Pronunciation

  • 5th-century BC Attic: /plɛː.tʰy̌ːs/[1]
  • 4th-century AD Koine: /pliˈθys/[1]
  • 10th-century Byzantine: /pliˈθys/[1]

Forms

πληθῡ́ς (plēthū́s) f (genitive πληθῠ́ος); third declension[1] The long ῡ of the nominative and accusative singular is short in the other cases; the epic dative is πληθυῖ (plēthuî).[2][3] The word is Ionic, Cretan and Locrian, and later Hellenistic, and Locrian and Boeotian have a parallel πλήθα (plḗthā).[4]

Etymology

It belongs to the family of πίμπλημι (pímplēmi, “to fill”), πλήθω (plḗthō, “to be full”) and πλῆθος (plêthos, “mass, crowd”), whose root is from Proto-Indo-European *pleh₁- (“to fill”).[4][1][5] Beekes takes the theta of πλῆθος (plêthos) and πλήθω (plḗthō) for a suffix found in rather young formations, but compares πληθύς with Latin plēbēs (“the common people”), from Proto-Indo-European *pleh₁-dʰuh₁-.[4] Wiktionary reports his reconstruction of the nominative as *pléh₁dʰuh₁s, with an original accusative that Greek replaced, and notes that the Latin word may point to a slightly different stem; the exact pre-form is unclear.[1]

Pokorny likewise sets the Ionic word beside the Latin one.[5] Further related words are πολύς (polús, “much, many”) and Latin plērus (“for the greater part”).[4]

Earliest recorded meaning

It is first found in Homer, where it means the whole body or number of a people or an army, and especially the common mass of the host as opposed to its leaders, a throng in battle, and numerical strength.[6][7] In the second book of the Iliad it already takes a plural verb as a noun of multitude.[2]

Semantic evolution

LSJ treats it as the Ionic counterpart of πλῆθος (plêthos).[2] Tyrtaeus uses it for the superior numbers of an army.[3] In the law code of Gortyn it is used like δῆμος (dêmos) for the people, and a Locrian inscription of the 5th century BC uses it for the majority that carries a decision.[2]

In later prose it reappears in the dialogue Axiochus ascribed to Plato and in the Third Book of Maccabees, where it means a crowd.[2][8] Polybius uses it for the majority of people and for the number of troops, and Plutarch for the bulk of an army.[3][2] Dionysius of Halicarnassus uses it as the Greek word for the Roman Latin plēbs.[2]

Medieval vernacular Greek kept it, also in the form πληνθύς (plinthýs) with an added nasal, for a multitude, the common people and abundance.[9] In 1806 Dimitrios Govdelas used it in his algebra as a mathematical term for an abstract plurality.[10] It survives as a learned word, Modern Greek πληθύς (plithýs), for a great quantity of people or things.[11][12]
