Pronunciation

  • /ɪŋˈkɹoʊt͡ʃmənt/, /ɛŋˈkɹoʊt͡ʃmənt/[1]

Etymology

It is inherited from Middle English encrochement,[2][3] borrowed from Anglo-Norman encrochement,[3][4][5] recorded in Anglo-Norman from 1388[6] (the OED's date is 1437),[7] with the sense of usurping rights or extending one's land illegally.[6] The OED instead treats it as formed within the language from English encroach + -ment,[7] and Barnhart allows that for some uses;[4] Etymonline gives both explanations.[8] The base verb is from Old French encrochier (“to seize, fasten on”),[7][8][4][9] from en- and croc (“hook”),[7][8][10][9] from Old Norse krókr (“hook”),[9][8] the source of crook.[9][8]

Earliest recorded meaning

A structure obtruding into a watercourse: Coventry records of probably 1469 forbid narrowing the river with “weeres, demyngess, encrochementes”.[2][4] Etymonline gives the mid 15th century for this sense.[8] The OED's first record of the action of encroaching is from 1523, in Fitzherbert's Boke of Surueyeng.[7]

Semantic evolution

The image is of something that seizes with hooks, and the verb's use for intruding on what belongs to another developed only in the 16th century, out of “seize wrongfully”.[9][8] The OED singles out a legal use of the noun.[7] Johnson (1755), following Cowell, explained it as an unlawful gathering in upon another: one of two neighbours pressing too far on the other's ground, or a lord taking three shillings where the rent is two.[11] Webster (1828) stressed the gradual, silent advance on another's rights or territory, and added what is taken in that way.[12] A rare noun encroach with the same meaning appears from 1611.[7] The American Heritage Dictionary (5th ed.) adds a sense from American football, a player entering the neutral zone and touching an opponent before the snap.[10]
