Eli ben Yehudah ha Nazir ben Zechariah, Arabic Abu Kathir Yahya al Katib ("Father of Kathir, Yahya the Scribe" fl.Tiberias, 910s) was a grammarian and philologist of the Hebrew, Arabic and Aramaic languages. He may have been among the teachers in Tiberias of Saadia.
He was born in the year 1000
It does not say what year he was born, therefore it is neither incorrect or correct. The model must be confused.
