Bas Paroh calls him "Moshe" [or affectionately "Moishe"] כי מן המים משיתיהו - Because he was pulled from the water.
What language did Bas Paroh speak? Hebrew? No. Yiddish? No. French? No. She spoke EGYPTIAN!!! So the question is - Did she give him an Egyptian name ["Chwlapahooti"?] and the Torah translated it into Hebrew or did she [in deference to his being a "Hebrew"] actually give him a Hebrew name??
