0. INTRODUCTION

The term script grammar refers to the behaviour pattern of the writing system of a given
language. Languages which have written representations do not use a haphazard manner
of storing the information within the system, but use a coherent pattern which is similar
to the linguistic grammar of a given language. With the help of specialists (not
necessarily linguist) who work in the area of the written representation of the language,
the manner in which the shapes of the characters of the language and the representation
of the conjunct forms is provided. In other words the Script Grammar deals with the
surface structure of the language and tries to provide the best possible fit for shapes
and their representation. Since this is a highly subjective issue, the shapes provided here
are recommendations at the best and conform to the perception of the mandating
body/evaluators who consensually arrive at the best possible fit which is acceptable to
a majority of users. An example from the Devangar script will make the above clear.
Although Marathi and Nepali share the same script Devangar, not only do they not
share the same character inventory but in addition the representation of certain characters
is different. Thus the Nepali /la/ is different from the Marathi /la/ in so far as the
placement of the stem is concerned Nepali Marathi . This ensures that the Script
Grammar conforms to the language in question and provides the character shapes
acceptable to a given user community. It should be noted that this does not mean
monotony. The Marathi and Nepali /la/ can have a variety of forms once the intrinsic
structure of the character is determined.

Script Grammar is the term used to define:
the writing system used to inscribe a given language
the history of the script and language (wherever available)
the syllabic structure of the writing system of the language
the rule ordering of the characters within the syllable (akshar)
description of the syllabic clusters
collation order of the characters: lexical / dictionary sorting order

1. OBJECTIVES OF SCRIPT GRAMMAR

The Objectives of the script grammar for each language can be divided into two major
parts:

Societal:
Provide a visual representation of shapes that are deemed to be in conformity with
the perception of a given community

Ensure thereby that this perception is safe-guarded

Through wide-spread dissemination and creation of appropriate tools ensure that
within the given linguistic community, all media tries to adopt the given shape.

Technical:
Classify the language in terms of its ISO and also whether it belongs to the Abjad,
Akshar (Alphasyllabary) class.

Provide an inventory of the characters pertinent to the language and classify the
same in terms of their taxonomy.

As a corollary determine whether the inventory is in conformity to the Syllable
formalism as stipulated in ISCII91 and subsequently adopted by Unicode.

Since Brahmi is written from left to right, and since certain characters do not
follow the linear L to R order, provide an inventory of displaced catenators i.e.
characters such as Mtrs that concatenate to the Consonant

Propose the best shape representation of the individual characters as well as of the
ligatures used within a given script. As a corollary request the expert(s) to identify
the largest possible strings of such ligatures.

Finally provide the collation order pertinent to that script/language, which would
be of great utility to high-end NLP as well as to CLDRs in the pertinent
language. Thus for example, the collation order for Marathi is different from
Hindi although both languages share the same script. Thus in Marathi , are
placed at the end of the consonant inventory i.e. after in the sort order. In Hindi
is sorted along with and with

2. END USERS FOR SCRIPT GRAMMAR


The script-grammar specific to a given language can be used by a large number of users.

Most importantly it can be used by font developers desirous of developing a font
which is compliant with the perception of the characters and ligatures of a
language by its user community.

Certain features of the script grammar such as the shapes can also be used for
testing OCR and OHWR. Similarly information regarding Ligatures as well as
collation order can help in high-end NLP work such as detecting invalid
combinations, correct implementation of syllable structure, prediction routines to
name a few. Information regarding collation and character sets can be also used
for CLDR.

They allow the font designer to design a font which is in compliance with the
norms and standards of that particular script. A major problem which will be dealt
with in the template is one of ligatures. The final list of ligatures defined by the
script grammar allows the font designer to write specific rules for such glyphs.

It permits the software developer to design and implement the keyboard and the
input mechanism which will meet the requirement of the particular linguistic
community.

The collation or sort order as described in a Script Grammar permits the software
developer to write software functions/ routines for sorting data in all applications.

