Jag måste ordna allt före mötet i kväll.

In a normal full sentence, Swedish usually includes the subject, so jag måste = I must / I have to.

You can leave out the subject in some informal contexts, like notes or messages, but in standard Swedish a complete sentence normally keeps it:

• Jag måste ordna allt. = I have to sort everything out.
• Informal note style: Måste ordna allt. = Have to sort everything out.

So here, jag is simply the subject I.

Måste means must or have to. It expresses necessity or obligation.

So:

• Jag måste ordna allt = I must / I have to arrange everything

A useful thing to know is that måste is the present tense form of the modal verb måste in modern usage. Unlike English, Swedish does not use to after it.

Examples:

• Jag måste gå nu. = I have to go now.
• Vi måste prata. = We need to talk.

After modal verbs in Swedish, the main verb normally comes in the infinitive without att.

So:

• Jag måste ordna allt.
• Hon kan komma.
• Vi vill äta.

Not:

• Jag måste att ordna allt. ❌

This is similar to English, where we say must arrange, not must to arrange.

Ordna is a very useful verb with a broad meaning. Depending on context, it can mean:

• arrange
• organize
• sort out
• fix

In this sentence, ordna allt most naturally means something like:

• arrange everything
• sort everything out
• get everything ready

The exact English translation depends on context, but the Swedish verb itself is very common and flexible.

Both allt and allting can mean everything.

• allt is very common and often more neutral or compact
• allting can sound a little fuller or more emphatic, depending on context

So both of these work:

• Jag måste ordna allt.
• Jag måste ordna allting.

In many situations, the difference is small. Here, allt is perfectly natural.

Because mötet means the meeting.

The base form is:

• ett möte = a meeting

The definite form is:

• mötet = the meeting

So:

• före mötet = before the meeting

Swedish often puts the definite article as an ending on the noun, instead of using a separate word like the.

Compare:

• ett hus = a house
• huset = the house

Both can often mean before, but they are not always used in exactly the same way.

In this sentence, före is used before a noun phrase:

• före mötet = before the meeting

That is very natural.

Innan is very often used before a clause:

• innan mötet börjar = before the meeting starts

You may also hear innan mötet in everyday Swedish, but före mötet is especially straightforward and standard when followed by a noun.

A simple learner rule:

• före + noun
• innan + clause

Even though real usage can overlap.

Yes, both i kväll and ikväll are used.

They both mean this evening / tonight, and in many cases the difference is small or nonexistent for learners.

In this sentence:

• i kväll = tonight / this evening

You may also see:

• ikväll

Swedish has several time expressions like this:

• i dag / idag
• i morgon / imorgon
• i kväll / ikväll

The separated spelling in your sentence is completely normal.

Here it means tonight / this evening, referring to the coming evening in relation to the speaker.

So:

• mötet i kväll = the meeting tonight / the meeting this evening

In context, it points to a specific evening meeting, not just evenings in general.

In this sentence, the most natural reading is that it belongs with mötet:

• före mötet i kväll = before the meeting tonight

So the idea is:

• There is a meeting tonight.
• I have to get everything arranged before that meeting.

A learner might wonder whether it could mean:

• I have to arrange everything tonight before the meeting

But that is not the most natural interpretation here. If Swedish wanted to emphasize tonight as the time for arranging things, it would likely be phrased differently.

Because that is a very normal Swedish word order.

The sentence structure is:

• Jag = subject
• måste = finite verb
• ordna allt = infinitive verb phrase + object
• före mötet i kväll = time phrase

Swedish often places adverbials like time expressions later in the sentence, especially in straightforward statements.

But you can move the time phrase to the front for emphasis:

• Före mötet i kväll måste jag ordna allt.

That still means the same thing, but the emphasis shifts slightly toward the deadline.

It is grammatically present, but the meaning points to something that needs to happen before a future event.

That is very common in Swedish. The present tense can be used when the future is clear from context.

So:

• Jag måste ordna allt före mötet i kväll.

means something like:

• I have to get everything sorted out before the meeting tonight.

The future sense comes from i kväll and from the meaning of måste, not from a special future tense form.

A careful approximate pronunciation is:

yahg MUS-teh ORD-na alt FUR-eh MUR-teht ee kvell

A few notes:

• Jag often sounds closer to yahg or even ya in casual speech
• måste has stress on the first syllable
• ordna also has stress on the first syllable
• mötet has a rounded vowel that may be difficult for English speakers
• kväll has the kv sound at the start, roughly like kvell

You do not need a perfect English-style spelling of the sounds, but it helps to notice where the stress falls:

• JAG måste ORDNA allt före MÖTET i KVÄLL

Yes. Fixa is a very common everyday verb meaning fix, sort out, or take care of.

So:

• Jag måste fixa allt före mötet i kväll.

is natural and common.

Compared with ordna:

• ordna can sound a bit more like arrange / organize
• fixa can sound a bit more informal and general

Both are very useful, and which one sounds best depends on context.
