Rough breathing

In the polytonic orthography of Ancient Greek, the rough breathing (dasỳ pneûma or δασεῖα daseîa; spīritus asper) character is a diacritical mark used to indicate the presence of an h sound before a vowel, diphthong, or after rho. It remained in the polytonic orthography even after the Hellenistic period, when the sound disappeared from the Greek language. In the monotonic orthography of Modern Greek phonology, in use since 1982, it is not used at all. The absence of an /h/ sound is marked by the smooth breathing. The character, or those with similar shape such as , have also been used for a similar sound by Thomas Wade (and others) in the Wade–Giles system of romanization for Mandarin Chinese. Herbert Giles and others have used a left (opening) curved single quotation mark for the same purpose; the apostrophe, backtick, and visually similar characters are often seen as well. The rough breathing comes from the left-hand half of the letter H. In some archaic Greek alphabets, the letter was used for h (Heta), and this usage survives in the Latin letter H. In other dialects, it was used for the vowel ɛː (Eta), and this usage survives in the modern system of writing Ancient Greek, and in Modern Greek. The rough breathing ( ̔ ) is placed over an initial vowel, or over the second vowel of an initial diphthong. αἵρεσις haíresis 'choice' (→ Latin haeresis → English heresy) ἥρως hḗrōs 'hero' An upsilon or rho at the beginning of a word always takes a rough breathing. ὕμνος hýmnos 'hymn' ῥυθμός rhythmós 'rhythm' In some writing conventions, the rough breathing is written on the second of two rhos in the middle of a word. This is transliterated as rrh in Latin. διάῤῥοια diárrhoia 'diarrhoea' In crasis (contraction of two words), when the second word has a rough breathing, the contracted vowel does not take a rough breathing. Instead, the consonant before the contracted vowel changes to the aspirated equivalent (i.e., π → φ, τ → θ, κ → χ), if possible, and the contracted vowel takes the apostrophe or coronis (identical to the smooth breathing).

Greek alphabet

The 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.

Greek diacritics

Greek orthography has used a variety of diacritics starting in the Hellenistic period. The more complex polytonic orthography (πολυτονικό σύστημα γραφής), which includes five diacritics, notates Ancient Greek phonology. The simpler monotonic orthography (μονοτονικό σύστημα γραφής), introduced in 1982, corresponds to Modern Greek phonology, and requires only two diacritics. Polytonic orthography () is the standard system for Ancient Greek and Medieval Greek.

Modern Greek

Modern Greek (Νέα Ελληνικά, Néa Elliniká, ˈne.a eliniˈka or Κοινή Νεοελληνική Γλώσσα, Kiní Neoellinikí Glóssa), generally referred to by speakers simply as Greek (Ελληνικά, Elliniká), refers collectively to the dialects of the Greek language spoken in the modern era, including the official standardized form of the languages sometimes referred to as Standard Modern Greek.