Script Grammars are equally important for keyboard design, especially when
supplemented by frequency data from a corpus.

As can be seen the script grammar has a wide range of use and can be of utility to font
developers, Indian language developers and linguists in the area of computation.

4. TERMINOLOGY
1


Abjad: A writing system in which each symbol always or usually stands for a consonant.
The long vowels are indicated. However the short vowels are rarely marked and the
reader needs to supply these. Example: Urdu written in Perso-Arabic Script is an example
of this writing system.

Abugida: also called an alphasyllabary, is a segmental writing system in which
consonantvowel sequences are written as a unit: each unit is based on a consonant letter,
and vowel notation is obligatory but secondary
2


Akshar: see Abugida

Allographs: Variants of the representation of a character. Thus ae and [U+00E6] in
Latin alphabet are allographs.

Allo-Script: The term relates to languages which share a common script. Thus
Devangar is used to write 9 official languages. However these languages do not use the
same set of characters. Thus Marathi uses the retroflex lla [U+ 0933] which Hindi
does not use. Flaps used in Hindi [U+095C] [U+095D] are not used in Marathi.
These sub-sets of scripts based on a single matricial script are termed as allo-scripts.

Alphabet: A set of letters used in writing a language. Example: The English Alphabet.

Aspirated consonant: A consonant which is pronounced with an extra puff of air coming
out at the time of release of the oral obstruction. This has a sound of an extra "h".

Basic alphabet: The minimal set of letters which can be used for uniquely encoding
every word of a language. The basic alphabet for English consists of only the upper-case
letters A-Z

Catenators: Also termed as Concatenators are characters which are concatenated to
another character. In the Brahmi script these are the Mtrs or Vowel modifiers which are
adjoined to the consonant and add a vocalic value to the consonant.

Conjunct: The Indic scripts are noted for a large number of consonant conjunct forms
that serve as orthographic abbreviations (ligatures) of two or more adjacent letterforms.
This abbreviation takes place only in the context of a consonant cluster. Under normal
circumstances, a consonant cluster is depicted with a conjunct glyph if such a glyph is
available in the current font. In the absence of a conjunct glyph, the one or more dead

As in the case of the BIS Document, in order to make the terminology accessible for all readers, examples
have been chosen from English/Latin scripts, wherever possible. Some definitions have been excerpted
from the BIS ISCII91 document and suitably modified where necessary.
2
Wikipedia definition


8

consonants that form part of the cluster are depicted using half-form glyphs. In the
absence of half-form glyphs, the dead consonants are depicted using the nominal
consonant forms combined with visible virama signs.
3


Consonant: A letter representing a speech sound in which the breath is at least partly
obstructed.

Diacritic:A mark added to a letter which distinguishes it from the same letter without a
mark, usually having a different phonetic value or stress.

Displaced Catenator: (see Catenator) Within the Brahmi script, the writing system is
linear and moves from left to right. However in the case of some catenators this rules is
not observed and the catenator (wholly or partially) is placed to the right of the consonant
to which it relates. The short vowel I // in Devangar is an example of a displaced
catenator.

Display composing: The process of organizing the basic shapes available in a font in
order to display (or print) a word.

Display rendition: The process by which a string of characters is displayed (or printed).
In this process several consecutive characters may combine with each other on the screen.
The sequence of display of the characters may become different.

Eyebrow repha: (See Eyelash ra)

Eyelash ra: The eyelash ra is used in Konkani, Gujarati and Marathii. It is treated as
different from the (repha) by certain linguists. While the former is treated as a flap, the
latter is a continuant trill (cf., Kalyan Kale and Anjali Soman. 1986).

Font: A set of symbols used for display or printing of a script in a particular style.

International numerals: The conventional 0 to 9 digits used in English for denoting
numbers. these are also known as Indo-Arabic numerals (to differentiate them from the
Roman numerals like IX for 9).

