Ik ga er ook van uit dat jij morgen op tijd bent voor het overleg.

Because uitgaan van is a fixed verb expression, and uitgaan is a separable verb.

In a main clause, the conjugated verb goes near the front, while the separable part usually moves toward the end:

• infinitive: uitgaan van iets
• main clause: Ik ga ... van uit

So:

• Ik ga ervan uit = I assume

The van belongs to the expression, and uit is the separable particle from uitgaan.

Er stands in for iets / dat / this / it after a preposition.

With van uitgaan, you often assume something. Instead of repeating that thing directly, Dutch uses er:

• Ik ga uit van dat plan sounds unnatural here.
• Ik ga ervan uit is the normal way to say I assume that.

You can think of ervan as roughly of it / about that, though idiomatically the whole phrase means to assume.

No, not in standard Dutch.

When van refers forward to a whole clause introduced by dat, Dutch normally uses er:

• Ik ga ervan uit dat jij morgen op tijd bent.

So the pattern is:

• ervan uitgaan dat ... = to assume that ...

That is the standard structure.

It is at the end of the subordinate clause introduced by dat:

• main clause: Ik ga er ook van uit
• subordinate clause: dat jij morgen op tijd bent voor het overleg

In Dutch subordinate clauses, the finite verb usually goes toward the end. That is why you get:

• dat jij ... bent

and not:

• dat jij bent ... in normal word order.

Dutch often uses the present tense for future events when the time is already clear from context.

Here, morgen already shows that the action is in the future:

• dat jij morgen op tijd bent

This is very normal Dutch, just like English can say:

• You are on time tomorrow in some contexts,

though English usually prefers will be. Dutch uses the present more freely here.

You could also say:

• dat jij morgen op tijd zult zijn

but that is often less natural in everyday speech.

Both are possible, but jij is the stressed/emphatic form.

• dat je morgen op tijd bent = neutral
• dat jij morgen op tijd bent = puts a bit more emphasis on you

That emphasis might mean things like:

• you, specifically
• maybe in contrast with someone else
• or simply a slightly stronger, clearer tone

So this sentence is not strange, but je would also be common.

Ook means also / too.

In this sentence, it modifies the speaker’s assumption:

• Ik ga er ook van uit ... = I also assume ...

Its position is natural because Dutch places short adverbs like ook fairly early in the clause, usually after the subject and finite verb or around the middle area of the sentence.

Depending on context, moving ook can slightly change what is emphasized. But here the meaning is most likely:

• I, too, am assuming that you’ll be on time tomorrow for the meeting.

Because op tijd is the normal Dutch expression for on time.

• op tijd = on time, not late
• te laat = too late
• vroeg = early

So:

• morgen op tijd bent = are on time tomorrow

This is just an idiomatic expression you should learn as a set phrase.

Voor here means for in the sense of for the meeting / with regard to the meeting.

• op tijd voor het overleg = on time for the meeting

This is the normal way to say someone is on time for an event.

Other prepositions would change the meaning:

• bij het overleg = at the meeting
• naar het overleg = to the meeting

So if the focus is punctuality in relation to the meeting, voor is the right choice.

Both can refer to a meeting, but they are not always identical.

• vergadering usually means a more formal meeting
• overleg often suggests discussion, consultation, or coordination

So het overleg can sound like:

• a discussion meeting
• a planning talk
• a work consultation

In many contexts, both are possible, but overleg often feels a bit more about talking things through together.

Yes, very common.

It is a standard way to say:

• I assume
• I’m assuming
• I take it for granted that... depending on tone

For example:

• Ik ga ervan uit dat alles in orde is.
• We gaan ervan uit dat ze komt.

It can sound neutral, practical, or slightly firm depending on context.

Yes, sometimes.

Although it often simply means to assume, it can also imply:

• I expect this to be the case
• I’m counting on this

So in some situations, Ik ga ervan uit dat jij morgen op tijd bent may sound a little stronger than a purely neutral assumption. It can suggest:

• the speaker expects punctuality
• the speaker treats it as the normal plan
• perhaps there is some responsibility involved

Tone and context matter a lot here.

The structure is:

• Ik = subject
• ga = finite verb
• er = pronominal element referring to that
• ook = adverb
• van = preposition belonging to the expression
• uit = separable particle
• dat ... = subordinate clause explaining what is being assumed

So the sentence breaks down like this:

• Ik ga er ook van uit
• dat jij morgen op tijd bent voor het overleg.

A useful thing to remember is that the first part is a complete frame:

• Ik ga ervan uit ...

and then the dat-clause tells you what is being assumed.

Yes, very often.

• Ik neem aan dat jij morgen op tijd bent voor het overleg.

This also means I assume that you’ll be on time tomorrow for the meeting.

Compared with Ik ga ervan uit dat...:

• Ik neem aan dat... can sound a bit simpler and more direct
• Ik ga ervan uit dat... can sound a bit more like I’m proceeding on the assumption that...

Both are common, but the nuance is slightly different.
