Devanagari (देवनागरी,, ) is an Indic script used in the Indian subcontinent. Also simply called Nāgari, it is a left-to-right abugida (a type of segmental writing system), 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 8th 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 orthography of this script reflects the pronunciation of the language. Unlike the Latin alphabet, the script has no concept of letter case. It is written from left to right, has a strong preference for symmetrical rounded shapes within squared outlines, and is recognisable by a horizontal line, known as a शिरोरेखा, that runs along the top of full letters. In a cursory look, the Devanāgarī script appears different from other Indic scripts, such as Bengali-Assamese or Gurmukhi, but a closer examination reveals they are very similar except for angles and structural emphasis. Among the languages using it as a primary or secondary script are Marathi, Pāḷi, Sanskrit, Hindi, Boro, Nepali, Sherpa, Prakrit, Apabhramsha, Awadhi, Bhojpuri, Braj Bhasha, Chhattisgarhi, Haryanvi, Magahi, Nagpuri, Rajasthani, Khandeshi, Bhili, Dogri, Kashmiri, Maithili, Konkani, Sindhi, Nepal Bhasa, Mundari, Angika, Bajjika and Santali. The Devanāgarī script is closely related to the Nandināgarī script commonly found in numerous ancient manuscripts of South India, and it is distantly related to a number of southeast Asian scripts.

Etymology

is formed by the addition of the word (देव) to the word (नागरी). is an adjective derived from (नगर), a Sanskrit word meaning "town" or "city," and literally means "urban" or "urbane". The word (implicitly modifying, "script") was used on its own to refer to a North Indian script, or perhaps a number of such scripts, as Al-Biruni attests in the 11th century; the form is attested later, at least by the 18th century. The name of the Nandināgarī script is also formed by adding a prefix to the generic script name. The precise origin and significance of the prefix remains unclear.

History

Devanāgarī is part of the Brahmic family of scripts of India, Nepal, Tibet, and Southeast Asia. It is a descendant of the 3rd century BCE Brāhmī script, which evolved into the Nagari script which in turn gave birth to Devanāgarī and Nandināgarī. Devanāgarī has been widely adopted across India and Nepal to write Sanskrit, Marathi, Hindi, Central Indo-Aryan languages, Konkani, Boro, and various Nepalese languages. Some of the earliest epigraphic evidence attesting to the developing Sanskrit Nāgarī script in ancient India is from the 1st to 4th century CE inscriptions discovered in Gujarat. Variants of script called, recognisably close to Devanāgarī, are first attested from the 1st century CE Rudradaman inscriptions in Sanskrit, while the modern standardised form of Devanāgarī was in use by about 1000 CE. Medieval inscriptions suggest widespread diffusion of Nāgarī-related scripts, with biscripts presenting local script along with the adoption of Nāgarī scripts. For example, the mid 8th-century Pattadakal pillar in Karnataka has text in both Siddha Matrika script, and an early Telugu-Kannada script; while, the Kangra Jawalamukhi inscription in Himachal Pradesh is written in both Sharada and Devanāgarī scripts. The Nāgarī script was in regular use by the 7th century CE, and it was fully developed by about the end of first millennium. The use of Sanskrit in Nāgarī script in medieval India is attested by numerous pillar and cave-temple inscriptions, including the 11th-century Udayagiri inscriptions in Madhya Pradesh, and an inscribed brick found in Uttar Pradesh, dated to be from 1217 CE, which is now held at the British Museum. The script's prototypes and related versions have been discovered with ancient relics outside India, in places such as Sri Lanka, Myanmar and Indonesia. In East Asia, the script (considered as the closest precursor to Nāgarī) was in use by Buddhists. Nāgarī has been the primus inter pares of the Indic scripts. It has long been used traditionally by religiously educated people in South Asia to record and transmit information, existing throughout the land in parallel with a wide variety of local scripts (such as Moḍī, Kaithi, and Mahajani) used for administration, commerce, and other daily uses. Sharada remained in parallel use in Kashmir. An early version of Devanāgarī is visible in the Kutila inscription of Bareilly dated to VS 1049 (992 CE), which demonstrates the emergence of the horizontal bar to group letters belonging to a word. One of the oldest surviving Sanskrit texts from the early post-Maurya period consists of 1,413 Nāgarī pages of a commentary by Patanjali, with a composition date of about 150 BCE, the surviving copy transcribed about 14th century CE.