Latin alphabet: The alphabet used for writing the language of ancient Rome. Also
known as the Roman alphabet. The alphabet is used today for writing English and
European languages.

Letter: A character representing one or more of the simple or compound sounds used in
speech. It can be any of the alphabetic symbols.

Ligature: (see Conjunct)


3
Unicode ver. 6.0 Chapter 9.0 pp 6-7


9

Nasal consonant: A consonant pronounced with the breath passing through the nose.
Example m n in English.

Nasalized vowel: A vowel pronounced with the breath passing both through the nose and
the mouth. In Indian scripts this is denoted by a Chandrabindu and gives the vowel/vowel
modifier over which it placed a nasal value. Example:

Phonetic alphabet: An alphabet which has direct correspondence between letters and
sounds Example: The International Phonetic Alphabet..

Pure consonant: A consonant which does not have any vowel implicitly associated with
it.

Rafar: A special case of a ligature constituted by the adjunction of ra followed by a
halanta to consonant. The resultant combination places the ra on top of the consonant to
which it is adjoined. In case the consonant itself is adjoined to another consonant, the
rafar is placed above the consonant e.g.in Devanagari: += , ++=

Rakar: A special case of a ligature constituted by the adjunction of a consonant followed
by a halanta to ra. In a large number of Brahmi scripts the ra is adjoined to the stem of
consonant to which it relates. In the case of consonants which have no stem such as the
dental retroflexes in Devangar, the rakar is placed below the consonant to which it
relates.

Repha: (see Rafar)

Roman script: The script based on the ancient Roman alphabet, with the letters A-Z and
additional diacritic marks. Used for writing a language which is not usually written in the
Roman alphabet.

Script: A distinctive and complete set of characters used for the written form of one or
more languages.

Script numerals: The 0 to 9 digits in a script, which have shapes distinct from their
international counterparts.

Syllable: A unit of pronunciation uttered without interruption, forming whole or part of a
word, and usually having one vowel or diphthong sound optionally surrounded by one or
more consonants

Transliteration: Representation of words with the closest corresponding letters in an
alphabet of a different language.

Vowel: A letter representing a speech sound made with the vibration of the vocal cords,
but without audible obstruction



10

Vowel sign: A graphic character associated with a letter, to indicate a vowel to be
associated with that character (Mtr in Hindi).

5. PHILOSOPHY AND UNDERLYING PRINCIPLES

The script grammar is based on the following principles:

1. The Grammar aims to depict the surface grammar of the written language: the
manner in which characters as well as conjuncts are depicted

2. Where a given script admits many languages, it is pre-suppose that such
languages will prescribe different representations for a given shape or
conjunct according to the perception of the native users of that language

3. Corollary to the above the result is a script and allo-scripts i.e. a given script
shared by many languages is not uniformly deployed across all the languages
but is subject to variations and modulations.

4. The term Grammar is used here in a non-normative sense: what is prescribed
is in the form of recommendations provided by experts who visualize the
shape of the given script in their mother tongue in a specific manner.
Subjective variations may occur
4


5. The Grammar is limited to its synchronic use i.e. the manner in which a given
language as of today admits a character set within the script used to write it. It
is not diachronic or historical in nature and does not study the evolution of the
given script across centuries.

4
It is recommended that such variations be culled by placing the Grammars of different scripts in public
review.

6. SCRIPT GRAMMAR STRUCTURE

The script grammar provided below has the following parts.

Part 6.1. deals with peripheral elements such as the ISO of the language, the writing
system used: (Alphasyllabic) Abugida or Abjad.

Part 6.2. treats of the syllabic structure. It verifies whether the character set of the
language complies with the ISCII syllabic structure and if not which cases are not
compliant.

Part 6.3 is the script grammar proper and describes the character set as well as the
conjunct shapes of the given script along with the collation order



13


6.1. PERIPHERAL ELEMENTS OF THE SCRIPT GRAMMAR

These constitute the elements that are peripheral to the Script Grammar. The main
parameters considered are the mnemonic and name of the language (needed for CLDR
and also for language tags), the writing system used to inscribe the language and
wherever possible a short history of the language.

