IMFI is an acronym for "Initial, Medial, Final, Isolated", a writing system in which each character has four different potential shapes:
The Arabic, Mandaic, Mongolian, N'Ko, Pahlavi and Syriac scripts are examples of IMFI writing systems.
The Arabic alphabet, or the Arabic abjad, is the Arabic script as specifically codified for writing the Arabic language. It is written from right-to-left in a cursive style, and includes 28 letters, of which most have contextual letterforms. Unlike the Latin alphabet, the script has no concept of letter case. The Arabic alphabet is considered an abjad, with only consonants required to be written; due to its optional use of diacritics to notate vowels, it is considered an impure abjad.
Camel case is the practice of writing phrases without spaces or punctuation and with capitalized words. The format indicates the first word starting with either case, then the following words having an initial uppercase letter. Common examples include YouTube, PowerPoint, HarperCollins, FedEx, iPhone, eBay, and LaGuardia. Camel case is often used as a naming convention in computer programming. It is also sometimes used in online usernames such as JohnSmith, and to make multi-word domain names more legible, for example in promoting EasyWidgetCompany.com. In fact, WikiWikiWeb, an ancestor of Wikipedia, is written in camel case.
A syllable is a basic unit of organization within a sequence of speech sounds, such as within a word, typically defined by linguists as a nucleus with optional sounds before or after that nucleus. In phonology and studies of languages, syllables are often considered the "building blocks" of words. They can influence the rhythm of a language, its prosody, its poetic metre and its stress patterns. Speech can usually be divided up into a whole number of syllables: for example, the word ignite is made of two syllables: ig and nite.
The Burmese alphabet is an abugida used for writing Burmese. It is ultimately adapted from a Brahmic script, either the Kadamba or Pallava alphabet of South India. The Burmese alphabet is also used for the liturgical languages of Pali and Sanskrit. In recent decades, other, related alphabets, such as Shan and modern Mon, have been restructured according to the standard of the Burmese alphabet
The Arabic script has numerous diacritics, which include consonant pointing known as iʻjām (إِعْجَام), and supplementary diacritics known as tashkīl (تَشْكِيل). The latter include the vowel marks termed ḥarakāt.
Historical Chinese phonology deals with reconstructing the sounds of Chinese from the past. As Chinese is written with logographic characters, not alphabetic or syllabary, the methods employed in Historical Chinese phonology differ considerably from those employed in, for example, Indo-European linguistics; reconstruction is more difficult because, unlike Indo-European languages, no phonetic spellings were used.
The zero-width non-joiner is a non-printing character used in the computerization of writing systems that make use of ligatures. For example, in writing systems that feature initial, medial and final letter-forms, such as the Persian alphabet, when a ZWNJ is placed between two characters that would otherwise be joined into a ligature, it instead prevents the ligature and causes them to be printed in their final and initial forms, respectively. This is also an effect of a space character, but a ZWNJ is used when it is desirable to keep the characters closer together or to connect a word with its morpheme.
Khmer script is an abugida (alphasyllabary) script used to write the Khmer language, the official language of Cambodia. It is also used to write Pali in the Buddhist liturgy of Cambodia and Thailand.
The Persian alphabet, also known as the Perso-Arabic script, is the right-to-left alphabet used for the Persian language. It is a variation of the Arabic script with five additional letters: پ چ ژ گ, in addition to the obsolete ڤ that was used for the sound. This letter is no longer used in Persian, as the -sound changed to, e.g. archaic زڤان > زبان 'language'.
The writing system of the Korean language is a syllabic alphabet of character parts organized into character blocks representing syllables. The character parts cannot be written from left to right on the computer, as in many Western languages. Every possible syllable in Korean would have to be rendered as syllable blocks by a font, or each character part would have to be encoded separately. Unicode has both options; the character parts ㅎ (h) and ㅏ (a), and the combined syllable 하 (ha), are encoded.
He is the fifth letter of the Semitic abjads, including Arabic hāʾه, Aramaic hē 𐡄, Hebrew hēה, Phoenician hē 𐤄, and Syriac hē ܗ. Its sound value is the voiceless glottal fricative.
