Forms
τέλειος (téleios) m (feminine τελείᾱ, neuter τέλειον); first/second declension[1]
Etymology
It is formed from Ancient Greek τέλος (télos, “end, fulfilment”) + -ιος (-ios).[1][2] How the suffix was added is much discussed: Beekes considers *τελεσ-ος (*teles-os), *τελεσ-ϝος (*teles-wos) and *τελε-ιος (*tele-ios).[2] The Πάπυρος dictionary derives it from the stem *τελεσ- (*teles-) of the neuter in -s with the suffix *-yo- (*-yo-), with loss of the /s/, and Babiniotis allows either that suffix or *-ϝο- (*-wo-).[3][4] Homer has only this form; τέλεος (téleos) is the only form in Herodotus, and there are Cretan τέληος (télēos) and Coan τέλεως (téleōs).[5][2]
Beekes thinks that the noun has a double origin: in the sense “end, goal” it comes from τέλομαι (télomai), the by-form of πέλομαι (pélomai, “to come to be”), from Proto-Indo-European *kʷel- (“to turn”), and first meant a turning point.[2]
Earliest recorded meaning
Homer uses it of sacrificial goats, “perfect, without blemish”, and the superlative of the eagle, the bird whose omen is surest to be fulfilled.[6][5]
Semantic evolution
Of animals and people it means full-grown: Herodotus distinguishes full-grown victims from sucklings, and the grammarian Pausanias says that married people were called τέλειοι, the explanation given for the Hera Teleia of Stymphalus.[5][7] Of persons it means accomplished, perfect in their kind (Isocrates, Plato), and Aristotle speaks of perfect virtue and friendship and calls the syllogism of the first figure perfect, the others imperfect.[5][7] In dialect inscriptions it means fully constituted and valid, of an assembly, and authoritative or final.[5]
In Attic inscriptions only τέλεος is found until the end of the 3rd century BC; τέλειος appears there in the early 2nd century BC, and the papyri use it often.[5] In the New Testament it means perfect in goodness, of a work, a gift, love, the law, and of people mature in faith.[8][7] It was borrowed as Coptic ⲧⲉⲗⲉⲓⲟⲥ (teleios), found in manuscripts from 264 AD on in all the main dialects.[9]
Modern Greek uses τέλειος (téleios), “perfect”, as a learned word; the sense “without defects” was already ancient.[10][4]
