Questions & Answers about No supermercado, eu comprei tomate e cebola.

Why is it no supermercado and not just em supermercado?

No is a contraction of em + o:

• em = in / at
• o = the

So:

• em o supermercado → no supermercado

Portuguese uses these contractions very often. Here, no supermercado means in the supermarket or at the supermarket.

Because supermercado is a masculine noun, it takes o, not a. That is why it is no supermercado, not na supermercado.

Why is there a comma after No supermercado?

The comma separates the opening location phrase from the main part of the sentence.

• No supermercado, eu comprei tomate e cebola.

This is similar to English sentences like:

• At the supermarket, I bought tomatoes and onions.

The comma is natural because No supermercado has been moved to the front for emphasis or framing. You could also say:

• Eu comprei tomate e cebola no supermercado.

That version is also correct and very common.
