Sprzedawca wycenił i owinął reprodukcję.

Reprodukcję is in the accusative singular. It is the direct object of both verbs: wycenił and owinął.

The basic dictionary form is reprodukcja.
Because it is a feminine noun ending in -a, its accusative singular usually changes to -ę:

• nominative: reprodukcja
• accusative: reprodukcję

So the sentence uses reprodukcję because it means the reproduction as the thing being priced and wrapped.

They are both past tense, 3rd person singular masculine forms.

The subject is sprzedawca (salesman / shop assistant / seller), which is a masculine noun, so the verbs agree with it:

• wycenił = he priced / appraised
• owinął = he wrapped

If the subject were feminine, the forms would be:

• wyceniła
• owinęła

If it were plural masculine personal, you would get:

• wycenili
• owinęli

Yes. Sprzedawca is a masculine noun despite ending in -a.

Polish has a group of masculine nouns, especially names for people, that end in -a, for example:

• mężczyzna = man
• kolega = male friend / colleague
• sprzedawca = salesman / seller

You can tell it is masculine because it takes masculine agreement, as in:

• Sprzedawca wycenił... not
• Sprzedawca wyceniła...

Wycenić means to assign a price, to price, to value, or to appraise something.

Depending on context, Sprzedawca wycenił... could mean:

• he priced it for sale
• he valued it
• he appraised it

In a shop context, priced is often the most natural translation. In an art or auction context, appraised may also fit well.

This is a matter of aspect.

• wycenił is perfective
• wyceniał is imperfective

In this sentence, wycenił shows the action as completed: he finished pricing it.

By contrast, wyceniał would suggest an ongoing, repeated, or background action:

• Sprzedawca wyceniał reprodukcję. = The seller was pricing the reproduction / used to price it.

The same applies to the second verb:

• owinął = he wrapped it up, completed
• owijał = he was wrapping it / used to wrap it

So this sentence presents two finished actions.

Because the same object belongs to both verbs.

In English we also do this:

• The seller priced and wrapped the reproduction.

Polish works the same way here. Reprodukcję is understood as the object of both:

• wycenił reprodukcję
• owinął reprodukcję

Instead of repeating the noun, Polish simply mentions it once after the coordinated verbs.

Yes. Polish word order is fairly flexible because endings show grammatical roles.

The neutral order here is:

• Sprzedawca wycenił i owinął reprodukcję.

But you could also say:

• Reprodukcję sprzedawca wycenił i owinął.
• Sprzedawca reprodukcję wycenił i owinął.

These alternatives may sound more emphatic or stylistically marked. The original version is the most straightforward and neutral.

Because Polish has no articles like English a/an and the.

So:

• sprzedawca can mean a seller or the seller
• reprodukcję can mean a reproduction or the reproduction

Context tells you which meaning is intended. That is very normal in Polish.

A learner-friendly approximation is:

• wycenił ≈ vuh-TSE-nyiw
• owinął ≈ oh-VEE-nonw (with a nasal sound in the last syllable)

A few helpful points:

• w sounds like English v
• c sounds like ts
• ł sounds like English w
• ą is a nasal vowel; before ł it is often heard roughly like on or ow̃

So:

• wycenił has three syllables: wy-ce-nił
• owinął has three syllables: o-wi-nął

Reprodukcja means reproduction, copy, or print, especially of an artwork, image, or document.

It is a normal Polish word, but it is a bit more specific than a very everyday object word like książka or torba. In many contexts it suggests:

• an art reproduction
• a printed copy of an image
• a replica in some formal sense

So this sentence may sound like something from a shop, gallery, auction house, or museum context.

I simply means and. Polish often avoids unnecessary repetition just like English does.

So instead of saying:

• Sprzedawca wycenił reprodukcję i sprzedawca owinął reprodukcję

Polish naturally says:

• Sprzedawca wycenił i owinął reprodukcję.

This is smoother and completely standard.

Yes. Sprzedawca can be translated in different ways depending on context:

• seller
• salesman
• shop assistant
• sometimes sales clerk

If the context is just a store employee helping a customer, shop assistant may sound most natural in British English, while sales clerk or salesperson may fit some American contexts better.

So the exact best translation depends on the situation, even though the Polish word stays the same.

Yes, it is grammatical and natural.

It is a clear, compact sentence with:

• a masculine singular subject: sprzedawca
• two completed past actions: wycenił i owinął
• one shared direct object in the accusative: reprodukcję

It sounds like a normal narration of what happened: first the seller priced the item, then wrapped it.
