inquieto
/inˈkjeto/ · B2 · adj
restless, agitated, unquiet, cross
🐜 in- (not) + quieto (still, quiet) = not quiet, can't keep still
From Latin inquietus, which means un-quiet: the in- that negates, plus quietus, meaning at rest. English has the same pair in quiet and disquiet. Someone inquieto has no calm, either in the body (fidgety, restless) or in the mind (worried, anxious).
