Pronomes relativos: o sistema completo
Lesson 25 introduced the four basic relatives. At B2 the focus shifts to PRECISION: which one to use after which preposition, when cujo is mandatory and how to dodge it, when formal o qual / a qual wins over plain que, and how the relative interacts with clitic placement (próclise, lesson 31). The five players: que (everything, but only after short prepositions), quem (people after prepositions), cujo (possessive — agrees with the thing owned), o qual (formal alternative, agrees), onde (places, increasingly time too).
que — the workhorse, with one limitation
que handles most relative clauses, referring to people or things, as subject or object. O homem que mora aqui (subject), o livro que comprei (object). After SHORT prepositions (one syllable), que still works for things: a casa em que vivo, o assunto de que falamos, a razão por que vim. After people, EP prefers quem in this slot (see below). Two cautions: (1) que with a/de/em/com/por for things is clean; (2) after multi-syllable prepositions (durante, mediante, através de, dentro de), formal Portuguese reaches for o qual instead because que sounds awkward. A janela através da qual via o jardim ≫ a janela através de que via o jardim. As always with que, próclise is triggered (lesson 31): a pessoa que me viu.
quem — people after prepositions
quem is reserved for PEOPLE and almost always appears after a preposition. A pessoa COM quem trabalho, o amigo A quem dei o livro, a senhora DE quem falei, o homem PARA quem trabalhas, os colegas SEM quem não consigo trabalhar. quem is invariable — singular and plural use the same form (os amigos com quem fui). Without a preposition, default to que for people: o homem que vi (NOT o homem quem vi). One literary use exists without a preposition — quem as 'the one who': Quem cala consente = Silence implies consent. In modern indirect questions and free relatives this quem stays alive, but in standard relative-clause use it pairs with a preposition.
cujo — the possessive relative
cujo = 'whose' / 'of which' — agrees with the THING OWNED in gender and number. Forms: cujo (m.sg.), cuja (f.sg.), cujos (m.pl.), cujas (f.pl.). O escritor cujo livro li (the writer whose book I read — book is m.sg., so cujo). A rapariga cuja mãe é médica (whose mother — mother is f.sg., so cuja). As pessoas cujos filhos estudam aqui (whose children — children m.pl., so cujos). A casa cujas janelas estão pintadas de azul. Three rules: (1) NO article between cujo and the noun (NOT cujo o livro). (2) cujo can take a preposition before it: o autor a cujo livro me referi = the author to whose book I referred. (3) cujo is bookish — fine in writing, journalism, formal speech; rare in casual conversation, where speakers paraphrase: a rapariga que tem a mãe médica. EP keeps cujo alive more than BR, but it's optional even there. At B2 you must recognize and produce it in writing.
o qual / a qual / os quais / as quais — the formal alternative
o qual is a formal/written alternative to que, and the go-to choice after multi-syllable prepositions. It AGREES with the antecedent: o qual (m.sg.), a qual (f.sg.), os quais (m.pl.), as quais (f.pl.). A casa NA QUAL vivi (the house in which I lived). O projeto SOBRE O QUAL trabalho (the project on which I'm working). Os documentos AOS QUAIS me referi (the documents to which I referred). A janela ATRAVÉS DA QUAL = the window through which. The contractions: a + o qual = ao qual, a + a qual = à qual, de + o qual = do qual, em + o qual = no qual, etc. Two big jobs for o qual: (1) avoiding ambiguity when que could refer to several antecedents; (2) following multi-syllable prepositions (durante, mediante, através de, graças a, apesar de) where que sounds wrong. In speech, EP often substitutes plain que anyway — o qual is a written-register tool.
onde — places, and (loosely) time
onde = where, anchored to a place. A cidade onde nasci, o café onde nos encontrámos. With motion to/from, EP distinguishes: aonde (to where) for goal, donde / de onde (from where) for source — but everyday speech often blurs all three into plain onde. A cidade aonde vou vs. a cidade onde vou are both heard. Onde for time (o dia onde te conheci) is gaining ground in casual speech but textbook style still wants em que or quando for time: o dia em que te conheci = the day I met you. After prepositions, onde is unusual; instead, use em que for things or o qual for formal: o sítio em que vivo alongside o sítio onde vivo.
Restrictive vs. non-restrictive — comma matters
Like English, Portuguese distinguishes RESTRICTIVE (defining) and NON-RESTRICTIVE (extra-info) relative clauses by punctuation. Restrictive: no comma, identifies which one — os alunos que estudaram passaram = the students who studied passed (only those who studied). Non-restrictive: commas, adds extra info — os alunos, que estudaram, passaram = the students, who [all] studied, passed (all of them, by the way). The pronoun choice is the same; the comma changes the meaning. In non-restrictive clauses, o qual is somewhat preferred over que in formal writing for clarity: o meu pai, o qual mora em Coimbra, está bem. In speech, intonation does the work and que dominates either way.
Próclise inside relative clauses
Every relative pronoun (que, quem, o qual, cujo, onde) triggers PRÓCLISE on any clitic in its clause (lesson 31). A pessoa que ME viu (NOT que viu-me). O amigo a quem TE apresentei (NOT apresentei-te). O lugar onde NOS conhecemos. A casa cujas janelas SE abrem para o jardim. This is one of the most common B2 errors — students who've internalized ênclise as the EP default forget that any subordinator pulls the pronoun forward. Fix: train yourself to scan for relative pronouns before placing the clitic. In compound tenses, the clitic still goes before the auxiliary: a pessoa que ME tinha visto (NOT tinha-me visto).
