Barnet ville åka rutschkana igen, men hon snubblade i sanden först.

Yes. Barn is an ett-word, so barnet means the child and is grammatically neuter.

But Swedish can switch from grammatical gender to natural gender when talking about a person. So once the child is being referred to as an actual girl, hon is perfectly natural.

So these are both possible in different contexts:

• Barnet ... det ... = focusing on the noun grammatically
• Barnet ... hon ... = focusing on the child as a girl

In real Swedish, using hon or han for a child is very common when the child’s sex is known.

Ville is the past tense of vilja, which means to want.

So:

• vill = wants
• ville = wanted

After ville, Swedish uses the infinitive of the next verb:

• ville åka = wanted to go / wanted to ride / wanted to slide

This is similar to English wanted to + verb.

So:

• Barnet ville åka rutschkana = The child wanted to go on the slide / wanted to slide

Because åka rutschkana is an idiomatic Swedish expression.

Here rutschkana works almost like the name of an activity, not just a physical object. Swedish often uses a bare noun like this after certain verbs:

• köra bil = drive a car / drive
• spela piano = play the piano
• åka skidor = ski
• åka rutschkana = go on the slide / slide

If you say åka på rutschkanan, it sounds more literal and specific: ride on the slide or go on that particular slide. The bare form åka rutschkana is the normal way to describe the activity.

Also, rutschkana is a compound noun:

• rutsch = sliding
• kana = track/run/chute

Together: slide

Igen means again.

In this sentence, it comes after the whole activity:

• ville åka rutschkana igen = wanted to go on the slide again

That placement is very natural in Swedish. It usually comes after the verb phrase or after the thing being repeated.

Compare:

• Hon ville prova igen = She wanted to try again
• Han läste boken igen = He read the book again

So here, igen tells us that the child wanted to repeat the activity of sliding.

Sanden means the sand.

Swedish often uses the definite form where English might be less strict about it, especially when the context makes the thing identifiable. In a playground context, i sanden naturally means in the sand there at the place.

So:

• i sanden = in the sand
• i sand would sound more like in sand as a material, which is less natural here

Since the sentence is about a child at a slide or playground, sanden refers to the specific sand on the ground in that setting.

Here först means something like:

• first
• before that
• before she could do that

So the sense of the sentence is:

• The child wanted to go on the slide again, but first she tripped in the sand.

It does not mean that tripping was part of some ordered list. It marks that the tripping happened before the intended action of sliding again.

In English, a very natural translation would be:

• The child wanted to go on the slide again, but first she tripped in the sand.

or

• The child wanted to go on the slide again, but she tripped in the sand first.

Because men is a coordinating conjunction, like but in English.

It joins two main clauses:

1. Barnet ville åka rutschkana igen
2. hon snubblade i sanden först

After men, Swedish usually keeps normal main-clause word order:

• subject + verb
• hon snubblade

There is no inversion just because of men.

You get inversion after something placed first in the clause, like:

• Sedan snubblade hon = Then she tripped
• I sanden snubblade hon = In the sand she tripped

But after men, normal order is used:

• men hon snubblade

Snubblade is the past tense of snubbla, which means to trip or to stumble.

So:

• snubbla = to trip
• snubblar = trips / is tripping
• snubblade = tripped

This is a very common Swedish weak-verb pattern where the past tense ends in -de or -te.

So the sentence is narrating two past events:

• ville = wanted
• snubblade = tripped

Yes, absolutely.

You could say:

• Barnet ville åka rutschkana igen, men barnet snubblade i sanden först.

That is grammatical, but it sounds a bit more repetitive.

Using hon is more natural once the child has already been introduced. Swedish, like English, usually prefers a pronoun instead of repeating the noun right away.

So:

• barnet ... hon ... = natural
• barnet ... barnet ... = grammatical but repetitive

Yes. It is a very typical Swedish compound noun.

• rutsch = slide/sliding
• kana = chute, track, run

Together, they make rutschkana, meaning slide.

Swedish forms compounds very freely, and learners often need to get used to reading long words as smaller parts. So rutschkana is one word, not two.

This is extremely common in Swedish:

• lekplats = playground
• glasspinne = popsicle / ice-cream stick
• fotbollsmål = football goal / soccer goal

So rutschkana is a good example of how Swedish packs meaning into one compound word.
