Pronomes relativos: o sistema completo
Lesson 25 handed you the four basic relatives. At B2 the job changes from 'which word' to precision: which pronoun after which preposition, when cujo is the only honest option and how Brazilians dodge it anyway, when o qual earns its place over plain que, and where the object pronoun sits once a relative clause opens. Five players. que does almost everything, with one limitation. quem takes people after a preposition. cujo is 'whose', and it agrees with the thing owned. o qual is the formal alternative that agrees in gender and number. onde is for places, and — loosely, in speech — for time.
que — the workhorse, with one limitation
que handles most relative clauses you'll ever build: people or things, subject or object, never changing shape. Subject: O homem que mora aqui é meu tio. Object: O livro que eu li ontem é ótimo. After a short preposition it still works when the antecedent is a thing: a casa em que eu moro, o assunto de que a gente falou, o motivo por que eu liguei. Here's the limitation: after a long preposition — através de, dentro de, diante de, por meio de, graças a — que sounds cramped and careful Portuguese switches to o qual. A janela através da qual dava para ver o mar is right; a janela através de que dava para ver o mar is not something anyone writes. One more thing que does automatically: it pulls any object pronoun to the front of its verb. A pessoa que me viu, never a pessoa que viu-me — and that's true on both sides of the ocean.
quem — people after prepositions
quem is for PEOPLE, and in practice it shows up right behind a preposition: a pessoa com quem eu trabalho, o amigo a quem eu dei o livro, a moça de quem eu te falei, o chefe para quem eu trabalhava, os colegas sem quem eu não consigo trabalhar. It never changes shape — singular and plural share one form: os amigos com quem eu fui. In Brazilian speech para shrinks to pra, and quem comes along: o amigo pra quem eu dei o livro. Without a preposition, go back to que: o homem que eu vi, not o homem quem eu vi. There is one preposition-free quem, the one that means 'whoever' and heads its own clause — the proverbs live there: Quem cala consente, Quem avisa amigo é. That quem is alive and well; the relative-clause one wants its preposition.
cujo — the possessive relative
cujo means 'whose', and the trap is famous: it agrees with the thing OWNED, not with the owner. Four forms: cujo (m. sg.), cuja (f. sg.), cujos (m. pl.), cujas (f. pl.). O escritor cujo livro eu li — livro is masculine singular, so cujo, even though the writer might be a woman. A menina cuja mãe é médica — mãe is feminine. As pessoas cujos filhos estudam aqui. A casa cujas janelas estão abertas. Three rules to hold on to. (1) No article between cujo and its noun: cujo o livro is a mistake. (2) A preposition can sit in front of it: o autor a cujo livro eu me referi. (3) It's bookish — and in Brazil, notably more bookish than in Portugal. Brazilian speech rebuilds the sentence rather than reach for it: o escritor que escreveu aquele livro, or the frankly non-standard o escritor que eu li o livro dele, which you'll hear constantly and shouldn't copy. At B2 you recognize cujo everywhere and produce it in writing.
o qual / a qual / os quais / as quais — the formal alternative
o qual is the formal stand-in for que, and unlike que it agrees with what it points at: o qual, a qual, os quais, as quais. It contracts with a preposition the way any article does: a plus o qual gives ao qual, a plus a qual gives à qual, de plus o qual gives do qual, em plus a qual gives na qual, por plus o qual gives pelo qual. A casa na qual eu morei foi vendida. O projeto sobre o qual eu trabalho é novo. Esse é o motivo pelo qual eu liguei. It earns its keep in two situations. First, after those long prepositions where que won't fit: através da qual, por meio do qual, graças ao qual. Second, when a sentence has two possible antecedents and que would leave the reader guessing — the agreement on o qual points straight at the right one. Registers that love it: contracts, journalism, academic writing. In conversation Brazilians say que and keep walking.
onde — places, and (loosely) time
onde points at a place: a cidade onde eu nasci, a padaria onde a gente se conheceu. Careful writing splits it by direction — aonde for motion toward (a cidade aonde a gente vai) and de onde for origin (a cidade de onde eu venho) — while everyday Brazilian speech flattens all three into plain onde. Time is the other loose edge. Speech says o dia onde eu te conheci and even o dia que eu te conheci; careful Portuguese wants em que: o dia em que eu te conheci. And after a preposition, onde steps aside: use em que for things, o qual when you want the formal register — o lugar em que eu moro, o lugar no qual eu moro, both alongside o lugar onde eu moro.
Restrictive vs. non-restrictive — comma matters
Portuguese draws the same line English does, and it draws it with commas. Restrictive, no commas: Os alunos que estudaram passaram = the students who studied passed — only those. Non-restrictive, commas on both sides: Os alunos, que estudaram, passaram = the students, who had all studied, passed — all of them, and the studying is extra information. The pronoun doesn't change; the punctuation carries the whole meaning, so a stray comma can rewrite your sentence. In formal writing, non-restrictive clauses often prefer o qual for clarity: Meu pai, o qual mora em Curitiba, está bem. In speech, intonation does that work and que wins either way.
Próclise inside relative clauses
Every relative — que, quem, o qual, cujo, onde — puts any object pronoun in front of the verb, the placement grammars call próclise. In Brazil that's where you were already putting it, so this is a rule you get for free: a pessoa que me viu, o amigo a quem eu te apresentei, o lugar onde a gente se conheceu, a casa cujas janelas se abrem para o mar. What matters is knowing the rule exists, because the hooked-on-the-end shape that European Portuguese uses in main clauses — viu-me — is wrong inside a relative clause there too. In compound tenses Brazil slips the pronoun between the auxiliary and the participle: a pessoa que tinha me visto. Books also allow que me tinha visto, and both are correct; only que tinha visto-me is out. Last, a spoken habit worth recognizing and not copying: Brazilians often drop the relative pronoun's job onto a leftover ele or ela — o cara que eu vi ele ontem. Non-standard, extremely common, and a good ear-training target.
