  • US: /ˈsɝkətɹi/[1]

Etymology

It is formed from English circuit + -ry,[2][3][4] the noun being used in its electrical sense.[2] Circuit is from Middle English circuit (“circumference”),[5] from Old French circuit, from Latin circuitus (“a going around”), from circumeō (“to go around”),[5][3][2] formed from circum (“round”) and eō (“to go”),[2][3] from Proto-Indo-European *ei- (“to go”).[3][5] The suffix -ry is a reduced form of -ery.[3]

Earliest recorded meaning

The plan or the components of an electric circuit, or a system of such circuits: 1946, in the journal Electronic Engineering.[2][6][7][3] Dictionary.com dates it to 1945–50.[4]

Semantic evolution

The word builds on the electrical sense of circuit, the arrangement by which a current passes between two poles, recorded from 1746.[3] From the plan of an electric circuit or network, as in a radio or television receiver, it was extended to the components themselves,[6][7] and later to the network of interconnected nerve cells in the nervous system, especially the brain.[6][7]
