Overview: What each pair means
Ou…ou means either…or and introduces alternatives or choices. It is used when a speaker offers options, possibilities, or mutually exclusive outcomes.
Nem…nem means neither…nor and expresses the negation of two items, actions, or qualities at the same time. It denies both elements in the pair.
Basic structure and word order
How Ou…ou works
Use Ou…ou by placing it before the first and second option, or only between the items. Both forms are natural:
Ou você vem, ou eu vou sozinho.
Você vem ou eu vou sozinho.
With verbs, keep normal conjugation for each clause. When the two options are clauses, a comma before the second ou is optional but common for clarity:
Ou ele aceita o acordo, ou a reunião termina hoje.
Ou liga agora, ou perdemos o ônibus.
How Nem…nem works
Use Nem…nem to negate both elements. It is typically placed before each noun, adjective, or verb it negates. In many cases the first nem follows a negative word like não or ninguém, but it can also stand alone for emphasis:
Ele não gosta nem de café nem de chá.
Ela nem estudou nem trabalhou.
When negation is applied to verbs, retain the personal conjugation and place nem directly before each verb or action phrase for clarity.
When to use each: practical guidelines
Choosing between alternatives: use Ou…ou
Use Ou…ou whenever there is a choice or alternative. It implies that at least one of the options may be true or will happen. Often, context determines whether the alternatives are exclusive (only one can be true) or non-exclusive (more than one could be true):
Quer suco ou água?
Você vai ao cinema ou prefere ficar em casa?
In spoken Brazilian Portuguese, ou can be used alone between two items: café ou chá. When offering choices, the first ou is sometimes omitted.
Rejecting both options: use Nem…nem
Use Nem…nem when you want to deny both things simultaneously. It is stronger than a single negation and emphasizes that neither element applies:
Eu nem quero comida nem bebida agora.
Ele nem respondeu nem apareceu.
Nem often carries an emphatic or colloquial tone in Brazilian Portuguese, especially when used at the start of a sentence to show frustration or surprise.
Negation patterns and placement
With não: combining negation words
Portuguese commonly uses não before verbs to negate a clause. When using Nem…nem, you sometimes see não plus nem, but não is not strictly required with Nem…nem because nem itself expresses negation. Both forms occur, with slight differences in emphasis:
Ele não come nem peixe nem carne. (common, neutral)
Ele nem come nem fala. (more emphatic, colloquial)
If you place não before a verb and you still want to negate two items, keep nem before each item for parallelism.
Pronouns and agreement
Ou…ou and Nem…nem do not change form to agree with gender or number. Instead, the nouns, adjectives, or verbs they connect must agree as usual with the subject. Examples:
Ela pode escolher ou vermelho ou azul.
Eles nem falaram nem ouviram a notícia.
Examples by category: nouns, verbs, adjectives
Nouns
Use the pairs to connect nouns as alternatives or negated items:
Carnes ou legumes? (choice)
Ele não come nem carne nem peixe. (negation)
Verbs
When verbs appear in clauses, maintain the conjugation and place the connectors appropriately:
Ou vamos agora, ou esperamos até amanhã.
Ela nem estuda nem trabalha, fica em casa o dia todo.
Adjectives and adverbs
Adjectives and adverbs can be paired the same way:
O filme foi longo ou chato?
O filme não foi nem longo nem interessante.
Common mistakes and how to avoid them
Overusing não with Nem…nem
Beginners sometimes add não unnecessarily: Não nem gosto. This is ungrammatical. Use either não with a single negative or Nem…nem without não at the start of the clause if you are emphasizing neither thing:
Incorrect: Não nem gosto de sopa.
Correct: Nem gosto de sopa. / Não gosto de sopa nem de caldo.
Confusing ou with ou então or senão
Ou is a simple choice marker. Ou então can mean otherwise or alternatively, and senão often means otherwise or if not. Be careful with translations:
Vamos agora ou depois? = Are we going now or later?
Vai agora ou então vai perder o ônibus? = Go now, otherwise you will miss the bus.
Estude, senão você vai reprovar. = Study, otherwise you will fail.
Using Nem on its own
Nem is often used colloquially to mean not even. In such cases it does not always pair with another nem, but the nuance changes:
Ele nem ligou. = He didn’t even call. (not a paired negation)
Ele nem ligou nem enviou mensagem. = He neither called nor sent a message.
Colloquial usage and regional notes
Informal speech and reduced forms
In spoken Brazilian Portuguese, speakers often drop repeated elements for brevity or rhythm. For Ou…ou, you might hear a single ou standing between two nouns. With Nem…nem, both instances are usually kept for balance, but in fast speech the first nem might be stressed while the second feels lighter.
Emphasis and intonation
Intonation plays a big role. Rising intonation with Ou…ou makes the phrase sound like a question or invitation to choose. Falling intonation with Nem…nem emphasizes finality and exclusion. Learn natural rhythm by listening to Brazilian conversations and media.
More examples in natural contexts
Offering alternatives at a restaurant:
Você quer arroz ou batata?
Eu quero arroz ou batata.
Refusing both options politely:
Desculpe, eu nem bebo álcool nem fumo.
Decision in a meeting:
Ou aprovámos o projeto ou adiamos a decisão para a próxima semana.
Informal complaint:
Ele nem atendeu o telefone nem respondeu a mensagem.
Expressing non-exclusive choice:
Posso trabalhar de casa ou no escritório, depende do dia.
Translation tips for English speakers
Translate Ou…ou as either…or when offering choices. Decide if the options are exclusive—English either often implies exclusivity, while Portuguese ou can be ambiguous; context will clarify. Translate Nem…nem as neither…nor or not…nor. When nem means not even, prefer not even or didn’t even.
Be careful with double negatives: Portuguese allows structures that look like double negatives to English speakers, but they are grammatically correct and often required for emphasis. For example:
Eu nem gosto nem quero esse tipo de música. = I neither like nor want this kind of music.
Useful collocations and verbs often paired
Common verbs and phrases with Nem…nem: gostar, saber, querer, lembrar, falar, ver.
Common contexts with Ou…ou: escolher, decidir, preferir, aceitar, trocar.
Quick reference patterns
Choice between two nouns: Substantivo ou substantivo.
Choice between clauses: Clause, ou clause.
Negation of two nouns: (Não) subst. nem subst.
Negation of two verbs: (Não) verbo nem verbo.
Conclusion
Mastering Ou…ou and Nem…nem helps you give clear choices and strong negation in Brazilian Portuguese. Use Ou…ou for alternatives and Nem…nem to deny both items. Pay attention to placement, intonation, and whether you need não for added emphasis. Listening to native speakers and practicing real sentences will make these pairs feel natural.
