Велосипедист може правильно гальмувати.

Може is the 3rd person singular present-tense form of могти (to be able to / can).

So:

• я можу = I can
• ти можеш = you can
• він / вона / воно може = he / she / it can

In this sentence, the subject is велосипедист (cyclist), which is singular, so може is the correct form.

After могти (can / be able to), Ukrainian normally uses the infinitive of the main verb, just like English often does:

• може гальмувати = can brake

So the structure is:

• [subject] + може + infinitive

Examples:

• Вона може читати. = She can read.
• Вони можуть працювати. = They can work.

Here, гальмувати means to brake.

Because the sentence needs an adverb, not an adjective.

• правильний = correct, proper (adjective; describes a noun)
• правильно = correctly, properly (adverb; describes an action)

In this sentence, правильно describes how the cyclist brakes:

• гальмувати як? — правильно
• brake how? — correctly / properly

So:

• правильний велосипедист = a proper/correct cyclist
• правильно гальмувати = to brake correctly

Велосипедист means cyclist or bike rider.

Grammatically, it is a masculine noun. It often refers to a male cyclist, but in some contexts masculine forms can also be used more generally, depending on style and situation.

If you want the clearly feminine form, you may see:

• велосипедистка = female cyclist

So:

• Велосипедист може правильно гальмувати. = The male cyclist / cyclist can brake correctly.
• Велосипедистка може правильно гальмувати. = The female cyclist can brake correctly.

In this sentence, може most naturally means can / is able to.

So the sense is about ability:

• The cyclist can brake correctly.

Depending on context, може can sometimes also mean may or even might, but here, with an infinitive and no other clues, learners should usually read it as can.

Compare:

• Він може плавати. = He can swim.
• Це може бути правдою. = That may/might be true.

Yes. Ukrainian word order is fairly flexible, although the most neutral version here is:

• Велосипедист може правильно гальмувати.

You may also hear:

• Велосипедист може гальмувати правильно.
• Правильно гальмувати велосипедист може.

These alternatives can sound more marked, with different emphasis.

A rough guide:

• Велосипедист може правильно гальмувати. = neutral
• Велосипедист може гальмувати правильно. = slightly more emphasis on the manner at the end
• Правильно гальмувати велосипедист може. = stronger emphasis, something like As for braking correctly, the cyclist can do that

So yes, the order can change, but the original sentence is the simplest standard version.

Велосипедист is in the nominative case because it is the subject of the sentence.

The other words do not show case here because:

• може is a verb form
• правильно is an adverb, and adverbs do not decline
• гальмувати is an infinitive, and infinitives do not decline

So this sentence is structurally quite simple:

• велосипедист = subject
• може = finite verb
• правильно = adverb
• гальмувати = infinitive

Гальмувати is imperfective.

That means it refers to the action in a general, ongoing, repeated, or process-oriented way. In this sentence, that fits well because it is talking about general ability:

• The cyclist can brake properly.

A perfective verb would sound more like braking successfully in a single completed event.

A common perfective partner is:

• загальмувати = to brake / to apply the brakes successfully, to come to a braking action

So:

• може правильно гальмувати = can brake properly, in general
• може правильно загальмувати = can brake properly in a particular instance / can manage to brake properly

In a basic statement about skill or ability, the imperfective гальмувати is very natural.

A helpful approximate pronunciation is:

• halʹ-mu-VA-ty

A few key points:

1. г in Ukrainian is usually pronounced like a voiced h sound, not like the hard g in go.
2. ль is a soft l.
3. The stress is on -ва-:
   • гальмува́ти

So the word sounds roughly like hal-my-VA-ty, but with a softer l and a Ukrainian-style г.

Yes. Правильно can mean:

• correctly
• properly
• sometimes the right way

In this sentence, properly may sound especially natural:

• The cyclist can brake properly.

If the context is about technique or safe riding, properly is probably the best translation. If the context is about doing something the correct way, correctly also works well.

Yes, велосипедист is a normal and standard word for cyclist.

Depending on context, people might also use descriptive phrases such as:

• той, хто їде на велосипеді = the person riding a bicycle
• велосипедист/велосипедистка = cyclist

But for a straightforward sentence like this, велосипедист is completely natural.

Yes. Ukrainian does not have articles like a and the, so велосипедист can mean either:

• a cyclist
• the cyclist

The exact meaning depends on context.

So this sentence could be understood as:

• A cyclist can brake correctly or
• The cyclist can brake correctly

English forces you to choose an article, but Ukrainian does not.

It is mainly about ability.

• Велосипедист може правильно гальмувати. = The cyclist is able to brake properly.

In some contexts, може can suggest possibility or permission, but with this sentence, the most natural reading is ability or capacity.

If you wanted a clearer permission meaning, Ukrainian would often use a different structure or a context that makes permission obvious.
