The story of the word

In Homer a θώραξ is armour, the bronze corslet a warrior straps on before fighting, and the body part took its name from the thing that covered it. Greek doctors then used it anatomically, Latin took it whole, and English had it as a medical term by the late 14th century. Entomologists later gave the name to the middle segment of an insect, the section that carries the legs and wings.
