Anmälningen finns på hemsidan.

Because Swedish usually makes a noun definite by adding an ending, instead of using a separate word like the.

For example:

• hemsida = a homepage / a website
• hemsidan = the homepage / the website

So the ending -n or -en often works like English the.

That is a very common pattern in Swedish:

• bok → boken
• bil → bilen
• hemsida → hemsidan

Finns is used when something exists, is available, or can be found somewhere.

So Anmälningen finns på hemsidan means that the registration/application is there on the website, or available there.

By contrast, är is more for:

• identity: Det är en hemsida
• description: Hemsidan är ny
• location in some cases, especially with people or things simply being somewhere: Jag är hemma

In this sentence, Swedish prefers finns because the idea is you can find it there.

Because finns is the present tense of the verb finnas.

This is just how that verb works:

• infinitive: finnas
• present: finns
• past: fanns

The -s here is not the same as English -s in he runs, and it is not a separate word. It is simply part of the Swedish verb form.

Swedish normally uses på with websites, webpages, and similar digital surfaces.

So:

• på hemsidan = on the website
• på internet
• på Facebook

Using i would usually sound wrong here.

Very roughly:

• på is common for websites/pages/platforms
• i is more common for something being inside a physical space, container, or sometimes inside a text/document

So på hemsidan is the natural choice.

In everyday Swedish, hemsida often means website in general, even though the literal meaning is closer to homepage.

So in real usage:

• hemsida often = website
• webbplats = website, often a bit more precise or formal

That means på hemsidan is a very common everyday way to say on the website.

This is a good question, because many learners will more often see anmälan.

In modern standard Swedish, anmälan is very common for meanings like:

• registration
• application
• report
• notification

So in many contexts, Swedish speakers would more naturally say:

• Anmälan finns på hemsidan.

The form anmälningen is understandable, but it may sound less usual depending on the context. So if you meet anmälan elsewhere, that is not a contradiction — it is often the more common form.

Yes. The sentence given has the neutral order:

• Anmälningen finns på hemsidan.

But you could also move the location to the front:

• På hemsidan finns anmälningen.

That sounds a bit more like On the website, the registration is available.

This shows an important Swedish rule: in a main clause, the finite verb usually stays in second position. So when på hemsidan moves to the front, finns still comes second.

Not in this sentence.

When the noun already has the definite ending, Swedish usually does not add a separate article:

• hemsidan = the website
• anmälningen = the registration

But if there is an adjective, Swedish often uses double definiteness:

• den nya hemsidan = the new website

So:

• no adjective: hemsidan
• with adjective: den nya hemsidan
