Defining Clauses: Specifying with `que`, `quem`, `onde`
Grammar Rule in 30 Seconds
Use 'que' for things/people, 'quem' for people after prepositions, and 'onde' for physical locations to connect your ideas smoothly.
- Use 'que' as a universal connector for objects or people: 'O livro que eu li.'
- Use 'quem' only for people, usually after a preposition: 'A pessoa com quem falei.'
- Use 'onde' exclusively for physical locations: 'A cidade onde nasci.'
Overview
Ever get that feeling that one clause just isn't enough? You've mentioned a person, a place, or a thing, but you need to say which one specifically. That's where defining relative clauses come in.
They are the grammar tool you use to point a laser beam at a noun and say, "this one, not that other one." Without them, your sentences can be vague. It’s the difference between saying "The man is my teacher" and "The man who is wearing the yellow hat is my teacher." See? Specificity!
These clauses are called orações subordinadas adjetivas restritivas in Portuguese. That's a mouthful, I know. Just think of them as "restricting" clauses.
They restrict the meaning of the noun to a specific instance. And the key thing? No commas!
Adding commas changes the whole meaning, turning it into a non-defining clause (which is a different story for another day).
Defining relative clauses are essential for clear communication. They add necessary information to identify a noun you've mentioned. Imagine you're telling a friend about a series you're binging on Netflix.
You wouldn't just say, "The character is amazing." You'd say, "The character who has the dragon is amazing." That last part, who has the dragon, is a defining relative clause. It's not extra info; it's vital. Without it, your friend has no idea which of the 50 characters you're talking about.
In Portuguese, you'll use specific pronouns like que, quem, onde, and cujo to build these clauses. They act as connectors that link the extra information back to the original noun. Think of them as special hooks.
They grab the noun and attach a descriptive sentence to it. This structure is super common in both spoken and written Portuguese, from WhatsApp messages to formal reports. Mastering it will make your Portuguese sound much more natural and precise.
How This Grammar Works
Eu comprei o livro. (I bought the book.)O livro estava em promoção. (The book was on sale.)O livro que eu comprei estava em promoção. (The book that I bought was on sale.) The pronoun que replaces o livro in the second sentence and connects it seamlessly. The clause que eu comprei defines which book we're talking about. These clauses always follow the noun they modify.Que is the all-purpose workhorse, but sometimes you need a more specialized tool. Onde is strictly for places. Quem is for people, especially after a preposition.cujo is the formal one for showing possession. It's a bit tricky, but it makes you sound incredibly smart when you get it right. It's like knowing when to use a whisk instead of a fork in the kitchen – both can mix, but one does the job much more elegantly.Formation Pattern
A mulher saiu.) - The woman left.
que (that/which/who): for people or things.
quem (who/whom): for people, usually with a preposition.
onde (where): for physical places.
cujo/a/os/as (whose): for possession.
o qual/a qual/os quais/as quais (which/that/who): a more formal version of que.
A mulher...)
A mulher que mora aqui...)
A mulher que mora aqui saiu.)
When To Use It
- To distinguish between items: When you're online shopping and talking to a friend: "Get the shirt
que tem listras(that has stripes), not the plain one." - To identify people: "Minha chefe é a mulher
com quem falei ontem." (My boss is the womanwith whom I spoke yesterday.) - To specify locations: In a travel vlog: "Esta é a praia
onde aprendi a surfar." (This is the beachwhere I learned to surf.) - In professional settings: During a Zoom interview: "O projeto
em que trabalheifoi um sucesso." (The projecton which I workedwas a success.) - Giving directions or instructions: "Use a ferramenta
que está na caixa vermelha." (Use the toolthat is in the red box.)
que is common for learners, and while often understood, learning to use quem, onde, and cujo will elevate your Portuguese from good to great. It shows you have a deeper understanding of the language's structure.Common Mistakes
- 1Using
ondefor non-places: This is a classic. Remember,ondeis for physical locations only. You can't use it for abstract situations.
- ✗
Numa situação onde todos gritam... - ✓
Numa situação em que todos gritam...(In a situation where everyone shouts...)
- 1Forgetting prepositions: If the verb in your relative clause needs a preposition, you must put it before the relative pronoun. This is a huge one!
- ✗
O filme que eu te falei é ótimo. - ✓
O filme de que eu te falei é ótimo.(Because youfalar desomething.)
- 1The dreaded
cujo+ article: Never, ever, ever put an article (o,a,os,as) aftercujo.
- ✗
O autor cujo o livro eu li... - ✓
O autor cujo livro eu li...(The author whose book I read...)
- 1Mixing up
queandquem:Quemis for people, but usually only when there's a preposition. If there's no preposition,queis often the more natural choice, even for people.
- ✓
A pessoa que chegou...(The person who arrived...) - ✓
A pessoa a quem me referi...(The person to whom I referred...)
Contrast With Similar Patterns
- Defining Clauses (the topic here):
- Function: Identify/restrict the noun. Essential information.
- Punctuation: NO commas.
- Example:
Os jogadores que são brasileiros foram convocados.(The players who are Brazilian were called up.) - Meaning: Only the Brazilian players were called up, not all the players.
- Non-Defining Clauses:
- Function: Add extra, non-essential information about a noun that is already specific.
- Punctuation: ALWAYS set off by commas.
- Example:
Os jogadores, que são brasileiros, foram convocados.(The players, who are Brazilian, were called up.) - Meaning: All the players were called up, and by the way, they happen to be Brazilian.
Quick FAQ
Can I just use que for everything?
You can, and people will usually understand you. It's the Swiss Army knife of pronouns. But using onde, quem, and cujo correctly makes you sound more proficient and can be necessary for clarity.
Is o qual really that formal?
In Brazilian Portuguese, yes, it sounds quite formal or written. It's often used to avoid ambiguity or after multi-syllable prepositions (apesar do qual, durante o qual). In day-to-day chat, stick with que.
How do I know if the verb needs a preposition?
This comes down to learning verb valency (regência verbal). When you learn a new verb, learn what prepositions it uses. Think gostar de, falar com, precisar de, referir-se a. It's a slow process, but there are no shortcuts, unfortunately!
So no comma, ever?
For defining relative clauses, correct. No comma before the pronoun. If you add a comma, you're changing it into a non-defining clause with a different meaning. Punctuation is power!

FAQ (8)
In casual Brazilian Portuguese, yes. In formal writing, you should distinguish between 'que', 'quem', and 'onde'.
Because the verb 'falar' requires the preposition 'com'.
Yes, strictly for physical locations.
Use 'que' as a safe default for things and people.
They are similar, but 'o qual' is more formal and helps avoid ambiguity.
No, use 'em que' for time.
No, 'quem' is only for people.
Check the verb. If it's 'falar com', 'gostar de', 'ir a', you need the preposition.
