Forms

intoxicō (present infinitive intoxicāre, supine intoxicātum); first conjugation[1][2]

Etymology

It is a Medieval Latin verb,[3][4] formed from Latin in- + toxicum (“poison”).[2][5] The DMLBS compares the Late Latin toxicō (“to poison”).[3]

Earliest recorded meaning

The earliest dated record is in a letter of Gerald of Wales of about 1213, in a figurative sense: affairs are everywhere poisoned by the vice of ingratitude.[3] Köbler's earliest date for it is 1216.[2]

Semantic evolution

The verb meant to kill or harm with poison, and also to make something poisonous, such as rivers and springs;[3][1] its past participle served as an adjective, “poisoned, tainted”.[3][1] From the start it was used figuratively of corrupting minds and causing spiritual harm: heretics poison words, and envy or false teaching poisons people and nations.[3][1] The regional dictionaries of Hungary, Poland and Bohemia record the same senses.[6][7][8]

Du Cange also gives it the sense “to seduce, bewitch”, said of minds.[9] English borrowed intoxicate in the mid-15th century, first meaning “to poison”;[5] “to make drunk” came in the 16th century.[5]
