Vi vet inte den exakta tiden för mötet ännu.

Because in a normal Swedish main clause, the finite verb usually comes before sentence adverbs like inte.

So:

• Vi vet inte ... = correct
• Vi inte vet ... = not normal in a main clause

This is a very common Swedish word-order pattern. English says do not know, but Swedish puts inte after the verb:

• Jag kommer inte. = I am not coming.
• Hon bor inte här. = She does not live here.

Because the sentence refers to a specific time: the exact time, not just exact time in a general sense.

Swedish often uses a definite structure when English uses the:

• den exakta tiden = the exact time

If you said exakt tid, that would sound more like exact time as a general concept, not a specific known item.

Yes, in a way it is — and that is normal in Swedish. This is called double definiteness.

When a noun is definite and has an adjective before it, Swedish usually marks definiteness twice:

• with a separate word: den
• and with the definite ending on the noun: -en

So:

• tiden = the time
• den exakta tiden = the exact time

You cannot normally say exakta tiden by itself here, and den exakta tid is also wrong.

Because the adjective is modifying a definite noun phrase: den ... tiden.

Compare:

• en exakt tid = an exact time
• den exakta tiden = the exact time

In Swedish, adjectives change form depending on whether the noun is indefinite, definite, singular, plural, and sometimes gender. In a definite phrase like this one, the adjective usually takes -a:

• den stora bilen = the big car
• det stora huset = the big house
• de stora bilarna = the big cars

So exakta is the correct definite form.

Because tid is a common-gender noun and here it is definite.

• tid = time
• tiden = the time

For many common-gender nouns, the definite singular ending is -en.

Examples:

• bok → boken
• bil → bilen
• tid → tiden

So tiden simply means the time.

Here för means for in the sense of for the meeting or connected with the meeting.

So:

• tiden för mötet = the time for the meeting

This is a natural Swedish way to express it. In English, you might also say the time of the meeting, but Swedish commonly uses för in this kind of phrase.

Because it refers to a specific meeting, not just any meeting.

• möte = meeting
• mötet = the meeting

So:

• för mötet = for the meeting

If you said för ett möte, that would mean for a meeting, which is less specific.

Here ännu means yet.

So:

• Vi vet inte ... ännu. = We don’t know ... yet.

It shows that the situation may change later. Right now the exact time is unknown, but maybe it will be known later.

A few related words:

• ännu = yet / still, depending on context
• redan = already

Examples:

• Jag har inte ätit ännu. = I haven’t eaten yet.
• Hon är ännu hemma. = She is still at home.

Because that is a very natural position for yet in Swedish.

• Vi vet inte den exakta tiden för mötet ännu.

This sounds completely normal. You may also see ännu in other positions, but the final position is especially common when it means yet.

For example:

• Vi vet ännu inte den exakta tiden för mötet.

This is also possible, but the version with ännu at the end is often simpler and more natural for learners to recognize.

Yes, you could, but it is slightly different in tone.

• vi vet inte = we do not know
• vi känner inte till = we are not familiar with / we do not know about

In this sentence, vi vet inte is the most straightforward and natural choice. Känner till is often used more for being aware of information or knowing about something.

So vi vet inte den exakta tiden is the best basic version here.

The sentence breaks down like this:

• Vi = we
• vet = know
• inte = not
• den exakta tiden = the exact time
• för mötet = for the meeting
• ännu = yet

So the structure is:

• subject: Vi
• verb: vet
• negation: inte
• object: den exakta tiden
• prepositional phrase: för mötet
• time-related adverb: ännu

This is a very typical Swedish sentence pattern.
