Ǯ (minuscule: ǯ) is a modified letter of the Latin alphabet, formed from ezh (ʒ) with the addition of a caron.
In the Uralic Phonetic Alphabet, it represents the sound [d͡ʒ].
Following its UPA usage, it was adopted in the Skolt Sami and Laz language alphabet for the same value. It typically appears doubled, where it represents a geminate /dd͡ʒ/. e.g. viǯǯâd "to fetch". Until 2007 it was also used by Olonets Karelian language.
