  • /dɪskəˈnɛkt/[1]

Etymology

It is formed from English dis- + connect.[2][3][4][5][6][7] The OED compares the earlier disconnection, and Etymonline suggests the verb may be a back-formation from it.[2][3] The base verb comes from Latin connectō (“to fasten together”), from com- (“together”) and nectō (“to bind, tie”), from Proto-Indo-European *ned- (“to bind, tie”).[3] The noun, recorded from 1905, is the verb used as a noun;[2] Merriam-Webster takes the sense "disconnecting switch" (1926) as a shortening.[4]

Earliest recorded meaning

To break the logical connection or order of something, making it disjointed: 1751, in J. Roche's Moravian Heresy.[2] Etymonline and Merriam-Webster date the verb from 1770, in the sense "to sever the connection of".[3][4]

Semantic evolution

The physical sense, to break the connection between things or to detach them, is recorded from 1758.[2] In 1770 Burke used it for separating a person or thing from an association,[2] and in 1790 for dissolving a body into isolated parts, a use that soon died out.[2] Technical senses followed: cutting a device off from its electrical supply (1826), and cutting off a telephone or, later, computer connection (1877; intransitive from 1879).[2] From 1961 the intransitive verb also meant to withdraw from society or reality.[2][4] The noun, first a break in an electrical or telephone connection (1905), took in 1982 the sense of a lack of consistency or agreement, a discrepancy.[2][4][8]
