Við skiljum ekki hjólbörurnar eftir á grasflötinni yfir nótt.

A very common learner question. Skilja has more than one meaning in Icelandic.

In this sentence, the verb is not just skilja by itself, but the combination skilja eftir, which means leave behind or simply leave in this context.

So:

• skilja = can mean understand
• skilja eftir = leave behind

That is why you should understand Við skiljum ekki ... eftir as one unit: We do not leave ... behind.

Because skilja eftir is a verb-plus-particle combination, and in Icelandic the object often goes between the verb and the particle.

So the pattern is commonly:

skilja + object + eftir

Here that gives:

Við skiljum ekki hjólbörurnar eftir

This is very normal Icelandic word order. English also does something similar in some expressions, compare:

• pick the book up
• leave the wheelbarrows behind

So eftir belongs with the verb, even though it is not right next to it.

Skiljum is the 1st person plural present tense form of skilja.

That means it corresponds to we leave or sometimes we are leaving, depending on context.

The ending -um is a useful clue: it often marks we forms in the present tense.

So:

• ég skil = I understand / I leave
• við skiljum = we understand / we leave

In this sentence, because of eftir, it means we leave behind.

Because Icelandic main clauses usually follow the verb-second rule. That means the finite verb normally comes early in the sentence, typically in second position.

So in:

Við skiljum ekki hjólbörurnar eftir ...

the order is:

• Við = subject
• skiljum = finite verb
• ekki = not

This is the normal pattern. A native English speaker may expect something like we not leave, but Icelandic does not work that way.

It is the direct object of skiljum eftir, so its role in the sentence is accusative.

In other words, it is the thing being left.

So the logic is:

• Við = the people doing the action
• skiljum eftir = leave behind
• hjólbörurnar = what is being left

For many feminine plural nouns, the nominative and accusative forms look the same, so learners do not always see a visible case change here. But syntactically, this noun is functioning as the accusative object.

Because Icelandic usually adds the definite article to the end of the noun instead of using a separate word like English the.

So:

• hjólbörur → hjólbörurnar
• grasflöt → grasflötinni

That suffix is how Icelandic often expresses the.

This is one of the biggest structural differences from English. Instead of saying the lawn with a separate article, Icelandic often says one combined form: grasflötinni.

Because á can take different cases depending on meaning:

• accusative for movement onto something
• dative for location on something

Here the sentence describes location, not movement. The wheelbarrows are being left on the lawn, so Icelandic uses the dative:

á grasflötinni

Compare the difference:

• á grasflötina = onto the lawn
• á grasflötinni = on the lawn

That is a very important Icelandic pattern with prepositions like á and í.

It is the definite singular dative form of grasflöt, meaning the lawn in this sentence.

You can break it down like this:

• grasflöt = lawn
• -inni = a dative definite ending here

So á grasflötinni means on the lawn.

Even if you do not memorize the full declension immediately, it is useful to notice that the ending changes because the preposition á requires a particular case here.

Yes, yfir often means over, but in time expressions it can mean through or for the duration of.

So yfir nótt means overnight or through the night.

This is a common idiomatic expression, so it is best learned as a chunk:

yfir nótt = overnight

A learner should not translate it too literally word by word.

Because Icelandic often uses a bare noun in fixed time expressions.

So yfir nótt is a standard idiomatic phrase meaning overnight.

This is similar to how languages often keep certain time phrases in a set form rather than using the full definite noun every time. For a learner, the safest approach is simply to remember:

yfir nótt = overnight

Sometimes yes, because the verb form skiljum already shows 1st person plural.

So from grammar alone, Skiljum ekki hjólbörurnar eftir ... could be understood as We do not leave ...

However, Icelandic often keeps subject pronouns in normal speech and writing, especially when there is no strong reason to omit them. So Við skiljum ekki ... sounds completely natural and clear.

Grammatically, it is present tense, but the exact English interpretation depends on context.

It can mean something like:

• a general rule or habit: We don’t leave the wheelbarrows on the lawn overnight
• a present situation: We aren’t leaving the wheelbarrows on the lawn overnight

Icelandic present tense often covers both kinds of meaning, just as English sometimes does.

A useful way to see it is:

• Við = subject
• skiljum = finite verb
• ekki = negation
• hjólbörurnar = object
• eftir = particle belonging to the verb
• á grasflötinni = place
• yfir nótt = time

So the sentence follows a very natural Icelandic pattern:

Subject + verb + not + object + particle + place + time

The exact order of place and time phrases can sometimes vary, but this version is perfectly normal and idiomatic.
