Við hittumst á eftir vinnu.

The verb here is hittast, not plain hitta.

• hitta = to meet someone / find someone
• hittast = to meet each other, meet up, get together

The ending -st is a very common Icelandic marker often called the middle voice ending. In a sentence like this, it gives the verb a reciprocal sense: we meet each other / we meet up.

So:

• Við hittum Jón. = We meet/met Jón.
• Við hittumst. = We meet/met each other.

That is why hittumst is the natural form here.

In this form, it can actually be understood from context.

In this sentence, the natural reading is present used for the future:

• Við hittumst á eftir vinnu. = We’ll meet after work / We’re meeting after work.

But the same form can also appear in past-time contexts:

• Við hittumst í gær. = We met yesterday.

So the time is often decided by the rest of the sentence, not by the verb form alone.

Because Icelandic very often uses the present tense to talk about the future, especially when there is a time expression that makes the meaning clear.

That is exactly what happens here. The phrase á eftir vinnu makes it clear that the meeting is later, so Icelandic does not need a special future form.

This is similar to English sentences like:

• We’re meeting after work.
• I leave tomorrow.

So this sentence is perfectly normal Icelandic.

Here á eftir means something like later, afterward, or after in context.

You should not translate it too literally word for word. As a phrase, it works idiomatically.

In this sentence:

• á eftir vinnu = after work / once work is over

So the important thing is to learn á eftir as a common time expression, not as separate words that must be translated one by one.

Because Icelandic nouns change form depending on their grammatical role and after certain prepositions or expressions.

The dictionary form is:

• vinna = work

But in many contexts Icelandic uses an oblique case instead of the nominative, and then the form becomes:

• vinnu

For this noun, the singular forms are:

• nominative: vinna
• oblique singular forms: vinnu

So after a phrase like this, vinnu is the expected form.

Because Icelandic normally still uses the subject pronoun.

It is true that -um tells you the verb is 1st person plural (we), but Icelandic is not a language where subject pronouns are usually dropped all the time. So við hittumst is the normal full form.

In other words:

• við = the explicit subject
• -um = extra grammatical information agreeing with that subject

For learners, it is best to include við unless you have a specific reason not to.

Yes, that is also possible.

Both eftir vinnu and á eftir vinnu can point to the idea of after work, though á eftir often has a slightly more conversational later/afterward feel.

So:

• Við hittumst eftir vinnu.
• Við hittumst á eftir vinnu.

Both are understandable and natural, though they are not always felt as perfectly identical in nuance by every speaker. In this sentence, á eftir vinnu sounds idiomatic and everyday.

Yes. Icelandic word order is flexible, but it follows important rules, especially the verb-second pattern in many main clauses.

You can say:

• Við hittumst á eftir vinnu.

But you can also move the time phrase to the front:

• Á eftir vinnu hittumst við.

That still means the same basic thing, but it puts more focus on after work.

Notice what happens when the time phrase comes first:

• first: Á eftir vinnu
• second: hittumst
• then: við

That is a very typical Icelandic pattern.

In natural English, the best translation will usually be either:

• We’re meeting after work
• We’ll meet after work

The Icelandic present tense is broader than a simple literal English present. In context like this, it often covers a planned future event.

So even though the Icelandic verb looks like a present form, the real meaning is often future-oriented.
