What does marielle in Japanese mean?

Answer 1

Marielle is not a Japanese name or word; it is French, and is a diminutive form of "Marie." The "elle" often indicates "little" or "younger," so it is essentially "little Marie." The name "Marie" derives from the name "Mary" or the Hebrew "Miriam," and has debated meanings, including "Star of the Sea" and "Sea of Sorrow/Bitterness."
