Vinkonan mín kemur með okkur í bíó á morgun.

Vinkonan mín means my female friend with the definite article built into the noun.

In Icelandic, the definite article is usually attached to the end of the noun instead of being a separate word like the in English.

• vinkona = a female friend
• vinkonan = the female friend
• vinkonan mín = my female friend

In sentences like this, Icelandic often prefers the definite form with a possessive:

• vinkonan mín = my friend
• literally, something like the friend of mine

You may also see vinkona mín in some contexts, but vinkonan mín is very natural here.

Vinkona means female friend.

It is specifically feminine and refers to a woman or girl who is your friend. Compare:

• vinur = male friend / friend
• vinkona = female friend

So the sentence tells us that the friend is female.

Mín agrees with vinkonan, which is:

• feminine
• singular
• nominative

Icelandic possessives change form depending on gender, number, and case.

Here are a few common forms of my:

• minn = masculine singular
• mín = feminine singular
• mitt = neuter singular

Because vinkonan is feminine singular, the correct form is mín.

Kemur is the 3rd person singular present tense of koma (to come).

The subject is vinkonan mín = my friend, which is singular, so the verb must also be singular:

• ég kem = I come
• þú kemur = you come
• hann / hún / það kemur = he / she / it comes

So:

• Vinkonan mín kemur = My friend comes / is coming

Með okkur means with us.

The preposition með usually takes the dative when it means with in the sense of accompaniment.

The pronoun við (we) changes form after the preposition:

• við = we
• okkur = us

So:

• með okkur = with us

This is a very common pattern in Icelandic: prepositions often require a specific case, and pronouns change form accordingly.

Í bíó is a fixed, very common expression meaning to the cinema / to the movies.

The word bíó often behaves a bit like an idiomatic destination word in this expression, so Icelandic usually says:

• fara í bíó = go to the cinema / go to the movies
• koma í bíó = come to the cinema

You do not normally add the definite article here.

So even though English may say to the cinema or to the movies, Icelandic naturally uses í bíó.

Í usually means in or into, but with certain places and expressions it corresponds to English to.

In í bíó, it expresses going or coming to that activity/location:

• fara í skóla = go to school
• fara í bæinn = go to town
• fara í bíó = go to the cinema

So here í is just the normal Icelandic way to express this idea.

Á morgun is the standard Icelandic expression for tomorrow.

Literally, it looks like:

• á = on
• morgun = morning

But as a whole, á morgun simply means tomorrow.

This is an idiomatic time expression, so it is best learned as a set phrase.

It is at the end because Icelandic often places time expressions later in the sentence, especially after the main action and other complements.

So this order is very natural:

• Vinkonan mín kemur með okkur í bíó á morgun.

A more literal breakdown is:

• My friend comes with us to the cinema tomorrow.

Icelandic word order is somewhat flexible, so á morgun could be moved for emphasis, but the version given is neutral and natural.

Yes. The present tense in Icelandic often covers both:

• simple present: comes
• present progressive: is coming

So Vinkonan mín kemur með okkur í bíó á morgun can naturally be understood as:

• My friend comes with us to the cinema tomorrow or more idiomatically in English:
• My friend is coming with us to the movies tomorrow

English usually prefers is coming here, but Icelandic simply uses the present tense kemur.

Yes: the sentence follows a very common Icelandic pattern:

• Vinkonan mín = subject
• kemur = verb
• með okkur = prepositional phrase
• í bíó = destination/activity
• á morgun = time expression

So the structure is basically:

Subject + Verb + with whom + where/to what + when

This makes it a very useful model sentence for building your own:

• Bróðir minn kemur með mér í bæinn á morgun.
• Kennarinn kemur með okkur í skólann á mánudag.

It is a good example of everyday Icelandic sentence order.
