Returnez produsul defect.

In Romanian, the subject pronoun is often omitted because the verb ending already shows who is doing the action.

• returnez = I return
• The ending -ez tells you it is 1st person singular

So Returnez produsul defect naturally means I return the defective product.

You can add eu if you want emphasis:

• Eu returnez produsul defect. = I am returning the defective product.

Returnez is the 1st person singular present tense form of the verb a returna = to return.

So:

• a returna = to return
• returnez = I return

This present-tense form can often translate into English as either:

• I return
• I am returning

Romanian does not normally use a separate continuous form like English am returning.

Because Romanian usually puts the definite article at the end of the noun instead of using a separate word like English the.

• produs = a product
• produsul = the product

So produsul literally means product-the.

This is one of the most important features of Romanian grammar.

In Romanian, adjectives usually come after the noun.

So:

• produs defect = defective product
• produsul defect = the defective product

This is the normal word order. English usually puts the adjective before the noun, but Romanian often places it after.

Here defect is an adjective meaning defective / faulty.

It agrees with produsul, which is:

• masculine
• singular

So the adjective is also in the masculine singular form:

• produs defect = defective product
• produsul defect = the defective product

A feminine example would look different:

• marfă defectă = defective merchandise

So the ending changes depending on gender and number.

In produsul defect, the noun carries the definite article:

• produsul = the product
• defect = defective

Romanian normally marks definiteness on the noun in this kind of phrase, not on both words.

So:

• produsul defect = the defective product

This is the normal pattern for noun + adjective.

It is grammatically present tense, but in English it can correspond to either:

• I return the defective product
• I am returning the defective product

Romanian does not usually make the same simple-vs.-continuous distinction that English does. Context tells you which English translation sounds best.

Romanian word order is somewhat flexible, but Returnez produsul defect is the most neutral and natural order.

Structure:

• Returnez = verb
• produsul = direct object
• defect = adjective describing the object

If you change the order, it may sound marked, poetic, or unnatural in ordinary speech. For a learner, this sentence is the best standard model to use.

Add nu before the verb:

• Nu returnez produsul defect. = I am not returning the defective product.

This is the normal way to negate a Romanian verb.

A simple learner-friendly pronunciation is roughly:

• reh-too-REHZ

A few useful notes:

• r is usually rolled or tapped
• e is like e in bed
• the stress is on the last syllable: -nez

And the full sentence is roughly:

• reh-too-REHZ პრო-DOO-sul de-FEKT

That is only an approximation, but it is a good starting point.
