Swedish future tense: ska, kommer att, or neither

Swedish verbs have no future form. Jag går is I go and I am going, and there is no ending that pushes a verb forward into next week, the way -ade pushes talar back into talade. What Swedish has instead is three ways of talking about what has not happened yet. Choosing between them is not a matter of style. Each one says something the other two do not.

The most common of the three is the one nobody teaches first, and it is the present tense. As soon as a sentence names a time, Swedish leaves the verb alone and lets the time word carry the future on its own. Jag åker imorgon. Bussen går klockan sju. Vi ses på fredag. Not one of those verbs is doing anything a present tense verb does not do, and all three sentences are about something that has not happened.

This is the piece beginners walk straight past. You arrive expecting a future, you meet ska on the first page of the grammar, and from then on every sentence about tomorrow gets a ska in it. Nothing produced that way is wrong. It is heavier than what the person opposite you would have said, and it puts a decision into sentences where nobody was reporting a decision.

The time reference has to be there, or already settled between you. Jag åker on its own means I am leaving now, or I travel, depending on what surrounds it. Add imorgon, i juni, på fredag or om tio minuter and the same three words move into next week without changing shape. Om is worth a line of its own: om tio minuter means in ten minutes from now, and it only ever points forward.

Ska carries a will. Somebody has decided the thing will happen, and most of the time that somebody is the person speaking. Jag ska ringa henne says the call is a decision, already taken and now reported. Vi ska flytta i juni says the move is settled between us. Neither sentence is a weather report about your own life. Both are announcements of something chosen.

Kommer att carries no will at all. It says something is going to happen and stays neutral about who wants it, or whether anybody does. Det kommer att regna. Nobody decided the rain. Kötiden kommer att bli längre, said about a housing queue, is a forecast read off the numbers rather than a plan somebody made.

Put the two on the same sentence and the difference stops being abstract. Jag ska bli lärare says you have decided to be a teacher: you applied, you are training, that is the plan. Jag kommer att bli lärare says it is going to turn out that way. The second is what you say when you are reading the signs, not when you are announcing a choice, and a Swede hears it as a prediction about you rather than a decision by you.

That asymmetry is what makes a wrong choice sound strange rather than merely incorrect. Kommer att with jag as its subject turns your own plans into a forecast about yourself, which lands somewhere between a joke and a shrug. Ska with det and a weather verb hands you the decision about the weather, which nobody claims, so Swedish reads that sentence as something else entirely. What it reads instead gets a section of its own further down.

Here is the mistake that shows up in writing, and it is worth fixing before anything else on this page. After ska, the second verb is a bare infinitive: jag ska gå, hon ska börja, vi ska flytta. After kommer, that same verb needs att in front of it: jag kommer att gå, hon kommer att börja, vi kommer att flytta. Jag ska att gå does not exist in any register of Swedish.

There is a reason, and knowing it saves you memorising an exception. Ska belongs to the modal verbs, the small family that also holds kan, vill, måste, får and bör, and not one of them ever takes att. Kan du komma? Jag vill sova. Du måste fylla i blanketten. Ska is the sixth member of a club you already use daily. Kommer is not in that club. It is an ordinary verb, so an infinitive after it needs the ordinary infinitive marker, the same att as in Det är svårt att förstå.

Inte lands in different places for the same reason. Jag ska inte gå puts the negation straight after ska. Det kommer inte att regna puts it after kommer and in front of att, never behind it. Det kommer att inte regna is wrong, and it is what comes out when kommer att has been learned as one unbreakable block rather than as a verb plus a marker.

Word order needs nothing new from you. Only the conjugated verb counts for second position, so a fronted time word moves the subject and leaves the infinitive parked at the end: Imorgon ska jag ringa Skatteverket. Imorgon kommer det att snöa. That is the V2 rule doing its usual job, and it treats ska and kommer exactly like any other finite verb.

One thing to expect in the room rather than on the page. In speech, the att after kommer very often disappears: det kommer bli kallt, du kommer gilla det. You will hear it constantly and nobody corrects it. Written Swedish keeps att, so write it, and let your ear get used to the version that drops it.

English hands you two futures, and they map onto the Swedish pair almost well enough to be dangerous. Will looks like ska. Going to looks like kommer att. The resemblance holds until the first sentence where it does not, and that sentence usually turns up in week two.

