Το παρκόμετρο δίνει απόδειξη πληρωμής.

Because παρκόμετρο is a neuter singular noun, and το is the neuter singular definite article in the nominative.

So:

• το = the for a neuter singular noun
• παρκόμετρο = parking meter

Together, το παρκόμετρο means the parking meter and functions as the subject of the sentence.

Δίνει is the 3rd person singular present tense of the verb δίνω, which means to give.

So:

• δίνω = I give
• δίνει = he/she/it gives

Here the subject is το παρκόμετρο (it), so δίνει means it gives.

In this kind of context, English often uses issues, provides, or prints rather than the more literal gives.

Greek often leaves out the article in cases where English would naturally use a or where the noun is being used in a more general or functional sense.

So δίνει απόδειξη πληρωμής is natural Greek for something like:

• gives/issues a receipt of payment
• provides proof of payment

If you said μια απόδειξη πληρωμής, that would more explicitly mean a receipt of payment.
If you said την απόδειξη πληρωμής, that would mean the receipt of payment, referring to a specific one.

So the version without an article is very normal here.

Απόδειξη is in the accusative singular because it is the direct object of δίνει.

The verb δίνω takes something that is given. In this sentence, what the meter gives is:

• απόδειξη πληρωμής = proof/receipt of payment

So:

• το παρκόμετρο = subject
• δίνει = verb
• απόδειξη πληρωμής = direct object

Because πληρωμής is the genitive singular form of πληρωμή.

• πληρωμή = payment
• πληρωμής = of payment

Greek commonly uses the genitive to show a relationship like English of.

So:

• απόδειξη πληρωμής literally means proof/receipt of payment

This is a very common noun + genitive structure in Greek.

Yes, it is a very natural and common type of expression in Greek.

• απόδειξη can mean receipt, proof, or evidence, depending on context.
• πληρωμής specifies what kind of receipt/proof it is: of payment.

So in context, απόδειξη πληρωμής is best understood as something like:

• payment receipt
• proof of payment

Greek often expresses this with noun + genitive, where English may prefer either of or a compound noun.

Literally, δίνει means gives. But in this sentence, the more natural English translation is often:

• issues
• provides
• prints

So although the Greek verb is the everyday verb to give, the meaning in context is more like:

• The parking meter issues a payment receipt
• The parking meter provides proof of payment

This is very common in Greek: a basic verb like δίνω can be translated less literally depending on context.

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

The neutral, straightforward order here is:

• Το παρκόμετρο δίνει απόδειξη πληρωμής.

But other orders are possible for emphasis, such as:

• Απόδειξη πληρωμής δίνει το παρκόμετρο.

That would sound more marked and would emphasize proof of payment.

So the original order is the most neutral and natural for a simple statement.

A rough pronunciation guide is:

to par-KO-me-tro THEE-ni a-PO-thee-ksee plee-ro-MEES

A few useful points:

• δ sounds like the th in this
• θ would be the th in thin, but this sentence has δ, not θ
• ει in δίνει sounds like ee
• the stress marks show which syllable is stressed:
  • παρκόμετρο
  • δίνει
  • απόδειξη
  • πληρωμής

It is basically a borrowed/adapted word, built from the idea of parking meter and shaped to fit Greek pronunciation and grammar.

What matters for a learner is that it behaves like a normal Greek neuter noun ending in -ο:

• το παρκόμετρο = the parking meter

So even if its origin feels foreign, grammatically it works just like many ordinary Greek neuter nouns.
