The word det wears more hats than almost anything else in Swedish. Sometimes it is a real pronoun ("it / that," pointing at a neuter thing — see den and det as Pronouns). But just as often it is an expletive, or placeholder: a grammatically required word that fills a slot without referring to anything. English has the same trick on a smaller scale — the "it" in It's raining and It's nice to travel refers to nothing — but Swedish leans on placeholder det in five distinct structural jobs. This page sets all five side by side, each labelled, so you can identify which job det is doing in any sentence and stop omitting it where it is obligatory.
The principle: Swedish needs the subject slot filled
The reason placeholder det exists at all is a hard rule of Swedish word order: a declarative main clause is verb-second (V2), and the slot before the verb — the fundament — together with the subject slot must be filled. When there is no real subject (weather), or the real subject has been pushed to the back (existentials, extraposition), Swedish plugs the gap with det. It is structural scaffolding, not meaning. Keep that in mind and all five uses below are the same instinct applied to different sentences.
Use 1 — Weather / impersonal det
The most basic placeholder use: verbs of weather, time, and bare states that have no real subject at all. Det fills the empty subject slot.
Det regnar.
It's raining. [WEATHER det] — 'Det' refers to nothing; rain has no subject. The slot just has to be filled.
Det är kallt ute idag.
It's cold outside today. [IMPERSONAL det] — a bare state with no logical subject; 'Det' is pure placeholder.
Det blåser och det börjar bli mörkt.
It's windy and it's getting dark. [WEATHER det, twice] — each clause needs its own placeholder subject.
This is the use closest to English, which also says it's raining. The difference is only that Swedish uses det (neuter "it/that") where English uses it.
Use 2 — Existential / presentational det
Here det introduces something into the discourse — "there is / there are." It fills the subject slot while the real, logical subject (which must be indefinite) waits after the verb. This is a topic in its own right; see Existential Sentences.
Det finns en lösning.
There is a solution. [EXISTENTIAL det] — 'Det' = 'there'; the logical subject 'en lösning' follows the verb. Marks bare existence.
Det kom en man och frågade efter dig.
A man came and asked for you. [PRESENTATIONAL det] — 'Det' holds the slot while the new referent 'en man' is introduced after the verb 'kom'.
Note the difference from Use 1: here det has a job in the information structure — it lets Swedish present brand-new information at the end of the clause, where new information naturally goes. The English equivalent is "there," not "it."
Use 3 — Extraposition placeholder det
This is the use that trips up English speakers most. When the real subject is a whole att-clause or infinitive phrase, Swedish does not usually leave that heavy clause sitting in the subject slot. It moves the clause to the end and parks a placeholder det in the vacated subject position. The det literally holds the seat for the postponed clause. (The dedicated page is Extraposition.)
Det är roligt att resa.
It's fun to travel. [EXTRAPOSITION det] — the real subject is 'att resa' ('to travel'), moved to the end; 'Det' holds the empty subject slot. Literally 'It is fun, to travel.'
Det är synd att du inte kunde komma.
It's a pity you couldn't come. [EXTRAPOSITION det] — 'Det' stands in for the postponed clause 'att du inte kunde komma'.
Det förvånade mig att hon sa ja.
It surprised me that she said yes. [EXTRAPOSITION det] — the att-clause is the logical subject of 'förvånade'; 'Det' fills the slot up front.
You can front the clause instead (Att resa är roligt, "To travel is fun"), and that is grammatical — but it sounds heavier and more formal. The natural default is to extrapose and use placeholder det. What you may not do is drop the det: \Är roligt att resa* has an empty subject slot and is ungrammatical.
Use 4 — Cleft pivot det
A cleft splits one clause into two to spotlight a single element. Swedish builds it as Det är/var X som ... — "It is/was X that ...". The det is the pivot of the focusing frame; it points at nothing, it just launches the construction. (Full treatment on Cleft Sentences.)
Det är Anna som ringde.
It's Anna who called. [CLEFT det] — the plain sentence 'Anna ringde' is split so 'Anna' is spotlighted: 'It is Anna that called'. 'Det' is the cleft pivot, not a referent.
Det var igår som allt hände.
It was yesterday that everything happened. [CLEFT det] — here the time 'igår' is focused. 'Det var ... som ...' is the focusing frame.
Det är dig jag menar.
It's you I mean. [CLEFT det] — 'dig' (object form) is clefted to the front for emphasis.
Clefting is far more common in Swedish than the English "it is … that …" construction, and it is the natural way to put contrastive emphasis on a constituent. The det here is doing focus-structure work, not weather or existence work.
Use 5 — Fundament-filler det in reported speech
Finally, det serves as the opening fundament-filler in impersonal reporting frames — Det sägs att... ("it is said that"), Det heter att..., Det sägs/påstås/visar sig att.... The clause being reported is postponed; det fills the front slot. (This overlaps with extraposition — the reported att-clause is the logical subject — but it is worth its own label because it is a fixed, idiomatic frame.)
