Forms
τρεῖς (treîs) (ordinal τρῐ́τος, adverbial τρῐ́ς)[1] Neuter τρία; genitive τριῶν, dative τρισί.[2][3] Doric (Gortyn) τρέες, Thera τρῆς, Heraclea and Delphi τρῖς; dative Delphian τρίεσσι, Aeolic τρίσσι, Hipponax τριοῖσι; old Attic and Gortynian accusative τρῖς, τρίινς.[2][4]
Etymology
It is inherited from Proto-Hellenic *tréyes, inherited from Proto-Indo-European *tréyes (“three”).[1][5] Cognate with Sanskrit त्रयः (tráyaḥ), Latin trēs, Gothic 𐌸𐍂𐌴𐌹𐍃 (þreis), Old Armenian երեք (erekʻ) and Old English þrēo.[1][5][4]
The old accusative *trins survives as Gortynian τρίινς (tríins), made disyllabic after the genitive and dative, and contracted τρῖς (trîs); the Ionic-Attic accusative τρεῖς was taken from the nominative.[5][4] The neuter τρία (tría) continues *trih₂.[5] The adverb τρίς (trís, “three times”) agrees with Latin ter, and the ordinal τρίτος (trítos, “third”) with Tocharian B trite.[5] Mycenaean already has the compound stem, in Mycenaean Greek ti-ri-po (“tripod”).[6]
Earliest recorded meaning
From Homer on it is the ordinary word for “three” (Iliad 15.187).[2][3][7]
Semantic evolution
Three was a sacred and lucky number from early times, above all for the Pythagoreans, as Aristotle reports.[2][8] Pindar's “three words” (Nemean 7.48) was proverbial for a brief speech, and Euripides' διὰ τριῶν, “by three”, meant thrice over, utterly (Orestes 434).[2] Simplicius calls the trivium “the course through three”, and a papyrus of the 3rd century AD has τρία τρία, “by threes”.[2]
In the New Testament Paul speaks of faith, hope and love as “these three” (1 Corinthians 13:13).[9] Coptic borrowed the neuter as ⟨ⲧⲣⲓⲁ⟩, attested about AD 600.[10] The word continues in Modern Greek τρεις (treis), neuter τρία (tría).[11][6]
