Αμφισβητώ τη χρέωση.

Because Greek often drops the subject pronoun when it is clear from the verb ending.

• Αμφισβητώ means I dispute / I challenge
• The ending -ώ already tells you the subject is I

So Εγώ αμφισβητώ τη χρέωση is possible, but usually εγώ is omitted unless you want emphasis, such as I am disputing it, not someone else.

Αμφισβητώ means I dispute, I challenge, or I contest.

In this sentence, it is commonly used in situations like:

• disputing a bank charge
• contesting a bill
• challenging whether a charge is valid

So it is a good match for formal or practical situations involving payments, fees, or billing.

It is:

• present tense
• first person singular
• active voice

So literally it is I dispute or I am disputing, depending on context.

A few related forms are:

• αμφισβητώ = I dispute
• αμφισβητείς = you dispute
• αμφισβητεί = he/she/it disputes
• αμφισβητούμε = we dispute

This is one of the common Greek verbs that end in -ώ in the first person singular.

Because χρέωση is the direct object of the verb, and Greek normally uses the article here.

• η χρέωση = the charge, the billing, the debit
• τη χρέωση = the charge in the accusative case

So:

• Αμφισβητώ τη χρέωση = I dispute the charge

Leaving out the article would sound less natural in most ordinary contexts.

This is about the final -ν of the feminine accusative article.

Both τη and την exist, but in modern Greek the final -ν is often dropped before certain consonants. Since χρέωση begins with χ, it is very common to say and write:

• τη χρέωση

You may also see:

• την χρέωση

But τη χρέωση is the more typical form here.

A useful rule of thumb: the final -ν is usually kept before vowels and certain consonants, but it is often dropped before others.

Because many feminine nouns of this type have the same form in the nominative and accusative singular.

Here you have:

• η χρέωση = nominative
• τη χρέωση = accusative

So the article changes, but the noun itself stays the same.

This is very common in nouns ending in -ση, such as:

• η χρήση / τη χρήση
• η λύση / τη λύση

Χρέωση usually means something like:

• charge
• billing
• debit
• sometimes fee, depending on context

In financial contexts, it often refers to an amount charged to your account or card.

So in a sentence like this, the meaning is usually something like I dispute the charge or I contest the billing.

A simple English-friendly approximation is:

am-feez-vee-TO tee HRE-o-see

A few pronunciation notes:

• θ sounds like th in think
• χ sounds like a rough h/k sound, like the ch in Scottish loch or German Bach
• the stress falls on the last syllable of αμφισβητώ
• the stress in χρέωση falls on χρέ

So the rhythm is roughly:

am-fiz-vi-TO ti HRE-o-si

Yes. Greek word order is more flexible than English.

The neutral, straightforward order here is:

• Αμφισβητώ τη χρέωση.

But you could also say:

• Τη χρέωση αμφισβητώ.

That version puts more emphasis on the charge.

So the original sentence is the most natural neutral version, but Greek allows movement for emphasis more easily than English does.

It sounds fairly natural, but also a bit formal/practical, especially in customer-service, legal, or banking contexts.

It is the kind of sentence you might use:

• in a complaint
• with a bank
• in writing
• in a customer support conversation

In more casual speech, people might use other phrasing depending on the situation, but Αμφισβητώ τη χρέωση is perfectly normal and useful.

Yes, but it does not mean exactly the same thing.

• Αμφισβητώ τη χρέωση = I dispute / contest the charge
• Δεν συμφωνώ με τη χρέωση = I do not agree with the charge

The first one sounds stronger and more official, as if you are formally challenging it.
The second one is softer and more general.

So if you are making an actual dispute, Αμφισβητώ τη χρέωση is the better choice.