General Chinese is a diaphonemic orthography invented by Yuen Ren Chao to represent the pronunciations of all major varieties of Chinese simultaneously. It is "the most complete genuine Chinese diasystem yet published". It can also be used for the Korean, Japanese, and Vietnamese pronunciations of Chinese characters, and challenges the claim that Chinese characters are required for interdialectal communication in written Chinese.
The Myanmar Language Commission Transcription System (1980), also known as the MLC Transcription System (MLCTS), is a transliteration system for rendering Burmese in the Latin alphabet. It is loosely based on the common system for romanization of Pali, has some similarities to the ALA-LC romanization and was devised by the Myanmar Language Commission. The system is used in many linguistic publications regarding Burmese and is used in MLC publications as the primary form of romanization of Burmese.
Iran System encoding is an 8-bit character encoding scheme and was created by Iran System corporation for Persian language support. This encoding was in use in Iran in DOS-based programs. After the introduction of Microsoft code page 1256, this encoding became obsolete. However, some Windows and DOS programs using this encoding are still in use and some Windows fonts with this encoding exist. Now most programs use code page 1256 or Unicode.
Rasm is an Arabic writing script often used in the early centuries of Classical Arabic literature. Essentially it is the same as today's Arabic script except for the big difference that the Arabic diacritics are omitted. These diacritics include i'jam, consonant pointing, and tashkil, supplementary diacritics. The latter include the ḥarakāt (حَرَكَات) short vowel marks—singular: ḥarakah (حَرَكَة). As an example, in rasm, the two distinct letters ص ض are indistinguishable because all the dots are omitted. Rasm is also known as Arabic skeleton script.
The Lepcha script, or Róng script, is an abugida used by the Lepcha people to write the Lepcha language. Unusually for an abugida, syllable-final consonants are written as diacritics.
The traditional Mongolian script, also known as the Hudum Mongol bichig, was the first writing system created specifically for the Mongolian language, and was the most widespread until the introduction of Cyrillic in 1946. It is traditionally written in vertical lines Top-Down, right across the page. Derived from the Old Uyghur alphabet, it is a true alphabet, with separate letters for consonants and vowels. It has been adapted for such languages as Oirat and Manchu. Alphabets based on this classical vertical script continue to be used in Mongolia and Inner Mongolia to write Mongolian, Xibe and, experimentally, Evenki.
The hamza is an Arabic script character that, in the Arabic alphabet, denotes a glottal stop and, in non-Arabic languages, indicates a diphthong, vowel, or other features, depending on the language. Derived from the letter ʿAyn, the hamza is written in initial, medial and final positions as an unlinked letter or placed above or under a carrier character. Despite its common usage as a letter in Modern Standard Arabic, it is generally not considered to be one of its letters, although some argue that it should be considered a letter.
Scholars have attempted to reconstruct the phonology of Old Chinese from documentary evidence. Although the writing system does not describe sounds directly, shared phonetic components of the most ancient Chinese characters are believed to link words that were pronounced similarly at that time. The oldest surviving Chinese verse, in the Classic of Poetry (Shijing), shows which words rhymed in that period. Scholars have compared these bodies of contemporary evidence with the much later Middle Chinese reading pronunciations listed in the Qieyun rhyme dictionary published in 601 AD, though this falls short of a phonemic analysis. Supplementary evidence has been drawn from cognates in other Sino-Tibetan languages and in Min Chinese, which split off before the Middle Chinese period, Chinese transcriptions of foreign names, and early borrowings from and by neighbouring languages such as Hmong–Mien, Tai and Tocharian languages.
Although Old Chinese is known from written records beginning around 1200 BC, the logographic script provides much more indirect and partial information about the pronunciation of the language than alphabetic systems used elsewhere. Several authors have produced reconstructions of Old Chinese phonology, beginning with the Swedish sinologist Bernhard Karlgren in the 1940s and continuing to the present day. The method introduced by Karlgren is unique, comparing categories implied by ancient rhyming practice and the structure of Chinese characters with descriptions in medieval rhyme dictionaries, though more recent approaches have also incorporated other kinds of evidence.
