Introduction

Learning how to ask for permission in Brazilian Portuguese is a practical skill you will use in stores, libraries, homes, and public spaces. This article explains how to say Can I use this shelf? in everyday Brazilian Portuguese, breaks down key words, gives variations and polite options, and includes realistic dialogues and tips for beginners.

Core phrase: How to ask Can I use this shelf?

The direct, beginner-friendly way to ask Can I use this shelf? in Brazilian Portuguese is Posso usar essa prateleira?

Breakdown of the phrase:

Posso — from the verb poder, means can or may; used to ask permission.

usar — to use; the infinitive verb you need here.

essa — that (near the listener). For a shelf near you, you can also use esse or esta depending on context; see variations below.

prateleira — shelf; a common noun for shelves in stores, homes, libraries, or displays.

Useful vocabulary

Posso — can I / may I (polite permission)

Posso usar — can I use

essa prateleira — that shelf (near the listener)

esta prateleira — this shelf (near the speaker)

essa estante — that bookcase / shelving unit (alternative to prateleira)

está vazia — is empty

tem espaço — has space

posso colocar — can I put / place

um momento — one moment

obrigado / obrigada — thank you (male / female speaker)

When to use each demonstrative: essa, esta, esse

Use esta when the shelf is very near you, the speaker. Use essa when the shelf is closer to the listener or already mentioned. Use esse as another masculine form for objects, but prateleira is feminine, so prefer essa or esta.

Examples:

Posso usar esta prateleira? — I point to a shelf right next to me.

Posso usar essa prateleira? — I ask about a shelf near the person I’m speaking to or a shelf recently mentioned.

Polite variations and tone

Beginners often want to sound polite. Add por favor to make a polite request:

Posso usar essa prateleira, por favor?

For a more formal or very polite tone, you can use posso or could use poderia eu — though poderia eu sounds slightly old-fashioned or very formal in casual Brazilian Portuguese. A simple and common option is:

Posso usar essa prateleira? Obrigado.

Common short replies you might hear

Yes, of course — Pode sim or Claro.

No, it’s not possible — Não pode or Infelizmente não.

Wait a moment — Um momento, por favor.

There’s space — Tem espaço.

Practical tips for beginners

Use posso instead of posso eu. Posso eu is grammatically possible but sounds awkward; stick with posso plus the verb.

Match gender with demonstratives. Prateleira is feminine, so use essa or esta rather than esse.

Add por favor and obrigado/obrigada to sound polite. Brazilians appreciate simple courtesy words.

Listen for context words like espaço, ocupado, or problema to understand the reply.

When in doubt, point and say the phrase clearly: pointing helps comprehension in noisy places.

Common beginner mistakes and how to avoid them

Using esse with prateleira — remember prateleira is feminine; use essa or esta.

Forgetting por favor or obrigado — not a language error, but politeness matters.

Overcomplicating with formal structures like poderia eu — unnecessary for most casual situations; posso usar… works well.

Mispronouncing prateleira — practice pra-te-lei-ra, with clear vowels. Native speakers will understand even with imperfect pronunciation.

How to respond if you are the one granting permission

Say pode sim to grant permission politely: Pode sim, fique à vontade.

If the shelf is reserved, explain simply: Desculpe, essa prateleira é reservada.

Offer alternatives when denying: Não pode aqui, mas você pode usar aquela prateleira ali.

Pronunciation tips

Pronounce posso as POH-soo or POH-so. The double s has an S sound, not Z.

Say usar as oo-ZAR with stress on the second syllable.

Prateleira is pra-teh-LAY-rah with stress on the LAY syllable.

Por favor is POR fah-VOR, with the r like a soft H in many Brazilian accents; both POR favor and faz favor are common.
