Word of the Day: Estudiar

Estudiar means 'to study', but in Costa Rica it's used more broadly to mean 'to read'. People would often say to someone trying to talk to me while I read, "Déjelo, ¿no ves que está estudiando"? (Leave him alone--don't you see that he's reading?) Confused by this reference at first, I used to respond, "Don't worry, I'm just reading", which was always met with odd looks.
