Не кидай сумку на підлогу.

Кидай is the informal singular imperative of кидати.

So it is the form you use when telling one person: throw / drop.

• кидати = to throw, to toss, to drop
• кидай = throw! / drop!
• не кидай = don’t throw! / don’t drop!

In this sentence, it is a command to one person.

This is how Ukrainian makes a negative command:

• не = not / don’t
• кидай = throw / drop

So:

• кидай сумку = throw the bag
• не кидай сумку = don’t throw the bag

This is very similar to English Don’t + verb.

This is a question about aspect.

• кидати is imperfective
• кинути is perfective

Their imperatives are:

• кидай = imperfective imperative
• кинь = perfective imperative

In negative commands, Ukrainian often prefers the imperfective for a general prohibition:

• Не кидай сумку на підлогу. = Don’t throw/drop the bag on the floor.

That sounds like a normal rule or warning.

A perfective form like не кинь is possible in some contexts, but it gives a different nuance and is less neutral here. It can sound more like don’t let yourself throw it / don’t go and throw it once. For a basic Don’t do that, не кидай is the natural choice.

Because сумку is the accusative case, and it is the direct object of the verb.

The basic dictionary form is:

• сумка = bag

But after a transitive verb like кидати (to throw), the thing being thrown goes into the accusative:

• сумка → сумку

So:

• Не кидай сумку = Don’t throw the bag

This is very normal in Ukrainian grammar.

Because this sentence expresses movement toward a place.

With на, Ukrainian uses:

• accusative for motion onto/to
• locative for location on

So:

• на підлогу = onto the floor / to the floor
• на підлозі = on the floor

Compare:

• Не кидай сумку на підлогу. = Don’t throw the bag onto the floor.
• Сумка лежить на підлозі. = The bag is lying on the floor.

So here підлогу is accusative because the bag is being directed onto the floor.

More literally, it means onto the floor.

In natural English, we often say:

• Don’t throw the bag on the floor
• Don’t drop the bag on the floor

But grammatically, Ukrainian is showing direction toward the floor, which is why it uses на підлогу.

So if you want the most literal sense, think:

• на підлогу = onto the floor

Yes. Кидай is the command form for one person in an informal situation.

You would use it with:

• a friend
• a child
• someone you address with ти

If you want to be polite or speak to more than one person, use:

• Не кидайте сумку на підлогу.

So:

• не кидай = don’t throw/drop (singular, informal)
• не кидайте = don’t throw/drop (plural or polite)

It is understood, not stated.

Ukrainian often leaves out subject pronouns when the verb form already makes the meaning clear. The imperative кидай already tells you that the speaker is talking to you.

So Ukrainian normally says:

• Не кидай сумку на підлогу.

not

• Ти не кидай сумку на підлогу.

Adding ти is possible, but it gives extra emphasis, contrast, or emotion.

Yes, Ukrainian word order is flexible, but the original order is the most neutral and natural.

Neutral:

• Не кидай сумку на підлогу.

You might also hear:

• Сумку не кидай на підлогу. — extra emphasis on the bag
• На підлогу не кидай сумку. — extra emphasis on the floor

So the words can move, but the sentence as given is the straightforward default version.

It can cover both ideas, depending on context.

In this sentence, English could translate it as:

• Don’t throw the bag on the floor
• Don’t drop the bag on the floor

The exact shade depends on the situation:

• if someone is tossing it carelessly, throw
• if someone is letting it fall, drop

But кидати usually suggests some kind of careless or forceful movement, not gently placing something down.

If you wanted Don’t put the bag on the floor, a more natural Ukrainian verb would often be класти:

• Не клади сумку на підлогу.

The stress is:

• Не кида́й су́мку на підло́гу.

A rough pronunciation guide:

• не = ne
• кида́й = ky-DAI
• су́мку = SOOM-koo
• на = na
• підло́гу = pid-LO-hu

A few helpful pronunciation notes:

• и in кидай is not exactly English ee; it is a shorter, more central vowel.
• Ukrainian г in підлогу is pronounced like a soft voiced h, not like English hard g.
• The stressed syllables are important for sounding natural: кида́й, су́мку, підло́гу.

Yes. A form like не кидай can work both as:

• a command in the moment: Don’t throw it on the floor!
• a general instruction or rule: Don’t throw your bag on the floor.

Because the verb is imperfective, it works especially well for a general prohibition or repeated behavior. So it can sound like either:

• Stop, don’t do that now or
• That’s not something you should do

depending on context.
