O with breve (ÃÂàþÃÂ; italics: <span style="font-family: times, Times New Roman, serif; font-size: larger">ÃÂàþÃÂ</span>) is a letter of the Cyrillic script. In all its forms, it is a homoglyph of the Latin letter O with breve (à  à  <span style="font-family: times, Times New Roman, serif; font-size: larger">à  à Â</span>).
O with breve is used in Itelmen, where it represents the extra-short close-mid back rounded vowel (although the newspaper Aboriginal of Kamchatka uses ÃÂ with ring above instead).
It is also used in an alphabet of Khanty instead of àwith diaeresis, where it represents the close-mid front rounded vowel [ø].
