The Ol Chiki (ᱚᱞ ᱪᱤᱠᱤ) script, also known as Ol Chemetʼ (Santali: ol 'writing', chemet' 'learning'), Ol Ciki, Ol, and sometimes as the Santali alphabet invented by Pandit Raghunath Murmu in the year 1925, is the official writing system for Santali, an Austroasiatic language recognized as an official regional language in India. It has 30 letters, the forms of which are intended to evoke natural shapes. The script is written from left to right, and has two forms (Chapa and Usara); the latter form is not Unicoded. In both forms, this alphabet was invented as a unicameral script (in other words, as a script which does not have separate sets of uppercase and lowercase letters).

The shapes of the letters are not arbitrary, but reflect the names for the letters, which are words, usually the names of objects or actions representing conventionalized form in the pictorial shape of the characters.

History

The Ol Chiki script was created in 1925 by Raghunath Murmu for the Santali language, and publicized first in 1939 at a Mayurbhanj State exhibition.[2] Unlike most Indic scripts, Ol Chiki is not an abugida, but is a true alphabet: giving the vowels equal representation with the consonants.

Before the invention of Ol Chiki script, Santali was written in Bangla, Devanagari, Kalinga and Latin script. However, Santali is not an Indo-Aryan language and Indic scripts did not have letters for all of Santali's phonemes, especially its stop consonants and vowels, which make it difficult to write the language accurately in an unmodified Indic script.

For example, when missionary and linguist Paul Olaf Bodding, a Norwegian, studied the Santali language and needed to decide how to transcribe it (in producing his widely followed and widely respected reference books such as A Santal Dictionary), he decided to transcribe Santali in the Roman alphabet: despite his observation that Roman script lacks many of the advantages of the Indic scripts, he concluded that the Indic scripts could not adequately serve the Santali language because the Indic scripts lack a way to indicate important features of Santali pronunciation (such as glottalization, combined glottalization and nasalization, and check stops) which can be more easily represented in the Roman alphabet through the use of diacritics.[3]

The phonology of the Santali language had also been similarly analyzed by various other authors, including Byomkes Chakrabarti in Comparative Study of Santali and Bengali and Baghrai Charan Hembram in A Glimpse of Santali Grammar. However, the Ol Chiki alphabet is considered (by many Santali) to be even more appropriate for the language, because its letter-shapes are derived from the sounds of common Santali words and other frequent Santali morphemes[lower-alpha 1]: nouns, demonstratives, adjectives, and verb roots in the Santali language.[4] In other words, each Santali letter’s name is, or is derived from, a common word or other element of the Santali language, and each letter’s shape is derive from a simple drawing of the meaning of that word or other element. For example, the Santali letter “ol” (representing the sound /l/) is written with a shape originally derived from a simplified outline drawing of a hand holding a pen, because the name of this letter is also the Santali word for “writing.”

Ol Chiki forms

The existence of these two forms of Ol Chiki was mentioned by the script’s creator: Guru Gomke Pandit Raghunath Murmu (also known as Pandit Murmu) in his book Ol Chemed[5] which explains and teaches the Ol Chiki script[lower-alpha 2]. In describing these two forms, Pandit Murmu notes that the two forms are never mixed, but are always used independently of each other; unlike English or other Roman-alphabet language, where both lowercase and uppercase are used in the same word, in Ol Chiki the two forms are never used in the same word. Instead, the form called Ol Chiki (Chapa) (Santali: Chapa 'print') used for digital publication of books, newspapers, typing on mobile devices or computers; the other form, called Ol Chiki (Usara) (Santali: Usara 'quick'), is used only in handwriting: therefore, Usara is sometimes called Ol Chiki handwriting or cursive form. Although Usara is not unicoded, it is still widely used in order to writing Ol Chiki more easily, as a running hand.

Ol Chiki (Chapa)

Ol Chiki Chapa, or printed form, is widely used in keyboarding, and in printing newspapers, books, etc.

