Turbio, Spanish for “cloudy”, comes from the same Latin root as the English disturb: turbidus, meaning, “turmoil; full of confusion; muddy.”
It is easy to see how this one root evolved in time into both the English disturb and the Spanish turbio. Think of a cloudy day, just about to rain: the skies are in turmoil! The Gods are about to fight with one another!
We can see the t‑r-b root clearly in both. And the English turbid also comes from the same root, although that word is used only on the SATs.
