Questions & Answers about Eu vou ao supermercado porque a promoção está boa.

Why is it ao supermercado instead of just a supermercado?

Ao is a contraction of a + o.

• a = the preposition to
• o = the masculine singular definite article the

So:

• ir ao supermercado = to go to the supermarket

In Portuguese, this contraction is required:

• a + o = ao
• a + a = à
• de + o = do
• em + o = no

Since supermercado is masculine and normally takes o, you get ao supermercado.

Could I also say vou para o supermercado?

Yes. Vou ao supermercado and vou para o supermercado are both natural in Brazilian Portuguese.

A useful general idea is:

• ir a often sounds a bit more neutral or traditional
• ir para often emphasizes destination a little more

In everyday Brazilian Portuguese, para o supermercado is very common. So both are fine:

• Vou ao supermercado
• Vou para o supermercado

Both mean essentially the same thing here.

Do I need to say Eu, or can I just say Vou ao supermercado?
