Вона бере з рюкзака маленьку пляшку і йде до спортзалу.

Бере is the 3rd-person singular present form of the verb брати.

So:

• брати = to take
• вона бере = she takes / she is taking

A useful thing to notice is that the stem changes:

• брати
• беру
• береш
• бере

That change is normal for this verb.

It can mean either one.

In Ukrainian, the present tense often covers both:

• she takes
• she is taking

The exact English translation depends on context. In this sentence, English might naturally use is taking if we are describing what she is doing right now, but takes is also possible in some contexts.

Because з here means from / out of, and after this kind of meaning Ukrainian uses the genitive case.

The noun рюкзак changes like this:

• рюкзак = backpack
• з рюкзака = from the backpack / out of the backpack

So the ending -а shows the genitive singular.

Also, з, із, and зі are often just pronunciation variants of the same preposition. Which one is used can depend on what sounds smoother.

Because this is the direct object of the verb бере, so it must be in the accusative case.

Base form:

• маленька пляшка = a small bottle

After бере:

• маленьку пляшку = a small bottle

Both words change because the adjective must agree with the noun:

• маленька → маленьку
• пляшка → пляшку

This is the normal accusative singular pattern for many feminine nouns ending in -а and their adjectives.

Yes, very often it can.

Ukrainian often drops subject pronouns when the meaning is clear from context. So a sentence like this could also appear without вона.

However, keeping вона is natural too. It can help:

• make the subject clearer
• emphasize that it is she
• contrast her with someone else

In this sentence, вона is especially helpful because the verb forms бере and йде show 3rd person singular, but they do not show gender by themselves.

Yes, іде is also possible in Ukrainian, but йде is very common.

This verb comes from йти / іти, meaning to go / to walk.

Here:

• йде = goes / is going

In this sentence, і йде sounds very natural, and speakers often prefer йде after і so they do not get the awkward sequence і іде.

So:

• і йде = very natural
• і іде = possible in some usage, but usually avoided

До спортзалу means to the gym in the sense of moving toward that destination.

The preposition до takes the genitive case, so:

• спортзал = gym
• до спортзалу = to the gym

A sentence with в спортзал is also possible, but the nuance can be a little different:

• до спортзалу = to/toward the gym
• в спортзал = into the gym

In real life, both can sometimes be translated simply as to the gym, but в focuses more on entering the place.

Because до requires the genitive case.

So the noun changes:

• спортзал = gym
• до спортзалу = to the gym

This is a standard masculine singular genitive form here. So the ending is not random; it is caused by the preposition до.

Because Ukrainian does not have articles.

So where English says:

• a small bottle
• the small bottle
• the gym

Ukrainian simply uses the noun, and the listener understands from context whether it is definite or indefinite.

That means маленьку пляшку could mean:

• a small bottle
• the small bottle

depending on the situation.

No, Ukrainian word order is fairly flexible.

This sentence uses a very normal, neutral order:

• Вона бере з рюкзака маленьку пляшку і йде до спортзалу.

But you can move parts around for emphasis, for example:

• З рюкзака вона бере маленьку пляшку і йде до спортзалу.
• Маленьку пляшку вона бере з рюкзака і йде до спортзалу.

The meaning stays understandable because the case endings show what each word is doing:

• рюкзака = from the backpack
• пляшку = direct object
• спортзалу = destination after до

So word order affects emphasis more than basic grammar.
