Повернемо товар, якщо тільки пропозиція продавця не включає гарантійний ремонт.

In this sentence, якщо тільки ... не works as an idiomatic way to say unless.

So:

• якщо = if
• тільки = only
• не = not

But together, якщо тільки ... не means something like unless or except if.

So:

• Повернемо товар, якщо тільки пропозиція продавця не включає гарантійний ремонт. = We will return the item unless the seller’s offer includes warranty repair.

The не is normal and expected in this Ukrainian structure. Even though English uses unless without a separate not, Ukrainian often keeps this negative wording.

Повернемо is the 1st person plural future form of the perfective verb повернути.

That is an important Ukrainian pattern:

• imperfective verbs form the future with a helper or special future forms
• perfective verbs use their present-looking endings to express future

So:

• повертати = to be returning / to return repeatedly or as a process
• повернути = to return once, to complete the return

From повернути, we get:

• я поверну
• ми повернемо

Even though the form looks similar to a present-tense pattern, perfective verbs do not have a true present meaning in this form. Повернемо means we will return.

Depending on context, it can also sound a bit like let’s return it, but in this sentence the most natural reading is future: we will return the item.

Here, товар is the direct object of повернемо, so it is in the accusative case.

For masculine inanimate singular nouns, the accusative usually looks the same as the nominative.

So:

• nominative: товар
• accusative: товар

That is why the form does not change.

Compare:

• Ми повернемо товар. = We will return the item.
• Товар дорогий. = The item is expensive.

Same form, different function.

Продавця is in the genitive singular.

The phrase пропозиція продавця literally means the offer of the seller, which in natural English is the seller’s offer.

This is a very common Ukrainian pattern:

• книга студента = the student’s book
• будинок брата = the brother’s house
• пропозиція продавця = the seller’s offer

So:

• пропозиція = offer
• продавець = seller
• продавця = of the seller / seller’s

Because Ukrainian often uses the present tense in clauses that describe a condition, especially when the condition is viewed as a current fact or as the relevant content of something.

Here, пропозиція продавця не включає гарантійний ремонт means:

• the seller’s offer does not include warranty repair

That is treated as a statement about what the offer contains.

So the sentence means something like:

• We will return the item unless the seller’s offer includes warranty repair.

The main action is future (Повернемо), but the condition is stated as a present fact about the offer (включає).

This is very natural in both Ukrainian and English:

• We’ll buy it if the price includes delivery.
• We’ll return it unless the offer includes warranty repair.

Гарантійний ремонт is in the accusative singular because it is the direct object of включає (includes).

Again, because ремонт is a masculine inanimate noun, its accusative singular looks the same as the nominative singular.

So:

• nominative: гарантійний ремонт
• accusative: гарантійний ремонт

That is why both words stay in the same visible form.

Not exactly.

• гарантія = warranty / guarantee
• ремонт = repair
• гарантійний ремонт = warranty repair, repair under warranty

So this phrase does not mean just a warranty in general. It specifically means that the item would be repaired under the warranty terms.

That distinction matters:

• включає гарантію = includes a warranty
• включає гарантійний ремонт = includes warranty repair

The second is more specific.

Yes. Ukrainian word order is fairly flexible, and this sentence could be rearranged without changing the basic meaning.

For example:

• Якщо тільки пропозиція продавця не включає гарантійний ремонт, повернемо товар.

This still means the same thing.

The version you were given starts with Повернемо товар, which puts a little more focus on the main action: we will return the item.

So the choice of word order is often about emphasis, rhythm, or style rather than a big difference in meaning.

Because якщо тільки пропозиція продавця не включає гарантійний ремонт is a subordinate clause.

Ukrainian normally uses a comma to separate the main clause from a subordinate clause introduced by words like:

• якщо = if
• коли = when
• що = that
• тому що = because

So:

• Повернемо товар, якщо тільки ...

The comma is standard punctuation here.

Not exactly. They overlap, but they are used differently.

• товар = merchandise, goods, item for sale
• річ = thing, item, object
• продукт = product

In a shopping, retail, or return-policy context, товар is very natural because it refers to something being sold or purchased.

So повернути товар is a common expression meaning to return an item / return goods.

If you said повернути річ, that would mean returning a thing, but it sounds more general and less specifically commercial.

It can sometimes do both, depending on context.

The form Повернемо is grammatically the 1st person plural future of a perfective verb, so its basic meaning is:

• we will return

But in real usage, first-person plural future forms can sometimes sound like a suggestion, similar to:

• let’s return it

In this sentence, though, the presence of the condition clause makes the plain future reading much more natural:

• We will return the item unless ...

So while the form can occasionally be used in a suggestion-like way, here it is best understood as a future action.

Because Ukrainian has no articles.

English uses:

• a seller
• the seller
• an offer
• the item

Ukrainian usually leaves this unspecified unless context makes it clear or another word adds that meaning.

So:

• товар can mean an item, the item, or goods
• пропозиція продавця can mean the seller’s offer or a seller’s offer, depending on context

The exact English article comes from the situation, not from a separate Ukrainian word.
