Hún kemur síðast á fundinn.

Because kemur is the 3rd person singular form of the verb að koma (to come).

• ég kem = I come
• þú kemur = you come
• hún kemur = she comes

So the verb has to match hún (she), which is third person singular.

Hún means she.

It is the nominative singular feminine pronoun, so it is used when she is the subject of the sentence:

• Hún kemur = She comes

Compare:

• hann = he
• það = it

Here síðast means last in the sense of last to arrive or latest.

So in this sentence it tells us the order in which she arrives:

• Hún kemur síðast = She comes last

Be careful: síðast can also mean last time in other contexts, so the exact meaning depends on the sentence.

Because síðast is being used adverbially here, modifying the verb kemur.

It describes how / in what order she comes, not a noun. Adverbs in Icelandic often do not change for gender, number, or case.

So:

• Hún kemur síðast = She comes last

But if you were using a related word as an adjective before a noun, the form could change.

Á fundinn means to the meeting.

It is made up of:

• á = on / onto / to
• fundinn = the meeting in the accusative singular

With motion toward a place, Icelandic often uses:

• á + accusative = movement onto / to
• á + dative = location on / at

So:

• Hún kemur á fundinn = She comes to the meeting
• Hún er á fundinum = She is at the meeting

Because the preposition á here expresses motion toward the meeting, so it takes the accusative case.

The noun is fundur (meeting), and its accusative singular definite form is fundinn (the meeting).

Very roughly:

• fundur = a meeting / meeting (nominative)
• fundinn = the meeting (accusative definite)

So after á with movement, you get:

• á fundinn = to the meeting

The -inn is the suffixed definite article, which is how Icelandic usually says the.

Unlike English, Icelandic often attaches the to the end of the noun.

So:

• fundur = a meeting / meeting
• fundurinn = the meeting (nominative)
• fundinn = the meeting (accusative)

The exact form changes depending on case and grammatical role.

This is a normal Icelandic sentence pattern:

• subject: Hún
• verb: kemur
• adverb: síðast
• prepositional phrase: á fundinn

So literally:

• She comes last to the meeting

That sounds a bit more natural in English as:

• She arrives last at the meeting or
• She comes to the meeting last

Icelandic word order is fairly flexible, but this version is straightforward and natural.

Yes. In many contexts, að koma can be translated as either to come or to arrive, depending on what sounds best in English.

So this sentence could be understood as:

• She comes last to the meeting
• She arrives last at the meeting

English often prefers arrives here, even though Icelandic uses kemur.

Yes, kemur is grammatically present tense.

But like many languages, Icelandic can use the present tense for a future event, especially when the context is clear.

So this sentence could mean either:

• She comes last to the meeting (general or habitual)
• She will come last to the meeting (future, depending on context)

Context tells you which one is meant.

A rough pronunciation guide is:

• Hún ≈ hoon
• kemur ≈ KYEH-mur
• síðast ≈ SEE-thast
• á ≈ ow
• fundinn ≈ FUN-din

A few useful notes:

• ú is a long oo sound
• é is like ye in many words
• ð is like the th in this
• á is like ow in now

The exact pronunciation depends a bit on dialect and speaking speed, but this will get you close.

That would change the meaning from movement toward the meeting to location at the meeting.

Compare:

• á fundinn = to the meeting
• á fundinum = at the meeting

So:

• Hún kemur síðast á fundinn = She arrives last to the meeting
• Hún er síðast á fundinum would mean something different, more like she is last at the meeting, depending on context

This is a very important Icelandic pattern:

• accusative after certain prepositions often shows motion
• dative often shows location