6.1.1. Name of the language and its representation in the 3 letter mnemonic as per
ISO 639.1. & 639.3

Name of the Language: GUJARATI
ISO Mnemonics: guj

This refers to a one line description of the language and its mnemonic representation as
per the ISO.


6.1.2. Identification of the writing system(s) used to inscribe the given language
Gujarati is written using the Gujarati script. It is an alphasyllabary with the akshar
as its core.

This is a one line description of the script used to write the language. However in case
the language uses more than one script, all the scripts in question are specified, provided
these constitute the official language of the given state.
All scripts derived from Brahmi are Abugidas i.e. syllabary driven systems. The main
features of Abugidas are as under:
The consonant has an implicit vowel built-in which is normally the schwa.
The inherent vowel can be modified by the addition of other vowels or
muted by a diacritic termed as a Virama or Halanta
Vowels can be handled as full vowels with a vocalic value
When two or more consonants join together they form ligatures which can
be recognized by their shape or alternatively form an entirely new shape
+ = .
Abugidas/Alphasyllabaries because of their syllabic structure require a special
description which is the subject of the discussion in 6.2. below.

6.1.3. Amendments needed in Unicode for Gujarati language

None have been proposed by the Gujarati Sahitya Parishad which has mandated the
script grammar.


14


6.2. CONFORMITY TO THE SYLLABLE STRUCTURE

Gujarati language complies with the syllable (akshar) structure described above. It
can admit up to 3 consonant clusters.

Alphasyllabaries are determined by the notion of the syllable or the Akshar. The
compositional grammar of the syllable determines it well-formedness. This is through a
series of formal constraints based on a Backus-Naur Formalism which is given below.
The syllable (akshar), first defined in the ISCII document (1991), identifies the following
character sub-sets for the purposes of identifying the syllable (akshar). In what follows
the syllable analysis will be restricted to Gujarati.

(C) Consonants
3 - "
O ^
8 ' 8 Q
d
>
-
C

(V) Vowels

- - U 3 - - - - - -


(M) Mtrs or Vowel Modifiers

t l l t t t

(D) Diacritics

: Anuswar

Anuswara, a nasal, denoted by a dot above the letter after
which it is to be pronounced. This falls under Nasal category.
:Chandrabindu
Chandrabindu, a nasal, denoted by a breve with a dot
superposed above the letter after which it is to be pronounced.
This falls under Nasal category.
Visarga

Visarga, denoted by two dots placed above the other.


15

: Avagraha
For extra length with long vowels as seen in the Sanskrit text
dtq


(H):Halanta - Halant used in most writing systems to signify the lack of an inherent
vowel.

(N)
5
Nukta - is Not used in Gujarati

Each of these sub-types has its restrictions in terms of what can precede or follow it
within a syllable (akshar), as shown in the table below:










C can be preceded by H or no subtype and followed by any one of the following: M,D,H
V can be preceded by no subtype and followed by D but not by another sub-type.
M can be preceded by C and followed by D.
D can be preceded by C, V, M and followed by no other subtype. It closes the syllable
(akshar).
H can be preceded by C alone and followed only by C and no other sub-set.

6.2.1. Syllable (akshar) Types

The formalism defines the syllable (akshar) in terms of both what can constitute a
syllable (akshar) and what cannot. A valid syllable (akshar) as per this definition can be
of only two types:

1. A vowel syllable (akshar): a full vowel.
2. A consonant syllable (akshar): a full consonant (having a mtr )

The three other subsets viz. Mtrs, Diacritics, Halanta cannot constitute a syllable
(akshar) by themselves or in combination among themselves.

