Якщо оренда не надто висока, ми хочемо орендувати квартиру вже цього тижня.

They are related, but they are different parts of speech:

• оренда = rent / rental as a noun
• орендувати = to rent as a verb

So in this sentence:

• Якщо оренда не надто висока = If the rent is not too high
• ми хочемо орендувати квартиру = we want to rent an apartment

English also does this with different word types:

• the rent
• to rent

Ukrainian just happens to use clearly related forms.

Because висока agrees with оренда, which is a feminine singular noun.

In Ukrainian, adjectives must agree with the noun in:

• gender
• number
• case

Here:

• оренда is feminine singular nominative
• so the adjective must also be feminine singular nominative: висока

Compare:

• високий будинок = a tall building masculine
• висока ціна = a high price feminine
• високе дерево = a tall tree neuter

So оренда не надто висока literally works like the rent is not too high.

In this sentence, не надто висока most naturally means not too high.

• надто = too, excessively, overly
• не надто = not too, not excessively

So:

• оренда не надто висока = the rent is not too high

Depending on context, не надто can sometimes feel close to not very, but here not too high is the best reading because rent is being evaluated as acceptable or unacceptable.

Because квартиру is the accusative singular form, and it is the direct object of орендувати.

• dictionary form: квартира
• accusative singular: квартиру

We use the accusative because the action is being done to that noun:

• орендувати квартиру = to rent an apartment

This is very common in Ukrainian:

• читати книжку = to read a book
• бачити машину = to see a car
• купити квартиру = to buy an apartment

For many feminine nouns ending in -а, the accusative singular changes to -у or -ю.

Because after хотіти = to want, Ukrainian normally uses the infinitive.

So:

• хочемо орендувати = we want to rent

This is similar to English:

• we want to rent not
• we want we rent

A few examples:

• Я хочу спати. = I want to sleep.
• Вони хочуть купити будинок. = They want to buy a house.
• Ми хочемо орендувати квартиру. = We want to rent an apartment.

So орендувати stays in the infinitive because it depends on хочемо.

Хочемо is the 1st person plural present tense form of хотіти = to want.

So:

• я хочу = I want
• ти хочеш = you want
• він/вона хоче = he/she wants
• ми хочемо = we want
• ви хочете = you plural/formal want
• вони хочуть = they want

That is why ми хочемо means we want.

Yes, вже often means already, but in context it can sound more natural in English as:

• already
• as early as
• sometimes just added emphasis

Here:

• вже цього тижня suggests already this week or as early as this week

It gives a sense that the action should happen soon, sooner than one might expect.

So the sentence has a feeling like:

• If the rent isn’t too high, we want to rent the apartment already this week.
• more natural English: If the rent isn’t too high, we want to rent the apartment this week already / as early as this week.

Because Ukrainian often uses the genitive case to express time within which something happens.

So:

• цього тижня = this week literally something like of this week

This is a very common time expression pattern:

• цього року = this year
• цього місяця = this month
• цього тижня = this week

Here:

• цей тиждень is nominative
• цього тижня is genitive

When talking about when something happens, Ukrainian often prefers the genitive form.

It is the genitive singular.

Breakdown:

• цей = this
• genitive masculine/neuter singular form: цього
• тиждень = week
• genitive singular: тижня

So:

• цього тижня = of this week, used idiomatically to mean this week

This is one of those very common Ukrainian patterns that is best learned as a chunk.

Yes, very often it could be.

Ukrainian is a pro-drop language, which means the subject pronoun is often unnecessary because the verb ending already shows the person and number.

• хочемо already tells you we want

So both are possible:

• Ми хочемо орендувати квартиру...
• Хочемо орендувати квартиру...

Including ми can add:

• emphasis
• contrast
• clarity

For example, ми might be kept if you want to stress we rather than someone else.

Yes. Якщо is the standard word for if when introducing a condition.

So:

• Якщо оренда не надто висока... = If the rent is not too high...

It introduces the condition under which the second part is true.

You will also sometimes see коли in contexts where English uses if, especially when the speaker expects the condition to be fulfilled, but якщо is the basic and safest translation for if.

Yes. In Ukrainian, a subordinate clause introduced by якщо is normally separated by a comma.

So the structure is:

• Якщо оренда не надто висока,
  conditional clause
• ми хочемо орендувати квартиру вже цього тижня.
  main clause

This comma is standard Ukrainian punctuation.

The word order is fairly natural, but Ukrainian word order is more flexible than English.

The original sentence:

• Якщо оренда не надто висока, ми хочемо орендувати квартиру вже цього тижня.

Possible variations could include:

• Якщо оренда не надто висока, вже цього тижня ми хочемо орендувати квартиру.
• Ми хочемо вже цього тижня орендувати квартиру, якщо оренда не надто висока.

These are all understandable, but the original sounds neutral and natural.

Word order changes usually affect:

• emphasis
• rhythm
• what information is highlighted

It can mean both, depending on context.

Оренда can refer to:

• rent as the price you pay
• rental / renting more generally

In this sentence, because of не надто висока = not too high, it clearly means the rent amount / rental price.

If you wanted to be even more explicit, Ukrainian could also use things like:

• вартість оренди = the cost of the rent/rental
• орендна плата = rental payment / rent

But оренда here is completely natural.

Yes. Квартира is the normal Ukrainian word for an apartment or flat.

Depending on the variety of English:

• American English: apartment
• British English: flat

So:

• орендувати квартиру = to rent an apartment / flat

It usually refers to a self-contained living space in a building, not a whole house.

Yes, this is perfectly normal.

Орендувати квартиру is a standard way to say to rent an apartment.

Depending on context, you might also hear:

• зняти квартиру = literally to take/rent an apartment

In everyday speech, зняти квартиру is very common when talking about renting a place to live.

So:

• хочемо орендувати квартиру = correct and standard
• хочемо зняти квартиру = also very common, especially colloquially

Both are useful to know.