Det sägs att han ska sluta.
It is said that he's going to quit. [REPORTED-SPEECH det] — 'Det' opens the impersonal reporting frame; the content 'att han ska sluta' follows. Common in news and gossip alike.
Det visade sig att hela historien var påhittad.
It turned out that the whole story was made up. [REPORTED-SPEECH / extraposition det] — 'Det' fills the slot; the att-clause is the postponed logical subject.
All five side by side
This is the payoff. One word, five structural jobs — read down the table and you have a recognition key for any det you meet:
| Function | Frame | Example | English "it/there"? |
|---|---|---|---|
| Det + verb | Det regnar. | "it" |
| Det finns/kom + indef. subject | Det finns en lösning. | "there" |
| Det är X att-clause | Det är roligt att resa. | "it" |
| Det är X som ... | Det är Anna som ringde. | "it" |
| Det sägs/visar sig att ... | Det sägs att han ska sluta. | "it" |
Why English speakers drop it — and shouldn't
English allows a few subjectless constructions (Raining again, Seems fine) and freely fronts clausal subjects (To travel is fun). Swedish does not tolerate an empty subject slot in a finite main clause — V2 demands something there. So the single biggest det error is omission: leaving out the placeholder where Swedish requires it. Train yourself to ask, for every clause: is the subject slot filled? If the real subject is missing, postponed, or non-existent, the answer is a placeholder det.
Common Mistakes
❌ Regnar idag.
Incorrect — a weather verb still needs its placeholder subject. The subject slot can't be empty in Swedish: 'Det regnar idag'.
✅ Det regnar idag.
It's raining today.
❌ Är roligt att resa.
Incorrect — the extraposed clause leaves the subject slot empty; you must fill it with 'Det': 'Det är roligt att resa'.
✅ Det är roligt att resa.
It's fun to travel.
❌ Finns en lösning. (statement, not a question)
Incorrect as a plain statement — the existential needs front 'Det': 'Det finns en lösning'. (Inversion in a question, 'Finns det en lösning?', is a different structure.)
✅ Det finns en lösning.
There is a solution.
❌ Anna är som ringde. (no cleft pivot)
Incorrect — a cleft needs the 'Det är ... som ...' frame: 'Det är Anna som ringde'. Without the pivot 'Det' the sentence falls apart.
✅ Det är Anna som ringde.
It's Anna who called.
❌ Sägs att han ska sluta.
Incorrect — the impersonal reporting frame opens with 'Det': 'Det sägs att han ska sluta'. The front slot must be filled.
✅ Det sägs att han ska sluta.
It is said that he's going to quit.
Key Takeaways
- det is Swedish's all-purpose placeholder (expletive): it fills a grammatical slot without referring to anything, because a finite main clause (V2) cannot leave the subject slot empty.
- It does five structural jobs: (1) weather/impersonal (Det regnar), (2) existential/presentational (Det finns en lösning; Det kom en man), (3) extraposition holding the slot for a postponed clause (Det är roligt att resa), (4) cleft pivot for focus (Det är Anna som ringde), and (5) reported-speech filler (Det sägs att...).
- English uses "it" for jobs 1, 3, 4, 5 and "there" for job 2 — but it allows omissions and clause-fronting that Swedish does not.
- In nearly all of these the det is obligatory — the single most common error is omitting it (*Regnar, \Är roligt att resa*).
- To parse any det, ask which slot it fills: real referent (true pronoun) or empty/postponed subject (placeholder).

- Existential Sentences (det finns / det är)A2 — How to say 'there is / there are' in Swedish — and why it splits into two constructions English merges into one. Det finns marks pure existence ('is there such a thing?': Det finns en lösning), while det är and presentational verbs mark located presence ('is something here right now?': Det är någon vid dörren / Det står en man där). The dummy subject is det, the real ('logical') subject follows the verb — and it must be INDEFINITE.
- Extraposition and the Anticipatory detB2 — Why Swedish says Det är roligt att resa ('It's fun to travel') rather than putting the heavy att-clause first: a long clausal subject or object is shifted to the end and a placeholder 'det' holds its slot — exactly mirroring English 'it is … to …', except the placeholder is always neuter det, never den.
- Cleft Sentences (Det är ... som)B2 — A cleft splits one sentence into two to spotlight a single element: Det är Anna som ringde ('It's Anna who called'). The frame Det är/var X som ... lets you focus a subject, object, or adverbial for contrast. Swedish reaches for clefts FAR more readily than English (which often just stresses the word), and som is OBLIGATORY in subject clefts even though English drops 'that'.
- den and det for Things (and Sentence det)A2 — Swedish has no single word for 'it': you say den for a singular en-word and det for a singular ett-word — the pronoun follows the noun's gender. But det also has a second life as a dummy subject (Det regnar, Det är kallt) and as a neutral 'it/that' pointing at a whole situation (Det är sant), and there it is ALWAYS det, gender or no gender.