6.2.1.1. The Vowel syllable (akshar) is of the following types:


5
The nukta is a small dot placed under a character in Northern scripts to show that they are flapped or for
deriving 5 other consonants in the Devangar and Punjabi scripts, required for Urdu ,,,,
PRECEDED BY SUBTYPE FOLLOWED BY
-, H C M,D,H
- V D
C M D
C,V,M D -
C H C


16

6.2.1.1.1. A pure vowel all by itself: - /a/ - // etc.
6.2.1.1.2. A vowel followed by a modifier i.e. either a nasal marker or a visarga or an
avagraha: / /, - / H / - /:/

6.2.1.2. The Consonant syllable (akshar) can be of the following types:
6.2.1.2.1. A full consonant (with or without Nukta) i.e. with the inherent vowel : 3 : /ka/
6.2.1.2.2. A consonant followed by a mtr i.e. the inherent vowel being substituted by
another vowel: 3l /ki:/
6.2.1.2.3. A consonant followed by a modifier: 3 /k /, C /haH
6
/
6.2.1.2.4. A consonant followed by a mtr and a modifier: /k/, /duH/.
6.2.1.2.5. A consonant cluster i.e. a dead or half consonant (Consonant+Halanta)
followed by a full consonant followed optionally by a mtr, a modifier or a combination
of both. These result in a ligature or what is often termed as yuktakshara.
3 /tka/ 3 /tka /, 3 /tkaH/ 3 /tk/, 3 /tku/.
The above permutations and combinations result in 7 major syllable (akshar) types. Of
these the last type introduces the problem of the number of consonant clusters. ISCII (91,
p.23) provides for up to three consonant clusters as the worst case i.e. the largest
possible string. This is functional for modern Prakrits where the largest consonantal
cluster rarely exceeds three consonant. Sanskrit is an exception where in a single word,
four consonants can come together: /krtsnya/ "wholeness", "entirety".

This means that theoretically the following forms can be postulated:
1. Vowel Set: With the Vowel as the node.
V VD
2. Consonant set: With the Consonant as the node (an implicit or modified
vowel is pre-implied).


Node Mtr Modifier Mtr+Modifier
C CM CD CMD
CHC CHCM CHCD CHCMD
CHCHC CHCHCM CHCHCD CHCHCMD
CHCHCHC CHCHCHCM CHCHCHCD CHCHCHCM

A total number of 16 theoretical syllables is therefore possible. It will be seen that the
written syllable (akshar) is not very different in structure from the phonetic syllable and
that the movement from the written to the spoken levels is made feasible by application
of certain rules.


6
This character represents phonetically the weak implicit vowel, termed as schwa and often shown as /a/
also.


17

This formal structure of the syllable (akshar) explained above is common to all Brahmi
based scripts (with a few variations). It will form the basis of an exhaustive description of
the characters as well as their ligatural representations.

6.3 SCRIPT GRAMMAR PROPER

This section lays down in detail the different parameters of the Script Grammar for
Gujarati. These are:

6.3.1. The Character Set of Gujarati.
6.3.2. The Consonant mtr combinations of Gujarati.
6.3.3. The Ligature Set of Gujarati.

This section provides detailed information about the characters in the language and the
list of the same and also more importantly shows the manner in which the character is to
be written. Each subsection comprises therefore two parts: the basic character set and the
shape each character should have, as mandated by the experts who have designed the
script grammar of Gujarati.

This comprises the following:

As per expert recommendations the character set should be written as under:
t, l, l, , , , , , , t, t, t,

6.3.1.4. Displaced Catenators
Under normal circumstances Vowel Modifiers also known as catenators (since they
concatenate to the preceding consonant) in Brahmi based scripts are written from left to
right in linear order (with the exception of Consonant stacks). However certain modifiers
are displaced and are placed to the left of the consonant to which they concatenate. As a
general rule in all Devangar script driven languages there is only one displaced
catenator:

