router1 woodworking tool

Etymology

The woodworking tool is formed from English rout + -er,[2][3][4][5] from the verb rout, to dig with the snout, to poke about, and in carpentry to gouge or scoop out.[6][5][7] That verb, recorded from the mid-16th century, is an irregular variant of root, to dig with the snout,[4][8][9] which is from Middle English wroten, from Old English wrōtan (“to root up”).[5]

Earliest recorded meaning

A tool for removing loose wood from a groove or recess: 1818, in the Transactions of the Society of Arts.[2][3][5][4] Dictionary.com dates it to 1840–50.[9]

Semantic evolution

Barnhart records the carpenters' sense of the verb rout, to hollow or gouge out, from 1726, a century before the tool's name.[6] By 1833 router was the name of hand tools for cutting grooves, rebates and mouldings,[2] and the router plane, a two-handled plane with a cutter below its sole, belongs here.[7][3] From 1872 it was also a machine with a fast-spinning cutter for the same work, used too in milling metal and in photoengraving.[2][3] The verb router, to cut with a router, followed in 1890.[2]

router2 network device

Etymology

The device is formed from English route + -er,[3][2][9] from the verb route, to send along a particular course.[5][2] The noun route is from Old French rute (“road, way, path”), from Latin rupta (“broken”), as in a road broken or cut through, the feminine past participle of rumpō (“to break”).[5][8]

Earliest recorded meaning

One that routes, such as a clerk who sorts articles by delivery route: 1903 in Merriam-Webster,[3] 1900–05 in Dictionary.com.[9]

Semantic evolution

The verb route was first used in 1890, of marking a railway ticket for a given route, and by 1948 of directing an electrical signal or a telephone call over a circuit.[5] Router followed that path: from 1968 it named a device, circuit or algorithm that sends incoming signals on to their destinations, and in particular a device that forwards data packets across a network.[2][10] In horse racing, a router is also a horse trained for long-distance races, recorded from about 1951.[3]

Timeline

  • 1890 – the verb route, of a railway ticket.[5]
  • 1903 – one that routes, a clerk sorting articles by route.[3]
  • c. 1951 – a horse trained for distance races.[3]
  • 1968 – a device that directs signals or data packets to their destinations.[2]

Meanings

Noun

  2. A person who sorts articles according to delivery routes.[3]
  3. A racehorse trained for long-distance races; compare sprinter.[3]

Usage notes

The woodworking tool is pronounced to rhyme with shouter in both Britain and America; for the network device, British speakers usually say /ˈruːtə/ and Americans /ˈraʊdər/.[2][11] Merriam-Webster gives both /ˈrü-tər/ and /ˈrau̇-tər/ for the second word.[3] The OED also records several older, obsolete nouns spelled router: a robber or ruffian (c. 1300–1540), a snorer (1440–1611), and a member of a riotous crowd or rout (from 1584, now rare).[2][7]
