Letter of related and vertically oriented alphabets used to write Mongolic and Tungusic languages
A is a letter of related and vertically oriented alphabets used to write Mongolic and Tungusic languages.
Transcribes Chakhar /ɑ/; Khalkha /a/, /ə/, and /∅/. Transliterated into Cyrillic with the letter а.
Medial and final forms may be distinguished from those of other tooth-shaped letters through: vowel harmony (e), the shape of adjacent consonants (q/k and ɣ/g), and position in syllable sequence (n, ng, q, ɣ, d).
The final tail extends to the left after bow-shaped consonants (such as b, and p), and to the right in all other cases.
ᠠ᠋ = medial form used after the junction in a proper name compound.
Separated suffixes starting with, or made up by the letter a include: ᠠ‑a (vocative or dative-locative), ᠠᠴᠠ‑ača (ablative), and ᠠᠴᠠᠭᠠᠨ‑ačaɣan (reflexive+ablative).

Note that this dictionary uses the transliterations c, ø, x, y, z, ai, and ei; instead of č, ö, q, ü, ǰ, ayi, and eyi; as well as problematically and incorrectly treats all rounded vowels (o/u/ö/ü) after the initial syllable as u or ü.