East Asia

In the 7th century, under the rule of Songtsen Gampo of the Tibetan Empire, Thonmi Sambhota was sent to Nepal to open marriage negotiations with a Nepali princess and to find a writing system suitable for the Tibetan language. He then invented the Tibetan script based on the Nāgarī used in Kashmir. He added 6 new characters for sounds that did not exist in Sanskrit. Other scripts closely related to Nāgarī (such as Siddhaṃ) were introduced throughout East and Southeast Asia from the 7th to the 10th centuries CE: notably in Indonesia, Vietnam, and Japan. Most of the Southeast Asian scripts have roots in Dravidian scripts, but a few found in south-central regions of Java and isolated parts of southeast Asia resemble Devanāgarī or its prototypes. The Kawi script in particular is similar to the Devanāgarī in many respects, though the morphology of the script has local changes. The earliest inscriptions in the Devanāgarī-like scripts are from around the 10th century CE, with many more between the 11th and 14th centuries. Some of the old-Devanāgarī inscriptions are found in Hindu temples of Java, such as the Prambanan temple. The Ligor and the Kalasan inscriptions of central Java, dated to the 8th century, are also in the Nāgarī script of north India. According to the epigraphist and Asian Studies scholar Lawrence Briggs, these may be related to the 9th century copper plate inscription of Devapaladeva (Bengal) which is also in early Devanāgarī script. The term kawi in Kawi script is a loan word from (poetry). According to anthropologists and Asian studies scholars John Norman Miksic and Goh Geok Yian, the 8th century version of early Nāgarī or Devanāgarī script was adopted in Java, Bali, and Khmer around the 8th–9th centuries, as evidenced by the many contemporaneous inscriptions of this period.

Letters

The letter order of Devanāgarī, like nearly all Brāhmic scripts, is based on phonetic principles that consider both the manner and place of articulation of the consonants and vowels they represent. This arrangement is usually referred to as the ("garland of letters"). The format of Devanāgarī for Sanskrit serves as the prototype for its application, with minor variations or additions, to other languages.

Vowels

The vowels and their arrangement are:

Consonants

The table below shows the consonant letters (in combination with inherent vowel ) and their arrangement. To the right of the Devanāgarī letter it shows the Latin script transliteration using International Alphabet of Sanskrit Transliteration, and the phonetic value (IPA) in Hindi.

Vowel diacritics

The table below shows consonants with common vowel diacritics and their ISO 15919 transliteration. Vowels in their independent form on the top and in their corresponding dependent form (vowel sign) combined with the consonant '' on the bottom. is without any added vowel sign, where the vowel is inherent. A vowel combines with a consonant in their diacritic form. For example, the vowel आ combines with the consonant क् to form the syllabic letter का, with halant (cancel sign) removed and added vowel sign which is indicated by diacritics. The vowel अ combines with the consonant क् to form क with halant removed. But the diacritic series of क, ख, ग, घ (, respectively) is without any added vowel sign, as the vowel अ is inherent. The combinations of all Sanskrit consonants and vowels, each in alphabetical order, are laid out in the or table. In the following table, the IAST transliteration of each combination will appear on mouseover:

Old forms

The following letter variants are also in use, particularly in older texts and in specific regions:

Conjunct consonants

As mentioned, successive consonants lacking a vowel in between them may physically join as a conjunct consonant or ligature. When Devanāgarī is used for writing languages other than Sanskrit, conjuncts are used mostly with Sanskrit words and loan words. Native words typically use the basic consonant and native speakers know to suppress the vowel when it is conventional to do so. For example, the native Hindi word is written करना. The government of these clusters ranges from widely to narrowly applicable rules, with special exceptions within. While standardised for the most part, there are certain variations in clustering, of which the Unicode used on this page is just one scheme. The following are a number of rules:

Accent marks

The pitch accent of Vedic Sanskrit is written with various symbols depending on shakha. In the Rigveda, is written with a bar below the line (◌॒), with a stroke above the line (◌॑) while is unmarked.

Punctuation

The end of a sentence or half-verse may be marked with the "।" symbol (called a, meaning "bar", or called a , meaning "full stop/pause"). The end of a full verse may be marked with a double-, a "॥" symbol. A comma (called an , meaning "short stop/pause") is used to denote a natural pause in speech. Punctuation marks of Western origin, such as the colon, semicolon, exclamation mark, dash, and question mark have been in use in Devanāgarī script since at least the 1900s, matching their use in European languages.

Fonts

A variety of Unicode fonts are in use for Devanāgarī. These include Akshar, Annapurna, Arial, CDAC-Gist Surekh, CDAC-Gist Yogesh, Chandas, Gargi, Gurumaa, Jaipur, Jana, Kalimati, Kanjirowa, Lohit Devanagari, Mangal, Kokila, ,Preeti, Raghu, Sanskrit2003, Santipur OT, Siddhanta, and Thyaka. The form of Devanāgarī fonts vary with function. According to Harvard College for Sanskrit studies: "Uttara [companion to Chandas] is the best in terms of ligatures but, because it is designed for Vedic as well, requires so much vertical space that it is not well suited for the 'user interface font' (though an excellent choice for the 'original field' font). Santipur OT is a beautiful font reflecting a very early [medieval era] typesetting style for Devanagari. Sanskrit 2003 is a good all-around font and has more ligatures than most fonts, though students will probably find the spacing of the CDAC-Gist Surekh font makes for quicker comprehension and reading." The Google Fonts project has a number of Unicode fonts for Devanāgarī in a variety of typefaces in serif, sans-serif, display and handwriting categories.

Numerals

Transliteration

There are several methods of Romanisation or transliteration from Devanāgarī to the Roman script.

Hunterian system

The Hunterian system is the national system of romanisation in India, officially adopted by the Government of India.

