidity of the muscles: before 1398, in John Trevisa's translation of Bartholomaeus Anglicus, which names it as the third kind of cramp.^[3][2] Barnhart dates the word 1392.^[5] An earlier English medical text, the Peri Didaxeon, perhaps composed in Old English, already uses Latin tetanicus for a person with this illness, calling it a Greek word.^[3]

Semantic evolution

In early use the word could also mean a single muscle spasm or cramp, or a case of the disease, a count use found from about 1400 and now rare.^[3][2] The disease sense was later tied to infection through a wound by the bacterium Clostridium tetani.^[10][11][12] From 1847 physiologists used the word for a sustained contraction of a muscle produced by rapidly repeated stimulation.^[3][10] The popular name for the disease is lockjaw.^[10][11]
