Frequently Asked Questions
I've seen 'Entrar en' and 'Entrar a'. Which is correct?
Both are correct and widely used! 'Entrar a' (to enter to) is more common in Latin America, while 'entrar en' (to enter in) is more common in Spain. They mean the same thing, so you can use whichever you prefer.
Why do you say 'viajo en coche' but 'voy a pie'?
Great question! It's a set of rules you just have to memorize. For vehicles you get inside of (car, train, plane), you use 'en'. For modes of transport you are 'on' or that are part of you, you use other prepositions: 'a pie' (on foot), 'a caballo' (on horseback).
