Poate vine Andrei.

Here, poate means maybe / perhaps.

It is not the verb can in this sentence. Romanian poate can be:

• an adverb = maybe, perhaps
• a verb form of a putea = he/she can

In Poate vine Andrei, the meaning is Maybe Andrei is coming / Maybe Andrei will come.

Compare:

• Poate vine Andrei. = Maybe Andrei is coming.
• Andrei poate veni. = Andrei can come.

So context and sentence structure tell you which meaning is intended.

Vine is the 3rd person singular present of a veni (to come).

Romanian often uses the present tense where English might use:

• is coming
• will come
• sometimes even might come

So Poate vine Andrei can mean:

• Maybe Andrei is coming
• Maybe Andrei will come

The exact time depends on context. Romanian does not need a special future form here.

All three are possible translations depending on context.

In Romanian, vine is simply the present tense form, but English usually chooses among several options:

• comes if talking generally
• is coming if it sounds like something happening now or soon
• will come if it refers to the future

With poate, English often sounds most natural with:

• Maybe Andrei is coming
• Maybe Andrei will come

So the Romanian form stays the same, while English translation changes according to context.

Because Romanian often allows — and often prefers — the subject after the verb, especially in sentences like this.

So vine Andrei is a very natural Romanian pattern for Andrei is coming.

Putting Andrei after the verb can:

• sound more natural
• present the action first
• leave the person as the new or important piece of information

In other words, the sentence feels a bit like:

• Maybe the one coming is Andrei.

It does not sound strange in Romanian.

Yes. Poate că vine Andrei is also correct and very common.

The word că here is optional. It introduces the clause, a bit like that in English, although English often leaves that out.

So:

• Poate vine Andrei.
• Poate că vine Andrei.

Both mean the same thing.

A rough difference:

• Poate vine Andrei = slightly shorter, a bit more direct
• Poate că vine Andrei = slightly fuller or more explicit

But both are natural.

You would usually say:

• Andrei poate veni.

Here poate is the verb can, and veni is the infinitive to come.

So compare carefully:

• Poate vine Andrei. = Maybe Andrei is coming.
• Andrei poate veni. = Andrei can come.

This is one of the most important distinctions in this sentence.

Because Romanian usually does not need a subject pronoun when the subject is already clear or explicitly stated.

Since the sentence already has Andrei, there is no need to add el.

Romanian commonly omits subject pronouns unless they are needed for:

• contrast
• emphasis
• clarification

So Poate vine Andrei is perfectly normal, and adding el would usually be unnecessary.

Poate expresses uncertainty. It means the speaker is not sure.

It is like saying:

• maybe
• perhaps

It does not by itself mean the speaker thinks it is very likely.

If you wanted something stronger, Romanian might use a word like probabil (probably).

So:

• Poate vine Andrei. = the speaker is unsure
• Probabil vine Andrei. = the speaker thinks it is more likely

No. Andrei stays the same.

In this sentence, Andrei is simply the subject of vine. Romanian proper names often appear without any visible change in this kind of basic sentence.

So there is nothing special happening to Andrei here grammatically beyond being the person who may be coming.