Ol Chiki (Usara)

Ol Chiki (Usara) or Usara Ol (Santali: Usara = Quick, Ol = Writing), also known as Ol Chiki handwriting or Ol Chiki cursive form, is one of the two forms of Ol Chiki script: one of the basic ways of writing in the Santali language. Using Ol Usara allows writing very fast, which would not be possible by writing in Ol Chiki (Chapa). The Usara Ol is limited to pen and paper, and does not find any use online. It is used, for instance, when students in school are taking notes. The handwritten Ol Usara letters consist of all the letters, digits and punctuation used by Ol Chiki (Chapa), except that the shapes of letters in Ol Chiki (Usara) are substantially changed from their forms in Ol Chiki (Chapa). In Ol Chiki, for instance, the diacritic ahad is used with ᱜ, ᱡ, ᱦ, ᱫ, and ᱵ, and all these can form cursive ligatures with ᱽ in Usara/handwriting (but not usually in Chapa/printed text).[6]. Further, Ol Usara seldom uses several letter-shapes which are formed by combining the ᱦ and four semi-consonants: ᱜ, ᱡ, ᱫ, and ᱵ with ahad. Similarly, in normal Ol Usara handwriting, the combination of ᱦ with ahad is not found, because in Ol Usara, it is generally written in a shorter form, as ᱷ.

Differences and Similarities between Both Forms

These are various differences and similarities between these two forms of Ol Chiki script.

Similarities

Sl.No	Ol Chiki (Chapa)	Ol Chiki (Usara)
1.	It consists of 30 letters, 5 diacritical marks, and one special symbol called ahad or ohod.	This is true of Ol Usara as well as of Ol Chapa
2.	Use of ᱦ with ᱽ is not found or is negligible. The combination of ᱦ with ᱽ is not found, as it is generally written in a shorter form: ᱷ (ᱦ + ᱽ = ᱷ)	This combination is likewise not found
3.	Digits are from ᱐ᱼ᱙	No change in digits
4.	6 Diacritics (ᱸ , ᱹ , ᱺ , ~ , ᱼ , ᱽ ) are present	No changes are made
5.	Except for the period, all punctuation takes the same form as in English. Instead of using a period, Ol Chiki uses a symbol called muchad or mucăd.	This is not changed in Ol Usara

Differences

Sl.	Ol Chiki (Chapa)	Ol Chiki (Usara)
1.	Ohod is written with its component letters separate (not joined)	Ohod is written with its component letters joined
2.	ᱜ, ᱡ, ᱦ, ᱫ, and ᱵ does not form ligatures with ᱽ (ᱦᱽ use is not found, instead ᱷ Is used)	ᱜ, ᱡ, ᱦ, ᱫ, and ᱵ form cursive ligatures with ᱽ (ᱦᱽ is not used; instead, ᱷ is used)
3.	Words are written with letters separated from each other, as usual in printed documents, without any cursive form.	Words are written in a cursive style with all letters joined.

Letters

Other marks

Ol Chiki employs several marks which are placed after the letter they modify (there are no combining characters):

Mark	Name	Description
ᱹ	găhlă ṭuḍăg	This baseline dot is used to extend three vowel letters for the Santal Parganas dialect of Santali:[9] ᱚᱹ ŏ /ɔ/, ᱟᱹ ă /ə/, and ᱮᱹ ĕ /ɛ/. The phonetic difference between ᱚ and ᱚᱹ is not clearly defined and there may be only a marginal phonemic difference between the two. ᱚᱹ is rarely used. ALA-LC transliterates ᱚᱹ as "ạ̄".[8]
ᱸ	mũ ṭuḍăg	This raised dot indicates nasalization of the preceding vowel: ᱚᱸ /ɔ̃/, ᱟᱸ /ã/, ᱤᱸ /ĩ/, ᱩᱸ /ũ/, ᱮᱸ /ẽ/, and ᱳᱸ /õ/. ALA-LC transliteration uses "m̐" after the affected vowel.[8]
ᱺ	mũ găhlă ṭuḍăg	This colon-like mark is used to mark a nasalized extended vowel. It is a combination of mũ ṭuḍăg and găhlă ṭuḍăg: ᱚᱺ /ɔ̃/, ᱟᱺ /ə̃/, and ᱮᱺ /ɛ̃/.
ᱻ	relā	This tilde-like mark indicates the prolongation of any oral or nasalized vowel. Compare ᱮ /e/ with ᱮᱻ /eː/. It comes after the găhlă ṭuḍăg for extended vowels: ᱮᱹᱻ /ɛː/. It is omitted in ALA-LC transliteration.[8]
ᱽ	ahad	This special letter indicates the deglottalization of a consonant in the word-final position. It preserves the morphophonemic relationship between the glottalized (ejective) and voiced equivalents of consonants.[9] For example, ᱜ represents a voiced /g/ when word initial but an ejective /k’/ when in the word-final position. A voiced /g/ in the word-final position is written as ᱜᱽ. The ahad is used with ᱜ, ᱡ, ᱦ, ᱫ, and ᱵ which can form cursive ligatures with ᱽ in handwriting (but not usually in printed text).[6] ALA-LC transliteration uses an apostrophe (’) to represent an ahad.[8]
ᱼ	phārkā	This hyphen-like mark serves as a glottal protector (the opposite function as the ahad.) It preserves the ejective sound, even in the word-initial position. Compare ᱜᱚ /gɔ/ with ᱜᱼᱚ /k’ɔ/. The phārkā is only used with ᱜ, ᱡ, ᱫ, and ᱵ. It is omitted in ALA-LC transliteration.[8]

