raro
/ˈraɾo/ · A1 · adj
strange, odd
💎 raro = rare: same Latin root (rarus), but in Spanish it mostly means odd
From Latin rarus, thin or scarce, the same source as English rare. What is scarce feels unfamiliar, so Spanish stretched the word to strange. Qué raro = how odd. For plain scarcity Spanish often prefers escaso or poco común.
