Itta (איטא) is a Yiddish name of uncertain etymology — possibly from the Old German idis (woman). A traditional Ashkenazi name with deep Hasidic associations.
Itta of Metz (592-652) was the wife of Pepin I of Landen, ancestor of Charlemagne — a Frankish noblewoman who founded the Andenne Abbey.
Itta reduces to five — the number of Yiddish Hasidic.
