Если у Вас есть ножницы и клей, можно быстро вырезать звезду и приклеить её к картону.

Russian usually expresses possession with the pattern у + genitive + есть.

• у Вас = by/at you → idiomatically you have
• есть = there is / there exists

So Если у Вас есть ножницы и клей... literally feels like:

• If at your place there are scissors and glue...

This is the normal way to say have in Russian.

A few related points:

• Вас is the genitive form after у
• the dictionary form is Вы = you (formal or plural)
• in everyday speech, есть is often omitted in the present tense, but with possession it is very common when you want to clearly state that something is available

Вас is capitalized here because it refers to a single person in the polite/formal you sense.

Russian distinguishes:

• ты = informal singular you
• Вы = formal singular you or plural you

In polite writing, forms of Вы are often capitalized:

• Вы
• Вас
• Вам
• Ваш

So у Вас есть is a respectful way of saying if you have.

In many modern texts, especially less formal ones, you may also see lowercase вас even when speaking politely. Capitalization is a style choice showing extra politeness.

Yes. Ножницы is one of those Russian nouns that normally exist only in the plural, just like English scissors.

So Russian treats it grammatically as plural:

• эти ножницы = these scissors
• новые ножницы = new scissors
• у меня есть ножницы = I have scissors

There is no normal singular form meaning one scissor in everyday use.

This is why the sentence says ножницы, not some singular noun.

Because клей means glue, which is normally treated as a mass noun, like water or sand in English.

So in the sentence:

• ножницы = plural-only noun
• клей = singular mass noun

That is completely natural in Russian:

• есть ножницы и клей = there are scissors and glue

Russian is not trying to make the grammar of the two nouns match; it just uses the normal form of each noun.

Можно is an impersonal word meaning something like:

• it is possible
• one can
• you can

So:

• можно быстро вырезать звезду... = it is possible to quickly cut out a star... = more naturally, you can quickly cut out a star...

Russian often uses impersonal constructions where English prefers a subject such as you, we, or one.

This makes the sentence sound general:

• If you have scissors and glue, one can / you can quickly cut out a star...

It is not talking about a specific named person; it means this is generally doable.

Because they depend on можно.

After можно, Russian usually uses the infinitive:

• можно сделать = you can do
• можно читать = you can read
• можно приклеить = you can glue

So in this sentence:

• можно быстро вырезать звезду и приклеить её к картону

literally means:

• it is possible to quickly cut out a star and glue it to cardboard

This is the standard structure: можно + infinitive.

They are perfective because the sentence talks about completed actions with a result:

• вырезать = to cut out (successfully, as a completed action)
• приклеить = to glue on / attach with glue (completed)

That fits the meaning well: you cut out a star and then glue it onto cardboard.

If imperfective verbs were used instead, the focus would be more on the process or repeated activity:

• вырезать / приклеить = complete the task
• вырезать is actually perfective; its imperfective partner is often вырезать? No—more precisely, вырезать is perfective, and the imperfective is usually вырезать only in some contexts? The usual pair is вырезать (pf) and вырезать / вырезывать historically, but learners mainly meet вырезать as perfective.
• приклеить (pf) vs приклеивать (impf)

For a learner, the practical point is: this sentence is about getting a finished result, so perfective verbs make sense.

Резать means to cut in a general sense.

Вырезать means to cut out, that is, to produce a shape by cutting.

So:

• резать бумагу = to cut paper
• вырезать звезду из бумаги = to cut a star out of paper

In this sentence, the goal is not just cutting in general, but creating a star shape, so вырезать is the right verb.

Because звезду is the accusative case, used for the direct object of вырезать.

Dictionary form:

• звезда = star

Direct object form:

• вырезать звезду = to cut out a star

Since звезда is a feminine noun ending in -а, its accusative singular usually changes to -у:

• звезда → звезду
• книга → книгу
• машина → машину

So звезду is exactly what we expect after the verb.

Её means it/her, and here it refers back to звезду.

So:

• вырезать звезду и приклеить её к картону = cut out a star and glue it to the cardboard

Russian sometimes omits pronouns when the meaning is obvious, but here её helps make the object of приклеить explicit.

Without её, the sentence might still be understood in context, but её makes the connection clearer: the thing you glue is the star you just cut out.

Because звезда is feminine, the pronoun is feminine too:

• её = her / it for feminine nouns

Картону is dative case, because the preposition к normally takes the dative.

• к = to, toward
• картон = cardboard
• к картону = to the cardboard / onto the cardboard

So:

• приклеить её к картону = to glue it to cardboard

This is a very common pattern:

• к дому = to the house
• к двери = to the door
• к окну = to the window

The dative ending here is:

• картон → картону

Here картон means cardboard, not a carton in the English packaging sense.

So к картону means the star is being glued onto a piece of cardboard or cardboard backing.

This can be confusing for English speakers because the words look similar, but in this sentence the meaning is clearly the craft material cardboard.

In this sentence, быстро most naturally applies to the whole action sequence, especially starting with вырезать and then continuing to приклеить.

So the overall sense is:

• you can quickly cut out a star and glue it to cardboard

In practice, learners can understand it as modifying the whole predicate after можно. Russian often places an adverb once, even when it semantically covers more than one connected action.

Russian has no articles like English a/an and the.

So:

• звезду can mean a star or the star
• к картону can mean to cardboard or to the cardboard

The exact meaning comes from context.

In this sentence, English would usually say:

• cut out a star and glue it to cardboard

Russian does not need separate article words to express that.

Yes, if you were speaking informally to one person.

Compare:

• Если у Вас есть ножницы и клей... = formal/polite
• Если у тебя есть ножницы и клей... = informal singular

So the grammar pattern stays the same; only the level of formality changes.

That means:

• у Вас = formal you have
• у тебя = informal singular you have
• у вас can also mean you all have

The word order is natural, but Russian allows some flexibility.

This version:

• Если у Вас есть ножницы и клей, можно быстро вырезать звезду и приклеить её к картону.

sounds neutral and clear.

You could change parts of the order for emphasis, for example:

• Если у Вас есть ножницы и клей, звезду можно быстро вырезать и приклеить её к картону.

That shifts the focus slightly toward звезду.

Russian word order is more flexible than English because case endings show the grammatical roles, but not every rearrangement sounds equally natural. The original sentence is a good standard model.

Yes, but that would change the meaning.

• вырезать звезду из картона = cut out a star from cardboard
• приклеить её к картону = glue it to cardboard

In the given sentence, the star is cut out and then attached to cardboard, so the focus is on where it is glued.

If the material being cut were cardboard, then из картона would be appropriate. But к картону means attachment to a surface, not material source.
