Beslutet kom idag.

The basic dictionary form is beslut. It is a neuter noun, so you say ett beslut for a decision.

In this sentence, beslutet is the definite singular form: the decision.

A useful mini-paradigm is:

• ett beslut = a decision
• beslutet = the decision
• beslut = decisions
• besluten = the decisions

The ending -et is the definite article ending for many ett nouns. It works like English the.

So:

• beslut = decision
• beslutet = the decision

In Swedish, the is often attached to the end of the noun instead of being a separate word.

Because Swedish usually expresses definiteness with a suffix on the noun.

So English the decision is often just one word in Swedish: beslutet.

You only get a separate definite word as well in certain structures, especially when there is an adjective:

• beslutet = the decision
• det viktiga beslutet = the important decision

So in your sentence, beslutet by itself is completely normal.

Kom is the past tense of komma, which means to come.

Forms:

• komma = to come
• kommer = comes / is coming
• kom = came
• har kommit = has come

So Beslutet kom idag uses the simple past.

In Swedish, komma is used quite naturally for things that arrive, come in, or be received/made known, not just for people physically coming somewhere.

So Beslutet kom idag is idiomatic Swedish. It can suggest that the decision arrived, was delivered, or was announced today, depending on context.

Swedish uses komma similarly with things like:

• Brevet kom igår = the letter came/arrived yesterday
• Pengarna kom idag = the money came/arrived today
• Svaret kom sent = the answer came late

Yes. Idag kom beslutet is also correct.

The difference is mainly emphasis:

• Beslutet kom idag puts the topic first: the decision
• Idag kom beslutet puts the time first: today

Both are natural. Swedish often changes word order to highlight different parts of the sentence.

Because Swedish main clauses follow the V2 rule: the finite verb usually comes in the second position.

So:

• Beslutet kom idag
• Idag kom beslutet

In both sentences, the verb kom is still second.

This is why Swedish does not say:

• Idag beslutet kom

That word order sounds wrong in a normal main clause.

Yes, you can, but the nuance is a bit different.

• Beslutet kom idag = simple past; a straightforward report of what happened
• Beslutet har kommit idag = present perfect; focuses more on the result or on the fact that this has happened within today, which is still an unfinished time period

Because idag refers to a time period that may still be ongoing, Swedish can use either form depending on context.

In many everyday situations, Beslutet kom idag is a very natural, neutral way to say it.

A rough guide is:

beh-SLOO-tet kom ee-DAHG

A few notes:

• beslutet has the stress on the second syllable: be-SLU-tet
• kom is short and simple
• idag has stress on the second syllable: i-DAG

The exact vowels are more Swedish than English, of course, but that rough guide can help you get started.
