Будь ласка, говори голосніше, бо я тебе не розумію.

Будь ласка is the standard polite way to say please in Ukrainian.

Literally, it comes from older wording related to be so kind or if you please, but in modern Ukrainian you should just learn it as a fixed expression meaning please.

It can appear in different places in a sentence:

• Будь ласка, говори голосніше.
• Говори, будь ласка, голосніше.
• Говори голосніше, будь ласка.

All are natural, though the first one is very common.

Говори is the imperative form for speaking to one person informally: a friend, child, relative, classmate, etc.

Говоріть is used:

• for more than one person
• or for one person formally/politely

So:

• Говори голосніше = speak louder (to one person, informal)
• Говоріть голосніше = speak louder (to several people, or to one person formally)

If you wanted the whole sentence to be formal, you would usually say:

Будь ласка, говоріть голосніше, бо я вас не розумію.

Говорити means to speak / to talk, while казати means to say / to tell.

In this sentence, the speaker wants the other person to make their speech louder in general, so говори голосніше is the most natural choice.

Compare:

• Говори голосніше = Speak louder
• Скажи ще раз = Say it again
• Кажи повільніше can exist colloquially, but it feels more like say things more slowly rather than speak more loudly

So говори is the best fit here.

It is the imperative singular of говорити.

That means it is the form used to give a command, request, or instruction to one person.

Some useful related forms:

• говорити = to speak
• ти говориш = you speak
• говори = speak! (informal singular)
• говоріть = speak! (formal singular or plural)

Because this is a request for an ongoing way of speaking, the imperfective verb говорити is exactly what you would expect.

Голосніше means louder or more loudly.

It is the comparative form built from голосно = loudly.

So:

• голосно = loudly
• голосніше = louder / more loudly

In English, louder can describe either an adjective or an adverb, but here in Ukrainian it is functioning adverbially: it tells us how to speak.

Compare:

• Говори голосно = Speak loudly
• Говори голосніше = Speak louder

Because Ukrainian often builds the comparative directly into the word itself.

English can say:

• loud
• louder
• or more loudly

Ukrainian usually expresses this with one comparative form:

• голосно → голосніше

So голосніше already contains the idea of more loudly.

Yes, тому що would also be correct.

Бо means because and is very common in everyday speech. It is short and natural.

So these are both fine:

• Будь ласка, говори голосніше, бо я тебе не розумію.
• Будь ласка, говори голосніше, тому що я тебе не розумію.

The version with бо sounds a bit more conversational and compact.

Because розуміти takes a direct object, and that object must be in the accusative case.

• ти = you as the subject
• тебе = you as the object

So:

• Ти говориш = You are speaking
• Я тебе не розумію = I do not understand you

This is one of the most important pronoun patterns to learn.

A quick comparison:

• я → мене
• ти → тебе
• ми → нас
• ви → вас

In this sentence, no special change is needed: тебе stays the normal object form used with розуміти.

Ukrainian negation can sometimes interact with case choices in certain constructions, but with розуміти кого? що? the object here is naturally accusative, so тебе is exactly what you expect.

So just learn:

• Я розумію тебе
• Я не розумію тебе
• more naturally in everyday word order: Я тебе не розумію

Because Ukrainian present tense covers what English often expresses with the simple present.

Я тебе не розумію literally uses present tense, and that is exactly how Ukrainian says I don’t understand you.

Ukrainian does not need a separate helper like English do:

• I do not understand
• Ukrainian: Я не розумію

It can also cover what English sometimes expresses as I’m not understanding you, but in normal translation I don’t understand you is best.

There are two commas for two different reasons.

1. Будь ласка is often set off with a comma because it functions like a polite parenthetical expression:

   • Будь ласка, говори голосніше

2. A comma is normally placed before бо when it introduces the reason clause:

   • ..., бо я тебе не розумію

So the punctuation is standard: Будь ласка, говори голосніше, бо я тебе не розумію.

Yes. Ukrainian word order is more flexible than English word order, although not completely free.

The original sentence is very natural:

• Будь ласка, говори голосніше, бо я тебе не розумію.

But you could also hear:

• Говори, будь ласка, голосніше, бо я тебе не розумію.
• Я тебе не розумію, тож говори голосніше.
• Бо я тебе не розумію, говори, будь ласка, голосніше.

Changing the order usually changes emphasis, not the core meaning.

Yes, this version is informal because of говори and тебе.

To say it politely or formally to one person, use:

• Будь ласка, говоріть голосніше, бо я вас не розумію.

Changes:

• говори → говоріть
• тебе → вас

This is the version you would use with a stranger, teacher, older person, or in a formal situation.

A few stress points are especially useful:

• будь ла́ска
• говори́
• голосні́ше
• тебе́
• розумі́ю

A rough pronunciation guide:

• будь ласка ≈ bood LAS-ka
• говори ≈ ho-vo-RY
• голосніше ≈ ho-lo-SNEE-she
• розумію ≈ ro-zu-MEE-yu

Also note that Ukrainian г is usually pronounced like a soft h sound, not a hard English g. So говори begins more like h than g.
