Við tökum illgresið úr garðinum á morgun.

Because Icelandic very often uses the present tense to talk about the future when the time is clear from context.

Here, á morgun means tomorrow, so Við tökum ... á morgun naturally means We’ll take/remove ... tomorrow.

This is very similar to English sentences like:

• We leave tomorrow
• I see her next week

So there is no problem with using the present form here.

The dictionary form is taka, meaning to take.

Tökum is the 1st person plural present indicative form: we take.

A few present-tense forms of taka are:

• ég tek — I take
• þú tekur — you take
• við tökum — we take
• þeir taka — they take

So við tökum = we take / we will take, depending on context.

The ending -ið is the definite article attached to the noun.

The base noun is illgresi, meaning weed or weeds/weedy growth.
With the suffixed article, illgresið means the weed(s).

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

So:

• illgresi — weed / weeds / weed growth
• illgresið — the weed(s)

Grammatically, illgresið is singular neuter. But semantically it often works like a collective noun.

So although the form is singular, English often translates it as weeds, because that sounds more natural in context.

You can think of it as something like:

• the weed growth
• the weeds

Both ideas are close, and English usually prefers weeds here.

It is the direct object of tökum, so it is in the accusative case.

However, with many neuter singular nouns in Icelandic, the nominative and accusative forms look the same. So even though it is accusative here, the form is still illgresið.

Because the preposition úr takes the dative case.

The noun is garður (garden), and after úr it changes to the dative definite form:

• garður — garden
• garðinum — the garden (dative)

So:

• úr garðinum = out of the garden / from the garden

By contrast:

• garðinn is accusative definite
• garðurinn is nominative definite

Those would not be correct after úr.

Úr means out of or from.

In this sentence, úr garðinum means from the garden or more literally out of the garden.

It suggests removal from inside a place or area. That is why it fits well with taking weeds out of a garden.

Both can relate to from, but they are not exactly the same.

• úr often means out of, with a sense of being removed from inside something or from within an area
• frá is more general: from, away from

With weeds being removed from a garden, úr garðinum is very natural because it suggests taking something out of that space.

Yes. Á morgun is the normal expression for tomorrow.

Even though á often means on, you should mostly learn á morgun as a set phrase.

So:

• í dag — today
• á morgun — tomorrow
• í gær — yesterday

Yes. Icelandic word order is fairly flexible, but it follows verb-second rules in main clauses.

The sentence you have is:

• Við tökum illgresið úr garðinum á morgun.

You could also say:

• Á morgun tökum við illgresið úr garðinum.

That version emphasizes tomorrow a bit more. Notice that when Á morgun comes first, the verb tökum still stays in the second position, and við moves after it.

In a normal declarative sentence, við is usually kept.

So the standard form is:

• Við tökum illgresið úr garðinum á morgun.

If you say:

• Tökum illgresið úr garðinum á morgun

that can sound more like a suggestion, roughly Let’s remove the weeds from the garden tomorrow.

So including við makes it clearly a statement: We will remove the weeds tomorrow.

Both endings show the definite article attached to the noun.

• illgresið = the weeds / the weed growth
• garðinum = the garden (in the dative case)

So Icelandic is doing two things at once with these endings:

1. marking the
2. marking the noun’s grammatical case

That is one reason Icelandic noun forms can look more complex than English ones.
