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

! Mark !! Name !! Description
|-
| align=center | {{huge|ᱹ}} || găhlă ṭuḍăg || This baseline dot is used to extend three vowel letters for the Santal Parganas dialect of Santali:<ref name="TUS">{{cite web|url=https://www.unicode.org/versions/Unicode13.0.0/ch13.pdf#G29195|title=The Unicode Standard, Chapter 13.10: Ol Chiki|publisher=Unicode Consortium|date=March 2020|access-date=2020-03-21|archive-date=2020-07-05|archive-url=https://web.archive.org/web/20200705122344/http://www.unicode.org/versions/Unicode13.0.0/ch13.pdf#G29195|url-status=live}}</ref>  {{large|ᱚᱹ}} ŏ /ɔ/, {{large|ᱟᱹ}} ă /ə/, and {{large|ᱮᱹ}} ĕ /ɛ/. The phonetic difference between {{large|ᱚ}} and {{large|ᱚᱹ}} is not clearly defined and there may be only a marginal phonemic difference between the two. {{large|ᱚᱹ}} is rarely used.  ALA-LC transliterates {{large|ᱟᱹ}} as "ạ̄".<ref name="ALALC"/>
|-
| align=center | {{huge|ᱸ}} || mũ ṭuḍăg || This raised dot indicates [[nasalization]] of the preceding vowel: {{large|ᱚᱸ}} /ɔ̃/, {{large|ᱟᱸ}} /ã/, {{large|ᱤᱸ}} /ĩ/, {{large|ᱩᱸ}} /ũ/, {{large|ᱮᱸ}} /ẽ/, and {{large|ᱳᱸ}} /õ/.  ALA-LC transliteration uses "m̐" after the affected vowel.<ref name="ALALC"/>
|-
| align=center | {{huge|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'': {{large|ᱚᱺ}} /ɔ̃/, {{large|ᱟᱺ}} /ə̃/, and {{large|ᱮᱺ}} /ɛ̃/.
|-
| align=center | {{huge|ᱻ}} || relā || This tilde-like mark indicates the prolongation of any oral or nasalized vowel. Compare {{large|ᱮ}} /e/ with {{large|ᱮᱻ}} /eː/. It comes after the ''găhlă ṭuḍăg'' for extended vowels: {{large|ᱮᱹᱻ}} /ɛː/. It is omitted in ALA-LC transliteration.<ref name="ALALC"/>
|-
| align=center | {{huge|ᱽ}} || ahad || This special letter indicates the deglottalization of a consonant in the word-final position. It preserves the [[Morphophonology|morphophonemic]] relationship between the [[Glottalization|glottalized]] ([[Ejective consonant|ejective]]) and [[Voice (phonetics)|voiced]] equivalents of consonants.<ref name="TUS"/> For example, {{large|ᱜ}} represents a voiced /g/ when word initial but an ejective /kʼ/ when in the word-final position.  A voiced /g/ in the word-final position is written as {{large|ᱜᱽ}}. The ''ahad'' is used with {{large|ᱜ}}, {{large|ᱡ}}, {{large|ᱦ}}, {{large|ᱫ}}, and {{large|ᱵ}} which can form cursive ligatures with {{large|ᱽ}} in handwriting (but not usually in printed text).<ref name="L205243"/>  ALA-LC transliteration uses an apostrophe (ʼ) to represent an ''ahad''.<ref name="ALALC"/>
|-
| align=center | {{huge|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 {{large|ᱜᱚ}} /gɔ/ with {{large|ᱜᱼᱚ}} /kʼɔ/. The ''phārkā'' is only used with {{large|ᱜ}}, {{large|ᱡ}}, {{large|ᱫ}}, and {{large|ᱵ}}. It is omitted in ALA-LC transliteration.<ref name="ALALC"/>
