Εσείς είστε εδώ αύριο;

Yes, είστε already tells you the subject is you (plural or formal singular), so εσείς is not strictly necessary.

Greek often drops subject pronouns because the verb ending already shows the person and number. So you could also say:

Είστε εδώ αύριο;

Adding εσείς can do things like:

• add emphasis
• create contrast
• make the subject especially clear

For example, it can sound like:

• And you? Will you be here tomorrow?
• You will be here tomorrow, right?

So in this sentence, εσείς is optional, but natural if the speaker wants emphasis.

It can mean either:

• plural you = talking to more than one person
• formal singular you = talking politely to one person

Greek uses:

• εσύ for informal singular you
• εσείς for plural or polite singular you

So without context, Εσείς είστε εδώ αύριο; could be addressed either to:

• one person formally
• several people

This is very common in Greek. The present tense can be used for a future situation, especially when there is a clear time word like αύριο (tomorrow).

So Greek can use the present here in a way that English often uses will for.

This is natural and common in everyday speech. The time expression αύριο already makes the future meaning clear.

A more explicit future version would be:

Θα είστε εδώ αύριο;

Both are possible, but the version without θα is very natural in conversation.

Not necessarily better—just slightly different in feel.

• Εσείς είστε εδώ αύριο; is perfectly natural, especially in conversation.
• Θα είστε εδώ αύριο; makes the future reference more explicit.

Very roughly:

• without θα = often a bit more conversational or immediate
• with θα = clearly marked future

Both can be used to ask the same thing. Context and speaking style matter.

Είστε is the 2nd person plural present form of the verb είμαι (to be).

Here is the present tense:

• είμαι = I am
• είσαι = you are (singular informal)
• είναι = he/she/it is
• είμαστε = we are
• είστε = you are (plural or formal singular)
• είναι = they are

So in this sentence, είστε matches εσείς.

In Greek, the question mark is written as ;

So:

• Greek ; = English ?

That means:

Εσείς είστε εδώ αύριο;

is a question.

This is one of the first punctuation differences Greek learners notice.

Greek word order is more flexible than English word order.

The sentence:

Εσείς είστε εδώ αύριο;

is natural, but other orders are also possible, depending on emphasis:

• Είστε εδώ αύριο;
• Αύριο είστε εδώ;
• Εδώ είστε αύριο; (possible, but depends more on context and emphasis)

The most neutral elements here are:

• είστε = the verb
• εδώ = here
• αύριο = tomorrow

Changing the order usually changes focus or emphasis, not the basic meaning.

Greek often includes location words like εδώ very naturally when talking about presence or availability.

In this sentence, εδώ means here, literally referring to this place. It is not unusual or redundant in Greek.

If the speaker wants to know whether someone will be physically present in this location tomorrow, εδώ is exactly the right word.

Yes, but the meaning would change because you would be removing information.

• Εσείς είστε εδώ; = Are you here?
• Εσείς είστε αύριο; = not natural in the same way; it feels incomplete because αύριο usually needs the rest of the idea to be clear
• Είστε εδώ αύριο; = still natural
• Εσείς είστε εδώ αύριο; = natural, with emphasis on you

So:

• εδώ tells you the place
• αύριο tells you the time

Both are important in the full sentence.

A simple pronunciation guide is:

eh-SEES EE-steh eh-THO AV-ree-oh?

A few helpful notes:

• Εσείς has the stress on the second syllable: -σείς
• είστε has the stress on εί-
• εδώ has the stress on the second syllable: -δώ
• αύριο has the stress on the first syllable: ΑΥ-ριο

Also:

• δ in Modern Greek sounds like th in this
• θ would sound like th in think, but there is no θ in this sentence

You would normally use εσύ and είσαι:

Εσύ είσαι εδώ αύριο;

Or, more commonly without the pronoun:

Είσαι εδώ αύριο;

That is the informal singular version.

So the contrast is:

• Εσείς είστε εδώ αύριο; = formal singular or plural
• (Εσύ) είσαι εδώ αύριο; = informal singular

Yes, it is natural Greek.

A native speaker might also say:

• Θα είστε εδώ αύριο;
• Είστε εδώ αύριο;
• Αύριο θα είστε εδώ;

All of these are possible, depending on context and tone.

Your sentence is especially natural if the speaker is:

• checking someone’s availability
• confirming whether someone will be present
• contrasting you with someone else by using εσείς

So overall, it is a normal and useful sentence pattern.
