Καταγγέλλω το συμβόλαιο πριν τελειώσει η δέσμευση συμβολαίου.

That is a very common question. Καταγγέλλω does often mean report, denounce, or file a complaint against someone or something.

But in legal or contract language, καταγγέλλω ένα συμβόλαιο / μια σύμβαση means terminate, cancel, or give notice to end a contract.

So in this sentence, Καταγγέλλω το συμβόλαιο means:

• I terminate the contract
• or I cancel the contract
• or more formally, I give notice to terminate the contract

It is a more formal/legal verb than the everyday ακυρώνω.

Because it is the direct object of καταγγέλλω.

Greek uses:

• nominative for the subject
• accusative for the direct object

Here:

• Καταγγέλλω = I terminate
• το συμβόλαιο = the contract

So το συμβόλαιο is the thing being terminated, which makes it the direct object.

It can mean either, depending on context.

The Greek present tense often covers both:

• I terminate
• I am terminating

In formal or legal language, the present can also be performative. That means the speaker is doing the action by saying it, similar to English I declare, I resign, I hereby terminate.

So Καταγγέλλω το συμβόλαιο can sound like:

• I am hereby terminating the contract

If you wanted a clear future meaning, you would normally say:

• Θα καταγγείλω το συμβόλαιο = I will terminate the contract

Because after πριν meaning before, Greek normally uses the subjunctive for an event that is expected, planned, or not yet completed at the reference point.

Here, τελειώσει is the form used to mean:

• before it ends
• before it is finished

So:

• πριν τελειώσει η δέσμευση συμβολαίου = before the contract commitment ends

This is a very typical Greek structure:

• πριν φύγει = before he/she leaves
• πριν αρχίσει = before it starts
• πριν λήξει = before it expires

Because after πριν, Greek often uses the subjunctive with or without να.

So both of these are possible:

• πριν τελειώσει
• πριν να τελειώσει

In modern Greek, πριν τελειώσει is very common and natural.

So even though τελειώσει is a subjunctive form, you do not have to show να explicitly after πριν.

Τελειώσει is the 3rd person singular aorist subjunctive of τελειώνω.

In this sentence, it does not mean past tense. That is important.

Here it expresses an action viewed as a whole, with emphasis on its endpoint:

• να τελειώσει = to end / to finish
• πριν τελειώσει = before it ends

Greek often uses this perfective/aorist subjunctive after πριν when the idea is reaching an endpoint.

That is why τελειώσει fits well: the sentence is talking about the moment when the commitment period comes to an end.

The subject is η δέσμευση συμβολαίου.

So the structure is:

• πριν τελειώσει = before ends
• η δέσμευση συμβολαίου = the contract commitment / binding period

In more natural English order:

• before the contract commitment ends

Notice the contrast:

• Εγώ am the understood subject of καταγγέλλω
• η δέσμευση συμβολαίου is the subject of τελειώσει

So the two clauses have different subjects.

Both are possible, but they feel slightly different.

• η δέσμευση συμβολαίου is more compact and a bit more formal or bureaucratic
• η δέσμευση του συμβολαίου sounds a bit more explicit and often more natural in everyday speech

The word συμβολαίου is in the genitive, showing a relationship like:

• contract commitment
• commitment of the contract
• contractual commitment

So the genitive here works like a modifying noun.

In many real-life contexts, Greek speakers might prefer something like:

• η δέσμευση του συμβολαίου
• η περίοδος δέσμευσης
• η συμβατική δέσμευση

It is understandable, but it sounds somewhat formal and a little repetitive because it has both συμβόλαιο and συμβολαίου close together.

A more idiomatic version might be:

• Καταγγέλλω το συμβόλαιο πριν λήξει η δέσμευση.
• Καταγγέλλω το συμβόλαιο πριν λήξει η περίοδος δέσμευσης.
• Καταγγέλλω το συμβόλαιο πριν λήξει η συμβατική δέσμευση.

Also, with contracts, Greek very often uses λήγω / λήξει for expire, so πριν λήξει can sound more natural than πριν τελειώσει in this kind of context.

These words are related, but they are not identical.

• συμβόλαιο = contract, often the everyday word
• σύμβαση = contract/agreement, often more formal or legal
• δέσμευση = commitment, binding obligation, or minimum commitment period, depending on context

So in this sentence:

• το συμβόλαιο is the contract itself
• η δέσμευση συμβολαίου refers to the binding period or obligation connected to that contract

For example, in phone or internet contracts, δέσμευση often means the minimum period during which you are tied to the agreement.

The tricky part is γγ.

In modern Greek, γγ is usually pronounced roughly like ng in finger, not like the g in ginger.

So καταγγέλλω sounds approximately like:

• κα-τα-ng-E-lo

with the stress on -γγέ-.

A simple stress guide for the sentence:

• καταγγέλλω
• συμβόλαιο
• πριν
• τελειώσει
• δέσμευση
• συμβολαίου

That pronunciation is enough for a learner, even if a native speaker makes the γγ sound a bit more specifically Greek.