Take a forecast built on will. It will rain tomorrow. There is no decision anywhere in that, and the Swedish that matches it is Det kommer att regna imorgon. Det ska regna imorgon is a real sentence, but it says the forecast said so, which is a claim about a source rather than about the sky. Reaching for ska because the English had will puts a source in your sentence that you never meant to name.

Now take a decision built on going to. I'm going to call her this afternoon. The English is going to, and the Swedish is Jag ska ringa henne i eftermiddag. Jag kommer att ringa henne turns a decision of yours into a prediction about your own behaviour, as though you had watched yourself from a distance and concluded that the call was likely.

English splits on how certain the speaker is and on where the evidence sits. Swedish splits on whether a will is behind the event at all. So the question that resolves a sentence is not which English form you started from. It is who decided this. A person decided it, use ska. Nobody decided it, use kommer att. That one question settles most of what you will want to say before any grammar has to be consulted.

Ska turns up far more often than a future auxiliary would explain, because deciding is something people do out loud and together. A suggestion in Swedish is a ska question. Ska vi ta en fika? Ska vi ses på fredag? An offer is the same question with jag in it: Ska jag hjälpa dig? Ska jag stänga fönstret? Both are asking whose decision this is going to be, which is precisely what ska is for.

The same verb is how you get told what to do, and it is why letters from Swedish authorities are full of it. Du ska fylla i blanketten och skicka in den. Du ska ta med legitimation. It is softer than måste and firmer than bör, and it is the ordinary way an institution states an instruction. Read it as you are to rather than as you will, and half the post that arrives in your first year stops sounding like a threat.

Ska also stands in front of a destination with the verb of movement left out completely. Jag ska hem. Jag ska till tandläkaren på tisdag. Vart ska du? Nothing has gone missing and nothing needs adding. The direction is the whole of the predicate, and this is one of the most common sentence shapes in spoken Swedish, which is why it stops beginners dead the first few times they hear it.

In laws, contracts and older books the same word is spelled skall. It is not a different verb and it does not mean anything the shorter form does not. Modern Swedish writes ska, official prose has largely followed, and you will still meet skall on paper often enough to be glad you recognised it.

One use of ska has nothing to do with the future, and knowing it stops a whole class of sentences from misfiring on you. Ska in front of vara reports something you have been told rather than something you know. Restaurangen ska vara jättebra means the restaurant is supposed to be very good, on somebody else's authority. Han ska vara mycket duktig says people say he is very good, and takes no responsibility for whether he is.

For something already over, the shape is ska ha plus the supinum. Han ska ha flyttat till Norge means he is said to have moved to Norway. Swedish news reporting runs on this construction, because it lets a paper state a claim and attribute it in the same breath, so a sentence like Han ska ha sagt det på mötet reports the accusation without endorsing it.

What tips you off is the verb after ska and the absence of anything decidable. Nobody plans to be good at their job the way one plans a trip, so Han ska vara duktig cannot be a plan and is read as hearsay. Det ska regna imorgon works the same way. Rain is not a decision, so the sentence is understood as passing on the forecast rather than announcing one.

Recognise this one before you use it. Reading it correctly saves you hearing a recommendation as a plan, which is where the misunderstanding usually lands. When you want to say the same thing yourself, jag har hört att does the job with no ambiguity in it at all, and it costs you one extra word.

Write three sentences about your own next seven days, and stop there. One in the present with the time word in it: Jag tvättar på lördag. One with ska, about something you have decided: Jag ska ringa vårdcentralen på måndag. One with kommer att, about something nobody decided: Det kommer att bli kallt i helgen. Three sentences, and the whole system has been used once.

Then check the two things that go wrong on paper. Is there an att after kommer? Is there no att after ska? Almost every future sentence a learner writes fails on one of those, and both are visible without knowing a word more grammar than you have just read.

What this buys you is the tense you need to make a plan out loud, which is most of what a first year in Sweden consists of. Booking, agreeing, saying when you can come. A sentence that arrives whole does not open the half second gap in which the other person switches, and that switch is what ends most beginners' Swedish. The other end of the timeline runs on its own pair of rules, and jag åt against jag har ätit is ten more minutes. If your SFI place is still months away, these are the cheapest hours of Swedish you will ever buy.
