The Ol Chiki (ᱚᱞ ᱪᱤᱠᱤ) script, also known as Ol Cemetʼ (Santali: ol 'writing', cemet' 'learning'), Ol Ciki, Ol, and sometimes as the Santali alphabet, was created in 1925 by Raghunath Murmu for the Santali language.

Previously, Santali had been written with the Latin script. However, Santali is not an Indo-Aryan language (like most other languages in the north of India), and Indic scripts did not have letters for all of Santali's phonemes, especially its stop consonants and vowels, which made writing the language accurately in an unmodified Indic script difficult. The detailed analysis was given by Byomkes Chakrabarti in his "Comparative Study of Santali and Bengali". Missionaries (first of all Paul Olaf Bodding, a Norwegian) brought the Latin script, which is better^{[citation needed]} at representing Santali stops, phonemes and nasal sounds with the use of diacritical marks and accents. Unlike most Indic scripts, which are derived from Brahmi, Ol Chiki is not an abugida, with vowels given equal representation with consonants. Additionally, it was designed specifically for the language, but one letter could not be assigned to each phoneme because the sixth vowel in Ol Chiki is still problematic.

Ol Chiki has 30 letters, the forms of which are intended to evoke natural shapes. The script is written from left to right.

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.

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:^[5] 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".^[3]
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.^[3]
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.^[3]
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.^[5] 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).^[4] ALA-LC transliteration uses an apostrophe (’) to represent an ahad.^[3]
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.^[3]

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

Punctuation

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

Period (.) is not used because it is visually confusable with the găhlă ṭuḍăg mark (ᱹ).^[4] Instead of periods the script uses two dandas:

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