Гарантійний строк — два роки.

In Ukrainian, the verb to be is usually omitted in the present tense.

So:

• Гарантійний строк — два роки. literally = The warranty period — two years but naturally means The warranty period is two years.

This is very normal in Ukrainian. If you want past or future, then forms of бути would appear:

• Гарантійний строк був два роки. = The warranty period was two years.
• Гарантійний строк буде два роки. = The warranty period will be two years.

The dash marks the link between the subject and the predicate, especially in sentences where is is omitted.

So here:

• Гарантійний строк = the warranty period
• два роки = two years

The dash helps show that the second part identifies or states the length of the first part.

In English, we usually use is:

• The warranty period is two years.

In Ukrainian, the dash is common in this kind of sentence, especially in writing.

It means warranty period or guarantee period.

Breakdown:

• гарантійний = warranty / guarantee-related
• строк = term, period, length of time

So гарантійний строк is the period during which a product is covered by a warranty.

A close synonym you may also see is:

• гарантійний термін

Both can often mean warranty period, though строк often feels a bit more like a defined official period of time.

Because after the number 2, Ukrainian uses the noun in the form seen in:

• два роки = two years

This is the normal pattern for 2, 3, 4:

• два роки = two years
• три роки = three years
• чотири роки = four years

But after 5 and higher, the noun changes:

• п’ять років = five years
• десять років = ten years

So the sentence uses the correct form for 2.

Because рік (year) is a masculine noun.

In Ukrainian:

• два is used with masculine and neuter nouns
• дві is used with feminine nouns

Examples:

• два роки = two years
• два вікна = two windows
• дві книги = two books

Since рік is masculine, the correct form is два.

Рік is the basic singular dictionary form: year.

But after numbers, Ukrainian often changes the noun form. After 2, 3, 4, рік becomes роки:

• один рік = one year
• два роки = two years
• три роки = three years
• чотири роки = four years

Then after 5+, it becomes років:

• п’ять років

So роки is just the correct counted form after два.

This word order is the most neutral and natural:

• Гарантійний строк — два роки.

It starts with the thing being talked about, then gives the information about it.

You may sometimes see variations for emphasis, but this is the standard way to state it in a product description, contract, or technical text.

So for a learner, this is the safest pattern to copy:

• [thing] — [value/description]

Examples:

• Ціна — 100 гривень. = The price is 100 hryvnias.
• Термін доставки — три дні. = The delivery time is three days.

They are similar, and in many real-life contexts both can be translated as term, period, or duration.

For warranty language, both are common:

• гарантійний строк
• гарантійний термін

However, строк often sounds a bit more formal or legal/official when talking about a defined period set by rules, contracts, or law.

So in this sentence, строк is perfectly natural and appropriate.

A rough pronunciation guide:

• Гарантійний ≈ ha-ran-TEEY-nyy
• строк ≈ strok
• два ≈ dva
• роки ≈ RO-ky

So the full sentence is roughly:

ha-ran-TEEY-nyy strok — dva RO-ky

A couple of useful notes:

• Ukrainian г sounds like a softer h sound, not a hard English g
• и is not exactly English ee or ih; it is a separate Ukrainian vowel
• й gives a y-like glide sound

Yes, very natural.

This kind of short sentence is exactly the style you would expect in:

• product specifications
• manuals
• warranty documents
• labels
• online store descriptions

Ukrainian often uses compact, verb-less statements in formal and technical writing, so Гарантійний строк — два роки. sounds normal and idiomatic.

Yes. This is a very useful model.

You can replace the noun and the time period:

• Термін дії — один рік. = The validity period is one year.
• Термін доставки — три дні. = The delivery time is three days.
• Строк оренди — шість місяців. = The rental period is six months.

So a good pattern to remember is:

• [noun phrase] — [number] + [time word]

That pattern is extremely common in Ukrainian.
