Alpha
Alpha (uppercase Α, lowercase α; Greek: Άλφα Álpha) is the first letter of the Greek alphabet. In the system of Greek numerals it has a value of 1. It was derived from the Phoenician letter Aleph . Letters that arose from Alpha include the Latin A and the Cyrillic letter А. In English the noun alpha is used as a synonym for "beginning", or "first" (in a series), reflecting its Greek roots.[1]

Uses
Greek
In Ancient Greek, alpha was pronounced [a] when short and [aː] when long. Where there is ambiguity, long and short alpha are sometimes written with a macron and breve today: Ᾱᾱ, Ᾰᾰ. • ὥρα = ὥρᾱ hōrā Greek pronunciation: [hɔ̌ːraː] "a time" • γλῶσσα = γλῶσσᾰ glôssa Greek pronunciation: [ɡlɔ̂ːssa] "tongue" In Modern Greek, vowel length has been lost, and all instances of alpha represent the short Greek pronunciation: [a]. In the polytonic orthography of Greek, alpha, like other vowel letters, can occur with several diacritic marks: any of three accent symbols (ά, ὰ, ᾶ), and either of two breathing marks (ἁ, ἀ), as well as combinations of these. It can also combine with the iota subscript (ᾳ). Greek grammar In the Attic-Ionic dialect of Ancient Greek, long alpha [aː] fronted to [ɛː] (eta). In Ionic, the shift took place in all positions. In Attic, the shift did not take place after epsilon, iota, and rho (ε, ι, ρ; e, i, r). In Doric and Aeolic, long alpha is preserved in all positions.[2] • Doric, Aeolic, Attic χώρᾱ chṓrā — Ionic χώρη chṓrē, "country" • Doric, Aeolic φᾱ́μᾱ phā́mā — Attic, Ionic φήμη phḗmē, "report" Privative a is the Ancient Greek prefix ἀ- or ἀν- a-, an-, added to words to negate them. It originates from the Proto-Indo-European *n̥- (syllabic nasal) and is cognate with English un-. Copulative a is the Greek prefix ἁ- or ἀ- ha-, a-. It comes from Proto-Indo-European *sm̥.

Math and science
