Pronunciation

  • 5th-century BC Attic: /ar.kʰâi̯.os/[1]
  • 4th-century AD Koine: /arˈçɛ.os/[1]
  • 10th-century Byzantine: /arˈçe.os/[1]

Forms

ᾰ̓ρχαῖος (arkhaîos) m (feminine ᾰ̓ρχαία, neuter ᾰ̓ρχαῖον); first/second declension[1] Ionic feminine ἀρχαίη, Aeolic ἄρχαος (Alcaeus).[2]

Etymology

It is formed from Ancient Greek ἀρχή (arkhḗ, “beginning”) + -ιος (-ios), “belonging to the beginning”.[1][3][4] Chantraine notes that ἀρχαῖος is an old derivative of the noun in its sense “beginning”, while almost all the other derivatives of ἄρχω (árkhō) belong to the sense “to rule”.[5] The DGE compares a Mycenaean a-ka-i-jo, with a question mark.[2]

Earliest recorded meaning

Its first known use is in a fragment of Hesiod, of an ancient law.[2][6]

Semantic evolution

It meant what has existed from the beginning or from long ago: primeval gods and laws in Aeschylus, Pindar and Sophocles, ancient clothing and the old bed of a river in Herodotus.[3][2][4] Chantraine distinguishes it from παλαιός (palaiós), “old”: ἀρχαῖος refers to origins, and it is unknown to Homer.[5] As a noun, οἱ ἀρχαῖοι were the ancients or ancestors, and the neuter τὸ ἀρχαῖον was the original sum, the capital of a loan.[3][5] In comedy the word turned to “old-fashioned, antiquated”, and Aristophanes uses it for someone simple or silly.[4] In the New Testament it is “old, of long standing”: the “ancient serpent” of Revelation and “a disciple of long standing” in Acts.[7]

It was borrowed as Latin archaeus.[8] In Modern Greek, the learned αρχαίος (archaíos) took its senses “former” and “antique” from French ancien and antique, and “senior” from English.[9] Its stem is in English Archaean, coined in geology in 1872.[10]
