Hun spiser yoghurt hver morgen, og senere legger hun en banan i vesken.

Because yoghurt is being used as a mass noun here, like water or rice in English. In that use, Norwegian normally does not use en or ei.

So:

• Hun spiser yoghurt = She eats yogurt
• Hun spiser en yoghurt = She eats a yogurt / a cup of yogurt

If you mean one specific container or serving, en yoghurt is possible. But in this sentence, it sounds more general and natural without an article.

Because hver + singular noun is the normal pattern for every/each in Norwegian.

So:

• hver morgen = every morning
• hver dag = every day
• hver uke = every week

After hver, the noun stays in its basic singular form, not the definite form. That is why hver morgenen is incorrect.

Also, hver morgen means repeated habit, while om morgenen usually means in the morning more generally.

They are both in the present tense:

• spiser = eats / is eating
• legger = puts / lays

In this sentence, the present tense is being used for a habitual action, just like in English:

• Hun spiser yoghurt hver morgen = She eats yogurt every morning

So this is not about what she is doing right now only; it describes a routine.

This is because Norwegian follows the V2 rule in main clauses. That means the finite verb usually comes in the second position.

Here, senere is placed first for emphasis, so the verb must come next:

• Senere legger hun en banan i vesken

Structure:

• Senere = first element
• legger = verb in second position
• hun = subject after the verb

This is very common in Norwegian. Compare:

• Hun legger senere en banan i vesken = possible, but less natural here
• Senere legger hun en banan i vesken = more natural if you want to emphasize later

Because the second part is a new main clause, and Norwegian normally needs the subject to be stated again.

So:

• Hun spiser yoghurt hver morgen, og senere legger hun en banan i vesken.

The two clauses are:

1. Hun spiser yoghurt hver morgen
2. senere legger hun en banan i vesken

Even though it is the same person doing both actions, Norwegian still includes hun in the second clause.

Å legge often means to lay or to place something somewhere. It is a very common verb for putting an object into or onto something.

So:

• legger en banan i vesken = puts a banana in the bag

It is a good natural choice here.

Other verbs are possible in some contexts:

• å putte = to put/stick something in, often a bit more casual
• å sette = to set/put upright
• å plassere = to place, more formal

In everyday Norwegian, legge is very common for this kind of action.

Because vesken means the bag, and here it is understood that it is a specific bag, probably her own.

So:

• i vesken = in the bag
• i en veske = in a bag

Norwegian often uses the definite form where English might prefer a possessive, especially when the owner is obvious from context.

So i vesken can sound very natural where English might say in her bag.

Yes. I vesken sin means in her bag more explicitly.

Compare:

• i vesken = in the bag
• i vesken sin = in her bag

Both can be correct. The shorter i vesken is natural when the context already makes it clear whose bag it is.

Both can be correct in Bokmål.

The noun veske can be treated in two common ways:

• en veske – vesken
• ei veske – veska

So:

• i vesken
• i veska

Both mean the same thing. The choice depends on style, dialect, and personal preference. Vesken is often a bit more neutral or common in written Bokmål, while veska may sound more colloquial or reflect dialect use.

Here, senere means later or later on.

It tells you that the second action happens after the first one.

So the timeline is:

1. She eats yogurt every morning.
2. Later, she puts a banana in the bag.

Other similar words you may see are:

• etterpå = afterwards / afterward
• så = then
• senere = later

In this sentence, senere works well because it simply marks a later time.

Because the sentence contains two full main clauses joined by og:

• Hun spiser yoghurt hver morgen
• senere legger hun en banan i vesken

In Norwegian, a comma is normally used between coordinated main clauses like these.

So the comma is correct and expected here, even though English punctuation can sometimes be more flexible with and.
