Indistinguishable from ü, except where ö can be inferred from its context:
ö is found in medial or final syllables if it's also found syllable-initially.[2]: 11, 20 [7]: 9–10
ᠥ᠋ = an alternative final form; also used in loanwords.[12]: 39
The syllable-initial medial form ᠥ᠋ is also used in non-initial syllables in proper name compounds,[12]: 44 as well as in loanwords.[citation needed]
ᠥ᠌ = medial form used after the junction in a proper name compound.[12]: 44
Derived from Old Uyghurwaw (𐽳), followed by a yodh (𐽶) in word-initial syllables, and preceded by an aleph (𐽰) for isolate and initial forms.[3]: 539–540, 545–546 [13]: 111, 113 [12]: 35
Produced with O using the Windows Mongolian keyboard layout.[14]

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;: xii as well as problematically and incorrectly treats all rounded vowels (o/u/ö/ü) after the initial syllable as u or ü.[5]
