Latin alphabet in the context of Input method

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

The history of writing traces the development of writing systems and how their use transformed and was transformed by different societies. The use of writing – as well as the resulting phenomena of literacy and literary culture in some historical instances – has had myriad social and psychological consequences.

Each historical invention of writing emerged from systems of proto-writing that used ideographic and mnemonic symbols but were not capable of fully recording spoken language. True writing, where the content of linguistic utterances can be accurately reconstructed by later readers, is a later development. As proto-writing is not capable of fully reflecting the grammar and lexicon used in languages, it is often only capable of encoding broad or imprecise information.

Arabic is a Central Semitic language of the Afroasiatic language family spoken primarily in the Arab world. The International Organization for Standardization (ISO) assigns language codes to 32 varieties of Arabic, including its standard form of Literary Arabic, known as Modern Standard Arabic, which is derived from Classical Arabic. This distinction exists primarily among Western linguists; Arabic speakers themselves generally do not distinguish between Modern Standard Arabic and Classical Arabic, but rather refer to both as al-ʿarabiyyatu l-fuṣḥā (اَلعَرَبِيَّةُ ٱلْفُصْحَىٰ "the eloquent Arabic") or simply al-fuṣḥā (اَلْفُصْحَىٰ).

Arabic is the third most widespread official language after English and French, one of six official languages of the United Nations, and the liturgical language of Islam. Arabic is widely taught in schools and universities around the world and is used to varying degrees in workplaces, governments and the media. During the Middle Ages, Arabic was a major vehicle of culture and learning, especially in science, mathematics and philosophy. As a result, many European languages have borrowed words from it. Arabic influence, mainly in vocabulary, is seen in European languages (mainly Spanish and to a lesser extent Portuguese, Catalan, and Sicilian) owing to the proximity of Europe and the long-lasting Arabic cultural and linguistic presence, mainly in Southern Iberia, during the Al-Andalus era. Maltese is a Semitic language developed from a dialect of Arabic and written in the Latin alphabet. The Balkan languages, including Albanian, Greek, Serbo-Croatian, and Bulgarian, have also acquired many words of Arabic origin, mainly through direct contact with Ottoman Turkish.

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.

Maya script, also known as Maya glyphs, is historically the native writing system of the Maya civilization of Mesoamerica and is the only Mesoamerican writing system that has been substantially deciphered. The earliest inscriptions found which are identifiably Maya date to the 3rd century BCE in San Bartolo, Guatemala. Maya writing was in continuous use throughout Mesoamerica until the Spanish conquest of the Maya in the 16th and 17th centuries. Though modern Mayan languages are almost entirely written using the Latin alphabet rather than Maya script, there have been recent developments encouraging a revival of the Maya glyph system.

Maya writing used logograms complemented with a set of syllabic glyphs, somewhat similar in function to modern Japanese writing. Maya writing was called "hieroglyphics" or hieroglyphs by early European explorers of the 18th and 19th centuries who found its general appearance reminiscent of Egyptian hieroglyphs, although the two systems are unrelated.

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.

There are six official languages used in United Nations (UN) meetings and in which the UN writes and publishes all its official documents. In 1946, five languages were chosen as official languages of the UN: English, French, Russian, Spanish, and Chinese. In 1973, Arabic was voted to be an additional official language. As of 2025, the official languages of the United Nations are:

• English (British English with Oxford spelling), in Latin alphabet;
• French (Metropolitan French – français métropolitain / langues d'oïl) in Latin alphabet;
• Spanish (Peninsular Spanish – español peninsular / castellano) in Spanish alphabet;
• Russian (Moscow Russian – московское произношение moskovskoye proiznosheniye) in the Russian Cyrillic alphabet;
• Chinese (Standard Mandarin – 中文 zhōngwén / 普通话 pǔtōnghuà) in Simplified Chinese characters;
• Arabic (Modern Standard Arabic – العربية al-ʿarabiyyah / الفصحى al-fuṣḥá) in Naskh / Arabic abjad.

According to the UN Charter each of these six languages is equally authoritative although English and French have traditionally received preferential status and are the only two official and working languages of the UN Secretariat. It is an unspoken rule that the UN Secretary General and other high ranking United Nations officials must be fluent (at least C1 – Advanced fluency level according to the Common European Framework of Reference for Languages / CEFRL) in at least English and French. The UN has struggled to provide parity of all 6 languages as the English language has become the dominant world language in the digital age.

