Greek (ελληνική γλώσσα IPA: [eliniˈki ˈɣlosa] or simply ελληνικά IPA: [eliniˈka] — "Hellenic") has a documented history of 3,500 years, the longest of any single natural language in the Indo-European language family. It is also one of the earliest attested Indo-European languages, with fragmentary records in Mycenaean dating back to the 15th or 14th century BC, making it the world's oldest recorded living language. Today, it is spoken by approximately 15–25 million people in Greece (official), Cyprus (official), Albania, Bulgaria, the Former Yugoslav Republic of Macedonia (FYROM), Italy, Turkey, Armenia, Georgia, Ukraine, Moldova, Romania, Russia, Egypt, Jordan and emigrant communities around the world, including Australia, United States, Canada, Germany and elsewhere.
Greek has been written in the Greek alphabet (the first to introduce vowels) since the 9th century BC in Greece (before that in Linear B), and the 4th century BC in Cyprus (before that in Cypriot syllabary). Greek literature has a continuous history of nearly three thousand years.
Greek has been written in the Greek alphabet since approximately the 9th century BC. In classical Greek, as in classical Latin, only upper-case letters existed. The lower-case Greek letters were developed much later by medieval scribes to permit a faster, more convenient cursive writing style with the use of ink and quill. The variant of the alphabet in use today is essentially the late Ionic variant, introduced for writing classical Attic in 403 BC.
The modern Greek alphabet consists of 24 letters, each with a capital (majuscule) and lowercase (minuscule) form. The letter sigma has an additional lowercase form (ς) used in final position.
Majuscule form
Α Β Γ Δ Ε Ζ Η Θ Ι Κ Λ Μ Ν Ξ Ο Π Ρ Σ Τ Υ Φ Χ Ψ Ω
Minuscule form
α β γ δ ε ζ η θ ι κ λ μ ν ξ ο π ρ σ τ υ φ χ ψ ω
In addition to the letters, the Greek alphabet also features a number of diacritical signs: three different accent marks (acute, grave and circumflex), originally denoting different shapes of pitch accent on the stressed vowel; the so-called breathing marks (spiritus asper and spiritus lenis), originally used to signal presence or absence of word-initial /h/; and the diaeresis, used to mark full syllabic value of a vowel that would otherwise be read as part of a diphthong. These marks were introduced during the course of the Hellenistic period. Actual usage of the grave in handwriting had seen a rapid decline in favor of uniform usage of the acute during the late 20th century, and it had only been retained in typography.
In the writing reform of 1982, the use of most of them was abolished from official use in Greece. Since then, Modern Greek has been written mostly in the simplified monotonic orthography, which employs only the acute accent and the diaeresis. The traditional system, now called the polytonic orthography, is still in use for Modern Greek in book printing and in the usage of some writers in general, and it is used internationally for the writing of Ancient Greek.
