Η απόδειξη πληρωμής δείχνει τον αριθμό κυκλοφορίας.

Η is the definite article meaning the.

In this sentence, Η απόδειξη πληρωμής means the payment receipt.

A few useful points:

• η is used with feminine singular nouns in the nominative case
• απόδειξη is a feminine noun
• together, η απόδειξη = the receipt

So Η tells you that απόδειξη is the subject of the sentence.

Literally, απόδειξη πληρωμής means receipt of payment.

The word πληρωμής is the genitive singular form of πληρωμή (payment). Greek often uses the genitive where English uses of or a noun used like an adjective.

So:

• η απόδειξη = the receipt
• η πληρωμή = the payment
• απόδειξη πληρωμής = payment receipt / receipt of payment

This is a very common pattern in Greek:

• noun + genitive noun
• like X of Y

Here, πληρωμής tells you what kind of receipt it is.

δείχνει is the 3rd person singular present tense of the verb δείχνω, which means to show, to indicate, or to display.

Because the subject is Η απόδειξη πληρωμής (the payment receipt), which is singular, the verb is also singular:

• δείχνω = I show
• δείχνεις = you show
• δείχνει = he/she/it shows

So here:

• Η απόδειξη πληρωμής δείχνει...
• The payment receipt shows...

Greek often uses the same 3rd person singular form for he/she/it.

Because αριθμό is the direct object of the verb δείχνει.

The subject is:

• Η απόδειξη πληρωμής = the payment receipt

What does it show?

• τον αριθμό κυκλοφορίας = the registration number

In Greek, the direct object usually goes in the accusative case. That is why both the article and the noun change:

• nominative: ο αριθμός = the number
• accusative: τον αριθμό = the number (as object)

So after δείχνει (shows), Greek uses the accusative:

• δείχνει τον αριθμό...

κυκλοφορίας is the genitive singular of κυκλοφορία, which literally relates to circulation, traffic, or being in use/on the road, depending on context.

In the fixed phrase αριθμός κυκλοφορίας, it means:

• registration number
• vehicle registration number
• often understood as license plate number

So although the literal meaning may seem like number of circulation, the natural meaning is registration number.

This is a set phrase worth memorizing:

• αριθμός κυκλοφορίας = registration number / license plate number

For the same basic reason: both are nouns modifying another noun.

Greek often links nouns this way:

• απόδειξη πληρωμής = receipt of payment
• αριθμός κυκλοφορίας = number of registration / registration number

So the structure is:

• η απόδειξη
  • πληρωμής
• τον αριθμό
  • κυκλοφορίας

The second noun gives more information about the first one. English often does this with:

• of
• or noun + noun compounds, like payment receipt

Greek commonly uses the genitive instead.

Greek shows this through case endings and articles, not just word order.

In this sentence:

• Η απόδειξη πληρωμής is in the nominative → subject
• τον αριθμό κυκλοφορίας is in the accusative → direct object

That is signaled by the articles:

• η = nominative feminine singular
• τον = accusative masculine singular

So even if you are still learning the endings, the articles help a lot.

Very roughly:

• η απόδειξη = the receipt → subject
• τον αριθμό = the number → object

Yes. Greek word order is more flexible than English because case endings show grammatical roles.

The neutral order here is:

• Η απόδειξη πληρωμής δείχνει τον αριθμό κυκλοφορίας.

But Greek could also move things around for emphasis, for example:

• Τον αριθμό κυκλοφορίας δείχνει η απόδειξη πληρωμής.

That would still mean essentially the same thing, though the emphasis changes.

For learners, it is best to remember the standard order first:

• subject + verb + object

Usually yes, but depending on context it can also mean:

• indicates
• displays
• states

So in a practical context, this sentence could be understood as:

• The payment receipt shows the registration number
• The payment receipt indicates the registration number
• The payment receipt displays the registration number

The best English choice depends on the situation, but shows is the most direct and natural.

A few notes:

• η sounds like ee
• οι / ει / η / ι / υ often sound like ee in Modern Greek
• χ in δείχνει and κυκλοφορίας is not an English h; it is a rough sound, like the ch in German Bach or Scottish loch
• stress matters a lot in Greek:
  • απόδειξη
  • πληρωμής
  • δείχνει
  • αριθμό
  • κυκλοφορίας

Listening to native audio is especially useful for words like δείχνει and κυκλοφορίας.

Here are the dictionary forms:

• η απόδειξη = receipt
• η πληρωμή = payment
• δείχνω = to show
• ο αριθμός = number
• η κυκλοφορία = circulation, traffic, registration/use on the road

And here are the forms used in the sentence:

• Η απόδειξη → nominative singular
• πληρωμής → genitive singular
• δείχνει → 3rd person singular present
• τον αριθμό → accusative singular
• κυκλοφορίας → genitive singular

Seeing both the dictionary form and the sentence form is a very useful habit when learning Greek.

Most often, yes. In everyday Greek, αριθμός κυκλοφορίας usually refers to a vehicle’s registration number, often what English speakers casually call the license plate number.

So if you see this phrase on a form, receipt, or official document, it is usually asking for or referring to the vehicle’s registration details.

That said, the exact English translation can vary by country:

• registration number
• license plate number
• vehicle registration number

All are good context-based translations.
