Pronunciation
Forms
τρῐ́τος (trítos) m (feminine τρῐ́τη, neuter τρῐ́τον); first/second declension[1] Aeolic τέρτος (tértos); epic and poetic enlarged τρίτατος (trítatos), Aeolic τέρτατος (tértatos) in Pindar.[2][3] The Mycenaean ti-ri-to on a Knossos tablet (KN Dv 1386) is read as a personal name, Tritos.[4]
Etymology
It is inherited from Proto-Hellenic *trítos, formed from *tréyes (“three”) with the ordinal suffix *-tos.[1] Beekes counts it among the inherited forms of the numeral τρεῖς (treîs, “three”), and Wiktionary traces it to Proto-Indo-European *tr̥tyós ~ *tritós, an ordinal formed like those with *-tós.[2][1] It is built on the weak stem ⟨τρι-⟩ of the numeral with the suffix ⟨-τος⟩ of πέμπτος (pémptos) and ἕκτος (héktos).[5][6]
It matches exactly Tocharian B trite and Tocharian A trit, while Latin tertius has an added suffix *-yos.[2][7] Pokorny also compares Lithuanian trẽčias, with ⟨tre-⟩ for ⟨tri-⟩.[8] The Aeolic τέρτος (tértos) comes from the same form by a change of vowel and an exchange of places between the vowel and the /r/, as in κρίκος (kríkos) beside κίρκος (kírkos).[8][6] The epic τρίτατος (trítatos) was enlarged on the model of τέτρατος (tétratos).[3]
Earliest recorded meaning
From Homer on it means “third”, the last of three: the Iliad speaks of the third day and the third set of prizes, and uses the neuter τὸ τρίτον (tò tríton) for “in the third place” and “for the third time”.[9][10]
Semantic evolution
The third often closes a series, and several fixed uses grew from this: τρίτος αὐτός (trítos autós) “himself the third”, that is, with two others; τρίτη (trítē) (with or without ἡμέρα (hēmérā)) for the day after tomorrow; τὰ τρίτα (tà tríta) for the offerings made on the third day after a funeral; and the third libation, poured to Zeus the Saviour.[10][11] In the theatre “to speak the third part” meant to take the least important role, a phrase Demosthenes uses.[11][10] Other words were understood with the feminine: the third string of the lyre, the third blow, a third part of a coin or weight.[10]
In the Septuagint and the New Testament the neuter means “for the third time”, and the Second Epistle to the Corinthians speaks of the “third heaven”.[10][12] Coptic borrowed it as ⲧⲣⲓⲧⲟⲥ (tritos).[13]
Medieval and Modern Greek keep the word, and the feminine Τρίτη (Tríti) became the name of Tuesday, the third day of the week.[6] Some Modern Greek uses of τρίτος (trítos) are learned calques on French tiers and English third.[14]
