Sprzedawca wyceni antyk.

Wyceni is the future tense of the perfective verb wycenić.

In Polish, perfective verbs do not have a true present tense. Their present-looking forms are used to talk about a completed action in the future.

So:

• wycenia = is valuing / values from the imperfective verb wyceniać
• wyceni = will value / will appraise from the perfective verb wycenić

That is why Sprzedawca wyceni antyk means something like The seller will appraise the antique or The seller will put a value on the antique.

The verb wycenić is perfective, which means it presents the action as completed or as a single whole event.

Compare:

• wyceniać = imperfective
  
  • focuses on the process, repetition, or ongoing action
  • Sprzedawca wycenia antyk = The seller is appraising the antique / appraises the antique
• wycenić = perfective
  
  • focuses on reaching the result
  • Sprzedawca wyceni antyk = The seller will appraise the antique / will set a value for it

So the perfective form suggests the seller will finish the valuation, not just be in the middle of doing it.

Antyk is the direct object, so it is in the accusative case. But for many masculine inanimate nouns, the accusative singular is identical to the nominative singular.

So:

• nominative: antyk
• accusative: antyk

That is why the form does not change here.

If the noun were masculine animate, you would often see a different accusative form. For example:

• nominative: kot
• accusative: kota

But with antyk, the form stays the same.

Sprzedawca usually means seller, salesperson, or shop assistant, depending on context.

In this sentence, it could mean:

• a person selling something
• a store employee
• someone dealing in antiques, if the context is an antique shop

Grammatically, sprzedawca is a masculine noun, even though it ends in -a, which can look unusual to English speakers. Polish has a group of masculine nouns like this, especially words for professions or people, for example:

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

Polish does not have articles like English the and a/an.

So Sprzedawca wyceni antyk could mean:

• The seller will appraise the antique
• A seller will appraise an antique

The exact meaning depends on context.

If Polish wants to be more specific, it can use other words, such as:

• ten sprzedawca = this / that seller
• jakiś antyk = some antique

But very often, no article-like word is needed.

Yes. Polish word order is more flexible than English because case endings help show who is doing what.

The neutral order here is:

• Sprzedawca wyceni antyk.

But you could also hear:

• Antyk wyceni sprzedawca.
• Wyceni antyk sprzedawca.

These versions change the emphasis, not the basic meaning.

For example:

• Sprzedawca wyceni antyk = neutral
• Antyk wyceni sprzedawca = emphasis on the antique
• Wyceni antyk sprzedawca = emphasis on the action or a more marked style

A learner should usually start with the neutral subject–verb–object order.

A rough pronunciation is:

vyt-SEH-nee

More precisely:

• w sounds like English v
• y is a Polish vowel with no exact English equivalent; it is not the same as ee
• c before e sounds like ts
• stress in Polish usually falls on the second-to-last syllable

So wyceni is stressed like this:

• wy-CE-ni

And the whole sentence is roughly:

• Sprzedawca wyceni antyk
• shp-sheh-DAFT-sa vyt-SEH-nee AN-tik

That is only an approximation, but it can help at first.

Not quite. They are related in meaning, but not identical.

• wycenić = to price, value, appraise
• ocenić = to assess, judge, evaluate

So:

• Sprzedawca wyceni antyk means the seller will determine its monetary value
• Sprzedawca oceni antyk could mean the seller will assess it more generally, not necessarily give it a price

In the context of objects, antiques, or products, wycenić is the more precise verb if you mean assigning a financial value.

No, not in this exact form.

Because wyceni is perfective, it points to a single completed future action, not a habitual meaning.

If you want a habitual meaning like The salesman values antiques or appraises antiques, Polish would more naturally use the imperfective verb, for example:

• Sprzedawca wycenia antyki.

That means he does it regularly, habitually, or as an ongoing activity.

So:

• wyceni = will appraise once, to completion
• wycenia = appraises / is appraising

In the sentence, antyk is singular and means an antique or the antique.

The plural would be:

• nominative plural: antyki
• accusative plural: antyki for masculine inanimate nouns

So:

• Sprzedawca wyceni antyki. = The seller will appraise the antiques / will appraise antiques

Again, Polish does not use articles, so context tells you whether the meaning is definite or indefinite.

It is grammatically complete and natural, but it does feel a little context-dependent on its own.

A Polish speaker would understand it perfectly, but in real life it often appears in a clearer context, for example:

• Sprzedawca wyceni antyk jutro. = The seller will appraise the antique tomorrow.
• Nasz sprzedawca wyceni ten antyk. = Our seller will appraise this antique.

So the original sentence is correct, but by itself it sounds a bit like a short example sentence used for grammar learning or a simple statement in a larger conversation.
