Forms

medeor (present infinitive medērī); second conjugation, deponent, no perfect or supine stems[1]

Etymology

It is inherited from Proto-Italic *med-ē-, from Proto-Indo-European *med- (“to measure”).[2][1] De Vaan explains the meaning as a shift from “to measure” through “to judge” to “to be a healer”, the verb perhaps being built on a noun *medos- “judgement”, the source of modus.[2] The OLD links it with meditor.[3]

Cognate with Old Irish midithir (“measures, judges”), Ancient Greek μέδομαι (médomai, “to care for, think of”) and Gothic 𐌼𐌹𐍄𐌰𐌽 (mitan, “to measure”).[2]

Earliest recorded meaning

It is found from Cato onwards.[2][4] Afranius has a character say arquato medeor, “I cure the jaundiced”.[3]

Semantic evolution

It meant to heal or cure, usually with the dative, as when Cicero says a doctor must know not only the illness of the patient he wants to cure but his habits in health.[3] Pliny uses it for treating wounds.[5]

Figuratively it meant to remedy or relieve, as Cicero's plea to the jury to “heal the religious scruples of our allies”, and to make good a shortage of grain.[3] From it came medicus “doctor”, medicīna and remedium.[2] English medicine and remedy came through Old French about 1200.[6]

  • c. 250–184 BC – Plautus uses its derivatives medicus and medicina.[2][4]
  • 81–43 BC – Cicero uses it for healing and for remedying.[3][4]
  • c. 1200 – English medicine and remedy are first recorded.[6]
