Word History

Etymology

Middle English contagioun, borrowed from Anglo-French & Latin; Anglo-French contagiun, borrowed from Latin contāgiōn, contāgiō "contact, contact resulting in disease, infection, pollution," from contag-, variant stem of contingere "to be in contact with, arrive at, affect, fall to one's lot" + -iōn-, -iō, suffix of action nouns formed from compound verbs — more at contingent entry 1

Note: The vowel length in contāgiō is unexpected and difficult to explain; a similarly lengthened vowel is found in other deverbal derivatives with -ag- as a second member (compāgēs "bond, joint," from pangere, ambāgēs "circuitous path," from agere; see agent, pact).

First Known Use
