Βέβαια θέλω να έρθω, αλλά πρώτα πρέπει να τελειώσω τη δουλειά μου.

Βέβαια means something like of course, certainly, or sure.

In this sentence, it shows clear agreement or willingness:

• Βέβαια θέλω να έρθω = Of course I want to come

It is a very common conversational word. Depending on tone, it can sound:

• warm and natural: Of course
• firm: Certainly
• sometimes slightly emphatic: Yes, definitely

So here it reassures the listener before introducing the problem with αλλά (but).

In Greek, verbs like θέλω (I want) are normally followed by να plus another verb.

So:

• θέλω να έρθω = I want to come
• literally, this is something like I want that I come, but you should think of it as the normal Greek way to say want to + verb

This is very common:

• Θέλω να φύγω = I want to leave
• Θέλω να δω = I want to see

English uses the infinitive (to come), but Modern Greek does not use an infinitive in the same way. Instead, it uses να + a finite verb form.

This is about aspect, which is very important in Greek.

• έρθω is the perfective form
• έρχομαι is the imperfective form

After θέλω να, Greek often chooses between these depending on how the action is viewed.

Here, να έρθω means to come as a single whole event:

• I want to come = I want to arrive / be there

If you said θέλω να έρχομαι, it would usually suggest something repeated or ongoing, more like:

• I want to be coming
• I want to come regularly

So in this sentence, να έρθω is the natural choice because coming is seen as one complete action.

πρέπει να means must, have to, or need to.

So:

• πρέπει να τελειώσω = I must finish / I have to finish

A few useful points:

• πρέπει does not change for person the way many verbs do
• it is followed by να
  • verb

Examples:

• Πρέπει να φύγω = I have to leave
• Πρέπει να διαβάσεις = You must study

In your sentence, πρώτα πρέπει να τελειώσω τη δουλειά μου means:

• first I have to finish my work

Because πρέπει also requires να before the next verb.

So the sentence has:

• θέλω να έρθω
• πρέπει να τελειώσω

This is completely normal in Greek. Different verbs and expressions often introduce another verb with να.

You can think of να as a very common marker before a dependent verb:

• want to come
• must finish
• can go
• hope to see

So seeing να more than once in one sentence is not strange at all.

τελειώσω is the perfective subjunctive-type form used after να.

Here it means finish as a complete action:

• πρέπει να τελειώσω τη δουλειά μου = I have to finish my work

Greek often uses the perfective form after να when the action is seen as complete or one-time.

Compare:

• να τελειώσω = to finish, complete it
• να τελειώνω = more like to be finishing, to finish regularly, or focusing on the process/habit

In this sentence, the speaker means they need to complete the job/work first, so τελειώσω is the natural form.

Because δουλειά is the object of the verb τελειώσω.

• η δουλειά = the work as the subject form
• τη δουλειά = the work as the object form

Greek articles change with case. Here you need the accusative because the speaker is finishing the work.

So:

• η δουλειά είναι δύσκολη = the work is difficult
  (η δουλειά = subject)
• τελειώνω τη δουλειά = I finish the work
  (τη δουλειά = object)

In Greek, possessive words like μου (my) usually come after the noun.

So:

• η δουλειά μου = my work
• literally: the work my

This is the normal Greek pattern:

• το σπίτι μου = my house
• ο φίλος μου = my friend
• η μητέρα μου = my mother

In your sentence:

• τη δουλειά μου = my work

This is one of the biggest word-order differences from English.

Greek often uses the definite article where English might not focus on it as much.

• τη δουλειά μου = my work
• literally the work my

With possessives, the article is usually present:

• το βιβλίο μου = my book
• η ιδέα μου = my idea

Sometimes Greek can omit the article in certain expressions or styles, but in a normal sentence like this, τη δουλειά μου is the expected form.

πρώτα means first.

It tells us the order of actions:

1. finish the work
2. then come

So:

• αλλά πρώτα πρέπει να τελειώσω τη δουλειά μου = but first I have to finish my work

It is functioning as an adverb here.

You will often hear:

• Πρώτα θα φάμε = First we’ll eat
• Πρώτα διάβασε = Read first

Yes, Greek word order is more flexible than English, but this version is very natural and clear.

The sentence is organized like this:

• Βέβαια = sets the tone: of course
• θέλω να έρθω = main idea: I want to come
• αλλά = contrast: but
• πρώτα πρέπει να τελειώσω τη δουλειά μου = obstacle/condition: first I have to finish my work

Other word orders are possible for emphasis, for example:

• Βέβαια, θέλω να έρθω, αλλά πρέπει πρώτα να τελειώσω τη δουλειά μου.
• Θέλω βέβαια να έρθω, αλλά πρώτα πρέπει να τελειώσω τη δουλειά μου.

These are understandable, but the original sounds very natural in everyday speech.

θέλω usually means I want, but in real Greek it can sound quite natural and not necessarily too strong.

In this sentence:

• θέλω να έρθω = I want to come

Depending on context, English might also translate it as:

• I’d like to come

So although the basic meaning is want, the tone can be softer than English I want sometimes sounds.

The stressed syllables are:

• Βέβαια → VÉvea
• θέλω → THÉlo
• έρθω → ÉRtho
• αλλά → aLÁ
• πρώτα → PRÓta
• πρέπει → PRÉpi
• τελειώσω → te liÓso
• δουλειά → dou liÁ
• μου is unstressed

A natural rhythm would be:

Βέβαια θέλω να έρθω, αλλά πρώτα πρέπει να τελειώσω τη δουλειά μου.

The comma gives a small pause after έρθω. The sentence often has a slight contrastive emphasis on αλλά πρώτα.

Yes. δουλειά can mean:

• work
• job
• task/business, depending on context

In this sentence, να τελειώσω τη δουλειά μου most naturally means:

• finish my work
• or finish what I’m working on

It does not necessarily mean permanent employment here. It usually refers to the work the speaker still has to complete before coming.
