Origin: Hebrew, Spanish, Italian, Portuguese, Latin
Meaning: a Hebrew feminine form of Amariah meaning “Yahweh has said” or “Yahweh has promised”.
I’ve also seen it listed as an elaborated form of Amaro, an Italian, Spanish, and Portuguese name and surname of various meanings. Amaro could be from Germanic name Amalric meaning “work, labor/power”. In Sicily, Amaro came about from a nickname meaning “bitter”, “unlucky” or “disappointed”; it could also be derived from Arabic name ‘Ammar meaning “virtuous, devout”.
Amaro is also a Portuguese name of unknown meaning, perhaps influenced from Latin amor meaning “love”. There’s a Saint Amaro in Christian tradition.
Amaris could also be a contracted form of Amaryllis, the Spanish form of Greek Amarilis meaning “to sparkle”.
