Forms

medicāmentum n (genitive medicāmentī); second declension[1]

Etymology

It is from Latin medicō (“to heal”) + -mentum, a noun of means, “that by which one heals”.[2][1][3] The verb medicō belongs with medeor (“to heal”),[4] which goes back to Proto-Italic *med-ē- and Proto-Indo-European *med- (“to measure”), with a shift from “measure” to “give a cure”.[4] Cognate with Old Irish midithir (“measures, judges”), Ancient Greek μέδομαι (médomai, “to care for”) and Gothic 𐌼𐌹𐍄𐌰𐌽 (mitan, “to measure”).[4]

Earliest recorded meaning

De Vaan and Köbler date it from Plautus,[4][5] who tells how Medea made old Pelias young again with a drug and her poisons.[2]

Semantic evolution

It is any drug given for its effect on the body, and with a genitive a drug that produces something, as Seneca's “drug of immortality”.[2] Cato uses it of a remedy for oxen, and Cicero figuratively of money as Verres' cure-all.[2] Malum medicamentum is a poison, as in the elder Seneca.[2] It is also a cosmetic, in Fronto, a preparation for plants, land or wine, as Columella's oil dregs that kill worms in trees, and a dye, in Seneca.[2]

Church Latin glosses it “drug, remedy, medicine”.[6]
