Matchen är fortfarande oavgjord.

Because -en is the Swedish definite article attached to the noun.

• match = a match
• matchen = the match

Swedish usually puts the at the end of the noun instead of using a separate word like English does.

Swedish normally follows the V2 rule in main clauses: the finite verb usually comes in the second position.

In Matchen är fortfarande oavgjord:

1. Matchen
2. är

So the sentence is perfectly normal Swedish word order.

If you move another element to the front, the verb still stays second:

• Fortfarande är matchen oavgjord.
  This is grammatical, but less neutral and less common in everyday speech.

The most natural version here is Matchen är fortfarande oavgjord.

Fortfarande means still in the sense of continuing to be the case.

It usually comes after the verb är in a simple sentence like this:

• Matchen är fortfarande oavgjord.

That placement is very common with adverbs in Swedish.
Compare:

• Han är fortfarande här.
• Det är fortfarande kallt.

So if you are translating English is still ..., Swedish will often use är fortfarande ....

Because oavgjord is agreeing with matchen, and match is a common gender noun (en word).

Swedish adjectives often change form depending on the noun:

• common gender singular: oavgjord
• neuter singular: oavgjort
• plural / definite contexts: oavgjorda

Examples:

• en match är oavgjord
• ett resultat är oavgjort
• matcherna är oavgjorda

So here matchen is singular and common gender, which is why oavgjord is correct.

It is an adjective.

It comes from the idea of something being undecided / unresolved / drawn depending on context. In sports, it often corresponds to English drawn or tied.

In this sentence it works as a predicative adjective, meaning it comes after the verb är rather than directly before the noun.

Compare:

• en oavgjord match = an undecided/drawn match
• matchen är oavgjord = the match is undecided/drawn

Not exactly, though they can overlap.

In a sentence like this, fortfarande is the most natural choice for still meaning it continues to be so.

• Matchen är fortfarande oavgjord.

Ännu can sometimes mean still, but it often sounds more like yet / as of now, and in many cases it is less natural here than fortfarande.

As a learner, a good rule is:

• use fortfarande for still = continuing state
• use ännu often for yet / still not / up to now, depending on context

Yes, it is possible, and people would understand it. But it is usually a bit less neutral or less common than fortfarande in this kind of everyday statement.

So:

• Matchen är fortfarande oavgjord = very natural
• Matchen är ännu oavgjord = possible, but often feels a bit more formal, literary, or context-dependent

If you are unsure, fortfarande is the safer choice here.

Yes.

It can describe anything that is not decided / unresolved, depending on context. For example:

• Frågan är fortfarande oavgjord.
• Tvisten är oavgjord.

But in sports, it is especially common for a match, game, or result that is still level or has ended in a draw.

So the word is not limited to sports, but sports is one of its most common uses.

A rough guide is:

oh-ahv-yoord

A few useful points:

• o- is a separate prefix meaning un- / not
• avgjord has the main stress
• the j sounds like English y
• the final rd is pronounced with a Swedish retroflex sound in many accents, which may be tricky for English speakers

You do not need perfect pronunciation at first. If you clearly say the parts o + avgjord, people will usually understand you.

Yes. In sports contexts, Swedish also often uses expressions like:

• Det står fortfarande lika.
• Det är fortfarande lika.

These are especially common when talking about the score being level.

But Matchen är fortfarande oavgjord is absolutely correct and natural, especially if you want a slightly more formal or descriptive phrasing.
