Abjad in the context of "Shahmukhi"

A writing system comprises a set of symbols, called a script, as well as the rules by which the script represents a particular language. The earliest writing appeared during the late 4th millennium BC. Throughout history, each independently invented writing system gradually emerged from a system of proto-writing, where a small number of ideographs were used in a manner incapable of fully encoding language, and thus lacking the ability to express a broad range of ideas.

Writing systems are generally classified according to how their symbols, called graphemes, relate to units of language. Phonetic writing systems – which include alphabets and syllabaries – use graphemes that correspond to sounds in the corresponding spoken language. Alphabets use graphemes called letters that generally correspond to spoken phonemes. They are typically divided into three sub-types: Pure alphabets use letters to represent both consonant and vowel sounds, abjads generally only use letters representing consonant sounds, and abugidas use letters representing consonant–vowel pairs. Syllabaries use graphemes called syllabograms that represent entire syllables or moras. By contrast, logographic (or morphographic) writing systems use graphemes that represent the units of meaning in a language, such as its words or morphemes. Alphabets typically use fewer than 100 distinct symbols, while syllabaries and logographies may use hundreds or thousands, respectively.

The Arabic alphabet, or the Arabic abjad, is the Arabic script as specifically codified for writing the Arabic language. It is a unicameral script written from right-to-left in a cursive style, and includes 28 letters, of which most have contextual forms. Unlike the modern Latin alphabet, the script has no concept of letter case. The Arabic alphabet is an abjad, with only consonants required to be written (though the long vowels – ā ī ū – are also written, with letters used for consonants); due to its optional use of diacritics to notate vowels, it is considered an impure abjad.

An abugida (/ˌɑːbuːˈɡiːdə, ˌæb-/ ; from Geʽez: አቡጊዳ, 'äbugīda)—sometimes also called an alphasyllabary, neosyllabary, or pseudo-alphabet—is a segmental writing system in which consonant–vowel sequences are written as units; each unit is based on a consonant letter, and vowel notation is secondary, like a diacritical mark. This contrasts with a full alphabet, in which vowels have status equal to consonants, and with an abjad, in which vowel marking is absent, partial, or optional. In less formal contexts, all three types of script may be termed "alphabets". The terms also contrast them with a syllabary, in which a single symbol denotes the combination of a consonant and a vowel.

Related concepts were introduced independently in 1948 by James Germain Février (using the term néosyllabisme) and David Diringer (using the term semisyllabary), and in 1959 by Fred Householder (introducing the term pseudo-alphabet). The Ethiopic term "abugida" was chosen as a designation for the concept in 1990 by Peter T. Daniels. Faber suggested "segmentally coded syllabically linear phonographic script"; William O. Bright used the term alphasyllabary; and Gnanadesikan and Rimzhim, Katz, & Fowler suggested aksara or āksharik.

The Albanian Vilayet (Ottoman Turkish: ولايت ارناود, Vilâyet-i Arnavid) was a projected vilayet of the Ottoman Empire in the western Balkan Peninsula, which was to include the four Ottoman vilayets with substantial ethnic Albanian populations: Kosovo Vilayet, Scutari Vilayet, Manastir Vilayet, and Janina Vilayet. In some proposals, it included the Salonica Vilayet as well. The creation of the Vilayet was confirmed in September 1912, but negotiations were interrupted a month later in October by the beginning of the First Balkan War. Plans for an Albanian Vilayet were lost with the Partition of Albania.

A separate Albanian vilayet was a part of the agenda of many Albanian organizations and societies since 1877, during the period known as the Albanian National Awakening. Establishment of such a vilayet was agreed between the Albanian rebels and the authorized representatives of the Ottoman government on 4 September 1912, following the Albanian Revolt of 1912. Soon after that agreement however, the First Balkan War broke out and most of the remaining European territory of the Ottoman Empire was occupied by the Balkan League member states. After the army of the Kingdom of Serbia captured Skopje, Ismail Qemali invited a group of Albanians from all four Ottoman vilayets that were agreed to be united into the Albanian Vilayet, to attend an All-Albanian Congress in Valona. There they declared independence on 28 November 1912, and set up the Provisional Government of Albania.

Geʽez (/ˈɡiːɛz/ GEE-ez; Ge'ez: ግዕዝ, romanized: Gəʽəz, IPA: [ˈɡɨʕɨz] ) is an abugida used to write several Afro-Asiatic and Nilo-Saharan languages of Ethiopia and Eritrea. It originated as an abjad (consonantal alphabet) and was first used to write the Geʽez language, now the liturgical language of the Ethiopian Orthodox Tewahedo Church, the Eritrean Orthodox Tewahedo Church, the Eritrean Catholic Church, the Ethiopian Catholic Church, and Haymanot Judaism of the Beta Israel Jewish community in Ethiopia. In the languages Amharic and Tigrinya, the script is often called fidäl (ፊደል), meaning "script" or "letter". Under the Unicode Standard and ISO 15924, it is defined as Ge'ez text.

