mozo
/ˈmoθo/ · B2 · adj
boy, lad, young man, youth
👦 mozo = Latin mustus, 'new, fresh', so a fresh young person; sounds like MOE-so
Likely from Latin mustus (new, young, as in fresh must or grape juice). Young males were seen as fresh and new, and young unmarried men often worked as helpers, so mozo came to mean both lad and servant.
