esclavo
/esˈklabo/ · B1 · noun · m
slave
⛓️ esclavo is a cognate of English slave: both come from Medieval Latin sclavus
Spanish esclavo and English slave both come from Medieval Latin sclavus. That word first meant Slav, because many Slavic captives were enslaved in the early Middle Ages. Remove the opening es- and sclav- is very close to slave.