The Geʽez script has been adapted to write other languages, mostly Ethiopian and Eritrean Semitic, particularly Amharic in Ethiopia, and Tigrinya in both Eritrea and Ethiopia. It has also been used to write Sebat Bet and other Gurage languages and at least 20 other languages of Ethiopia. In Eritrea it has traditionally been used for Tigre and just recently for Bilen. The Geʽez script has also recently been used to write Anuak, and used in limited extent to write some other Nilo-Saharan Nilotic languages, including Majang languages. It was also used in the past to write some Omotic languages, including Wolaytta, Bench, Hamer, and Kafa.For the representation of sounds, this article uses a system that is common (though not universal) among linguists who work on Ethiopian Semitic languages. This differs somewhat from the conventions of the International Phonetic Alphabet. See the articles on the individual languages for information on the pronunciation.

The Phoenician alphabet is an abjad (consonantal alphabet) used across the Mediterranean civilization of Phoenicia for most of the 1st millennium BC. It was one of the first alphabets, attested in Canaanite and Aramaic inscriptions found across the Mediterranean basin. In the history of writing systems, the Phoenician script also marked the first to have a fixed writing direction—while previous systems were multi-directional, Phoenician was written horizontally, from right to left. It developed directly from the Proto-Sinaitic script used during the Late Bronze Age, which was derived in turn from Egyptian hieroglyphs.

The Phoenician alphabet was used to write Canaanite languages spoken during the Early Iron Age, sub-categorized by historians as Phoenician, Hebrew, Moabite, Ammonite and Edomite, as well as Old Aramaic. It was widely disseminated outside of the Canaanite sphere by Phoenician merchants across the Mediterranean, where it was adopted and adapted by other cultures. The Phoenician alphabet proper was used in Ancient Carthage until the 2nd century BC, where it was used to write the Punic language. Its direct descendant scripts include the Aramaic and Samaritan alphabets, several Alphabets of Asia Minor, and the Archaic Greek alphabets.

The Hebrew language uses the Hebrew alphabet with optional vowel diacritics. The Romanization of Hebrew refers specifically to the use of the Latin alphabet to represent Hebrew words.For example, the Hebrew name יִשְׂרָאֵל ('Israel') can be Romanized as Yisrael or Yiśrāʼēl in addition to Israel.

Particularly in contexts where the Latin alphabet is the dominant writing system, Romanization and transliteration are often used interchangeably. The actual relationship between the two terms is dependent on the discipline and/or context. However, generally speaking, one can safely define transliteration as the representation of words from one script in a different script. Romanization is a subset of transliteration, specifically referring to the representation of non-Latin or vernacular scripts in the Latin writing system. Transliteration and Romanization can—but do not necessarily—account for vowels even for abjads as Hebrew.

The Hebrew alphabet (Hebrew: אָלֶף־בֵּית עִבְרִי, Alefbet ivri), known variously by scholars as the Ktav Ashuri, Jewish script, square script and block script, is a unicameral abjad script used in the writing of the Hebrew language. Alphabets based on the Hebrew script are used to write other Jewish languages, most notably Yiddish, Ladino, Judeo-Arabic, and Judeo-Persian. In modern Hebrew, vowels are increasingly introduced. Hebrew script is used informally in Israel to write Levantine Arabic, especially among Druze. The script is an offshoot of the Imperial Aramaic alphabet, which flourished during the Achaemenid Empire, and which itself derives from the Phoenician alphabet.

Historically, a different abjad script was used to write Hebrew: the original, old Hebrew script, now known as the Paleo-Hebrew alphabet, has been largely preserved in a variant form as the Samaritan alphabet, and is still used by the Samaritans. The present Jewish script or square script, on the contrary, is a stylized form of the Aramaic alphabet and was technically known by Jewish sages as Ashurit (lit. 'Assyrian script'), since its origins were known to be from Assyria (Mesopotamia).

The Ugaritic alphabet is an abjad (consonantal alphabet) with syllabic elements written using the same tools as cuneiform (i.e. pressing a wedge-shaped stylus into a clay tablet), which emerged c. 1400 or 1300 BCE to write Ugaritic, an extinct Northwest Semitic language; it fell out of use amid the Late Bronze Age collapse c. 1190 BCE. It was discovered in Ugarit (modern Ras Shamra, Syria) in 1928. It has 30 letters. Other languages, particularly Hurrian, were occasionally written in the Ugaritic script in the area around Ugarit, but not elsewhere.

Clay tablets written in Ugaritic provide the earliest evidence of both the North Semitic and South Semitic orders of the alphabet, which gave rise to the alphabetic orders of the reduced Phoenician writing system and its descendants, including the Paleo-Hebrew alphabet, Hebrew, Syriac, Greek and Latin, and of the Geʽez script, which was also influenced by the ancient Egyptian hieroglyphic writing system, and adapted for Amharic. The Arabic and Ancient South Arabian scripts are the only other Semitic alphabets which have letters for all or almost all of the 29 commonly reconstructed Proto-Semitic consonant phonemes.
