Nu numai că verifică produsul, ci și confirmă rambursarea.

It means not only ... but also ....

In this sentence, the pattern links two actions:

• verifică produsul = checks the product
• confirmă rambursarea = confirms the refund

So the whole sentence says that the subject does one thing and also another thing.

A very close variant is nu doar că ... ci și ..., which means the same thing.

Here, că helps introduce a full clause after nu numai.

That is the normal pattern when what follows is a verb clause:

• Nu numai că verifică produsul, ci și confirmă rambursarea.

Without că, this sentence would sound unnatural in standard Romanian.

Compare:

• Nu numai că verifică produsul... = not only does he/she/it/they check the product...
• Nu numai produsul... = not only the product...

So că is used here because the structure continues with a finite verb, not just a noun phrase.

Ci și is the second half of the correlative pair nu numai ... ci și ....

It corresponds to but also in English.

Romanian often uses ci after a negative first part. In this fixed pattern, ci și is the standard choice:

• nu numai ..., ci și ... = not only ..., but also ...

So in this sentence, ci și introduces the second action that is being added.

Verifică is the present tense form of the verb a verifica = to check / to verify.

In this form, it can mean:

• he checks
• she checks
• it checks
• they check

That happens because, in Romanian, the 3rd person singular and 3rd person plural often look the same in the present tense.

So verifică by itself does not tell you whether the subject is singular or plural; context does.

Romanian often leaves subject pronouns out because the verb usually gives enough information. This is called a pro-drop language.

So instead of saying:

• El verifică produsul
• Ea verifică produsul
• Ei verifică produsul

Romanian can simply say:

• Verifică produsul

In this sentence, the subject is understood from context. The only extra wrinkle is that verifică and confirmă can be either singular or plural in the 3rd person, so context is especially important.

Because -ul is the Romanian definite article attached to the noun.

• produs = product / a product
• produsul = the product

Unlike English, Romanian usually puts the definite article at the end of the noun instead of before it.

So produsul literally means the product.

Because produsul is a direct object, but it is an inanimate noun.

In Romanian, pe is commonly used before direct objects that are:

• people
• animate beings
• highly specific personal objects in certain contexts

For an inanimate noun like produsul, you normally do not use pe.

So:

• verifică produsul = correct
• verifică pe produsul = incorrect

Rambursarea means the refund or the reimbursement.

It comes from:

• rambursare = refund / reimbursement
• rambursarea = the refund / the reimbursement

Just like produsul, it has a definite article attached at the end:

• -a here marks the definite form of this noun

It is definite because the sentence is talking about a specific refund, not just refunds in general.

Yes. Both are in the present indicative, and both are 3rd person singular or plural forms.

• verifică < a verifica
• confirmă < a confirma

This parallel structure is very common in Romanian, especially in a sentence like this where two actions are being coordinated:

• checks the product
• confirms the refund

So grammatically, the sentence is nicely balanced.

Yes, normally yes.

The comma separates the two parts of the structure:

• Nu numai că verifică produsul,
• ci și confirmă rambursarea.

Since these are two coordinated clauses in the not only ... but also ... pattern, the comma is standard and helpful.

Yes, but changing the word order can also change the emphasis.

The original sentence emphasizes two actions:

• checking the product
• confirming the refund

If you changed it to something like:

• Verifică nu numai produsul, ci și rambursarea

that would mean something more like:

• They check not only the product, but also the refund

That version focuses more on the objects being contrasted, not on two separate actions. So the original wording is better if the idea is that the subject performs two different actions.

The letter ă is a very common Romanian vowel. It is a short, neutral sound, similar to the a in English sofa for many speakers.

So roughly:

• că sounds a bit like kuh
• verifică ends with a soft -kuh
• confirmă ends with a soft -muh

This is only an approximation, but it is a good starting point for English speakers. The important thing is that ă is different from a.
