Word origin
[1850–55; co- + variant]This word is first recorded in the period 1850–55. Other words that entered Englishat around the same time include: boneyard, headhunting, heavyweight, proletariat, runoffco- is a prefix meaning “with,” “together,” “in association,” sometimes with the derivedsense “auxiliary, subsidiary” (coenzyme; copilot), and, in mathematics and astronomy, with the sense “complement” (codeclination)
