rail

Etymology and origin of the English word rail

History Permalink

Rail, a bar, rail, a bird, and rail, to complain, are three different words from French.[1][2]

Pronunciation

  • IPA: /reɪl/[3]

rail1 bar

Confidence
Established
Formation
Borrowing
First attested
1294
Borrowed from
Old French reille via Middle English
Ultimate origin
Latin (rēgula)

Etymology

The bar is inherited from Middle English reyle, raile, borrowed from Old French raille, reille (“bolt, bar”),[4][1][2] from Vulgar Latin *regla, from Latin rēgula (“straight stick, rule”), a diminutive related to regere (“to straighten, guide”).[4][1] It is related to rule.[5][6]

Earliest recorded meaning

The railing of a ship: 1294–95 in Barnhart, and a bar fixed horizontally between supports about 1300.[1][4]

Semantic evolution

A rail forming part of a fence gave railings (1432–40) and the rails of a racecourse.[5][1] The first rails that vehicles ran on, pulled by horses, were of wood and date from the early 17th century.[5] Railroad (1757) and railway (1776) first meant a track for heavy wagons, and a track for locomotive trains from 1825 and 1832.[1] An iron or steel bar for train wheels is from the 1830s.[4] Used figuratively for thinness, as in thin as a rail, it is from 1872.[4] Off the rails, out of the normal condition, is from 1848.[4][5] The verb, to fence with rails, is from about 1385, in Chaucer.[1]

Etymology

To complain is inherited from Middle English railen, borrowed from Middle French railler (“to tease, joke”),[4][1][2] perhaps from Old Provençal ralhar “to chat, joke”, from Vulgar Latin *ragulāre “to bray”, from Late Latin ragere (“to roar”), probably imitative.[4][1] SOED traces it to a crossing of Latin rugīre “to bellow” with the source of bray.[7] It is related to rally “to tease”.[1][4]

Usage notes

An Old English hrægl “garment, cloak”, surviving as night-rail, a dressing gown, is a fourth, unrelated word.[10][6]
