Nita as an English name originated as a shortened form of names ending in nita such as Anita (a diminutive of Ana/Anna meaning “favor, grace” which ultimately derives from a Proto-Semitic root word), Juanita (diminutive of Juana, the Spanish equivalent of Joanna, the feminine form of John“Yahweh is gracious”); or Bonita, a Spanish/Portuguese word meaning “pretty, beautiful” which ultimately derives from a PIE origin.

Meaning: a nickname for Anita “grace, favor”, Juanita “Yahweh is gracious”, or Bonita “pretty, beautiful”; an Indian female name “modest, correct, well-behaved” and “led, guided”; a Choctaw word “bear”
Marie is the Czech and French form of Maria, the Latin and Ancient Greek form of Hebrew Miriam, a name of uncertain origin though several meanings have been ascribed to it such as “sea of bitterness”, “rebelliousness”, “obstinacy” or “wished for child” from a Hebrew root word. It’s also possible that it might have originated from an Egyptian name either meaning “beloved” from myr or “love” via mr.
