Пожалуйста, выбрось салфетку в урну у входа.

Выбрось is the imperative singular of выбросить, which is a perfective verb. In this sentence, it means throw it away or dispose of it as one complete action.

Russian often uses the perfective imperative when you want someone to do a single, completed action:

• выбрось = throw away / toss out
• сделай = do it
• закрой = close it

If you used an imperfective form such as выбрасывай, it would sound more like a repeated action, a process, or a general instruction depending on context.

Because салфетку is in the accusative case, which is used here for the direct object of the verb выбрось.

The base form is:

• салфетка = napkin / tissue

For a feminine noun ending in -а, the accusative singular usually changes -а to -у:

• салфетка → салфетку

So:

• выбрось салфетку = throw away the napkin/tissue

Because в can mean either into or in, depending on the case.

Here, the sentence describes movement toward a destination: putting something into the bin. That requires the accusative case:

• в урну = into the bin

Compare:

• в урне = in the bin

So:

• выбрось салфетку в урну = throw the tissue into the bin
• салфетка в урне = the tissue is in the bin

In everyday Russian, урна usually means a public trash bin, waste bin, or receptacle for litter, especially in places like entrances, streets, offices, or stations.

Depending on context, English might translate it as:

• bin
• trash can
• wastebasket
• litter bin

Although урна can also mean urn in some contexts, in this sentence it clearly means a trash bin.

У входа literally means by the entrance or near the entrance.

It uses the preposition у, which often means by, near, or at, and it requires the genitive case:

• вход = entrance
• у входа = by the entrance

This phrase tells you which bin is meant:

• урну у входа = the bin by the entrance

Because the preposition у requires the genitive case.

The noun is:

• вход = entrance

Its genitive singular form is:

• входа

So:

• у входа = by the entrance

This is a very common pattern:

• у двери = by the door
• у окна = by the window
• у дома = by the house

Russian does not have articles like a, an, or the.

So whether something is understood as a tissue, the tissue, a bin, or the bin depends on context.

In this sentence:

• салфетку could mean the tissue/napkin or a tissue/napkin
• урну у входа could mean the bin by the entrance

English has to choose an article, but Russian usually leaves that unstated.

Yes, пожалуйста makes the request polite, even though выбрось is the informal singular imperative.

So this sentence is polite but still informal, appropriate when speaking to:

• one friend
• one child
• one family member
• someone you address as ты

If you wanted to be polite to someone you address as вы, you would usually say:

• Пожалуйста, выбросьте салфетку в урну у входа.

That is the formal/plural imperative.

Yes. Russian word order is fairly flexible, and the basic meaning would stay the same, though emphasis may change.

For example:

• Пожалуйста, выбрось салфетку в урну у входа.
• Салфетку, пожалуйста, выбрось в урну у входа.
• Выбрось, пожалуйста, салфетку в урну у входа.

The original version sounds natural and neutral. Moving words around can highlight a specific part, but learners should usually stick with the original order until they get comfortable with Russian emphasis patterns.

It can mean either, depending on context.

Салфетка is a broad word that can refer to:

• a paper napkin
• a table napkin
• sometimes a tissue or wipe, depending on the situation

In a sentence about throwing it into a bin, English might translate it as either napkin or tissue, depending on what the object is.

If you want to be more specific:

• бумажная салфетка = paper napkin
• носовой платок = handkerchief
• бумажный носовой платок or салфетка may sometimes be used for tissue, depending on region and context

It is a little tricky because of the consonant cluster at the end.

A helpful pronunciation guide is:

• выбрось ≈ VY-bros’

The stress is on the first syllable:

• ВЫбрось

The final -сь is soft, so the word ends with a softened s sound. You do not pronounce it as a separate full syllable.

The whole sentence with stress marks would be:

• Пожа́луйста, ВЫбрось салфе́тку в у́рну у вхо́да.

Yes, in many contexts you could say в мусорку, especially in everyday speech.

Compare:

• урна = a bin, often a public or visible waste bin
• мусорка = informal; trash can / garbage bin
• мусорное ведро = trash bin, garbage pail, often in a home

So:

• выбрось салфетку в урну sounds natural if there is a bin near the entrance in a public or shared space
• выбрось салфетку в мусорку sounds more colloquial

In this sentence, урну is a good, standard choice.
