preocupación
/pɾeokupaˈθjon/ · B1 · noun · f
anxiety, worry
pre + ocupación = occupied before it happens: your mind is busy ahead of time
From Latin praeoccupatio, 'seizing beforehand'. A preocupación takes up your attention before the event even arrives. English preoccupation is the same word. The verb is preocuparse: ¿Te preocupa? means 'Does it worry you?'