Polish (endonym: język polski, [ˈjɛ̃zɨk ˈpɔlskʲi] , polszczyzna [pɔlˈʂt͡ʂɨzna] or simply polski, [ˈpɔlskʲi] ) is a West Slavic language of the Lechitic subgroup, within the Indo-European language family, and is written in the Latin script. It is primarily spoken in Poland and serves as the official language of the country, as well as the language of the Polish diaspora around the world. In 2024, there were over 39.7 million Polish native speakers. It ranks as the sixth-most-spoken among languages of the European Union. Polish is subdivided into regional dialects. It maintains strict T–V distinction pronouns, honorifics, and various forms of formalities when addressing individuals.

The traditional 32-letter Polish alphabet has nine additions (ą, ć, ę, ł, ń, ó, ś, ź, ż) to the letters of the basic 26-letter Latin alphabet, while removing three (x, q, v). Those three letters are at times included in an extended 35-letter alphabet. The traditional set comprises 23 consonants and nine written vowels, including two nasal vowels (ę, ą) denoted by a reversed diacritic hook called an ogonek. Polish is a synthetic and fusional language which has seven grammatical cases. It has fixed penultimate stress and an abundance of palatal consonants. Contemporary Polish developed in the 1700s as the successor to the medieval Old Polish (10th–16th centuries) and Middle Polish (16th–18th centuries).

The romanization of Macedonian is the transliteration of text in Macedonian from the Macedonian Cyrillic alphabet into the Latin alphabet. Romanization can be used for various purposes, such as rendering of proper names in foreign contexts, or for informal writing of Macedonian in environments where Cyrillic is not easily available. Official use of romanization by North Macedonia's authorities is found, for instance, on road signage and in passports. Several different codified standards of transliteration currently exist and there is widespread variability in practice.

Although used for transliteration, Macedonian Latin script is neither widespread nor used in any formal or semi-formal communication in Macedonia. The language law of Macedonia emphasizes Cyrillic as the only alphabet of Macedonian language.

The West Slavs are Slavic peoples who speak the West Slavic languages. They separated from the common Slavic group around the 7th century, and established independent polities in Central Europe by the 8th to 9th centuries. The West Slavic languages diversified into their historically attested forms over the 10th to 14th centuries.

Today, groups which speak West Slavic languages include the Poles, Czechs, Slovaks, Silesians, Kashubians, and Sorbs. From the ninth century onwards, most West Slavs converted to Roman Catholicism, thus coming under the cultural influence of the Latin Church, adopting the Latin alphabet, and tending to be more closely integrated into cultural and intellectual developments in western Europe than the East Slavs, who converted to Eastern Orthodox Christianity and adopted the Cyrillic alphabet.

Romanization of Bulgarian is the practice of transliteration of text in Bulgarian from its conventional Cyrillic orthography into the Latin alphabet. Romanization can be used for various purposes, such as rendering of proper names and place names in foreign-language contexts, or for informal writing of Bulgarian in environments where Cyrillic is not easily available. Official use of romanization by Bulgarian authorities is found, for instance, in identity documents and in road signage. Several different standards of transliteration exist, one of which was chosen and made mandatory for common use by the Bulgarian authorities in a law of 2009.

The romanization of Ukrainian, or Latinization of Ukrainian, is the representation of the Ukrainian language in Latin letters. Ukrainian is written in its own Ukrainian alphabet, which is based on the Cyrillic script. Romanization may be employed to represent Ukrainian text or pronunciation for non-Ukrainian readers, on computer systems that cannot reproduce Cyrillic characters, or for typists who are not familiar with the Ukrainian keyboard layout. Methods of romanization include transliteration (representing written text) and transcription (representing the spoken word).

In contrast to romanization, there have been several historical proposals for a Ukrainian Latin alphabet, usually based on those used by West Slavic languages, but none have been widely accepted.

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.

A, or a, is the first letter and the first vowel letter of the Latin alphabet, used in the modern English alphabet, and others worldwide. Its name in English is a (pronounced /ˈeɪ/ AY), plural aes.

It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version is often written in one of two forms: the double-storey |a| and single-storey |ɑ|. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type.

D, or d, is the fourth 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 dee (pronounced /ˈdiː/ ), plural dees.
