A form of western Greek native to Euboea, which among other things had Χ for /ks/, was transplanted to Italy by early Greek colonists, and became the ancestor of the Old Italic alphabets and ultimately, through Etruscan, of the Latin alphabet.
Athens used a local form of the alphabet until the 5th century BC; it lacked the letters Ξ and Ψ as well as the vowel symbols Η and Ω.
Like Latin and Cyrillic, Greek originally had only a single form of each letter; it developed the letter case distinction between upper-case and lower-case forms in parallel with Latin during the modern era.
Sound values and conventional transcriptions for some of the letters differ between Ancient Greek and Modern Greek usage, because the pronunciation of Greek has changed significantly between the 5th century BC and today. The traditional orthography, which is used for Ancient Greek and sometimes for Modern Greek, has many diacritics, such as accent marks for pitch accent ("polytonic"), the breathing marks for the presence and absence of the initial In both Ancient and Modern Greek, the letters of the Greek alphabet have fairly stable and consistent symbol-to-sound mappings, making pronunciation of words largely predictable.
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 technical symbols and labels in many domains of mathematics, science and other fields.
There were initially numerous local variants of the Greek alphabet, which differed in the use and non-use of the additional vowel and consonant symbols and several other features.In Phoenician, each letter name was a word that began with the sound represented by that letter; thus ʾaleph, the word for "ox", was used as the name for the glottal stop sound, and so on.When the letters were adopted by the Greeks, most of the Phoenician names were maintained or modified slightly to fit Greek phonology; thus, ʾaleph, bet, gimel became alpha, beta, gamma.In other countries, students of Ancient Greek may use a variety of conventional approximations of the historical sound system in pronouncing Ancient Greek.Several letter combinations have special conventional sound values different from those of their single components.
