Υπέβαλα αίτηση αποζημίωσης μαζί με μαρτυρία και αποδεικτικά στοιχεία.

Υπέβαλα comes from the verb υποβάλλω, which means to submit or to file in formal contexts.

Here it is in the aorist, first person singular, so it means I submitted as one completed action in the past.

A useful comparison:

• υποβάλλω = I submit / I am submitting
• υπέβαλα = I submitted
• θα υποβάλω = I will submit

So the sentence describes a completed act of filing the application.

Αίτηση is the direct object of Υπέβαλα, so it is in the accusative singular.

For this noun, the nominative and accusative singular look the same:

• nominative: η αίτηση
• accusative: την αίτηση

That is why you do not see a different ending here. The form changes more clearly in the genitive:

• της αίτησης

Because αποζημίωσης is in the genitive singular.

The base noun is:

• η αποζημίωση = compensation

In the phrase αίτηση αποζημίωσης, the genitive shows what kind of application it is:

• an application for compensation
• a compensation claim

This is a very common Greek pattern:

• αίτηση εργασίας = job application
• άδεια οδήγησης = driving licence
• σύμβαση εργασίας = employment contract

So αποζημίωσης depends on αίτηση.

Greek often omits the article in formal or bureaucratic language, especially when talking about actions like filing, submitting, or presenting documents.

So Υπέβαλα αίτηση αποζημίωσης is a natural formal way to say that the speaker submitted a compensation claim.

Other possibilities are also possible, but they mean slightly different things:

• Υπέβαλα την αίτηση αποζημίωσης = I submitted the compensation claim, a specific one
• Υπέβαλα μια αίτηση αποζημίωσης = I submitted a compensation claim, more explicitly indefinite

Without the article, the sentence sounds concise and administrative.

Yes. Κάνω αίτηση is very common and natural in everyday Greek.

So:

• Έκανα αίτηση αποζημίωσης is a normal spoken alternative
• Υπέβαλα αίτηση αποζημίωσης sounds more formal, official, or bureaucratic

Both are correct, but υπέβαλα fits especially well in contexts like insurance, legal claims, government forms, and official complaints.

Yes. Μαζί με is a very common expression meaning together with, along with, or simply with in the sense of accompaniment.

Examples:

• Ήρθε μαζί με την αδελφή του = He came with his sister
• Υπέβαλα την αίτηση μαζί με τα έγγραφα = I submitted the application along with the documents

In your sentence, it introduces the extra material that was submitted together with the application.

Με takes the accusative.

So in this sentence:

• μαρτυρία is accusative singular
• αποδεικτικά στοιχεία is accusative plural

However, these forms happen to look the same as the nominative:

• η μαρτυρία → τη μαρτυρία
• τα στοιχεία → τα στοιχεία

That is why the case is not obvious just from the endings.

Here μαρτυρία means something like testimony, witness statement, or evidence from a witness.

It does not mean the person who witnessed something. The person is:

• ο μάρτυρας = witness

So:

• μαρτυρία = testimony / statement
• μάρτυρας = witness

In this sentence, μαρτυρία is one of the supporting items submitted with the claim.

Because this is a standard Greek expression for supporting evidence or documentary evidence.

Literally:

• αποδεικτικά = proving / evidentiary
• στοιχεία = elements / items / pieces of information

So Greek often thinks of evidence as separate items or pieces, which is why the plural is natural.

You can also have the singular:

• αποδεικτικό στοιχείο = a piece of evidence

But in official language, the plural αποδεικτικά στοιχεία is extremely common.

Αποδεικτικά is an adjective, and it agrees with στοιχεία in gender, number, and case.

• στοιχεία is neuter plural
• so the adjective is also neuter plural: αποδεικτικά

Singular and plural comparison:

• αποδεικτικό στοιχείο = one piece of evidence
• αποδεικτικά στοιχεία = pieces of evidence / supporting evidence

This kind of adjective-noun agreement is a basic and very important feature of Greek.

For the same general reason as with αίτηση: the sentence is using a concise, formal, list-like style.

So μαζί με μαρτυρία και αποδεικτικά στοιχεία sounds like an administrative description of what was submitted.

If the speaker meant specific, already known items, articles would be very natural:

• μαζί με τη μαρτυρία και τα αποδεικτικά στοιχεία

Without articles, the phrase sounds more general and document-like.

Yes. Greek word order is more flexible than English word order.

The original sentence is neutral and very natural:

• Υπέβαλα αίτηση αποζημίωσης μαζί με μαρτυρία και αποδεικτικά στοιχεία.

But you could also move the final phrase for emphasis:

• Μαζί με μαρτυρία και αποδεικτικά στοιχεία, υπέβαλα αίτηση αποζημίωσης.

That version puts more focus on the accompanying material. The meaning stays basically the same.

Yes, it sounds fairly formal and administrative.

The main reasons are:

• υπέβαλα instead of the more everyday έκανα
• αίτηση αποζημίωσης as an official-looking phrase
• αποδεικτικά στοιχεία, which is typical legal or bureaucratic vocabulary

You would expect this kind of sentence in:

• insurance claims
• court or police contexts
• complaints
• government paperwork
• official emails or reports

A rough pronunciation guide is:

i-PE-va-la EH-ti-si a-po-zi-MI-o-sis ma-ZI me mar-ti-RI-a ke a-po-dhi-ktee-KA sti-HIA

Main stress points:

• Υπέβαλα → -πέ-
• αίτηση → αί-
• αποζημίωσης → -μί-
• μαζί → -ζί
• μαρτυρία → -ρί-
• αποδεικτικά → final -κά
• στοιχεία → -χεί-

A few pronunciation notes:

• αι in αίτηση sounds like e
• και is often pronounced ke in normal speech
• χ in στοιχεία is a soft sound before ι, not a hard English k sound