CATENATOR POSITION EXAMPLE
l
To left of character
l3,ld,l-
6.3.1.5. Shape of the combination of ra (rakar,repha)
The takes a variety of shapes known as rakar and repha (rafar) depending on its
position. When conjoined before a consonant by means of the halanta, it changes shape
and is placed on top of the consonant or consonant clusters to which it relates. This is
called a repha or rafar. Gujarati admits a special repha known as eyelash ra. When it is
conjoined after a consonant with the help of a halanta, it appends to the consonant in the
shape of a slanting stroke attached to the stem (side rakar) or in the case of consonants
which have no stem such as , it is appended in the shape of a ^ to the bottom of the
character (bottom rakar). Gujarati has the following combinations of ra:

RAFARS
Top rafar: 5 for ex top rafars will be formed in case of following words.

e.g. / dtq /

6.3.1.7. Numerals
Following are the numbers used in Gujarati language.

6.3.2. Consonant Mtr Combinations.
These refer to the shapes generated when a Mtr is adjoined to the Consonant. The
layout of these is in the shape of a matrix where the first horizontal row refers to the
active consonant and the first vertical column refers to the vowel-modifier.

Due to constraints of space and also for reasons of clarity, for each class a series of 3
tables are provided.

Table 1: 3 - " O ^
Table 2: 8 ' 8 Q d
Table 3: > -
C

Wherever there is an X it implies that the experts have deemed that such a combination is
not used in the language. However for the font developer this is an indication that for this
particular combination which is not existent in the language but needs to be
accommodated in the font table, a simple linear combination be provided.
e.g. Although the combination of " +Mtr is theoretically not possible it needs to be
handled at the font level in the anticipation that a user could type this combination. The
font would show the following: "t
The classes are as under:
6.3.2.1. refers to a simple concatenation of Consonant and Mtr combinations.
6.3.2.2. refers to a concatenation of Consonant and Mtr + Nasal marker combinations.
Other diacritics such as avagraha and visarga have been avoided, since these are linear in
nature, are adjoined to the combination and do not in any way modify the structure of the
shapes.

6.3.3. The Ligature Set of Gujarati.
Gujarati has a large set of ligatural forms. These are combinations of
Consonant+Halanta+Consonant (CHC) or CHCHC or even rarer CHCHCHC. The CHC
combinations which are the most frequent are arranged in the shape of a matrix: the
abscissa or horizontal axis refers to the Consonant which constitutes the ligature and the
ordinate or vertical axis shows the consonant which forms the ligature and which is
followed by a halanta.
As in 6.3.2. the ligature sets are divided into the following
6.3.3.1 CHC (in a matrix)
6.3.3.2 CHCHC
6.3.3.3.CHCHCHC
6.3.3.1. CHC ( combination of two consonanats)
These ligatures are presented as in the earlier case of Consonant+Mtr combinations in
three sets. A lot of slots have an X marked, showing that the experts have deemed that
such a ligature is not possible in the language. However in these cases, the font
developer is to assume that the ligature is linear in nature.
The following set shows a combination of two consonants. To know how particular
combinations forms, select one consonant from the first column and second from first
row. For eg. Combination of consonant 3 and 3 is ligature .

6.3.4 The Collation Order of Gujarati.
Collation is one of the most important features of a script grammar. It determines the
order in which a given culture indexes its characters. This is best seen in a dictionary sort
where for easy search words are sorted and arranged in a specific order. Within a given
script, each allo-script may have a different sort-order. Thus in Devanagari the conjunct
glyph is sorted along with , since the first letter of that conjunct is and on a similar
principle is sorted along with . Different scripts admit different sort orders and for all
high-end NLP applications, sort is a crucial feature to ensure that the applications index
data as per the cultural perception of that community. In quite a few States, sort order is
clearly defined by the statutory bodies of that state and hence it is crucial that such sort
order be ascertained and introduced in the script grammar.
In the case of Gujarati the following is the traditional sort order as determined by the
experts. The order as given below is pertinent to sorting by a computer program and is
compliant with CLDR as laid down by Unicode and W3C.
