Мы купили путёвку на морской курорт, потому что хотели несколько дней отдохнуть у воды.

Путёвка is a very common Russian word for a travel package / holiday package / resort voucher.

In this sentence, Мы купили путёвку на морской курорт means something like:

• We bought a vacation package to a seaside resort
• or We bought a trip to a seaside resort

It is not just a simple ticket. A путёвка often suggests an arranged stay, especially to a resort, sanatorium, or holiday destination.

The form путёвку is accusative singular, because it is the direct object of купили.

Купили is the past tense plural form of купить.

It tells us:

• купить = to buy (perfective)
• купили = bought
• plural because the subject is мы = we

So:

• я купил / купила = I bought
• ты купил / купила = you bought
• мы купили = we bought

Because купить is perfective, купили presents the action as completed: they actually bought the package.

Because after на and a verb of motion or directed action, Russian often uses the accusative to show destination.

Here, the package is to a resort:

• на курорт = to a resort
• морской курорт = seaside resort
• на морской курорт = to a seaside resort

This is similar to:

• ехать на курорт = to go to a resort
• поехать на юг = to go south

The adjective and noun both match in the accusative singular masculine:

• морской → unchanged in masculine accusative (for an inanimate noun)
• курорт → unchanged in masculine accusative (also because it is inanimate)

So the phrase looks the same as the nominative, but its role is accusative.

Russian usually uses an adjective here: морской = sea / seaside / marine.

So:

• морской курорт = seaside resort

This is the natural Russian way to describe a resort by the sea.

Курорт моря would sound unnatural in this context. Russian prefers the adjective rather than a noun-to-noun structure like English often allows.

A very common alternative is:

• курорт на море = a resort at the sea / a seaside resort

Both are understandable, but морской курорт is a compact standard phrase.

Because потому что introduces a subordinate clause, like because in English.

The sentence has two parts:

1. Мы купили путёвку на морской курорт
2. потому что хотели несколько дней отдохнуть у воды

Russian normally puts a comma before потому что:

• ..., потому что ...

So the comma is required by standard punctuation.

Yes. Потому что is the standard, very common way to say because.

So:

• Мы купили путёвку..., потому что хотели...
• We bought a package..., because we wanted...

There are other ways to express cause in Russian, but потому что is the most straightforward and neutral one for learners.

Because in Russian, after хотеть (to want), you normally use an infinitive to express wanting to do something.

So:

• хотели = wanted
• отдохнуть = to rest / to have a rest / to relax

Together:

• хотели отдохнуть = wanted to relax / wanted to get some rest

This works just like English:

• They wanted to rest
• Они хотели отдохнуть

And хотели is past plural, matching мы.

This is an aspect question.

• отдыхать = imperfective = to be resting / to rest in general
• отдохнуть = perfective = to get some rest / to have a rest / to rest and reach the result

In this sentence, отдохнуть is used because the speakers mean they wanted to spend some days resting and come away rested. It is viewed as a complete, bounded action.

So:

• хотели отдохнуть несколько дней = they wanted to rest for several days

If you used отдыхать, it would focus more on the process or general activity, and it would sound less natural here.

Несколько is a quantity word meaning several. After it, the noun usually goes in the genitive plural.

So:

• день = day
• дни = days
• дней = genitive plural of день

That is why Russian says:

• несколько дней = several days

This is a very common pattern:

• несколько минут = several minutes
• несколько человек = several people
• несколько книг = several books

Even though the whole phrase means for several days, the noun itself is in genitive plural because of несколько.

Russian often expresses duration without a preposition.

So:

• несколько дней отдохнуть literally looks like to rest several days
• but it means to rest for several days

This is normal in Russian. Duration of time is often expressed directly by a time phrase:

• ждать час = to wait for an hour
• работать весь день = to work all day
• прожить там год = to live there for a year

So English needs for, but Russian often does not.

У воды means by the water, near the water, or next to the water.

Breaking it down:

• у = by / near
• воды = genitive singular of вода (water)

So the phrase suggests being close to water, probably the sea, shore, or waterfront.

It does not mean in the water or on the water.

Compare:

• у воды = by the water
• в воде = in the water
• на воде = on the water

Because the preposition у requires the genitive case.

So:

• nominative: вода
• genitive: воды

That gives:

• у воды = by the water

This is a basic preposition + case pattern you will see often:

• у дома = by the house
• у окна = by the window
• у моря = by the sea

Yes, definitely.

• у моря = by the sea
• у воды = by the water

In this sentence, у воды is a little broader and more atmospheric. It suggests being near water in general, not just naming the sea directly.

Since the first part already mentions a морской курорт (seaside resort), using у воды avoids repeating море.

So the choice sounds natural and stylistic, not strange.

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

The given sentence is neutral and smooth:

• Мы купили путёвку на морской курорт, потому что хотели несколько дней отдохнуть у воды.

You could rearrange parts for emphasis, for example:

• Потому что хотели несколько дней отдохнуть у воды, мы купили путёвку на морской курорт.

That is grammatically possible, but less neutral in ordinary conversation.

So the original order is the most natural default order.

Yes, it could be omitted, because Russian past-tense verbs often already show number, and context can identify the subject.

So both are possible:

• Мы купили путёвку...
• Купили путёвку...

However, including мы is completely normal. It can make the sentence clearer or slightly more explicit.

Russian often omits pronouns when they are obvious, but it does not have to.

They are very close in meaning.

• морской курорт = seaside resort
• курорт на море = resort at the sea / seaside resort

The first is a compact adjective+noun phrase. The second is a noun phrase with a prepositional description.

Both are natural, but морской курорт sounds a bit more like a set phrase, while курорт на море feels a little more descriptive.

The main stresses are:

• мы купи́ли путёвку на морско́й куро́рт, потому́ что хоте́ли не́сколько дней отдохну́ть у воды́

A few especially useful ones to remember:

• путёвка
• морско́й
• куро́рт
• потому́
• хоте́ли
• отдохну́ть
• воды́

Stress is important in Russian, because it is not always predictable.
