Omega is the name of the last letter in the Greek alphabet, representing the uppercase Ω and lowercase ω. Often seen as a symbol of completion, it is the twenty-fourth and final letter of the Greek alphabet. In the Greek numeric system (isopsephy), omega has a value of 800. The letter originally meant ō̂, but it was later expanded to ō̂ méga ('big o') in the Middle Ages to distinguish it from omicron, whose name means 'small o'. In modern Greek, the name has fused into ωμέγα (oméga). In phonetic terms, the Ancient Greek Ω represented a long open-mid back rounded vowel [ɔː], in contrast to omicron (ο) which represented the close-mid back rounded vowel [o]. In modern Greek, both omega and omicron represent the mid back rounded vowel [o̞]. The letter omega is transliterated into Latin-alphabet languages as ō or o. Famous associations include the biblical verse from the Book of Revelation where God states, 'I am the Alpha and the Omega' (εἰμὶ τὸ Ἄλφα καὶ τὸ Ὦ, Revelation 1:8), referring to the first and last letters of the Greek alphabet to signify divine eternity. This phrase is used in Jewish and Christian religious contexts as a metaphor for Jesus Christ's universality. As a given name, Omega is rare, but carries profound symbolic weight. Notable bearers with the name are uncommon in historical records unless attached exclusively to pious monastic or fictional characters. Relatives of the name include the letter's phonetic companions. The use of Omega as an endonym for the beginning/ending parallel likewise forged the basis for interlinear letters such as: none currently present for names derived directly from letters.