Digits

Ol Chiki has its own set of digits:

Digit	0	1	2	3	4	5	6	7	8	9
Ol Chiki	᱐	᱑	᱒	᱓	᱔	᱕	᱖	᱗	᱘	᱙
Bengali	০	১	২	৩	৪	৫	৬	৭	৮	৯
Devanagari	०	१	२	३	४	५	६	७	८	९
Odia	୦	୧	୨	୩	୪	୫	୬	୭	୮	୯
Persian	۰	۱	۲	۳	۴	۵	۶	۷	۸	۹

Punctuation

Some Western-style punctuation marks are used with Ol Chiki: the comma (,), exclamation mark (!), question mark (?), and quotation marks (“ and ”).

The period (.) is not used, because it is visually confusible with the găhlă ṭuḍăg mark (ᱹ).[6]; therefore, instead of periods, the script uses single or two Ol Chiki short dandas:

• ᱾ (mucăd) marks a minor break
• ᱿ (double mucăd) marks a major break

Mixing the two letter styles

Although Ol Chiki (Chapa) and Ol Chiki (Usara) are normally never mixed, and the original inventor never mentioned mixing these letter styles, there have been some works that mix both forms, using them like English capital and small letters. However, this innovation is yet to be accepted officially.[12]

The invention of a lower case for Ol Chiki

Since 2017, Santali graphic designer, typographer, and film producer Sudip Iglesias Murmu has been working on design principles to provide a lowercase alphabet form for Ol Chiki, which would permit Ok Chiki writing and keyboarding to use a two-case, or bicameral, format (Using both uppercase and lowercase), as is done in many other written languages, including the Roman-alphabet languages such as English (all of which were once unicameral scripts, but evolved into a bicameral stage over time). As the development of a lowercase form is contributed to developing a standardized cursive form (in those writing systems which use one), the evolution of lowercase is likely to allow standardizing cursive to the point of making it type able alongside more rigid "block" printed letterforms forms So far, only Ol Chiki (Chapa) letters are used in keyboarding, typesetting, and publishing (in effect, producing capitals-only text for the entirety of all printed or keyboarded documents). In writing quickly by hand, Ol Chiki (Usara) is used: but, despite Ol Usara’s potential for reaching high speed, the circulation of Ol Usara documents is negligible, and Ol Usara is yet to receive Unicode standardization, thus leaving it still neglected.

In hopes to remedy this situation and to harmonize the two scripts, Sudip Iglesias Murmu has innovated by creating a series of lowercase letters, which he has integrated with the already existing font of Ol Chiki. According to him, providing lowercase letters increases the efficiency of keyboarding, both for Ol Chiki (Chapa) and for Ol Chiki (Usara), and allows keyboarding to reach the same speed that can be obtained when typing Santali in Roman-alphabet letters, which are likewise case-sensitive. However, his work is yet to be accepted officially.[13]

Прежде для записи языка сантали использовались бенгальский алфавит, алфавит ория или латинский алфавит (хотя большинство населения было неграмотным). Поскольку сантали не относится к индоевропейским языкам, данные алфавиты были для него неудобными, не соответствуя специфике языков мунда (например, в указанных алфавитах различались глухие и звонкие согласные, тогда как в языке сантали они чередуются в корне при словоизменении, поэтому их различение избыточно).
