Υπέβαλα την αίτηση αποζημίωσης.

Υπέβαλα is first person singular aorist active of υποβάλλω.

That means:

• first person singular = I
• aorist = a completed action in the past
• active = the subject performs the action

So grammatically, it is the normal past form for one completed act of submitting.

Greek often leaves out subject pronouns when they are clear from the verb ending.

Here, the ending -α in υπέβαλα already shows that the subject is I, so εγώ is unnecessary unless you want special emphasis, contrast, or clarification.

Compare:

• Υπέβαλα την αίτηση αποζημίωσης. = neutral
• Εγώ υπέβαλα την αίτηση αποζημίωσης. = emphasizes I

The dictionary form is υποβάλλω.

It looks quite different because this verb forms its aorist in a way learners usually have to memorize:

• υποβάλλω = present
• υπέβαλα = aorist

This happens because the verb is built from βάλλω, whose aorist is έβαλα. With the prefix υπο-, the past form becomes υπέβαλα.

So this is a good verb pair to learn together:

• υποβάλλω
• υπέβαλα

Greek uses the definite article very often, especially when referring to a specific thing.

Here, την αίτηση refers to a particular application or claim, not just any application in general. In official or bureaucratic Greek, using the article here is very natural.

Την is the full accusative singular feminine article.

In everyday speech, the final -ν can sometimes drop, giving τη, but before a vowel it is normally kept. Since αίτηση begins with a vowel sound, την αίτηση is the expected form.

So:

• την αίτηση = standard and natural
• τη αίτηση = not the normal form here

Because many feminine nouns in -η or -ση have the same form in the nominative and accusative singular.

So you get:

• η αίτηση = nominative
• την αίτηση = accusative

The noun itself stays the same, but the article shows the case difference.

Greek often connects two nouns by putting the second one in the genitive.

So αίτηση αποζημίωσης is a standard noun + genitive structure. It means that αποζημίωσης depends on αίτηση and specifies what kind of application or claim it is.

The base form is:

• η αποζημίωση = nominative

The form used here is:

• της αποζημίωσης = genitive singular

In the sentence, only the noun appears, but it is still in the genitive:

• αποζημίωσης

In Greek, the second noun in a noun + genitive phrase often appears without an article when it names the type, category, or purpose of the first noun.

So αίτηση αποζημίωσης is a normal compact phrase.

If you added the article and said της αποζημίωσης, it would usually sound more like you mean a particular compensation already known in the conversation.

Yes, Υπέβαλα την αίτηση αποζημίωσης sounds neutral to formal and is very natural in administrative, legal, insurance, or official contexts.

You could also say έκανα αίτηση για αποζημίωση, which is perfectly normal Greek, but the nuance is a bit different:

• υπέβαλα την αίτηση focuses on the act of submitting the application/claim
• έκανα αίτηση focuses more on making / filing an application

For official paperwork, υπέβαλα την αίτηση αποζημίωσης sounds especially natural.

Yes. Greek word order is flexible, and changing it usually changes the emphasis, not the basic meaning.

• Υπέβαλα την αίτηση αποζημίωσης. = neutral
• Την αίτηση αποζημίωσης υπέβαλα. = emphasizes the claim/application

For learners, the original version is the safest and most neutral choice.

A useful rough guide is:

• Υπέβαλα = ee-PE-va-la
• την αίτηση = teen EH-tee-see
• αποζημίωσης = a-po-zee-MEE-o-sees

Stress falls on:

• πέ in Υπέβαλα
• αί in αίτηση
• μί in αποζημίωσης

A more compact pronunciation guide is:

ee-PE-va-la teen EH-tee-see a-po-zee-MEE-o-sees
