Dagskráin fyrir fundinn breytist oft.

Because Icelandic usually adds the definite article to the end of the noun instead of using a separate word.

• dagskrá = agenda / program
• dagskráin = the agenda
• fundur = meeting
• fundinn = the meeting in the accusative singular

So both dagskráin and fundinn already include the meaning of the.

Dagskráin is nominative singular definite.

It is in the nominative because it is the subject of the sentence — the thing that changes. The verb breytist is agreeing with that singular subject.

Base form:

• dagskrá = nominative singular indefinite

Here:

• dagskráin = nominative singular definite

Because the preposition fyrir requires a particular case here, and in this sentence that case is the accusative.

The noun fundur changes form by case:

• fundur = nominative
• fund = accusative indefinite
• fundinn = accusative definite
• fundinum = dative definite

So fyrir fundinn uses the accusative form that fits this preposition in this meaning.

No. Icelandic prepositions often take different cases depending on meaning, and fyrir is one of them.

That means you cannot learn fyrir by itself; it is better to learn it together with its case patterns and common meanings. In this sentence, the correct pattern is fyrir + accusative, which is why you get fundinn.

Breytist is the 3rd person singular present form of breytast.

So grammatically it means:

• present tense
• singular
• he/she/it changes or is changing, depending on context

Here the subject is dagskráin, so breytist means changes.

The -st ending is very common in Icelandic and is often called the middle voice ending.

It can give a verb a meaning that feels:

• reflexive,
• passive-like,
• or intransitive.

With this verb pair:

• breyta = to change something
• breytast = to change, to undergo change

So dagskráin breytist means the agenda changes, not someone changes the agenda.

Because breytir comes from breyta, which is usually transitive — it normally needs an object.

For example:

• Hann breytir dagskránni. = He changes the agenda.

But in your sentence, the agenda itself is the thing undergoing the change, so Icelandic uses breytast:

• Dagskráin breytist. = The agenda changes.

That is why breytist is the natural form here.

Because that is a very normal position for an adverb like oft in Icelandic.

The sentence follows a common main-clause pattern:

• first constituent: Dagskráin fyrir fundinn
• finite verb: breytist
• adverb: oft

So the structure is very natural and neutral.

Icelandic word order is somewhat flexible, but the finite verb in a main clause usually stays in second position.

This sentence is neutral and standard:

• Dagskráin fyrir fundinn breytist oft.

You can also move oft to the front for emphasis:

• Oft breytist dagskráin fyrir fundinn.

That still sounds natural, but it gives a slightly different emphasis. So the word order is flexible, but not random.

In the intended meaning, fyrir fundinn is most naturally understood as describing dagskráin.

So the structure is basically:

• [Dagskráin fyrir fundinn] = the agenda for the meeting
• breytist oft = changes often

In other words, fyrir fundinn belongs with the noun phrase, not mainly with the verb.

The accents in Icelandic are part of the spelling and usually mark a different vowel sound, not just stress.

Two useful ones here are:

• á in dagskráin: roughly like ow in now
• ey in breytist: roughly like ay in day

So even if you do not pronounce them perfectly yet, it helps to remember that accented vowels in Icelandic are usually different vowels, not just emphasized versions of the plain ones.
