Tetanus

/ˈtɛtənəs/noun

A bacterial infection that locks the muscles in painful rigid spasm, often starting at the jaw.

The Greek roots

τέτανος
tétanos
muscular spasm
+
τείνειν
teínein
to stretch

Literally: the stretching

The story of the word

Greek physicians used τέτανος for the rigidity itself, and Hippocratic writings describe the locked jaw and the arched back with unpleasant accuracy. The cause, Clostridium tetani in soil and manure, was not identified until the 1880s. So the disease carries a name that describes what a body does rather than what infects it, which is why the everyday name is still lockjaw.
