induct

Etymology

It is inherited from Middle English inducten,^[2][3][4][5] borrowed from Latin inductus (“led in”), the past participle of indūcō (“to lead into, introduce”),^[3][5][6][4] the source of induce.^[2][7] Merriam-Webster Unabridged takes the participle as Medieval Latin,^[4] and the OED derives the verb from the participial stem induct-.^[8][9] The Latin verb is formed from in- (“into”) and dūcō (“to lead”), from Proto-Indo-European *dewk- (“to lead”).^[5][2]

Earliest recorded meaning

To put someone formally in possession of a church office or living: about 1380 in Wyclif's works in the OED,^[8] and probably about 1378 in Barnhart.^[3]

Semantic evolution

From the church the word passed to office in general, to install, in Hall's Union of 1548.^[8][3] P. Holland used it for leading someone into a place or matter in 1600, and for introducing someone to knowledge in 1603, in his translation of Plutarch.^[8][3] Sandys (1615) wrote of the Venetians inducting a custom, a use the OED records only there and Johnson (1755) quoted as his first sense, "to introduce; to bring in", next to the benefice sense.^[8][10] Farquhar (1707) used it for placing someone in a seat or room,^[8] and in 1832 Whewell, in a rare use, for reasoning by induction.^[8] The American military sense is dated to 1917 by Etymonline and to 1934 by the OED and Barnhart.^[5][8][3] An adjective induct, induced or initiated, had a short life, from before 1464 to 1545.^[8]
