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.
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).
PhiPhi (faɪ; uppercase Φ, lowercase φ or φ; φεῖ pheî phéî̯; Modern Greek: φι fi fi) is the twenty-first letter of the Greek alphabet. In Archaic and Classical Greek (c. 9th century BC to 4th century BC), it represented an aspirated voiceless bilabial plosive ([ph]), which was the origin of its usual romanization as . During the later part of Classical Antiquity, in Koine Greek (c. 4th century BC to 4th century AD), its pronunciation shifted to that of a voiceless bilabial fricative ([ɸ]), and by the Byzantine Greek period (c.
Chi (letter)Chi 'kaɪ,_"xi: (uppercase Χ, lowercase χ; χῖ) is the twenty-second letter of the Greek alphabet. Its value in Ancient Greek was an aspirated velar stop /kh/ (in the Western Greek alphabet: /ks/). In Koine Greek and later dialects it became a fricative ([x]/[ç]) along with Θ and Φ. In Modern Greek, it has two distinct pronunciations: In front of high or front vowels (/e/ or /i/) it is pronounced as a voiceless palatal fricative [ç], as in German ich or like the h in some pronunciations of the English words hew and human.
ZetaZeta (UK'ziːtə, US'zeɪtə; uppercase Ζ, lowercase ζ; ζῆτα, ζήτα, classical d͡zɛ̌:ta or zdɛ̌:ta zē̂ta; ˈzita zíta) is the sixth letter of the Greek alphabet. In the system of Greek numerals, it has a value of 7. It was derived from the Phoenician letter zayin . Letters that arose from zeta include the Roman Z and Cyrillic З. Unlike the other Greek letters, this letter did not take its name from the Phoenician letter from which it was derived; it was given a new name on the pattern of beta, eta and theta.
RadianThe radian, denoted by the symbol rad, is the unit of angle in the International System of Units (SI) and is the standard unit of angular measure used in many areas of mathematics. It is defined such that one radian is the angle subtended at the centre of a circle by an arc that is equal in length to the radius. The unit was formerly an SI supplementary unit and is currently a dimensionless SI derived unit, defined in the SI as 1 rad = 1 and expressed in terms of the SI base unit metre (m) as .
Romanization of GreekRomanization of Greek is the transliteration (letter-mapping) and/or transcription (sound-mapping) of text from the Greek alphabet into the Latin alphabet. The conventions for writing and romanizing Ancient Greek and Modern Greek differ markedly. The sound of the English letter B (/b/) was written as β in ancient Greek but is now written as the digraph μπ, while the modern β sounds like the English letter V (/v/) instead.
Phoenician alphabetThe Phoenician alphabet is an alphabet (more specifically, an abjad) known in modern times from the Canaanite and Aramaic inscriptions found across the Mediterranean region. The name comes from the Phoenician civilization. The Phoenician alphabet is also called the Early Linear script (in a Semitic context, not connected to Minoan writing systems), because it is an early development of the Proto- or Old Canaanite or Proto-Sinaitic script, into a linear, purely alphabetic script, also marking the transfer from a multi-directional writing system, where a variety of writing directions occurred, to a regulated horizontal, right-to-left script.
Greek languageGreek (Elliniká, eliniˈka; Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, Italy (in Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary.
