Origin

The Gujarati script () was adapted from the

script was in wide use. The earliest known document in the Old Gujarati script is a handwritten manuscript ''Adi Parva'' dating from 1591–92, and the script first appeared in print in a 1797 advertisement. The third phase is the use of script developed for ease and fast writing. The use of ''shirorekhā'' (the topline as in Devanagari) was abandoned. Until the 19th century it was used mainly for writing letters and keeping accounts, while the Devanagari script was used for literature and academic writings. It is also known as the ''śarāphī'' (banker's), ''vāṇiāśāī'' (merchant's) or ''mahājanī'' (trader's) script. This script became the basis of the modern script. Later the same script was adopted by writers of manuscripts.

Overview

The Gujarati writing system is an
abugida An abugida (, from Ge'ez: ), sometimes known as alphasyllabary, neosyllabary or pseudo-alphabet, is a segmental writing system in which consonant-vowel sequences are written as units; each unit is based on a consonant letter, and vowel n ...
, in which each base consonantal character possesses an inherent vowel, that vowel being ''a'' For postconsonantal vowels other than ''a'', the consonant is applied with
diacritic A diacritic (also diacritical mark, diacritical point, diacritical sign, or accent) is a glyph added to a letter or to a basic glyph. The term derives from the Ancient Greek (, "distinguishing"), from (, "to distinguish"). The word ''diacriti ...
s, while for non-postconsonantal vowels (initial and post-vocalic positions), there are full-formed characters. With ''a'' being the most frequent vowel, this is a convenient system in the sense that it cuts down on the width of writing. Following out of the aforementioned property, consonants lacking a proceeding vowel may condense into the proceeding consonant, forming ''compound'' or ''conjunct'' letters. The formation of these conjuncts follows a system of rules depending on the consonants involved. In accordance with all the other Indic scripts, Gujarati is written from left to right, and is not case-sensitive. The Gujarati script is basically
phonemic In phonology and linguistics, a phoneme () is a unit of sound that can distinguish one word from another in a particular language. For example, in most dialects of English, with the notable exception of the West Midlands and the north-west ...
, with a few exceptions. First out of these is the written representation of non-pronounced ''a''s, which are of three types. *Word-final ''a''s. Thus ઘર "house" is pronounced ''ghar'' and not ''ghara''. The ''a''s remain unpronounced before
postposition Prepositions and postpositions, together called adpositions (or broadly, in traditional grammar, simply prepositions), are a class of words used to express spatial or temporal relations (''in'', ''under'', ''towards'', ''before'') or mark various ...
s and before other words in compounds: ઘરપર "in the house" is ''gharpar'' and not ''gharapar''; ઘરકામ "housework" is ''gharkām'' and not ''gharakām''. This non-pronunciation is not always the case with conjunct characters: મિત્ર "friend" is truly ''mitra''. *Naturally
elided In linguistics, an elision or deletion is the omission of one or more sounds (such as a vowel, a consonant, or a whole syllable) in a word or phrase. However, these terms are also used to refer more narrowly to cases where two words are run toget ...
''a''s through the combination of morphemes. The root પકડ઼ ''pakaṛ'' "hold" when inflected as પકડ઼ે "holds" remains written as ''pakaṛe'' even though pronounced as ''pakṛe''. ''See Gujarati phonology#ə-deletion''. *''a''s whose non-pronunciation follows the above rule, but which are in single words not resultant of any actual combination. Thus વરસાદ "rain", written as ''varasād'' but pronounced as ''varsād''. Secondly and most importantly, being of Sanskrit-based Devanagari, Gujarati's script retains notations for the obsolete (short ''i, u'' vs. long ''ī, ū''; ''r̥'', ''ru''; ''ś'', ''ṣ''), and lacks notations for innovations ( vs. ; vs. ; clear vs. murmured vowels). Contemporary Gujarati uses English punctuation, such as the

, comma, and full stop. Apostrophes are used for the rarely written clitic. Quotation marks are not as often used for direct quotes. The full stop replaced the traditional vertical bar, and the colon, mostly obsolete in its Sanskritic capacity (see below), follows the European usage.


Use for Avestan

The Zoroastrians of India, who represent one of the largest surviving Zoroastrian communities worldwide, would transcribe Avestan in Nagri script-based scripts as well as the
Avestan alphabet The Avestan alphabet (Middle Persian: transliteration: ''dyn' dpywryh'', transcription: ''dēn dēbīrē'', fa, دین دبیره, translit=din dabire) is a writing system developed during Iran's Sasanian era (226–651 CE) to render ...
. This is a relatively recent development first seen in the ca. 12th century texts of Neryosang Dhaval and other Parsi Sanskritist theologians of that era, and which are roughly contemporary with the oldest surviving manuscripts in Avestan script. Today, Avestan is most commonly typeset in Gujarati script ( Gujarati being the traditional language of the Indian Zoroastrians). Some Avestan letters with no corresponding symbol are synthesized with additional diacritical marks, for example, the /z/ in ''zaraθuštra'' is written with /j/ + dot below.

Vowels

Vowels A vowel is a syllabic speech sound pronounced without any stricture in the vocal tract. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness and also in quantity (len ...
(''svara''), in their conventional order, are historically grouped into "short" (''hrasva'') and "long" (''dīrgha'') classes, based on the "light" (''laghu'') and "heavy" (''guru'') syllables they create in traditional verse. The historical long vowels ''ī'' and ''ū'' are no longer distinctively long in pronunciation. Only in verse do syllables containing them assume the values required by meter. Finally, a practice of using inverted ''mātra''s to represent English and 's has gained ground. ર ''r'', જ ''j'' and હ ''h'' form the irregular forms of રૂ ''rū'', જી ''jī'' and હૃ ''hṛ''.


