Annar vafri virkar betur á tölvunni minni.

Here annar means another or a different.

The word annar can also mean second in some contexts, so the exact meaning depends on what is being talked about. In this sentence, with vafri (browser), the natural meaning is:

• another browser
• a different browser

not necessarily the second browser.

Because annar has to agree with vafri in gender, number, and case.

• vafri is masculine
• it is singular
• here it is in the nominative case, because it is the subject of the sentence

So the matching form is annar.

Compare:

• masculine: annar vafri
• feminine: önnur tölva
• neuter: annað forrit

It is nominative singular.

That is because annar vafri is the subject of the verb virkar. In Icelandic, the subject of a normal active sentence is usually in the nominative.

So the structure is:

• Annar vafri = subject
• virkar = verb
• betur = adverb
• á tölvunni minni = prepositional phrase

Because virka means to work, to function, or to operate, and it is very commonly used for things like:

• computers
• software
• apps
• websites
• browsers

So vafri virkar betur means that the browser functions better or works better.

If you said er betri instead, that would mean is better in a more general sense. But virkar betur specifically focuses on how well it performs.

Because betur is an adverb, while betri/betra are adjective forms.

Here, betur modifies the verb virkar:

• virkar betur = works better

It tells us how the browser works.

This is also slightly irregular:

• vel = well
• betur = better
• best = best

Compare:

• betri vafri = a better browser
  Here betri describes the noun.
• vafrinn virkar betur = the browser works better
  Here betur describes the action.

Because á is the preposition used here for being on a computer or device.

In Icelandic, á is very natural with things like computers, screens, websites, and platforms. So á tölvunni minni means on my computer.

Also, á can take different cases depending on meaning:

• dative for location/static position
• accusative for motion/direction onto something

In this sentence, it is about location, not movement, so á takes the dative.

Because tölvunni is the dative singular definite form of tölva (computer).

The noun tölva is feminine. Its forms include:

• nominative: tölva
• accusative: tölvu
• dative: tölvu
• definite dative: tölvunni

So tölvunni means the computer in the dative.

This also shows an important Icelandic feature: the definite article is usually attached to the end of the noun, rather than written as a separate word like English the.

Yes. It is the same possessive word, just in a different grammatical form.

The base forms are:

• masculine: minn
• feminine: mín
• neuter: mitt

But possessives also change for case. Here the noun is tölvunni, which is:

• feminine
• singular
• dative

So the possessive must match that, giving minni.

So:

• mín tölva = my computer
• á tölvunni minni = on my computer

A learner may notice that minni can also look like a form meaning smaller/less in other contexts, but here it is clearly the possessive my.

Because Icelandic very often puts the possessive after the noun in ordinary speech.

So:

• tölvunni minni = my computer

This pattern is extremely common and natural.

When the possessive comes after the noun, the noun is usually definite, which is why you get tölvunni rather than just tölvu.

You can also say:

• á minni tölvu

That is also correct, but it can feel a bit more contrastive or emphatic, like on my computer rather than someone else’s.

So the version in your sentence is a very natural everyday way to say it.

Yes. Icelandic allows different word orders more easily than English, but it follows a strong verb-second pattern in main clauses.

The sentence as written is:

• Annar vafri virkar betur á tölvunni minni.

That starts with the subject, so the verb comes next.

But you could also front another element, for example:

• Á tölvunni minni virkar annar vafri betur.

That still means basically the same thing, but now á tölvunni minni is placed first for emphasis or topic. The verb virkar still stays in the second position, which is a key feature of Icelandic main clauses.
