I see that sometimes the word "to" is translated as "bay" which is the verb to give.

That happens sometimes when some verbs are followed by the preposition "to". That word "to" is then translated as "bay" or "pou":

Examples:

Bring it to me.

Pote l *ban mwen. (uncontracted)

Pote l ban m. (contracted)

or

Pote l pou mwen. *(no contraction after "pou" when it indicates possession)

Read the book to her.

Li liv la ba li.

or

Li liv la pou li.

Send them to me.

Voye yo ban mwen

or

Voye yo pou mwen.

Return it to them.

Retounen li ba yo.

She came crying to me.

Li vin kriye ban mwen.

Explain it to them.

Eksplike l ba yo.

Let me hear it. Sing it to me.

Kite m tande l. Chante l ban mwen.

*Rules for using contractions
Ask me anything

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.
