Lexicon :: Strong's G1 - alpha

Α, α, ἄλφα, τό, the first letter of the Greek alphabet, opening the series which the letter ω closes. Hence, the expression ἐγώ εἰμί τό Α [L T Tr WH ἄλφα] καί τό Ω [Ὦ L WH], Revelation 1:8, 11 Rec., which is explained by the appended words ἡ ἀρχή καί τό τέλος, Revelation 21:6, and by the further addition ὁ πρῶτος καί ὁ ἔσχατος, Revelation 22:13. On the meaning of the phrase cf. Revelation 11:17; Isaiah 41:4; Isaiah 44:6; Isaiah 48:12; [especially B. D. American edition, p. 73].
Α, when prefixed to words as an inseparable syllable, is:
1. privative (στερητικόν), like the Latin in-, the English un-, giving a negative sense to the word to which it is prefixed, as ἀβαρής; or signifying what is contrary to it, as ἄτιμος, ἀτιμόω; before vowels generally ἀν-, as in ἀναίτιος.
2. copulative (ἀθροιστικόν), akin to the particle ἅμα [cf. Curtius, § 598], indicating community and fellowship, as in ἀδελφός, ἀκόλουθος. Hence, it is:
3. intensive (ἐπιτατικόν), strengthening the force of terms, like the Latin con in composition; as ἀτενίζω from ἀτενής [yet cf. Winers Grammar, 100 (95)]. This use, however, is doubted or denied now by many [e. g. Lob. Path. Element. i. 34f). Cf. Kühner, i. 741, § 339 Anm. 5; [Jelf, § 342 δ.]; Bttm. Gram. § 120 Anm. 11; [Donaldson, Gram., p. 334; New Crat. §§ 185, 213; Liddell and Scott, under the word].
