There are several romanisation schemes for the Malayalam script, including ITRANS and ISO 15919.
Typesetting Malayalam on computers became an issue with their spread in the late 20th century. The lack of diacritics on keyboards led to the adoption of ASCII only romanisation schemes. ASCII only schemes remain popular in email correspondence and input methods because of their ease of entry. These schemes are also called Manglish. The disadvantage of ASCII schemes is that letter case is meaningful, so that transliterated names may not be capitalised.
The Mozhi system of transliteration [1] is an unofficial system used to transliterate Malayalam, it can also be used for Tamil. This system does not need the use of diacritics. Even though it has more elaborate scheme, Mozhi [2] is as follows:
aa i ii u uu R RR e E ai o O au Ll Lll am aH k kh g gh ng ch chh j jh nj T Th D Dh N th thh d dh n p ph b bh m y r l v S sh s h L zh rr t
ITRANS is an ASCII scheme which does not use diacritics for transliteration to Latin script.
The "National Library at Kolkata romanisation" is one of the most widely used transliteration schemes in dictionaries and grammars of Indo-Aryan languages and Dravidian languages including Malayalam. This transliteration scheme is also known as '(American) Library of Congress' scheme and is nearly identical to one of the possible ISO 15919 variants. The scheme is an extension of the IAST scheme that is used for transliteration of Sanskrit.
ISO 15919 "Transliteration of Devanagari and related Indic scripts into Latin characters" is one of a series of international standards for romanisation. It was published in 2001 and uses diacritics to map the much larger set of consonants and vowels in Brahmic scripts to the Latin script.
Devanagari is an Indic script used in the northern Indian subcontinent. Also simply called Nāgari, it is a left-to-right abugida, based on the ancient Brāhmi script. It is one of the official scripts of the Republic of India and Nepal. It was developed and in regular use by the 7th century CE and achieved its modern form by 1000 CE. The Devanāgari script, composed of 48 primary characters, including 14 vowels and 34 consonants, is the fourth most widely adopted writing system in the world, being used for over 120 languages.
The Kannada script is an abugida of the Brahmic family, used to write Kannada, one of the Dravidian languages of South India especially in the state of Karnataka. It is one of the official scripts of the Indian Republic. Kannada script is also widely used for writing Sanskrit texts in Karnataka. Several minor languages, such as Tulu, Konkani, Kodava, Sanketi and Beary, also use alphabets based on the Kannada script. The Kannada and Telugu scripts share very high mutual intellegibility with each other, and are often considered to be regional variants of single script. Other scripts similar to Kannada script are Sinhala script, and Old Peguan script (used in Burma).
Malayalam script is a Brahmic script used commonly to write Malayalam, which is the principal language of Kerala, India, spoken by 45 million people in the world. It is a Dravidian language spoken in the Indian state of Kerala and the union territories of Lakshadweep and Puducherry by the Malayali people. It is one of the official scripts of the Indian Republic. Malayalam script is also widely used for writing Sanskrit texts in Kerala.
In linguistics, romanization or romanisation is the conversion of text from a different writing system to the Roman (Latin) script, or a system for doing so. Methods of romanization include transliteration, for representing written text, and transcription, for representing the spoken word, and combinations of both. Transcription methods can be subdivided into phonemic transcription, which records the phonemes or units of semantic meaning in speech, and more strict phonetic transcription, which records speech sounds with precision.
Devanagari is an Indic script used for many Indo-Aryan languages of North India and Nepal, including Hindi, Marathi and Nepali, which was the script used to write Classical Sanskrit. There are several somewhat similar methods of transliteration from Devanagari to the Roman script, including the influential and lossless IAST notation. Romanized Devanagari is also called Romanagari.
The National Library at Kolkata romanisation is a widely used transliteration scheme in dictionaries and grammars of Indic languages. This transliteration scheme is also known as (American) Library of Congress and is nearly identical to one of the possible ISO 15919 variants. The scheme is an extension of the IAST scheme that is used for transliteration of Sanskrit.
