Ég er vanur að taka með mér snarl í vinnuna, svo ég verði ekki of svangur seinnipartinn.

Að vera vanur að + infinitive means to be used to doing something or to be in the habit of doing something.

So:

• Ég er vanur að taka með mér snarl í vinnuna
  = I am used to taking a snack with me to work / I’m in the habit of bringing a snack to work

It describes a usual personal habit, not a one-time action.

Vanur is an adjective, and it has to agree with the person being described.

Here the subject is ég = I, and the speaker is grammatically masculine, so the form is:

• vanur = masculine singular
• vön = feminine singular
• vant = neuter singular

So a female speaker would normally say:

• Ég er vön að taka með mér snarl í vinnuna ...

This is one of the first things learners notice about Icelandic: even in a sentence meaning I am used to..., the adjective changes depending on the speaker.

After vanur, Icelandic normally uses að + infinitive.

So:

• vanur að taka = used to taking
• literally, something like accustomed to take

This is just the regular construction:

• Ég er vanur að vakna snemma. = I’m used to waking up early.
• Hún er vön að lesa á kvöldin. = She’s used to reading in the evenings.

So the að is not optional here.

Að taka með sér means to take/bring with oneself.

In the sentence:

• taka með mér snarl
  = take a snack with me / bring a snack along

The phrase uses með + dative pronoun:

• með mér = with me
• með þér = with you
• með sér = with himself/herself/itself/themselves

So með mér is not just an extra word — it shows that the speaker is bringing the snack along personally.

Because the preposition með normally takes the dative in this meaning.

So the pronoun after it must be dative:

• ég → mér
• þú → þér
• hann → honum
• hún → henni

That is why you get:

• með mér = with me

not með mig.

This is something you just have to learn together with the preposition: með often governs the dative.

This is about the difference between motion toward a place and location in a place.

With í:

• accusative often shows movement into/to
• dative often shows being in

So:

• í vinnuna = to work / into work
• í vinnunni = at work / in the workplace

In this sentence, the snack is being taken to work, so Icelandic uses the motion form:

• í vinnuna

Compare:

• Ég fer í vinnuna. = I go to work.
• Ég er í vinnunni. = I am at work.

Vinnuna is the accusative singular definite form of vinna in this sentence.

Breakdown:

• vinna = work
• vinnuna = the work / to work, in this expression

After í with movement, Icelandic uses the accusative, so:

• í vinnuna

This is a very common pattern:

• í skólann = to school
• í búðina = to the shop
• í bæinn = into town

Even when English just says to work, Icelandic often uses a noun with the article in this kind of phrase.

Because this svo clause expresses purpose/result intended by the speaker, and Icelandic often uses the subjunctive there.

So:

• svo ég verði ekki of svangur
  = so that I don’t get too hungry

The verb verði is the present subjunctive of verða.

This is very common after svo (að) when the meaning is so that, especially in more careful or standard Icelandic.

Compare:

• Ég tek með mér snarl svo ég verði ekki svangur.
  = I bring a snack so that I won’t get hungry.

If you used verð, that would be indicative and would sound different in tone or less standard in this kind of purpose clause.

Verði is from verða, not vera.

That matters because:

• vera = to be
• verða = to become / get

Here the meaning is:

• ég verði ekki of svangur
  = I do not become/get too hungry

So the speaker is not saying so that I am not too hungry, but rather so that I don’t get too hungry later.

A few useful forms of verða:

• ég verð = I become / I get
• ég varð = I became
• ég verði = I become / may become (subjunctive)

Svangur is an adjective and has to agree with the person who is hungry — here, ég.

Since the speaker is grammatically masculine singular, the form is:

• svangur = masculine singular
• svöng = feminine singular
• svangt = neuter singular

So a female speaker would say:

• ... svo ég verði ekki of svöng seinnipartinn.

Again, Icelandic adjectives often reflect the gender and number of the subject.

Here of means too or overly, not the English preposition of.

So:

• of svangur = too hungry

Examples:

• of heitt = too hot
• of dýrt = too expensive
• of seint = too late

So:

• ekki of svangur = not too hungry

This is a very common little word, and English speakers often do a double take because it looks familiar but means something different.

Seinnipartinn means later in the day, often in the afternoon or later on in the afternoon/day, depending on context.

It comes from:

• seinni partur = later part
• seinniparturinn = the later part
• seinnipartinn = accusative form, used adverbially here

In this sentence:

• seinnipartinn
  = later in the day / in the afternoon

So the idea is that the speaker brings a snack to avoid getting too hungry later on.

Because seinnipartinn is a set time expression meaning in the latter part of the day / in the afternoon.

It is more specific than seint, which usually just means late.

Compare:

• seint = late
• seinnipartinn = later in the day / in the afternoon

So:

• Ég verð svangur seinnipartinn.
  = I get hungry later in the day / in the afternoon.

This kind of time expression often appears in a case form that functions adverbially in Icelandic.

Because ekki negates the adjective phrase that follows.

So:

• ég verði ekki of svangur
  = I don’t get too hungry

The structure is:

• verb + ekki
  • adjective phrase

This is normal Icelandic word order in a clause like this.

If you think of it as:

• not too hungry

the placement makes sense.

Yes, snarl is a noun, and here it means a snack or snack food.

It appears without the article because the speaker means a snack in a general, indefinite sense:

• taka með mér snarl = bring a snack / bring some snack food

If the speaker wanted something definite, Icelandic could use a definite form or a different phrasing depending on context. But here the indefinite, general idea is the natural one.

Yes. Even though er vanur að literally means am used to, in natural English this sentence could often be rendered as:

• I usually bring a snack to work so I don’t get too hungry in the afternoon.

That is because vera vanur að often describes a regular habit, not just a state of being accustomed to something.

So both of these capture the idea well:

• I’m used to bringing a snack to work...
• I usually bring a snack to work...

The exact best translation depends on the context.

Yes — at least the adjectives that refer to ég would change.

Masculine speaker:

• Ég er vanur ... svo ég verði ekki of svangur ...

Feminine speaker:

• Ég er vön ... svo ég verði ekki of svöng ...

What changes:

• vanur → vön
• svangur → svöng

The rest of the sentence stays the same.

It breaks down like this:

• Ég er vanur að taka með mér snarl í vinnuna
  = main clause: I am used to bringing a snack to work

• svo ég verði ekki of svangur seinnipartinn
  = purpose clause: so that I don’t get too hungry later in the day

So the full sentence is:

• main habit
  • reason/purpose

A very literal gloss would be:

• I am used to take with me snack to work, so that I become not too hungry later in the day.

But natural English would be:

• I usually bring a snack to work so I don’t get too hungry later in the afternoon.
