Je passerai te voir après le boulot.

It’s a very natural French way to say come by to see you, drop by and see you, or stop in to see you.

So Je passerai te voir suggests:

• the speaker will come to where you are
• probably for a visit that is not very long or very formal
• it sounds more like I’ll stop by than I will go see you for a planned visit

The verb passer often adds this idea of stopping by or passing through.

Passerai is the future simple of passer.

It comes from:

• infinitive: passer
• future stem: passer-
• ending for je: -ai

So:

• je passerai = I will stop by / I will come by

In this sentence, it shows that the action will happen later, after work.

Both are possible.

• Je passerai te voir = I’ll come by to see you
• Je vais passer te voir = I’m going to come by to see you

The difference is mostly one of style and nuance:

• future simple can sound a bit more neutral, definite, or matter-of-fact
• aller + infinitive often sounds a bit more immediate or conversational

In everyday spoken French, both are common.

Because te is the correct object pronoun here.

In French, when you is the direct object of the verb, you usually use:

• me
• te
• le / la
• nous
• vous
• les

So:

• te voir = to see you

Toi is a stressed pronoun, not the normal object pronoun. You use toi in other situations, for example:

• after a preposition: avec toi
• for emphasis: Toi, tu comprends
• in comparisons or contrasts

So te voir is correct, and toi voir is not.

Because te belongs to voir, and French object pronouns usually go right before the verb they belong to.

Here:

• passer = to stop by / come by
• voir = to see
• te = the object of voir

So the structure is:

• passer te voir = come by to see you

A useful comparison:

• Je vais te voir = I’m going to see you
• Je veux te voir = I want to see you
• Je passerai te voir = I’ll stop by to see you

In all of these, te goes before voir, because you is the person being seen.

Usually, yes.

Because of passer, the sentence often suggests:

• a brief visit
• stopping by on the way or during the day
• something casual rather than a big planned event

It does not absolutely have to be short, but that is the usual feeling.

If you said:

• J’irai te voir

that sounds more simply like I’ll go see you, without the same drop by nuance.

Because it isn’t necessary.

Passer voir quelqu’un already means to go and see someone / stop by to see someone, so the place is often understood.

If you want to make the location explicit, you can say:

• Je passerai te voir chez toi après le boulot.

But without chez toi, the sentence is still completely natural.

Boulot means work or job, but it is informal / colloquial.

So:

• après le boulot = after work

A more neutral or formal version would be:

• après le travail

Both are common, but:

• boulot sounds more casual and everyday
• travail is more neutral and works in all situations

Because French normally uses the definite article here.

So French says:

• après le boulot
• après le travail
• après le dîner

Even though English often says just after work, French usually prefers after the work / after the job structurally.

So après boulot would sound incomplete in standard French.

Yes, partly.

The sentence sounds informal for two reasons:

• te is used with someone you address as tu
• boulot is a casual word

So Je passerai te voir après le boulot is natural with:

• a friend
• a partner
• a family member
• someone you know well

A more formal or polite version would be:

• Je passerai vous voir après le travail.

That changes both:

• te → vous
• boulot → travail