When used as a diacritic mark, the term dot refers to the glyphs "combining dot above", and "combining dot below" which may be combined with some letters of the extended Latin alphabets in use in a variety of languages. Similar marks are used with other scripts.
The International Alphabet of Sanskrit Transliteration (IAST) is a transliteration scheme that allows the lossless romanisation of Indic scripts as employed by Sanskrit and related Indic languages. It is based on a scheme that emerged during the 19th century from suggestions by Charles Trevelyan, William Jones, Monier Monier-Williams and other scholars, and formalised by the Transliteration Committee of the Geneva Oriental Congress, in September 1894. IAST makes it possible for the reader to read the Indic text unambiguously, exactly as if it were in the original Indic script. It is this faithfulness to the original scripts that accounts for its continuing popularity amongst scholars.
The Harvard-Kyoto Convention is a system for transliterating Sanskrit and other languages that use the Devanāgarī script into ASCII. It is predominantly used informally in e-mail, and for electronic texts.
ISO 15919 is one of a series of international standards for romanization by the International Organization for Standardization. It was published in 2001 and uses diacritics to map the much larger set of consonants and vowels in Brahmic and Nastaliq scripts to the Latin script.
The "Indian languages TRANSliteration" (ITRANS) is an ASCII transliteration scheme for Indic scripts, particularly for the Devanagari script.
The romanization of Arabic is the systematic rendering of written and spoken Arabic in the Latin script. Romanized Arabic is used for various purposes, among them transcription of names and titles, cataloging Arabic language works, language education when used instead of or alongside the Arabic script, and representation of the language in scientific publications by linguists. These formal systems, which often make use of diacritics and non-standard Latin characters and are used in academic settings or for the benefit of non-speakers, contrast with informal means of written communication used by speakers such as the Latin-based Arabic chat alphabet.
The Uddin and Begum Hindustani Romanization scheme is an international standard for romanising Urdu and Hindi. Syed Fasih Uddin and Quader Unissa Begum presented the scheme in 1992, at the First International Urdu Conference in Chicago.
The Latin script, also known as the Roman script, is an alphabetic writing system based on the letters of the classical Latin alphabet, derived from a form of the Greek alphabet which was in use in the ancient Greek city of Cumae, in southern Italy. The Greek alphabet was altered by the Etruscans, and subsequently their alphabet was altered by the Romans. Several Latin-script alphabets exist, which differ in graphemes, collation and phonetic values from the classical Latin alphabet.
Romanisation of Bengali is the representation of written Bengali language in the Latin script. Various romanisation systems for Bengali are used, most of which do not perfectly represent Bengali pronunciation. While different standards for romanisation have been proposed for Bengali, none has been adopted with the same degree of uniformity as Japanese or Sanskrit.
There are various systems of romanization of the Armenian alphabet.
The Mozhi is a popular romanization scheme for Malayalam script. It is primarily used for Input Method Editors for Malayalam and loosely based on ITrans scheme for Devanagari.
There are several systems for romanization of the Telugu script.
The Sanskrit Library Phonetic basic encoding scheme (SLP1) is an ASCII transliteration scheme for the Sanskrit language from and to the Devanagari script.
The Velthuis system of transliteration is an ASCII transliteration scheme for the Sanskrit language from and to the Devanagari script. It was developed in about 1983 by Frans Velthuis, a scholar living in Groningen, Netherlands, who created a popular, high-quality software package in LaTeX for typesetting Devanāgarī. The primary documentation for the scheme is the system's clearly-written software manual. It is based on using the ISO 646 repertoire to represent mnemonically the accents used in standard scholarly transliteration. It does not use diacritics as IAST does. It may optionally use capital letters in a manner similar but not identical to the Harvard-Kyoto or ITRANS schemes.manual para 4.1
