Greek alphabet in the context of "Mole fraction"

Greek (Modern Greek: ελληνικά, romanized: elliniká [eliniˈka] ; Ancient Greek: ἑλληνική, romanized: hellēnikḗ [helːɛːnikɛ́ː]) is an Indo-European language, constituting an independent Hellenic branch within the Indo-European language family. It is native to the territories that have had populations of Greeks since antiquity: Greece, Cyprus, Egypt, Italy (in Calabria and Salento), southern Albania, and other regions of the Balkans, Caucasus, 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.

The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting importance in the European canon. Greek is also the language in which many of the foundational texts in science and philosophy were originally composed. The New Testament of the Christian Bible was also originally written in Greek. Together with the Latin texts and traditions of the Roman world, the Greek texts and Greek societies of antiquity constitute the objects of study of the discipline of Classics.

Romanization of Greek is the transliteration (letter-mapping) or transcription (sound-mapping) of text from the Greek alphabet into the Latin alphabet.

The Greek Dark Ages (c. 1180–800 BC) was a period in Ancient Greece characterized by societal collapse of civilization, where the palaces and cities of the Mycenaeans were either destroyed, abandoned, or both.

At around the same time, the Hittite civilization in modern-day Turkey also suffered serious disruption and collapse, with cities from Troy to Gaza being destroyed. Moreover, in Egypt, the New Kingdom fell into disarray, leading to the Third Intermediate Period of Egypt. Following this mass destruction, there were fewer, smaller settlements, which suggests widespread famine and depopulation. On the Greek mainland, the Linear B script, used by Mycenaean bureaucrats to write the Greek language, ceased to be used. The later Greek alphabet did not develop until hundreds of years later, in the beginning of the Protohistoric Iron Age, c. 800 BC.

The Cyrillic script (/sɪˈrɪlɪk/ sih-RI-lik) is a writing system used for various languages across Eurasia. It is the designated national script in various Slavic, Turkic, Mongolic, Uralic, Caucasian and Iranic-speaking countries in Southeastern Europe, Eastern Europe, the Caucasus, Central Asia, North Asia, and East Asia, and used by many other minority languages.

As of 2019, around 250 million people in Eurasia use Cyrillic as the official script for their national languages, with Russia accounting for about half of them. With the accession of Bulgaria to the European Union in 2007, Cyrillic became the third official script of the European Union, following the Latin and Greek alphabets.

Ethiopian historiography includes the ancient, medieval, early modern, and modern disciplines of recording the history of Ethiopia, including both native and foreign sources. The roots of Ethiopian historical writing can be traced back to the ancient Kingdom of Aksum (c. AD 100 – c. 940). These early texts were written in either the Ethiopian Ge'ez script or the Greek alphabet, and included a variety of mediums such as manuscripts and epigraphic inscriptions on monumental stelae and obelisks documenting contemporary events. The writing of history became an established genre in Ethiopian literature during the early Solomonic dynasty (1270–1974). In this period, written histories were usually in the form of royal biographies and dynastic chronicles, supplemented by hagiographic literature and universal histories in the form of annals. Christian mythology became a linchpin of medieval Ethiopian historiography due to works such as the Orthodox Kebra Nagast. This reinforced the genealogical traditions of Ethiopia's Solomonic dynasty rulers, which asserted that they were descendants of Solomon, the legendary King of Israel.

Ethiopian historiographic literature has been traditionally dominated by Christian theology and the chronology of the Bible. There was also considerable influence from Muslim, pagan and foreign elements from within the Horn of Africa and beyond. Diplomatic ties with Christendom were established in the Roman era under Ethiopia's first Christian king, Ezana of Axum, in the 4th century AD, and were renewed in the Late Middle Ages with embassies traveling to and from medieval Europe. Building on the legacy of ancient Greek and Roman historical writings about Ethiopia, medieval European chroniclers made attempts to describe Ethiopia, its people, and religious faith in connection to the mythical Prester John, who was viewed as a potential ally against Islamic powers. Ethiopian history and its peoples were also mentioned in works of medieval Islamic historiography and even Chinese encyclopedias, travel literature, and official histories.

Linear B is a syllabic script that was used for writing in Mycenaean Greek, the earliest attested form of the Greek language. The script predates the Greek alphabet by several centuries, the earliest known examples dating to around 1450 BC. It is adapted from the earlier Linear A, an undeciphered script perhaps used for writing the Minoan language, as is the later Cypriot syllabary, which also recorded Greek. Linear B, found mainly in the palace archives at Knossos, Kydonia, Pylos, Thebes and Mycenae, disappeared with the fall of the Mycenaean civilization during the Late Bronze Age collapse. The succeeding period, known as the Greek Dark Ages, provides no evidence of the use of writing.

Linear B was deciphered in 1952 by English architect and self-taught linguist Michael Ventris based on the research of the American classicist Alice Kober. It is the only Bronze Age Aegean script to have been deciphered, with Linear A, Cypro-Minoan, and Cretan hieroglyphic remaining unreadable.

The Cypriot or Cypriote syllabary (also Classical Cypriot Syllabary) is a syllabic script used in Iron Age Cyprus, from about the 11th to the 4th centuries BCE, when it was replaced by the Greek alphabet. It has been suggested that the script remained in use as late as the 1st century BCE. A pioneer of that change was King Evagoras of Salamis. It is thought to be descended from the Cypro-Minoan syllabary, itself a variant or derivative of Linear A. Most texts using the script are in the Arcadocypriot dialect of Greek, but also one bilingual, the Amathus bilingual, a Greek and Eteocypriot, was found in Amathus.

An alphabet is a writing system that uses a standard set of symbols, called letters, to represent particular sounds in a spoken language. Specifically, letters largely correspond to phonemes as the smallest sound segments that can distinguish one word from another in a given language. Not all writing systems represent language in this way: a syllabary assigns symbols to spoken syllables, while logographies assign symbols to words, morphemes, or other semantic units.

The first letters were invented in Ancient Egypt to serve as an aid in writing Egyptian hieroglyphs; these are referred to as Egyptian uniliteral signs by lexicographers. This system was used until the 5th century AD, and fundamentally differed by adding pronunciation hints to existing hieroglyphs that had previously carried no pronunciation information. Later on, these phonemic symbols also became used to transcribe foreign words. The first fully phonemic script was the Proto-Sinaitic script, also descending from Egyptian hieroglyphs, which was later modified to create the Phoenician alphabet. The Phoenician system is considered the first true alphabet and is the ultimate ancestor of many modern scripts, including Arabic, Cyrillic, Greek, Hebrew, Latin, and possibly Brahmic.
