Välkommen till mötet.

In this sentence, välkommen is not a finite verb. It is an adjective-like form meaning welcome.

Swedish often uses this kind of short formula without an explicit verb:

• Välkommen till mötet. = Welcome to the meeting.
• literally, it is closer to [You are] welcome to the meeting

So the full idea is understood, even though Swedish leaves out är and du.

That ending is part of the word form used when speaking to one person.

Compare:

• Välkommen = to one person
• Välkomna = to more than one person
• Välkommet = used with a neuter singular word in other contexts

So in Välkommen till mötet, the speaker is welcoming one person.

You would normally say:

• Välkomna till mötet. = Welcome to the meeting. (to several people)

This is a very common difference in Swedish:

• singular person: välkommen
• plural people: välkomna

Till usually means to.

In Välkommen till mötet, it shows the destination or event someone is being welcomed to:

• till mötet = to the meeting

This is the normal preposition in this phrase.

Möte means meeting in the indefinite form:

• ett möte = a meeting

Mötet is the definite form:

• mötet = the meeting

So:

• Välkommen till mötet. = Welcome to the meeting.

Swedish usually puts definiteness at the end of the noun, instead of using a separate word like the.

Because Swedish often adds definiteness as a suffix to the noun.

With möte:

• ett möte = a meeting
• mötet = the meeting

So the -t ending is doing the job that the does in English.

Because möte is an ett-word in Swedish:

• ett möte

For many ett-words, the definite singular ending is -t:

• ett möte → mötet

By contrast, many en-words take -en in the definite singular:

• en bil → bilen

Yes. It is completely natural as a short fixed expression.

Swedish often allows short expressions like this where some words are understood:

• Välkommen!
• Välkommen till Sverige.
• Välkommen till mötet.

You do not need to say Du är välkommen till mötet unless you specifically want the fuller form.

Yes, you could, but it sounds fuller and more explicit.

• Välkommen till mötet. = the normal, natural greeting
• Du är välkommen till mötet. = You are welcome to the meeting, more explicitly stated

The short version is much more common as a greeting.

Roughly, möte sounds something like MUR-teh or MER-teh, but there is no perfect English equivalent.

A few pronunciation notes:

• ö is a rounded vowel that English does not really have
• the final e is pronounced, not silent
• mötet adds a final t sound: MUR-teht / MER-teht

The exact sound depends on accent, but the key point is that ö is not like English o.

Very roughly: VEL-kom-men, but again, not exactly like English.

Important points:

• ä is somewhat like the vowel in English bed, but not identical
• Swedish kom has a short, clear vowel
• the final -en is pronounced

So try something like VEL-kom-men with Swedish-style vowels.

Yes. Swedish does not change this word for male vs female.

So you say:

• Välkommen to one man
• Välkommen to one woman

The important distinction here is singular vs plural, not gender in the English sense.

It is neutral and works in many situations.

You can use it:

• at work
• in an email
• at the start of an event
• when greeting a guest who has arrived for a meeting

It is polite without sounding overly formal.

Yes, absolutely. It is a very natural phrase.

For example, a host, organizer, receptionist, or meeting leader might say:

• Välkommen till mötet.

If several people are arriving, they would more likely say:

• Välkomna till mötet.

Not only. Möte can refer to different kinds of meetings, depending on context:

• a work meeting
• an organized gathering
• a formal meeting
• sometimes other kinds of arranged meetings

So in this sentence, it most likely means the meeting in the ordinary sense of an event or gathering.

Because it is the first word of the sentence.

In Swedish, ordinary nouns are not capitalized the way they are in German. So the capitalization here is just normal sentence capitalization, not anything special about the word Välkommen.
