Greek alphabetThe Greek alphabet has been used to write the Greek language since the late 9th or early 8th century BC. It is derived from the earlier Phoenician alphabet, and was the earliest known alphabetic script to have distinct letters for vowels as well as consonants. In Archaic and early Classical times, the Greek alphabet existed in many local variants, but, by the end of the 4th century BC, the Euclidean alphabet, with 24 letters, ordered from alpha to omega, had become standard and it is this version that is still used for Greek writing today.
ThetaTheta (UKˈθiːtə, USˈθeɪtə; uppercase: Θ or ; lowercase: θ or ; thē̂ta thɛ̂ːta; Modern: thī́ta ˈθita) is the eighth letter of the Greek alphabet, derived from the Phoenician letter Teth . In the system of Greek numerals, it has a value of 9. In Ancient Greek, θ represented the aspirated voiceless dental plosive t̪h, but in Modern Greek it represents the voiceless dental fricative θ. In its archaic form, θ was written as a cross within a circle (as in the Etruscan or ), and later, as a line or point in circle ( or ).
TauTau 'tɔː,_'taʊ (uppercase Τ, lowercase τ, or ; ταυ taf) is the nineteenth letter of the Greek alphabet, representing the voiceless dental or alveolar plosive t. In the system of Greek numerals, it has a value of 300. The name in English is pronounced taʊ or tɔː, but in Greek it is taf. This is because the pronunciation of the combination of Greek letters αυ can have the pronunciation of either [ai], [av] or [af], depending on what follows and if a diaeresis is present on the second vowel (see Greek orthography).
Latin scriptThe Latin script, also known as the Roman script, is an alphabetic writing system based on the letters of the classical Latin alphabet, derived from a form of the Greek alphabet which was in use in the ancient Greek city of Cumae, in southern Italy (Magna Graecia). The Greek alphabet was adopted by the Etruscans, and subsequently their alphabet was adopted by the Romans. Several Latin-script alphabets exist, which differ in graphemes, collation and phonetic values from the classical Latin alphabet.
