Learn about three important prepositions - EN, DE and A. Let's have a look at some of those little words that sit in between. Some are called prepositions. Here are three: EN - IN (en la ciudad, en el campo, en mi bolsillo). DE - OF or FROM, (lejos DE la Universidad (Far from the University), soy de Argentina (I'm from Argentina)). A - TO or AT (a la derecha, (at right / to the right), a la izquierda, (at left / to the left))
