Purpose answers what for? — the goal you act toward (I'm saving in order to travel). Result answers with what consequence? — what actually followed (it rained so much that we got soaked). Swedish expresses both with two small connectors, för att and så att, and the difficulty is that each one is overloaded. för att means "in order to" in one construction and "because" in another, depending entirely on whether an infinitive or a finite clause follows. så att can mean purpose or result, told apart by the verb. This page takes the four uses one at a time and gives you the concrete signal that disambiguates each, so you never have to guess which reading is meant.
för att + infinitive — purpose ("in order to")
The core purpose construction is för att + infinitive. It expresses the goal of an action, and it requires that the subject of the purpose is the same as the subject of the main clause — one person, acting toward their own goal. There is no second subject; the infinitive carries no person of its own.
Jag sparar för att resa jorden runt.
I'm saving in order to travel around the world. 'för att' + the infinitive 'resa'. Same subject ('jag') does both the saving and the travelling.
Hon ringde för att boka tid hos tandläkaren.
She called in order to book an appointment at the dentist. The purpose of calling, expressed with 'för att' + infinitive 'boka'.
Vi tränar varje dag för att bli starkare.
We train every day in order to get stronger. Shared subject 'vi'; the goal follows 'för att' as an infinitive.
The infinitive after för att is the bare verb stem form (resa, boka, bli) — no att of its own beyond the att that is part of för att. This is the construction English renders as "in order to," "(so as) to," or just plain "to" (I'm saving to travel).
för att + finite clause — "because" (a different word!)
Now the trap. The same words för att can introduce a finite clause (one with its own subject and a conjugated verb) — and there the meaning is "because." It is no longer purpose at all; it answers why? in the sense of cause, not goal. The signal is the finite verb with its own subject: if what follows för att is a full clause (subject + tensed verb), read it as "because."
Jag stannade hemma för att jag var sjuk.
I stayed home because I was sick. 'för att' + finite clause ('jag var sjuk') = 'because'. Note the second subject 'jag' and the tensed verb 'var'.
Hon log för att hon var nöjd.
She smiled because she was pleased. A finite clause follows, so 'för att' = 'because' — a cause, not a goal.
Vi åkte tidigt för att vädret var dåligt.
We left early because the weather was bad. 'för att vädret var dåligt' is a finite clause: this is the 'because' reading.
So the whole distinction rides on what follows: an infinitive (no second subject) → för att = "in order to" (purpose); a finite clause (own subject + tensed verb) → för att = "because" (cause). Same two words, two opposite functions. (As a "because" word, för att competes with eftersom and därför att; the choice among them is its own topic — see eftersom vs därför.)
så att — purpose with a different subject (modal signal)
When the goal involves a different subject — you do something so that someone else can do something — you can't use the shared-subject för att + infinitive. You switch to så att + a finite clause. In the purpose reading, the clause typically contains a modal verb — kan ("can"), ska ("shall/will"), skulle ("would") — because a purpose is about enabling or intending a possibility, not reporting a fact.
Jag tänder lampan så att du kan se.
I'm turning on the lamp so that you can see. Purpose with a DIFFERENT subject ('du'); the modal 'kan' signals the purpose reading: enabling you to see.
Hon talar långsamt så att alla ska förstå.
She speaks slowly so that everyone will understand. 'ska' marks intended purpose: the goal is everyone understanding.
Vi lämnade i god tid så att vi inte skulle missa tåget.
We left in good time so that we wouldn't miss the train. The modal 'skulle' + 'inte' (BIFF order, before the verb) signals purpose.
The presence of a modal (kan/ska/skulle) is your best clue that så att is doing purpose ("in order that") rather than result. The clause after så att is subordinate, so it follows BIFF order — note inte before skulle... missa in the third example.
så att — result ("with the result that")
The same så att also expresses result: not the goal you aimed at, but the consequence that actually followed. Here the clause usually has a plain, non-modal verb in the past or present — it reports something that genuinely happened, not something merely intended. It rained so much *that we got soaked* — the soaking is a real outcome, not a purpose.
Det regnade så att vi blev blöta.
It rained so that we got soaked. RESULT: the plain past verb 'blev' (no modal) reports a real consequence, not a goal — nobody intended the soaking.
Han skrek så att hela huset vaknade.
He shouted so that the whole house woke up. 'vaknade' is a plain past — the waking is the actual result of the shouting.
Hon arbetade så hårt att hon blev sjuk.
