Nou te ale nan konsè a yè - Nou ale lekòl chak jou -- It looks like "nan" means 'to' but why is it in one sentence and not the other?

Nan → to, at, in

Sometimes the articles make the difference.  Take a look at the following examples:

Going to school → ale lekòl

Going to church → ale legliz

Going home → ale lakay

Going to New York → ale New York

Going to Mexico → ale Meksik

Going to a concert → ale nan yon konsè

Going to a theater → ale nan yon teyat

Going to a school → ale nan yon lekòl

Going to a restaurant → ale nan yon restoran.

Going to a wedding → ale nan yon maryaj

Going to a home → ale nan yon kay

Going to the store → ale nan magazen an

Going to the school → ale nan lekòl la
Going to this theater → ale nan teyat sa.

Let's go to this house → An ale nan kay sa.
Let's go home. → An ale lakay.
