Możesz odesłać towar za darmo.

Możesz is the 2nd person singular form of móc, which means can / to be able to.

So możesz means:

• you can
• you are able to
• sometimes you may, depending on context

In this sentence, it can suggest either:

• ability/possibility: you can do it
• permission/option: you are allowed to do it

Polish often leaves that distinction to context, just like English you can sometimes does.

Because after możesz (you can), Polish normally uses an infinitive.

So the structure is:

• możesz = you can
• odesłać = send back / return

This is the same kind of pattern as in English:

• You can return it
• You can send it back

Other examples:

• Możesz przyjść. = You can come.
• Możesz zadzwonić. = You can call.

Odesłać means to send back.

In shopping or delivery contexts, it often corresponds to English:

• send back
• return

So odesłać towar is literally send the goods back, but in natural English it may simply be translated as return the item/product.

A useful nuance:

• wysłać = send
• odesłać = send back

The prefix od- often adds the idea of movement away/back.

Both can be used in return contexts, but they are not identical.

• odesłać focuses on the action of sending something back
• zwrócić focuses on returning something more generally

So in an online shopping context:

• Możesz odesłać towar za darmo. = You can send the goods back for free.
• Możesz zwrócić towar za darmo. = You can return the goods for free.

If the return specifically involves shipping something back, odesłać feels very natural.

Grammatically, towar is singular. It means goods, merchandise, product, item, depending on context.

Even though English goods is plural in form, Polish towar is often singular when talking about merchandise in a general sense.

So:

• towar = goods / merchandise / item / product
• towary = goods / products / items

In this sentence, towar is a general singular noun, something like:

• the item
• the goods
• the product

The best English translation depends on context.

It is in the accusative case, because it is the direct object of odesłać.

With masculine inanimate nouns like towar, the accusative singular looks the same as the nominative singular:

• nominative: towar
• accusative: towar

So even though the form does not change, its function in the sentence does:

• Towar jest nowy. = The item is new. → nominative
• Możesz odesłać towar. = You can send back the item. → accusative

Za darmo means for free.

It is a very common Polish expression. In this sentence it tells you that returning or sending the item back does not cost anything.

Examples:

• Dostawa jest za darmo. = Delivery is free.
• Możesz to dostać za darmo. = You can get it for free.

A very close alternative is bezpłatnie, which also means free of charge:

• Możesz odesłać towar bezpłatnie.

Nuance:

• za darmo is very common and natural in everyday language
• bezpłatnie can sound a bit more formal or official

Yes. Możesz is 2nd person singular, so it is used when speaking to:

• one person
• in a direct, informal style
• or in customer-facing language where Polish often uses singular you

In advertisements, websites, and instructions, Polish often addresses the customer as singular you, much like English does.

More formal alternatives might use:

• może Pan / może Pani = you can, sir/ma’am
• mogą Państwo = you can, ladies and gentlemen / you all (formal)

So this sentence is normal for a website or shop message directed at one customer in a general way.

Yes. Polish word order is fairly flexible, although some versions sound more natural in specific contexts.

The original:

• Możesz odesłać towar za darmo.

Other possible orders:

• Towar możesz odesłać za darmo.
• Za darmo możesz odesłać towar.
• Możesz za darmo odesłać towar.

These all mean roughly the same thing, but the emphasis changes:

• towar first emphasizes the item
• za darmo first emphasizes that it is free

The original sentence is neutral and natural.

Because it uses odesłać, which is a perfective infinitive, it presents the action as a complete whole: to send back / to return.

However, in a sentence with możesz, the overall meaning is usually about possibility or permission, not about tense in the English sense.

So it means:

• You can return it
• You are able/allowed to send it back

It does not mean the person has already returned it.

A rough contrast:

• odsyłać = to be sending back / to send back repeatedly or habitually
• odesłać = to send back once, as a complete action

In return-policy language, odesłać is very natural because a return is usually seen as one complete action.

In theory, odesłać literally means send away/back, so without context it could sound broader than English return.

But in a shopping or customer-service context, native speakers will normally understand it as:

• send the item back
• return the goods

So in real use, especially on a website or store page, the intended meaning is almost certainly return the item for free.

Because Polish has no articles.

English distinguishes:

• a product
• the product

Polish usually just says:

• towar

The exact meaning depends on context.

So towar can correspond to:

• a product
• the product
• an item
• the item
• goods

That is completely normal in Polish.
