Quizás (Spanish for “perhaps”) comes from the Latin qui sapi — literally, “Who knows?”. The sapi in that phrase is from the Latin for “to know”, sapere, from which root we get the English… savvy. Someone who is savvy just knows a lot about the subject!
The final -s of quizás maps to the first s- of savvy. And the -p- in sapere, although vanished from quizás, maps to the -vv- in savvy.
