Pronunciation

  • Classical: [ˈrɛi̯.ki.oː], [rɛjˈjɪ.ki.oː][1]
  • Ecclesiastical: [ˈrɛi̯.t͡ʃi.o], [reˈjiː.t͡ʃi.o][1]

Forms

reiciō (present infinitive reicere, perfect active reiēcī, supine reiectum); third (-iō variant) conjugation[1]

Etymology

It is formed from Latin re- (“back”) + iaciō (“to throw”).[2][1] De Vaan derives iaciō from Proto-Italic *jaki- and the root Proto-Indo-European *(H)ieh₁- (“to throw, let go”), cognate with Ancient Greek ἵημι (híēmi, “to send, throw”).[3] The TLL explains the spelling: the single ⟨i⟩ between vowels was taken for a double consonant, so the first syllable counted as long, ⟨rēiciō⟩.[4] Terence and Virgil also scan the first two syllables as one.[2]

Earliest recorded meaning

Plautus, Persa: a slave fears that he cannot drive the oxen back into the stall to keep them from straying (in bubīle rēicere).[2]

Semantic evolution

The first sense is throwing or driving something back where it came from: a contrary wind drives a ship back to port (Cicero), and Horace has Hannibal's threats turned back on himself.[2] It also means driving away or repelling an attack, as Virgil's shepherd drives the goats back from the river, and throwing something behind one, especially a garment, or slinging the shield over the back.[2] In the courts it is to reject a juror (Cicero), and generally to reject, refuse or scorn a thing or a person.[5][1] Lastly it is to refer a matter to someone else and to postpone it.[5][1]

Church Latin glosses it “throw back, reject, repel, cast away”.[6] English reject comes from the frequentative ⟨rēiectō⟩ and the participle ⟨rēiectus⟩.[7]

  • 81–43 BC – Cicero of a ship driven back by a storm.[2][8]
