kingdom
👑🏰 reino = rey (king) + -no: the king's domain; cousin of English reign
From Latin regnum (kingdom), from rex/regis (king) — the same root that gives Spanish rey and reinar, and English reign, regal and royal. A reino is literally what a rey reigns over; by extension, any realm or world (el reino animal).