Consonants

Consonants (''vyañjana'') are grouped in accordance with the traditional, linguistically based

The letter ર ''ra'' is an exception; it is called રેફ ''reph''. * Starting with ક ''ka'' and ending with જ્ઞ ''jña'', the order goes: :Plosives & Nasals (left to right, top to bottom) → Sonorants & Sibilants (top to bottom, left to right) → Bottom box (top to bottom) *The final two are compound characters that happen to be traditionally included in the set. They are indiscriminate as to their original constituents, and they are the same size as a single consonant character. * Written (V)''h''V sets in speech result in murmured V̤(C) sets (''see Gujarati phonology#Murmur''). Thus (with ''ǐ'' = ''i'' or ''ī'', and ''ǔ'' = ''u'' or ''ū''): ''ha'' → from ; ''hā'' → from ; ''ahe'' → from ; ''aho'' → from ; ''ahā'' → from ; ''ahǐ'' → from ; ''ahǔ'' → from ; ''āhǐ'' → from ; ''āhǔ'' → from ; etc.


Non-vowel diacritics


Digits


Conjuncts

As mentioned, successive consonants lacking a vowel in between them may physically join together as a 'conjunct'. The government of these clusters ranges from widely to narrowly applicable rules, with special exceptions within. While standardized for the most part, there are certain variations in clustering, of which the Unicode used on this page is just one scheme. The rules: *23 out of the 36 consonants contain a vertical right stroke (ખ, ધ, ળ etc.). As first or middle fragments/members of a cluster, they lose that stroke. e.g. ત + વ = ત્વ, ણ + ઢ = ણ્ઢ, થ + થ = થ્થ. **શ ''ś(a)'' appears as a different, simple ribbon-shaped fragment preceding વ ''va'', ન ''na'', ચ ''ca'' and ર ''ra''. Thus શ્વ ''śva'', શ્ન ''śna'', શ્ચ ''śca'' and શ્ર ''śra''. In the first three cases the second member appears to be squished down to accommodate શ's ribbon fragment. In શ્ચ ''śca'' we see ચ's

equivalent of च as the squished-down second member. See the note on ર to understand the formation of શ્ર ''śra''. *ર ''r(a)'' **as a first member it takes the form of a curved upward dash above the final character or its ''kāno''. e.g. ર્ભ ''rbha'', ર્ભા ''rbhā'', ર્ગ્મ ''rgma'', ર્ગ્મા ''rgmā''. **as a final member ***with છ ''chha'', ટ ''Ta'', ઠ ''Tha'', ડ ''Da'', ઢ ''Dha'' and દ ''da'', it is two lines below the character, pointed downwards and apart.

s ''ṭṭa'', ''ṭhṭha'', ''ḍḍa'' and ''ḍhḍha'': ટ્ટ, ઠ્ઠ, ડ્ડ, ઢ્ઢ. Also, ટ્ઠ ''ṭṭha'' and ડ્ઢ ''ḍḍha''. *As first shown with શ્ચ ''śca'', while Gujarati is a separate script with its own novel characters, for compounds it will often use the Devanagari versions. **દ ''d(a)'' as द preceding ગ ''ga'', ઘ ''gha'', ધ ''dha'', બ ''ba'' (as ब), ભ ''bha'', વ ''va'', મ ''ma'' and ર ''ra''. The first six-second members are shrunken and hang at an angle off the bottom left corner of the preceding દ/द. Thus દ્ગ ''dga'', દ્ઘ ''dgha'', દ્ધ ''ddha'', દ્બ ''dba'', દ્ભ ''dbha'', દ્વ ''dva'', દ્મ ''dma'' and દ્ર ''dra''. **હ ''h(a)'' as ह preceding ન ''na'', મ ''ma'', ય ''ya'', ર ''ra'', વ ''va'' and ઋ ''ṛ''. Thus હ્ન ''hna'', હ્મ ''hma'', હ્ય ''hya'', હ્ર ''hra'', હ્વ ''hva'' and હૃ ''hṛ''. **when ઙ ''ṅa'' and ઞ ''ña'' are first members we get second members of ક ''ka'' as क, ચ ''ca'' as च and જ ''ja'' as ज. ઙ forms compounds through vertical combination. ઞ's strokeless fragment connects to the stroke of the second member, jutting upwards while pushing the second member down. Thus ઙ્ક ''ṅka'', ઙ્ગ ''ṅga'', ઙ્ઘ ''ṅgha'', ઙ્ક્ષ ''ṅkṣa'', ઞ્ચ ''ñca'' and ઞ્જ ''ñja''. *The remaining vertical stroke-less characters join by squeezing close together. e.g. ક્ય ''kya'', જ્જ ''jja''. *Outstanding special forms: ન્ન ''nna'', ત્ત ''tta'', દ્દ ''dda'' and દ્ય ''dya''.

of written Sanskrit was completely phonetic, and had a tradition of not separating words by spaces. Morphologically it was highly synthetic, and it had a great capacity to form large compound words. Thus clustering was highly frequent, and it is Sanskrit loanwords to the Gujarati language that are the grounds of most clusters. Gujarati, on the other hand, is more analytic, has phonetically smaller, simpler words, and has a script whose orthography is slightly imperfect (''a''-elision) and separates words by spaces. Thus evolved Gujarati words are less a cause for clusters. The same can be said of Gujarati's other longstanding source of words,
