Arabic script in the context of Cham language

Ancient Egyptian hieroglyphs (/ˈhaɪroʊˌɡlɪfs/ HY-roh-glifs) were the formal writing system used in Ancient Egypt for writing the Egyptian language. Hieroglyphs combined ideographic, logographic, syllabic, and alphabetic elements, with more than 1,000 distinct characters. Cursive hieroglyphs were used for religious literature on papyrus and wood. The later hieratic and demotic Egyptian scripts were derived from hieroglyphic writing, as was the Proto-Sinaitic script that later evolved into the Phoenician alphabet. Egyptian hieroglyphs are the ultimate ancestor of the Phoenician alphabet, the first widely adopted phonetic writing system. Moreover, owing in large part to the Greek and Aramaic scripts that descended from Phoenician, the majority of the world's living writing systems are descendants of Egyptian hieroglyphs—most prominently the Latin and Cyrillic scripts through Greek, and the Arabic and Brahmic scripts through Aramaic. Hieroglyphs are thought to be one of four writing systems developed without outside influence, the others being Cuneiforms, Chinese characters, and Mayan script.

The use of hieroglyphic writing arose from proto-literate symbol systems in the Early Bronze Age c. the 33rd century BC (Naqada III), with the first decipherable sentence written in the Egyptian language dating to the 28th century BC (Second Dynasty). Ancient Egyptian hieroglyphs developed into a mature writing system used for monumental inscription in the classical language of the Middle Kingdom period; during this period, the system used about 900 distinct signs. The use of this writing system continued through the New Kingdom and Late Period, and on into the Persian and Ptolemaic periods. Late survivals of hieroglyphic use are found well into the Roman period, extending into the 4th century AD.

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.

Persian, also known by its endonym Farsi or Parsi, is a Western Iranian language belonging to the Iranian branch of the Indo-Iranian subdivision of the Indo-European languages. Persian is a pluricentric language predominantly spoken and used officially within Iran, Afghanistan, and Tajikistan in three mutually intelligible standard varieties, respectively Iranian Persian (officially known as Persian), Dari Persian (officially known as Dari since 1964), and Tajiki Persian (officially known as Tajik since 1999). It is also spoken natively in the Tajik variety by a significant population within Uzbekistan, as well as within other regions with a Persianate history in the cultural sphere of Greater Iran. It is written officially within Iran and Afghanistan in the Persian alphabet, a derivative of the Arabic script, and within Tajikistan in the Tajik alphabet, a derivative of the Cyrillic script.

Modern Persian is a continuation of Middle Persian, an official language of the Sasanian Empire (224–651 CE), itself a continuation of Old Persian, which was used in the Achaemenid Empire (550–330 BCE). It originated in the region of Fars (Persia) in southwestern Iran. Its grammar is similar to that of many European languages.

Kurdish (Kurdî, کوردی, pronounced [kʊrdiː] ) is a Northwestern Iranian language or group of languages spoken by Kurds in the region of Kurdistan, namely in southeast Turkey, northern Iraq, northwest Iran, and northern Syria. It is also spoken in northeast Iran, as well as in certain areas of Armenia and Azerbaijan.

Kurdish varieties constitute a dialect continuum, with some mutually unintelligible varieties, and collectively have 26 million native speakers. The main varieties of Kurdish are Kurmanji, Sorani, and Southern Kurdish (Xwarîn). The majority of the Kurds speak Kurmanji, and most Kurdish texts are written in Kurmanji and Sorani. Kurmanji is written in the Hawar alphabet, a derivation of the Latin script, and Sorani is written in the Sorani alphabet, a derivation of the Arabic script.

Writing systems are used to record human language, and may be classified according to certain common features.

Kyrgyz is a Turkic language of the Kipchak branch spoken in Central Asia. Kyrgyz is the official language of Kyrgyzstan and a significant minority language in the Kizilsu Kyrgyz Autonomous Prefecture in Xinjiang, China and in the Gorno-Badakhshan Autonomous Region of Tajikistan. There is a very high level of mutual intelligibility between Kyrgyz, Kazakh, and Altay. A dialect of Kyrgyz known as Pamiri Kyrgyz is spoken in north-eastern Afghanistan and northern Pakistan. Kyrgyz is also spoken by many ethnic Kyrgyz through the former Soviet Union, Afghanistan, Turkey, parts of northern Pakistan, and Russia.

Kyrgyz was originally written in Göktürk script, gradually replaced by the Perso-Arabic alphabet (in use until 1928 in the USSR, still in use in China). Between 1928 and 1940, a Latin-script alphabet, the Uniform Turkic Alphabet, was used. In 1940, Soviet authorities replaced the Latin script with the Cyrillic alphabet for all Turkic languages on its territory. When Kyrgyzstan became independent following the Soviet Union's collapse in 1991, a plan to adopt the Latin alphabet became popular. Although the plan has not been implemented, it remains in occasional discussion.

Punjabi Muslims (Punjabi: پن٘جابی مُسلمان) are Punjabis who are adherents of Islam. With a population of more than 112 million, they are the third-largest predominantly Islam-adhering Muslim ethnicity in the world, after Arabs and Bengalis.

The majority of Punjabi Muslims are adherents of Sunni Islam, while a minority adhere to Shia Islam. Most of them are primarily geographically native to the Pakistani province of Punjab, but a large group of them have ancestry across the Punjab region as a whole. Punjabi Muslims speak or identify with the Punjabi language (under a Perso-Arabic script known as Shahmukhi) as their mother tongue.

In sociolinguistics, digraphia refers to the use of more than one writing system for the same language. Synchronic digraphia is the coexistence of two or more writing systems for the same language, while diachronic digraphia or sequential digraphia is the replacement of one writing system by another for a particular language.

