من با کارت پول دادم و رسید را نگه داشتم.

Yes. In Persian, the verb already tells you the subject.

• دادم = I gave / I paid
• داشتم in نگه داشتم = first person singular as part of the verb to keep

So من is often optional. The sentence could naturally be:

با کارت پول دادم و رسید را نگه داشتم.

Adding من can give a little extra emphasis or clarity, similar to saying I in English when you want to stress who did it.

Because Persian uses با for instruments and means of doing something.

So:

• با کارت = with a card / by card
• با ماشین = by car
• با دست = with the hand

This is very normal Persian usage. English often says by card, while Persian says literally with card.

Here کارت means a payment card, such as a:

• bank card
• debit card
• credit card

Which exact kind of card is meant depends on context. In everyday Persian, کارت by itself is often enough if everyone understands it is a bank/payment card.

Persian does not use articles the same way English does.

• There is no obligatory word for the
• Indefiniteness can be shown, but often does not need to be
• Possession can be added if needed

So کارت can mean:

• a card
• the card
• my card

depending on context.

If you want to be explicit, you can say:

• یک کارت = a card
• کارتم or کارتِ من = my card

For رسید را, the را helps show that the receipt is a specific object, so English usually translates it as the receipt.

Yes, literally it is I gave money, but this is a common and natural way to say I paid.

So:

• پول دادم = I paid

This is an everyday expression. A more formal alternative is:

• پرداخت کردم = I made a payment / I paid

So the sentence could also be said more formally as:

با کارت پرداخت کردم و رسید را نگه داشتم.

But پول دادم is very common in normal speech.

دادم is the simple past, first person singular, of دادن (to give).

Breakdown:

• verb: دادن
• past stem: داد
• ending for I: -م

So:

• دادم = I gave

In this sentence, because it appears in the expression پول دادن, it means I paid.

را marks a specific direct object.

So:

• رسید را = the receipt / that specific receipt

It tells you that the speaker is referring to a particular receipt, not just any receipt in general.

A very common spoken form is:

• رو instead of را

So in conversation, many speakers would say:

رسید رو نگه داشتم.

That is the same meaning, just more colloquial.

Good question. Here نگه داشتم is a compound verb.

The full verb is:

• نگه داشتن = to keep, to hold onto

In many Persian compound verbs, one part stays fixed and the other part is the part that gets conjugated.

So here:

• نگه = fixed part
• داشتم = conjugated part

Together:

• نگه داشتم = I kept

So even though داشتم by itself can mean I had, in this compound it is part of the verb نگه داشتن and should be understood as a whole.

Persian is generally subject–object–verb.

This sentence follows that pattern quite well:

• من = subject
• با کارت = prepositional phrase showing means/instrument
• پول = object
• دادم = verb
• و = and
• رسید را = object
• نگه داشتم = verb

So the structure is roughly:

I + with card + money + gave + and + the receipt + kept

That may feel backward compared with English, but it is normal in Persian for the verb to come at the end of the clause.

Yes, it sounds natural and understandable.

A few common variations are:

• با کارت پول دادم و رسید را نگه داشتم.
• با کارت پول دادم و رسید رو نگه داشتم. → more conversational
• با کارت پرداخت کردم و رسید را نگه داشتم. → more formal

Also, in everyday speech, many speakers would drop من unless they want emphasis:

• با کارت پول دادم و رسید رو نگه داشتم.

That is very natural spoken Persian.