ISO 15919

A standard transliteration convention was codified in the ISO 15919 standard of 2001. It uses diacritics to map the much larger set of Brāhmic graphemes to the Latin script. The Devanāgarī-specific portion is nearly identical to the academic standard for Sanskrit, IAST.

IAST

The International Alphabet of Sanskrit Transliteration (IAST) is the academic standard for the romanisation of Sanskrit. IAST is the de facto standard used in printed publications, like books, magazines, and electronic texts with Unicode fonts. It is based on a standard established by the Congress of Orientalists at Athens in 1912. The ISO 15919 standard of 2001 codified the transliteration convention to include an expanded standard for sister scripts of Devanāgarī. The National Library at Kolkata romanisation, intended for the romanisation of all Indic scripts, is an extension of IAST.

Harvard-Kyoto

Compared to IAST, Harvard-Kyoto looks much simpler. It does not contain all the diacritic marks that IAST contains. It was designed to simplify the task of putting large amount of Sanskrit textual material into machine readable form, and the inventors stated that it reduces the effort needed in transliteration of Sanskrit texts on the keyboard. This makes typing in Harvard-Kyoto much easier than IAST. Harvard-Kyoto uses capital letters that can be difficult to read in the middle of words.

ITRANS

ITRANS is a lossless transliteration scheme of Devanāgarī into ASCII that is widely used on Usenet. It is an extension of the Harvard-Kyoto scheme. In ITRANS, the word is written "devanaagarii" or "devanAgarI". ITRANS is associated with an application of the same name that enables typesetting in Indic scripts. The user inputs in Roman letters and the ITRANS pre-processor translates the Roman letters into Devanāgarī (or other Indic languages). The latest version of ITRANS is version 5.30 released in July 2001. It is similar to Velthuis system and was created by Avinash Chopde to help print various Indic scripts with personal computers.

Velthuis

The disadvantage of the above ASCII schemes is case-sensitivity, implying that transliterated names may not be capitalised. This difficulty is avoided with the system developed in 1996 by Frans Velthuis for TeX, loosely based on IAST, in which case is irrelevant.

ALA-LC Romanisation

ALA-LC romanisation is a transliteration scheme approved by the Library of Congress and the American Library Association, and widely used in North American libraries. Transliteration tables are based on languages, so there is a table for Hindi, one for Sanskrit and Prakrit, etc.

WX

WX is a Roman transliteration scheme for Indian languages, widely used among the natural language processing community in India. It originated at IIT Kanpur for computational processing of Indian languages. The salient features of this transliteration scheme are as follows.

Encodings

ISCII

ISCII is an 8-bit encoding. The lower 128 codepoints are plain ASCII, the upper 128 codepoints are ISCII-specific. It has been designed for representing not only Devanāgarī but also various other Indic scripts as well as a Latin-based script with diacritic marks used for transliteration of the Indic scripts. ISCII has largely been superseded by Unicode, which has, however, attempted to preserve the ISCII layout for its Indic language blocks.

Unicode

The Unicode Standard defines four blocks for Devanāgarī: Devanagari (U+0900–U+097F), Devanagari Extended (U+A8E0–U+A8FF), Devanagari Extended-A (U+11B00–11B5F), and Vedic Extensions (U+1CD0–U+1CFF).

Devanāgari keyboard layouts

InScript layout

InScript is the standard keyboard layout for Devanāgarī as standardized by the Government of India. It is inbuilt in all modern major operating systems. Microsoft Windows supports the InScript layout, which can be used to input unicode Devanāgarī characters. InScript is also available in some touchscreen mobile phones.

Typewriter

This layout was used on manual typewriters when computers were not available or were uncommon. For backward compatibility some typing tools like Indic IME still provide this layout.

Phonetic

Such tools work on phonetic transliteration. The user writes in the Latin alphabet and the IME automatically converts it into Devanāgarī. Some popular phonetic typing tools are Akruti, Baraha IME and Google IME. The Mac OS X operating system includes two different keyboard layouts for Devanāgarī: one resembles the INSCRIPT/KDE Linux, while the other is a phonetic layout called "Devanāgarī QWERTY". Any one of the Unicode fonts input systems is fine for the Indic language Wikipedia and other wikiprojects, including Hindi, Bhojpuri, Marathi, and Nepali Wikipedia. While some people use InScript, the majority uses either Google phonetic transliteration or the input facility Universal Language Selector provided on Wikipedia. On Indic language wikiprojects, the phonetic facility provided initially was java-based, and was later supported by Narayam extension for phonetic input facility. Currently Indic language Wiki projects are supported by Universal Language Selector (ULS), that offers both phonetic keyboard (Aksharantaran, Marathi: अक्षरांतरण, Hindi: लिप्यंतरण, बोलनागरी) and InScript keyboard (Marathi: मराठी लिपी). The Ubuntu Linux operating system supports several keyboard layouts for Devanāgarī, including Harvard-Kyoto, WX notation, Bolanagari and phonetic. The 'remington' typing method in Ubuntu IBUS is similar to the Krutidev typing method, popular in Rajasthan. The 'itrans' method is useful for those who know English (and the English keyboard) well but are not familiar with typing in Devanāgarī.
