Learn Portuguese (Portugal): Até amanhã, na escola!

In Portuguese, people usually do not say 'see you'. Instead, they use até, which literally means 'until'. So, Até amanhã translates word-for-word as 'Until tomorrow'! You will see até used in many other common greetings, like até logo for 'see you later'.

Why is it na escola instead of just em escola?

In English, we say 'at school' without the word 'the'. But in Portuguese, you almost always need to include the definite article (the word for 'the') when talking about places. Na is a mandatory contraction made by combining the preposition em (in/at) and the feminine article a (the). So it literally means 'at the school'.

Does em always change to na for places?

It depends on whether the place is a masculine or feminine word. Because escola is feminine, em combines with a to make na. If the place were masculine, like trabalho (work), you would combine em with the masculine article o to make no, giving you no trabalho.