Hindustani, with an Urdu literary standard written in Urdu alphabet and a Hindi standard written in Devanagari, is one of the "textbook examples" of synchronic digraphia, cases where writing systems are used contemporaneously. An example of diachronic digraphia, where one writing system replaces another, occurs in the case of Turkish, for which the traditional Arabic writing system was replaced with a Latin-based system in 1928.

The Berber languages, also known as the Amazigh languages or Tamazight, are a branch of the Afroasiatic language family. They comprise a group of closely related but mostly mutually unintelligible languages spoken by Berber communities, who are indigenous to North Africa. The languages are primarily spoken and not typically written. Historically, they have been written with the ancient Libyco-Berber script, which now exists in the form of Tifinagh. Today, they may also be written in the Berber Latin alphabet or the Arabic script, with Latin being the most pervasive.

The Berber languages have a level of variety similar to the Romance languages, although they are sometimes referred to as a single collective language, often as "Berber", "Tamazight", or "Amazigh". The languages, with a few exceptions, form a dialect continuum. There is a debate as to how to best sub-categorize languages within the Berber branch. Berber languages typically follow verb–subject–object word order. Their phonological inventories are diverse.

The Persian alphabet (Persian: الفبای فارسی, romanized: Alefbâ-ye Fârsi), also known as the Perso-Arabic script, is the right-to-left alphabet used for the Persian language. It is largely identical to the Arabic script with four additional letters: پ چ ژ گ (the sounds 'g', 'zh', 'ch', and 'p', respectively), in addition to the obsolete ڤ that was used for the sound /β/. This letter is no longer used in Persian, as the [β]-sound changed to [b], e.g. archaic زڤان /zaβɑn/ > زبان /zæbɒn/ 'language'. Although the sound /β/ (ڤ) is written as "و" nowadays in Farsi (Dari-Parsi/New Persian), it is different to the Arabic /w/ (و) sound, which uses the same letter.

It was the basis of many Arabic-based scripts used in Central and South Asia. It is used for both Iranian and Dari: standard varieties of Persian; and is one of two official writing systems for the Persian language, alongside the Cyrillic-based Tajik alphabet.

The Turkish alphabet (Turkish: Türk alfabesi or Türk abecesi) is a Latin-script alphabet used for writing the Turkish language, consisting of 29 letters, seven of which (Ç, Ğ, I, İ, Ö, Ş and Ü) have been modified from their Latin originals for the phonetic requirements of the language. This alphabet represents modern Turkish pronunciation with a high degree of accuracy and specificity. Mandated in 1928 as part of Atatürk's Reforms, it is the current official alphabet and the latest in a series of distinct alphabets used in different eras.

The Turkish alphabet has been the model for the official Latinization of several Turkic languages formerly written in the Arabic or Cyrillic script like Azerbaijani (1991), Turkmen (1993), and recently Kazakh (2021).

The Arabic script has numerous diacritics, which include consonant pointing known as iʻjām (إِعْجَام, IPA: [ʔiʕdʒæːm]), and supplementary diacritics known as tashkīl (تَشْكِيل, IPA: [t̪æʃkiːl]). The latter include the vowel marks termed ḥarakāt (حَرَكَات, IPA: [ħæɾækæːt̪]; sg. حَرَكَة, ḥarakah, IPA: [ħæɾækæ]).

The Arabic script is a modified abjad, where all letters are consonants, leaving it up to the reader to fill in the vowel sounds. Short consonants and long vowels are represented by letters, but short vowels and consonant length are not generally indicated in writing. Tashkīl is optional to represent missing vowels and consonant length. Modern Arabic is always written with the i‘jām—consonant pointing—but only religious texts, children's books and works for learners are written with the full tashkīl—vowel guides and consonant length. It is, however, not uncommon for authors to add diacritics to a word or letter when the grammatical case or the meaning is deemed otherwise ambiguous. In addition, classical works and historical documents rendered to the general public are often rendered with the full tashkīl, to compensate for the gap in understanding resulting from stylistic changes over the centuries.

The Arabic chat alphabet, also known as Arabizi, Arabeezi, Arabish, Franco-Arabic or simply Franco (from French: franco-arabe) refer to the romanized alphabets for informal Arabic dialects in which Arabic script is transcribed or encoded into a combination of Latin script and Western Arabic numerals. These informal chat alphabets were originally used primarily by youth in the Arab world in very informal settings—especially for communicating over the Internet or for sending messages via cellular phones—though use is not necessarily restricted by age anymore and these chat alphabets have been used in other media such as advertising.

These chat alphabets differ from more formal and academic Arabic transliteration systems, in that they use numerals and multigraphs instead of diacritics for letters such as ṭāʾ (ط) or ḍād (ض) that do not exist in the basic Latin script (ASCII), and in that what is being transcribed is an informal dialect and not Standard Arabic. These Arabic chat alphabets also differ from each other, as each is influenced by the particular phonology of the Arabic dialect being transcribed and the orthography of the dominant European language in the area—typically the language of the former colonists, and typically either French or English.

T, or t, is the twentieth letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is tee (pronounced /ˈtiː/ ), plural tees.

It is derived from the Semitic Taw 𐤕 of the Phoenician and Paleo-Hebrew script (Aramaic and Hebrew Taw ת/𐡕/, Syriac Taw ܬ, and Arabic ت Tāʼ) via the Greek letter τ (tau). In English, it is most commonly used to represent the voiceless alveolar plosive, a sound it also denotes in the International Phonetic Alphabet. It is the most commonly used consonant and the second-most commonly used letter in English-language texts.
