Við erum komin á stöðina, en strætóinn er farinn, svo við komumst ekki nógu snemma á fundinn.

Við erum komin is a very common Icelandic way to show a completed movement with a present result.

• við komum = we came / we arrived
• við erum komin = we have arrived / we are here now

So the sentence is not only telling you that the arrival happened. It is also emphasizing the current situation: we are now at the station.

The same pattern appears later in strætóinn er farinn.

Komin is the participle/adjectival form used in this construction with vera (to be).

With við (we) and þið (you plural), Icelandic normally uses komin in this pattern:

• við erum komin
• þið eruð komin

In the 3rd person plural, gender is shown more clearly:

• þeir eru komnir
• þær eru komnar
• þau eru komin

So here komin is the expected form with við.

Because á changes case depending on whether you mean motion toward something or location at something.

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

Here the idea is arriving at the station, so Icelandic uses á stöðina.

Compare:

• Við erum komin á stöðina. = We have arrived at/to the station.
• Við erum á stöðinni. = We are at the station.

So the first one focuses on the arrival endpoint; the second just describes where you are.

Strætóinn means the bus.

The noun is strætó = bus, and Icelandic usually adds the definite article onto the end of the noun instead of using a separate word like English the.

So:

• strætó = bus
• strætóinn = the bus

The same thing happens elsewhere in the sentence:

• stöðina = the station (accusative form)
• fundinn = the meeting (accusative form)

So those endings are not random; they include both definiteness and case.

For the same reason as við erum komin.

• strætóinn fór = the bus left
• strætóinn er farinn = the bus has left / the bus is gone

The form with er farinn emphasizes the result now: the bus is no longer there.

That matters for the next clause, because since the bus is gone, we cannot get to the meeting early enough.

Komumst is from the verb komast, not from koma.

This is an important difference:

• koma = come, arrive
• komast = get somewhere, manage to reach, be able to make it

So:

• við komum = we come / we arrive
• við komumst á fundinn = we get to the meeting / we manage to reach the meeting

In this sentence, komast is the natural choice because the idea is not just coming, but successfully getting there in time.

Because Icelandic very often uses the present tense for future meaning when the context makes the time clear.

So:

• við komumst ekki nógu snemma á fundinn

can mean:

• we won’t get to the meeting early enough
• we can’t get to the meeting early enough

English sometimes does something similar:

• We leave tomorrow.
• I arrive at six.

So this is normal Icelandic usage, not a mistake.

Because Icelandic uses nógu before adjectives and adverbs.

• nógu snemma = early enough
• nógu stór = big enough
• nógu vel = well enough

This is different from English, where enough usually comes after:

• early enough
• big enough
• well enough

Also, ekki normally comes after the finite verb in a main clause:

• við komumst ekki

So the order komumst ekki nógu snemma is exactly what you would expect in Icelandic.

Icelandic often uses á with events, gatherings, and activities, not just physical surfaces.

So you say things like:

• á fund = to a meeting
• á tónleika = to a concert
• á námskeið = to a course

Here á fundinn means to the meeting.

It is accusative because it expresses movement toward the event. If you were already there, you would say:

• á fundinum = at the meeting

Here svo means so / therefore.

It connects the previous idea to the consequence:

• We have arrived at the station,
• but the bus has already left,
• so we cannot get to the meeting early enough.

So svo is showing the result of the situation, not just adding another detail.

Because they do different jobs:

• en = but → contrast
• svo = so / therefore → result

So the sentence is built like this:

1. Við erum komin á stöðina
2. en strætóinn er farinn
   → contrast: we got there, but the bus is gone
3. svo við komumst ekki nógu snemma á fundinn
   → result: so we cannot get to the meeting early enough

This is a very natural way to chain ideas together in Icelandic.
