Amanda is a Latin feminine gerundive (i.e. verbal adjective) name meaning, literally, "she who must (or is fit to) be loved". Other translations, with similar meaning, could be "deserving to be loved," "worthy of love," or "loved very much by everyone." Its diminutive form includes Mandy, Manda and Amy. It is common in countries where Germanic and Romance languages are spoken. "Amanda" comes from ama- (the stem of the Latin verb amare, "to love") plus the feminine nominative singular gerundive ending (-nda).
