Portuguese beginner guide to saying what something is not

Introduction

This beginner guide explains how to say that something is not something in Brazilian Portuguese. You will learn useful negatives, common structures, simple examples, vocabulary, and everyday phrases so you can deny, correct, or clarify information naturally in conversation, signs, menus, and messages.

Basic negative words and their use

Start with the simplest negative word: não. This word means not or no and is the backbone of negation in Brazilian Portuguese. Place não before verbs, adjectives, and sometimes before nouns to make a negative statement.

Examples:

Não sei.
Meaning: I don’t know.

Não é caro.
Meaning: It is not expensive.

Não sou estudante.
Meaning: I am not a student.

Negating nouns and identities

When you want to say what something or someone is not, use não with a form of the verb ser (to be) or estar (to be for states). The verb you choose depends on whether you are describing identity or temporary condition.

Use ser for identity or characteristics:

Ele não é meu irmão.
Meaning: He is not my brother.

Isso não é verdade.
Meaning: That is not true.

Use estar for temporary states or locations:

A loja não está aberta.
Meaning: The store is not open.

Eu não estou com fome.
Meaning: I am not hungry right now.

Negating actions and abilities

To say someone does not do something, use não with the present tense of the verb. This is the most common pattern.

Examples of verbs negated:

Eu não gosto de café.
Meaning: I do not like coffee.

Ela não fala inglês.
Meaning: She does not speak English.

Nós não podemos entrar.
Meaning: We cannot enter.

When using modal verbs like poder (can) or dever (should), place não before the verb form:

Você não pode fumar aqui.
Sign: You cannot smoke here.

Eu não devo fazer isso.
Meaning: I should not do that.

Common negative expressions and short replies

Beginners should learn short negations for everyday conversations. These are helpful for quick refusals, corrections, or confirmations.

Common short replies:

Não – No / Not

Não sei – I don’t know

Nem – Not even / neither (used with tampouco or other negatives)

De jeito nenhum – No way / Not at all

Examples in context:

— Você está pronto?
— Não.
Meaning: Are you ready? No.

— Ele falou com você?
— Não sei.
Meaning: Did he talk to you? I don’t know.

Using negative pronouns: nobody, nothing, never

Portuguese uses negative pronouns like ninguém (nobody), nada (nothing), and nunca (never). These often follow não, but in some constructions they appear without an additional não. For beginners, using não + verb + negative pronoun is easiest.

Examples:

Eu não vi ninguém.
Meaning: I didn’t see anyone.

Não há nada aqui.
Meaning: There is nothing here.

Ele nunca veio.
Meaning: He never came.

Note that with nunca you usually do not add não because nunca itself means never. For clarity, beginners can say não + nunca in very informal speech, but standard is to use one negative word.

Negative questions and tag questions

When asking negative questions, keep não in front of the verb or use question words. Tag questions like right? or isn’t it? can be translated in multiple ways. The most neutral beginner-friendly tag is não é? or né? (colloquial).

Examples:

Você não gosta de sopa?
Meaning: You don’t like soup?

Isso não é verdade, né?
Meaning: That is not true, right?

Essa cadeira não é confortável?
Meaning: This chair is not comfortable?

Correcting someone or clarifying with negatives

Beginner learners will often need to correct statements. Use nao with a correction phrase like pelo contrário, mas, or sim/ao contrário to soften corrections.

Examples:

— Você é médico?
— Não, sou engenheiro.
Meaning: Are you a doctor? No, I’m an engineer.

— Isso é difícil?
— Não, pelo contrário, é fácil.
Meaning: Is that difficult? No, on the contrary, it’s easy.

— Ela é brasileira?
— Não, ela é argentina.
Meaning: Is she Brazilian? No, she is Argentine.

Everyday signs and short phrases you will see

Recognizing negative signs can help in travel and daily life. Here are common negated phrases found on signs, menus, and forms.

Common phrases:

Não fumar – No smoking

Não entre – Do not enter

Não aceitamos cartão de crédito – We do not accept credit cards

Não disponível – Not available

Examples on menus or schedules:

Prato do dia: arroz, feijão, frango
Observação: Não inclui sobremesa.
Meaning: Dish of the day… Note: Does not include dessert.

Horário de atendimento: 9h–17h
Fim de expediente: Não aberto aos domingos.
Meaning: Business hours… Not open on Sundays.

Practical tips for beginners

Use these tips when forming negative sentences in conversation and writing.

Tip 1: Place não directly before the verb in simple statements. This is the most common structure and sounding natural depends on correct placement.

Tip 2: Use ser for identity and estar for temporary states. If unsure, think: is this a permanent fact or a temporary situation?

Tip 3: Memorize negative pronouns: ninguém, nada, nunca, nada. These make your speech clearer and more native-like.

Tip 4: Listen to native speakers and notice contractions like né (colloquial tag) and phrases like de jeito nenhum for strong refusal. Copy short phrases first.

Common beginner mistakes and how to avoid them

Mistake 1: Double negatives in places where they change meaning. In Portuguese, double negatives are often correct and reinforce negation, but beginners can accidentally cancel meaning by mixing structures incorrectly. Stick to one clear negative pronoun or use não + verb + pronoun pattern.

Example to avoid:

*Eu não vi nada nunca.
Better: Eu não vi nada. or Eu nunca vi nada.
Meaning: I didn’t see anything.

Mistake 2: Using ser when describing temporary states. Saying Eu sou cansado sounds like a personality trait. Use Eu não estou cansado for temporary tiredness.

Mistake 3: Forgetting agreement with verbs and subjects. Pay attention to verb conjugation after não. For example, Nós não somos estudantes is correct, not Nós não é estudantes.
