Πιστώνω τον λογαριασμό.

In Greek, the verb ending often already tells you who the subject is.

• Πιστώνω = I credit
• The ending -ω usually marks 1st person singular in the present tense.

So Greek normally does not need the subject pronoun εγώ for I unless you want emphasis.

• Πιστώνω τον λογαριασμό. = I credit the account.
• Εγώ πιστώνω τον λογαριασμό. = I credit the account.
  (This sounds more emphatic, like contrasting I with someone else.)

Πιστώνω is present tense, active voice, 1st person singular.

Depending on context, the Greek present can correspond to different English present meanings, such as:

• I credit the account
• I am crediting the account
• sometimes even a habitual sense, like I credit accounts in the right context

So Greek present tense is often a bit broader than a single English form.

Because λογαριασμό is the direct object of the verb, so it takes the accusative case, not the nominative.

Here is the pattern:

• ο λογαριασμός = the account as a subject
• τον λογαριασμό = the account as an object

In this sentence:

• Πιστώνω = verb
• τον λογαριασμό = the thing being credited, so it is the object

That is why both the article and the noun change:

• ο → τον
• λογαριασμός → λογαριασμό

The dictionary form is ο λογαριασμός.

Greek dictionaries usually list nouns in the nominative singular, together with the article, so you would look up:

• ο λογαριασμός

In the sentence, it appears as:

• τον λογαριασμό

because it is in the accusative singular.

Greek uses the definite article very often, and in this sentence τον λογαριασμό means the account, referring to a specific account.

Compare:

• Πιστώνω τον λογαριασμό. = I credit the account.
• Πιστώνω έναν λογαριασμό. = I credit an account.

Saying Πιστώνω λογαριασμό without an article is generally less neutral and would not be the normal basic way to say it in most contexts.

A good approximate pronunciation is:

• pee-STO-no ton lo-gha-rya-SMO

More carefully in Modern Greek IPA:

• [piˈstono ton loɣarjaˈsmo]

A few points:

• ώ in Πιστώνω shows the stress: pi-STO-no
• ό in λογαριασμό shows the stress: lo-gha-rya-SMO
• γ before α here sounds like a soft voiced sound, roughly like a smooth gh in lo-gha-...

No, Greek word order is more flexible than English word order, because case endings help show what each word is doing.

The neutral order here is:

• Πιστώνω τον λογαριασμό.

But other orders are possible for emphasis, for example:

• Τον λογαριασμό πιστώνω.
  This puts extra focus on the account.

Even though the order can change, the accusative form τον λογαριασμό still marks it as the object.

It is a real and useful verb, but it is somewhat formal, financial, or technical in many contexts.

It is commonly used in banking, accounting, billing, and similar situations, where it means things like:

• to credit
• to post a credit to
• to add an amount to an account

So a learner may meet it especially in financial language rather than in casual everyday conversation.

It is a verb. The basic form is πιστώνω.

Many Greek verbs in -ώνω belong to a recognizable verb pattern. In this sentence, you only need to know that:

• πιστώνω = present tense base form for I credit

If you later learn more forms, you may see things like other persons and tenses built from the same stem.

Yes, absolutely.

Greek often drops subject pronouns because the verb ending already shows the subject. But you can include εγώ if you want emphasis or contrast.

• Πιστώνω τον λογαριασμό. = neutral
• Εγώ πιστώνω τον λογαριασμό. = I credit the account
  (implying maybe someone else does not)

So adding εγώ is possible, but not necessary in a neutral statement.

Stress is very important in Greek and is written clearly.

• Πιστώνω has stress on τώ
• λογαριασμό has stress on the final μό

That means you should say:

• pi-STO-no
• lo-gha-rya-SMO

Greek stress is not optional decoration; it is part of the word and should be learned together with the vocabulary item.

You would normally put δεν before the verb:

• Δεν πιστώνω τον λογαριασμό. = I do not credit the account.

This is the normal way to negate a present-tense statement in Greek.

It can mean more than one thing, depending on context. Common meanings include:

• account
• bill
• sometimes calculation or related ideas in certain contexts

So ο λογαριασμός is a useful word with several meanings. In your sentence, the financial meaning account fits naturally.
