Pronunciation

  • 5th-century BC Attic: /ár.kʰɔː/[1]
  • 4th-century AD Koine: /ˈar.xo/[1]
  • 10th-century Byzantine: /ˈar.xo/[1]

Forms

ᾰ̓́ρχω (árkhō) [1]

Etymology

Its origin is disputed.[2][1] Klingenschmitt proposed a present Proto-Indo-European *h₂r̥-sḱé- (“to be first in order and rank”), and Matzinger supported this, deriving Old Armenian արքայ (arkʻay, “king”) from the same root.[2] Wiktionary notes that the Armenian word is generally thought to be a loan from Greek.[2][1] The LIV, after Tichy, sets up *(h₂)rgʰ-sḱé- from a root *regʰ- (“to straighten up”), comparing Middle High German words for “rise, stir” and Lithuanian regė́ti (“to see, watch”).[3][2] Beekes accepts this only with a root beginning in a laryngeal, since no Indo-European root began with /r/ and the augmented imperfect points that way.[2][3] The DGE thinks of *ser-gʰ- (“to protect”), with a shift of sense to “be first, guide”.[4]

Frisk and Chantraine only compare ὄρχαμος (órkhamos) “leader”.[2][5] Furnée took the /a/ : /o/ variation between the two as a sign of substrate origin, but Beekes finds this unconvincing.[2][5] Chantraine notes that the uncertain etymology does not fix the first meaning, which seems to have been “to go first, take the initiative”.[5]

Earliest recorded meaning

It is found from the Iliad on, in both its senses: “to lead the way, begin”, as of beginning a war or a speech, and “to rule”, as when Agamemnon commands a hundred ships.[2][6][7] In Homer the active is more frequent than the middle.[6]

Semantic evolution

The verb expresses being first, either in time (to begin) or in authority (to rule).[8] In Attic prose the middle prevails for “begin”, especially where a person's own action is stressed, and the active for “rule”, with the genitive of what is ruled.[6][5] Set phrases include “to begin a war”, said of the aggressor, and “to strike the first blow”.[6] In the middle it was also a religious term for making the first offering of a sacrifice.[6][8] Its participle ἄρχων (árkhōn) “ruler” became a noun, continued by Modern Greek άρχοντας, and the noun ἀρχή (arkhḗ) and the many compounds in ⟨-αρχος⟩ and ⟨-αρχία⟩ belong to the same stem.[7][5]

In the New Testament the aorist middle with an infinitive is often a periphrasis for the imperfect, as in “he began to teach”.[8][9] Medieval Greek formed Modern Greek αρχίζω (archízo, “to begin”) from ἀρχή.[10] The Modern Greek άρχω (árcho) is a learned word meaning “to govern”, used only in the present, and οι αρχόμενοι “the governed” is set against the rulers.[10]

Timeline

  • Homer – The Iliad uses it for leading the way, beginning an action and ruling.[6][11]
  • Before the 6th century BC – Hesiod opens his Theogony with “let us begin”.[12]
  • 5th century BC – Thucydides uses “to begin a war” of the aggressor.[6][4]
  • 5th century BC – Antiphon uses it of striking the first blow.[6][4]
  • 1st century AD – The Gospels use the aorist middle with an infinitive for an action in progress.[9][8]
  • Medieval Greek – The verb αρχίζω “to begin” is formed from ἀρχή.[10]
  • Modern Greek – It survives as a learned verb meaning “govern”.[10]