She worked so hard that she got sick. With an adjective/adverb, the pattern is 'så + [hård] + att' — and the result ('blev sjuk') is plainly factual.
The contrast with purpose is exactly the modal vs plain-verb signal: Jag tänder lampan så att du *kan se (modal → purpose) versus Det regnade så att vi **blev blöta (plain past → result). Same connector; the verb form tips you off. When the result reading is meant, you'll also often see the stressed pattern *så + adjective/adverb + att (så hårt att, så mycket att), which has no purpose reading at all.
Common Mistakes
❌ Jag sparar för att jag reser jorden runt. (meaning 'in order to travel')
Incorrect for the purpose meaning — a finite clause makes 'för att' = 'because'. For 'in order to', use an infinitive: 'för att resa'.
✅ Jag sparar för att resa jorden runt.
I'm saving in order to travel around the world.
❌ Jag tänder lampan för att du kan se. (meaning 'so that you can see')
Incorrect — purpose with a DIFFERENT subject needs 'så att', not 'för att'. ('för att du kan se' would read as 'because you can see'.)
✅ Jag tänder lampan så att du kan se.
I'm turning on the lamp so that you can see.
❌ Hon talar långsamt så att alla förstår inte fel.
Incorrect word order — inside the 'så att'-clause 'inte' comes BEFORE the verb (BIFF): 'så att alla inte förstår fel'.
✅ Hon talar långsamt så att alla inte förstår fel.
She speaks slowly so that everyone doesn't misunderstand.
❌ Det regnade så att vi skulle bli blöta. (meaning the real result)
Incorrect for a real result — the modal 'skulle' forces a purpose/intention reading. A plain consequence takes a plain past: 'blev blöta'.
✅ Det regnade så att vi blev blöta.
It rained so that we got soaked.
❌ Hon ringde för att att boka tid.
Incorrect — only one 'att'. 'för att' already contains the 'att'; the infinitive follows directly: 'för att boka'.
✅ Hon ringde för att boka tid.
She called in order to book an appointment.
Key Takeaways
- för att + infinitive = "in order to" (purpose, shared subject): Jag sparar för att resa.
- för att + finite clause = "because" (cause): Jag stannade hemma för att jag var sjuk. Same two words — the infinitive-vs-finite-clause test decides the meaning every time.
- så att handles purpose with a different subject, usually flagged by a modal (kan/ska/skulle): Jag tänder lampan så att du kan se.
- så att also expresses result, flagged by a plain (non-modal) verb, often after så + adjective/adverb: Det regnade så att vi blev blöta. Modal → purpose; plain past → result.
- The clause after så att is subordinate, so it follows BIFF order — inte goes before the verb.

- Non-Finite Constructions (att + infinitive, för att)B2 — How Swedish builds subordinate ideas without a finite verb: the infinitive marker att (Det är svårt att lära sig svenska), the purpose clause för att + infinitive ('in order to'), and the genom att / utan att / istället för att family — plus the trap that för att means 'in order to' with an infinitive but 'because' with a finite verb.
- Subordinating Conjunctions (att, om, när, eftersom)B1 — The words that open a subordinate clause and force it into BIFF order: att (that), om (if/whether), när (when), då (when/since), eftersom and därför att (because), fast/fastän (although), medan (while), innan (before), sedan (after/since), så att (so that). All of them push the sentence adverb — especially 'inte' — to BEFORE the finite verb. Two notorious pairs to get right: när vs då, and the subordinator därför att (because, BIFF) vs the adverb därför (therefore, main-clause inversion).
- Clause Linking: Coordination vs SubordinationB1 — There are exactly two ways to glue clauses together in Swedish, and the choice leaves a VISIBLE fingerprint on word order. Coordination (och, men, eller, så, för) joins EQUAL clauses and each one keeps plain main-clause V2 order. Subordination (att, om, när, eftersom, fast) makes one clause DEPENDENT, switching it to BIFF order — and that whole subordinate clause can be fronted into the main clause's first slot, forcing the main verb to invert. So clause-linking and word order are the same topic seen from two angles.
- eftersom vs därför (att) (because/therefore)B1 — Three words that look related but point in opposite causal directions. eftersom and därför att both mean 'because' and introduce a REASON in a subordinate clause (BIFF order). därför means 'therefore / so' — it introduces a RESULT, is an adverb, and triggers V2 inversion when it opens the sentence. därför att (because) and därför (therefore) differ by one word but take opposite word order and aim opposite ways along the cause-and-effect arrow.
