• ‍ᠣ᠋ = the final form used in loanwords, as in ᠷᠠᠳᠢᠣ᠋ radio (радио radio).^{[10]: 48 [12]: 36 [13]}
• ‍ᠣ᠋‍ = medial form used after the junction in a proper name compound.^[12]: 44
• Derived from Old Uyghur waw (𐽳), preceded by an aleph (𐽰) for isolate and initial forms.^{[3]: 539–540, 545–546 [14]: 111, 113 [12]: 35}
• Produced with W using the Windows Mongolian keyboard layout.^[15]
