Το παρκόμετρο λειτουργούσε, παρόλα αυτά δόθηκε κλήση στάθμευσης.

Παρκόμετρο is a neuter singular noun, so it takes the neuter singular definite article το in the nominative: το παρκόμετρο.

Here it means the parking meter, not a parking meter, because the speaker is referring to a specific meter in the situation.

Λειτουργούσε is the imperfect tense, 3rd person singular, from λειτουργώ.

The imperfect is used for:

• an ongoing action in the past
• a background situation
• something that was in progress

So here, λειτουργούσε suggests that the meter was functioning / was working at that time. It sets the scene.

That contrasts nicely with δόθηκε, which refers to a single completed event.

This is a very common Greek aspect pattern:

• λειτουργούσε = imperfect → ongoing/background past situation
• δόθηκε = aorist passive → one completed event

So the sentence is structured like this:

• background fact: the meter was working
• surprising result: a parking ticket was issued

Greek uses aspect very strongly, so this contrast is natural and important.

Παρόλα αυτά means nevertheless, even so, despite that, or all the same.

It introduces a contrast stronger than simple but. It tells you that the second clause happened in spite of what was stated in the first clause.

So the logic is:

• the meter was working
• despite that, a ticket was still issued

Not exactly.

• αλλά usually just means but
• παρόλα αυτά means nevertheless / even so

So παρόλα αυτά sounds a bit stronger and more explicit. It emphasizes that the second fact is surprising or contrary to expectation.

In this sentence, παρόλα αυτά fits well because getting a ticket seems unfair or unexpected if the meter was working.

You may see both.

• παρ’ όλα αυτά is the more traditional and etymologically transparent spelling
• παρόλα αυτά is extremely common in modern everyday writing

For a learner, the important thing is to recognize that both are used with the same meaning in practice. If you want to be more conservative or formal, παρ’ όλα αυτά is often preferred.

Δόθηκε is the aorist passive of δίνω.

Literally, it means was given, but in this context it is better understood as was issued.

Greek often uses the passive when the person doing the action is:

• unknown
• unimportant
• obvious from context

So the sentence does not focus on the officer or authority who issued the ticket. It focuses on the event itself: a parking ticket was issued.

This is a noun + genitive structure:

• κλήση = ticket, citation, summons, call (depending on context)
• στάθμευσης = of parking, from στάθμευση meaning parking

So κλήση στάθμευσης literally means something like parking citation or ticket of parking, which in natural English is parking ticket.

The genitive στάθμευσης tells you what kind of κλήση it is.

Because it is indefinite here.

Greek often leaves a noun without an article when it means a/an in English. So:

• δόθηκε κλήση στάθμευσης = a parking ticket was issued
• δόθηκε η κλήση στάθμευσης would mean the parking ticket was issued

No article here makes it indefinite and more natural in this context.

Yes. Κλήση has more than one meaning depending on context.

Common meanings include:

• call, especially a phone call
• summons
• citation / ticket

When you add στάθμευσης, the meaning becomes clear: it is a parking ticket.

So this is a good example of how context determines which meaning is intended.

Yes. Greek word order is fairly flexible.

For example, you could also say:

• Παρόλα αυτά, δόθηκε κλήση στάθμευσης.
• Το παρκόμετρο λειτουργούσε. Παρόλα αυτά, δόθηκε κλήση στάθμευσης.

The original version is perfectly natural. The comma before παρόλα αυτά helps mark the contrast clearly.

The sentence sounds neutral and perfectly natural, especially in written language.

A more colloquial alternative might be:

• Το παρκόμετρο δούλευε, παρ’ όλα αυτά μου έκοψαν κλήση.

Differences:

• δούλευε is more everyday than λειτουργούσε
• μου έκοψαν κλήση is a very common colloquial way to say they gave me a ticket

So your original sentence is correct and natural, but slightly more formal or report-like in tone.
