Je vais m’asseoir plus loin, car il y a trop de bruit ici.

Yes—vais is literally go (from aller).

But in French, aller + infinitive is a very common way to talk about the near future, just like to be going to + verb in English.

So:

• je vais m’asseoir = I’m going to sit down
• literally: I go myself to-seat

It can sometimes also suggest actual movement depending on context, but here it mainly means the speaker is about to do it.

Because the usual verb for to sit down in French is s’asseoir, which is a reflexive verb.

That means the action is done to oneself:

• je m’assois = I sit down
• tu t’assois = you sit down
• il s’assoit = he sits down

So in je vais m’asseoir, the m’ means myself.

French often uses reflexive verbs where English does not.
In English, we just say sit down. In French, it is normally s’asseoir.

This is because of elision.

When me comes before a word starting with a vowel sound, the e drops:

• me asseoir → m’asseoir

This happens very often in French:

• je aime → j’aime
• me appeler → m’appeler
• te écouter → t’écouter

So m’asseoir is simply the shortened form of me asseoir, which French pronunciation requires.

Plus loin means farther away, further away, or more at a distance.

In this sentence, it means the speaker wants to sit somewhere farther from here.

Examples:

• Je vais m’asseoir plus loin. = I’m going to sit farther away.
• Le village est plus loin. = The village is farther away.

It does not mean later here. It is about distance, not time.

Both car and parce que can mean because.

In this sentence:

• car il y a trop de bruit ici = because there is too much noise here

The difference is mainly style and usage:

car

• often feels a bit more formal or written
• often introduces an explanation

parce que

• more common in everyday spoken French
• the most basic word for because

So you could also say:

• Je vais m’asseoir plus loin, parce qu’il y a trop de bruit ici.

That would sound very natural too.

Il y a is a fixed expression meaning there is or there are.

So:

• il y a trop de bruit = there is too much noise

Although it literally looks like it there has, you should learn il y a as one complete chunk.

Examples:

• Il y a un problème. = There is a problem.
• Il y a deux chaises. = There are two chairs.

French uses this expression where English uses there is / there are.

After expressions of quantity, French normally uses de, not du / de la / des.

So:

• trop de bruit = too much noise
• beaucoup de bruit = a lot of noise
• un peu de bruit = a little noise

This is because trop is a quantity word.

Also, bruit is usually treated as an uncountable noun here, like noise in English.

So trop de bruit is the natural form.

Because after trop de, the article is normally replaced by de.

Compare:

• Il y a du bruit. = There is noise.
• Il y a trop de bruit. = There is too much noise.

So when no quantity word is present, du bruit is possible.
But once you use trop, you switch to de.

French often places words like ici (here) after the main information they relate to.

So:

• il y a trop de bruit ici = there is too much noise here

This word order is very natural in French.

You could sometimes move ici for emphasis, but the version in the sentence is the most normal one.

The end position helps make it clear that the problem is the noise in this place.

In this context, plus loin already implies farther away than the current place.

So Je vais m’asseoir plus loin naturally means:

• I’m going to sit farther away
• in other words, farther from here / farther from this spot

French often leaves that reference implied when it is obvious from context.

If you wanted to be more explicit, you could say:

• Je vais m’asseoir plus loin d’ici

But in many situations, that would sound unnecessary.

Yes, this verb is a little tricky because s’asseoir has some irregular forms and spelling variations.

In m’asseoir, you usually pronounce it roughly like:

• mah-swar or mah-swah-r

The exact pronunciation depends on accent, but the important part is that the oi in modern French usually sounds like wah.

Also, s’asseoir is one of those verbs that learners often need time to get used to, because its conjugation is not as simple as regular -er verbs.

The good news: in this sentence, you only need the infinitive form m’asseoir, which is very common.

Yes, depending on context, that can be a very natural English translation.

Because aller + infinitive can sometimes keep a slight sense of movement, je vais m’asseoir may suggest:

• I’m going to sit down
• I’ll go sit down

In this sentence, the speaker is changing places, so I’ll go sit farther away is actually a very reasonable translation.

So the exact English wording can vary, even though the French stays the same.

The comma separates the main statement from the explanation:

• Je vais m’asseoir plus loin = the action
• car il y a trop de bruit ici = the reason

With car, a comma is very common because car often introduces an added explanation in a fairly clear, separate way.

In informal writing, punctuation may vary, but the comma here is standard and natural.
