Pronunciation

  • Classical: [ˈre.a.ɡoː][1]
  • Ecclesiastical: [ˈrɛː.a.ɡo][1]

Forms

reagō (present infinitive reagere, perfect active reēgī, supine reāctum); third conjugation[1]

Etymology

It is from Latin re- (“back, again”) + agō (“to drive, do”).[1][2]

Earliest recorded meaning

Georges and Gaffiot record it in Avienus' Aratea (line 668), in the sense “drive back again”,[2][3] but the TLL rejects it as a word that found its way into the dictionaries by mistake: the manuscripts there have cogunt.[4]

Semantic evolution

Wiktionary gives it in Late and Medieval Latin for “act on again, do again”, and in New Latin scientific writing for “react”.[1] Barnhart traces French réagir and English react to a Late Latin reagere, past participle reāctus.[5]

Timeline

  • mid 4th century AD – Avienus' Aratea, line 668, in the reading the older dictionaries print.[2][3][6][4]
  • 1611 – English reacting is first recorded, partly under the influence of French réagir.[5]

Meanings

Verb

  1. To drive back again (a doubtful reading in Avienus).[2][3][4]
  2. (Late Latin, Medieval Latin) To act on again, do again.[1]
  3. (New Latin) To react.[1]

Word family

  • reāctiō
