  • US: /ˌʌndɚˈteɪk/[1]

Etymology

It is inherited from Middle English undertaken,[2][3][4] formed from Middle English under- + taken (“to take”),[5][2][6] modelled on underniman (“to receive, undertake”).[5][7][6] It replaced that verb and underfōn in the same senses.[6] The Old English verb is cognate with Dutch ondernemen and German unternehmen,[2][7] and Klein sees the Middle English verb as a loan translation of it.[7] The verb take came into late Old English from a Scandinavian source such as Old Norse taka (“to take, grasp”).[2][8] French entreprendre, from entre (“between, among”) and prendre (“to take”), is a parallel formation.[2][7][9] Etymonline suggests that under here may be the same element as in understand.[2]

Earliest recorded meaning

To take by craft, to entrap or seize upon: about 1175, in the Ormulum, a sense obsolete by 1470.[5][2][6] Before 1250 it also meant to accept or receive willingly.[5][8]

Semantic evolution

The modern sense, to take something upon oneself or take it in hand, appears around 1340 in Richard Rolle's Psalter,[5] and Etymonline dates "to set about doing" to about 1300.[2] From the 1380s it took an infinitive, as in Chaucer; from 1393 it could also mean to promise or assert something formally, as in Langland.[5] Chaucer used the verb 29 times, for undertaking an enterprise and for declaring or affirming.[10] Middle English also used it for rebuking (from 1377), for receiving and for understanding, all now obsolete.[5][6] The sense of standing surety for someone dates from the 16th century.[8] Johnson (1755) defined it as "to attempt; to engage in".[11] The derivative undertaker first meant a helper or contractor, and was later narrowed to a person who arranges funerals.[8][9]
