The classical twenty-four-letter alphabet that is now used to represent the Greek language was originally the local alphabet of Ionia. Epichoric alphabets are commonly divided into four major types according to their different treatments of additional consonant letters for the aspirated consonants (/pʰ, kʰ/) and consonant clusters (/ks, ps/) of Greek. Individual letter shapes were mirrored depending on the writing direction of the current line.
In handwriting, ensure the lowercase α has a clear loop and tail to distinguish it from the Latin a. For the range A0–FF (hex), it follows the Unicode range 370–3CF (see below) except that some symbols, like ©, ½, § etc. are used where Unicode has unused locations. Some letters can occur in variant shapes, mostly inherited from medieval minuscule handwriting. The Roman alphabet has a similar extended form with such double-digit letters when necessary, but it is used for columns in a table or chart rather than chapters of an organization. In an organization that expands to more than 24 chapters, the chapter after Ω chapter is AA chapter, followed by AB chapter, etc.
- To mark a letter as a numeral sign, a small stroke called keraia is added to the right of it.
- Here too, the changes in the pronunciation of the letter names between Ancient and Modern Greek are regular.
- Each of these is still a "chapter Letter", albeit a double-digit letter just as 10 through 99 are double-digit numbers.
- During the Renaissance, western printers adopted the minuscule letter forms as lowercase printed typefaces, while modeling uppercase letters on the ancient inscriptional forms.
Like Latin and other alphabetic scripts, Greek originally had only a single form of each letter, without a distinction between uppercase and lowercase. Some dialects of the Aegean and Cypriot have retained long consonants and pronounce ˈɣamːa and ˈkapʰa; also, ήτα has come to be pronounced ˈitʰa in Cypriot. The letter ⟨ε⟩ was called e psilon ("plain e") to distinguish it from the identically pronounced digraph ⟨αι⟩, while, similarly, ⟨υ⟩, which at this time was pronounced y, was called y psilon ("plain y") to distinguish it from the identically pronounced digraph ⟨οι⟩. Thus, the letters ⟨ο⟩ and ⟨ω⟩, pronounced identically by this time, were called o mikron ("small o") and o mega ("big o").
By the 9th century, Byzantine scribes had begun to employ the lowercase form, which they derived from the cursive styles of the uppercase letters. Throughout antiquity, Greek had only a single uppercase form of each letter. Yes, you can use alpha in academic writing, scientific notation, and mathematical expressions. Both are acceptable, but the single-story form is more common in mathematical and scientific contexts. Therefore, Alpha, both as a symbol and term, is used to refer to the "first", or "primary", or "principal" (most significant) occurrence or status of a thing.
International Phonetic Alphabet
Sometimes early fraternal organizations were known by their Greek letter names because the mottos that these names stood for were secret and revealed only to members of the fraternity. The name of this fraternal organization is an acronym for the ancient Greek phrase Φιλοσοφία Βίου Κυβερνήτης (Philosophia Biou Kybernētēs), which means "Love of wisdom, the guide of life" and serves as the organization's motto. In North America, many college fraternities and sororities are named with combinations of Greek letters, and are hence also known as "Greek letter organizations". To mark a letter as a numeral sign, a small stroke called keraia is added to the right of it.
Among consonant letters, all letters that denoted voiced plosive consonants (/b, d, g/) and aspirated plosives (/pʰ, tʰ, kʰ/) in Ancient Greek stand for corresponding fricative sounds in Modern Greek. For a number of letters, sound values differ considerably between Ancient and Modern Greek, because their pronunciation has followed a set of systematic phonological shifts that affected the language in its post-classical stages. In both Ancient and Modern Greek, the letters of the Greek alphabet have fairly stable and consistent symbol-to-sound mappings, making pronunciation of καλαμακησ ορθοπεδικοσ words largely predictable.
This iota represents the former offglide of what were originally long diphthongs, ⟨ᾱι, ηι, ωι⟩ (i.e. /aːi, ɛːi, ɔːi/), which became monophthongized during antiquity. The acute accent in aulós avˈlos ('flute') distinguishes the word from its homograph áulos ˈailos ('immaterial'). Modern Greek speakers typically use the same, modern symbol–sound mappings in reading Greek of all historical stages. As a consequence, the spellings of words in Modern Greek are often not predictable from the pronunciation alone, while the reverse mapping, from spelling to pronunciation, is usually regular and predictable. Additionally, Modern and Ancient Greek now use different diacritics, with ancient Greek using the polytonic orthography and modern Greek keeping only the stress accent (acute) and the diaeresis. Sound values and conventional transcriptions for some of the letters differ between Ancient and Modern Greek usage because the pronunciation of Greek has changed significantly between the 5th century BC and the present.

For a time, a writing style with alternating right-to-left and left-to-right lines (called boustrophedon, literally 'ox-turning', after the manner of an ox ploughing a field) was common, until in the classical period the left-to-right writing direction became the norm. When it was adopted for writing Greek, certain consonants were adapted in order to express vowels. The vowel letters ⟨α, η, ω⟩ carry an additional diacritic in certain words, the so-called iota subscript, which has the shape of a small vertical stroke or a miniature ⟨ι⟩ below the letter. Apart from its use in writing the Greek language, in both its ancient and its modern forms, the Greek alphabet today also serves as a source of international technical symbols and labels in many domains of mathematics, science, and other fields. The two forms are the "single-story" α (used in handwriting and most fonts) and the "double-story" ɑ (used in some typographic contexts).
As an organization expands, it establishes a B chapter, a Γ chapter, and so on and so forth. The IPA symbol for the palatal lateral approximant is ⟨ʎ⟩, which looks similar to lambda, but is actually an inverted lowercase y. Several of them denote fricative consonants; the rest stand for variants of vowel sounds. Several Greek letters are used as phonetic symbols in the International Phonetic Alphabet (IPA). Many symbols have traditional uses, such as lower case epsilon (ε) for an arbitrarily small positive number, lower case pi (π) for the ratio of the circumference of a circle to its diameter, capital sigma (Σ) for summation, and lower case sigma (σ) for standard deviation. Greek symbols are used as symbols in mathematics, physics and other sciences.
The uppercase letter alpha is not generally used as a symbol because it tends to be rendered identically to the uppercase Latin A. Most occurrences of alpha in science are the lowercase alpha. In aerodynamics, the letter is used as a symbol for the angle of attack of an aircraft and the word "alpha" is used as a synonym for this property. In Attic, the shift did not take place after epsilon, iota, and rho (ε, ι, ρ; e, i, r). In Ancient Greek, alpha was pronounced a and could be either phonemically long (aː) or short (a). Alpha /ˈælfə/ ⓘ ALF-ə (uppercase Α, lowercase α)a is the first letter of the Greek alphabet.
