By this point you have met the two engines of Swedish word order: V2, which keeps the finite verb in second position in a main clause, and BIFF, which governs subordinate clauses (subject before verb, inte before the verb). Everything on the "Complex Grammar" pages is built from those two engines. This overview maps the landscape and sends you to the detail pages — and it makes one promise up front that should change how you approach the whole group.
The one idea: no new word-order rules
Here is the liberating fact. Nearly every "complex" construction in Swedish is just embedding or fronting that reuses the V2/BIFF machinery you already have. A relative clause is a subordinate clause (BIFF) hung on a noun. A conditional is a subordinate om-clause (BIFF) plus a main clause that inverts (V2) when the condition is fronted. Reported speech is an att-clause (BIFF) under a verb of saying. A cleft sentence is det är ... som ... — a main clause (V2) plus a relative clause (BIFF). The pieces are old; only the combinations are new.
This means the difficulty here is combinatorial, not novel. You are not learning a fresh set of rules for each construction. You are learning which clause type goes where and what fills the first slot — and then the word order falls out of rules you already trust. Learners who treat each construction as a brand-new system get overwhelmed; learners who ask "which is the main clause, which is subordinate, and what's been fronted?" find the answers almost write themselves.
The landscape
Here is the territory, with one teaser apiece. Each links to its full page.
Relative clauses
A description hooked onto a noun with som ("who/which/that"). It is a subordinate clause, so BIFF order applies inside it.
Mannen som bor här heter Olof.
The man who lives here is called Olof. 'som bor här' is a relative clause — a BIFF subordinate clause attached to 'mannen'.
The basics live on Relative Clauses; prepositions, vars ("whose") and the clause-referring vilket ("which") on Relatives with Prepositions and vars/vilket.
Conditionals
An om-clause ("if") stating a condition, plus a consequence. Real conditions use ordinary tenses; counterfactual ones use the past and skulle/vore.
Om det regnar stannar vi hemma.
If it rains, we'll stay home. Fronted om-clause (BIFF) + inverted main clause (V2).
The full system — real vs. counterfactual, tense backshift, skulle — is on Conditionals.
Reported (indirect) speech
Embedding what someone said under a verb of saying, with att ("that"). The reported part becomes a subordinate clause.
Hon sa att hon var trött.
She said (that) she was tired. Direct 'Jag är trött' becomes an att-clause; note the backshift är → var.
Tense backshift, the att-drop, and reported questions (om, vad, när) are covered on Reported Speech.
Comparison structures
The full apparatus of comparing — än ("than"), lika ... som ("as ... as"), and the correlative ju ... desto ("the more ... the more") — combines comparatives with subordinate and main clauses.
Ju mer jag läser, desto mer förstår jag.
The more I read, the more I understand. The ju-clause is subordinate; the desto-clause is a main clause that inverts.
This sits in the Conjunctions group on Comparison Conjunctions, because the linking words are the heart of it.
Information-structure devices
Swedish, like English, lets you repackage the same content to spotlight a particular part. The cleft (det är X som ..., "it is X that ...") foregrounds one element; extraposition with a placeholder det shifts a heavy clause to the end. These do not change what is said, only what is in focus.
Det var Anna som ringde, inte Erik.
It was Anna who called, not Erik. A cleft: the main clause 'det var Anna' (V2) + relative 'som ringde' (BIFF), spotlighting Anna.
Det är synd att du inte kan komma.
It's a shame (that) you can't come. Extraposition: placeholder 'det' holds the subject slot; the real subject is the att-clause at the end.
Clefts and presentational/existential det are drilled in the Syntax group: Cleft Sentences and Existential det.
Non-finite constructions
Constructions built on the infinitive and participles rather than a tensed verb — att-infinitives ("to do"), present and past participles used as reduced clauses. These let you compress a whole clause into a phrase.
Hon gick därifrån utan att säga något.
She left without saying anything. 'utan att säga något' is a non-finite att-infinitive phrase doing the work of a clause.
These draw on the Infinitive and the participle pages.
How to use this group
Read Relative Clauses first — it is the most frequent construction and the clearest demonstration of "BIFF, just attached to a noun." Then Conditionals and Reported Speech, which both lean on tense and on the V2/BIFF split. Treat the information-structure pages as polish: they are how you sound natural and emphatic once the core is solid.
Common Mistakes
❌ Treating each construction as a new word-order system to memorise.
Wrong mindset — relative clauses, conditionals and reported speech all reuse BIFF; clefts and conditionals reuse V2. Learn the recombination, not a new rule.
✅ Mannen som inte bor här ... / Om det regnar, stannar vi hemma.
Both fall out of rules you know: BIFF puts 'inte' before the verb inside the relative; V2 inverts the main clause after a fronted om-clause.
❌ Hon sa att hon är trött. (reporting a past statement)
Incorrect in careful Swedish — reported speech backshifts the tense after a past reporting verb: är → var.
✅ Hon sa att hon var trött.
She said she was tired.
❌ Det var Anna vilket ringde.
Incorrect — a cleft uses 'som' for the relative on a noun (Anna), not 'vilket'. 'vilket' is only for a whole-clause antecedent.
✅ Det var Anna som ringde.
It was Anna who called.
Key Takeaways
- The "complex" constructions are recombinations, not new rules: main clauses still obey V2, subordinate clauses still obey BIFF, and fronting still inverts the main verb.
- For any construction, ask: which clause is main (V2), which is subordinate (BIFF), and what is fronted? The word order follows.
- The group splits into: relative clauses, conditionals, reported speech, comparison structures, information-structure devices (clefts, extraposition) and non-finite constructions.
- Word order from the Syntax group is the prerequisite for everything here — if V2 and BIFF feel shaky, revisit them before going further.

- Relative ClausesB1 — How to build a relative clause in Swedish: noun + som + a subordinate (BIFF) clause — mannen som bor här. The rule English speakers trip on is that som can be dropped only when it is the OBJECT (boken jag läste), never when it is the SUBJECT (kvinnan som ringde), the reverse of English instinct. Because the clause is subordinate, inte and other adverbs sit BEFORE the verb inside it (boken som jag inte har läst). Plus restrictive vs. non-restrictive (comma) relatives.
- Conditionals: OverviewB1 — The map of Swedish 'if' sentences: real conditionals (om + present), present counterfactuals (om + past tense, skulle + infinitive), and past counterfactuals (om + pluperfect, skulle ha + supine) — and the one rule English speakers must not over-apply: Swedish, like English, uses the PAST tense to mark unreality in the present.
- Reported (Indirect) SpeechB2 — Turning someone's words into a report: the att-clause, the tense backshift in past reports (present to preteritum, perfect to pluperfect), pronoun and deixis shifts (jag to hon, här to där, imorgon to dagen efter), and the de-inversion that turns a question into a subordinate clause (var jag bodde, not var bodde jag).
- Swedish Word Order: OverviewA1 — Swedish syntax rests on two pillars: V2 in main clauses (the finite verb is ALWAYS the second element, so fronting anything pushes the subject after the verb), and the BIFF rule in subordinate clauses (where sentence adverbs like 'inte' come BEFORE the verb instead). Verb placement, not case, carries the grammar — and this one system explains nearly every word-order 'oddity' that trips up English speakers.
