Mötet pågår.

Because mötet is the definite singular form of the noun möte, which means meeting.

• ett möte = a meeting
• mötet = the meeting

So the ending -et corresponds to English the for this neuter noun.

The base form is pågå, which means to be in progress, to go on, or to continue.

In this sentence:

• pågå = infinitive
• pågår = present tense

So Mötet pågår literally means something like The meeting is ongoing or The meeting is in progress.

It is present tense.

In Swedish, present tense verbs usually end in -r:

• att pågå = to be in progress
• pågår = is in progress / goes on

Swedish uses the present tense here where English often uses a progressive form such as is going on or is taking place.

Because pågår already contains the full verbal idea.

English often uses:

• is in progress
• is going on

But Swedish can express that with just one verb:

• pågår

So Mötet pågår is a complete sentence with:

• Mötet = subject
• pågår = verb

No extra is is needed.

Yes, in meaning it often corresponds to the English present continuous.

Swedish does not usually have a special verb form like is happening or is running in the same way English does. The normal present tense often covers both:

• Mötet pågår = The meeting is in progress
• Lektionen börjar = The lesson is starting / starts
• Han jobbar = He works / He is working

So here the Swedish present tense can sound more like an ongoing action in English.

Mötet is pronounced approximately MUR-tet or MÖH-tet, depending on how closely you want to imitate Swedish sounds.

A few pronunciation points:

• ö is a vowel that does not exist exactly in English
• it is somewhat similar to the vowel in French peu or German schön
• the stress is on the first syllable: MÖ-tet

The final -et is pronounced clearly, not like English silent letters.

Approximately POH-gor with the stress on the second part: på-GÅR.

A few details:

• på has a long å sound, roughly like aw in some pronunciations of law
• går also has å
• the g is a hard g

So the rhythm is roughly:

• MÖ-tet på-GÅR

Möte is a neuter noun in Swedish, so it takes ett in the indefinite form:

• ett möte = a meeting
• mötet = the meeting

This is why the definite ending is -et.

A common pattern is:

• ett + noun
• definite singular often -et

Yes, but the verb still follows normal Swedish sentence rules.

Basic statement:

• Mötet pågår.

If you add another element at the beginning, the verb usually comes second:

• Nu pågår mötet. = Now the meeting is in progress.
• Just nu pågår mötet. = The meeting is going on right now.

To make a yes/no question, Swedish often puts the verb first:

• Pågår mötet? = Is the meeting in progress?

So word order matters a lot in Swedish.

Usually, Mötet pågår is the more natural and precise expression for The meeting is in progress.

Hålla på often means to be busy doing something or to be in the middle of something, but it is used differently and often with another verb:

• Jag håller på att laga mat. = I am cooking / I am in the middle of cooking.

For an event such as a meeting, match, discussion, festival, or process, pågår is very common:

• Matchen pågår.
• Diskussionen pågår.
• Arbetet pågår.

So for this sentence, Mötet pågår is the best standard choice.

Yes, very often. It is used for events, activities, processes, and situations that are ongoing.

Examples:

• Filmen pågår fortfarande. = The film is still on / still running.
• Arbetet pågår hela veckan. = The work is going on all week.
• En utredning pågår. = An investigation is underway.
• Kriget pågår fortfarande. = The war is still going on.

So pågå is a very useful verb for anything that is currently happening or continuing.
