Бур'ян має довгий корінь, так що ми копаємо обережно.

In Ukrainian, the apostrophe is not a quotation mark. It shows that the consonant before it stays hard and is not softened by the following vowel.

So in бур'ян, the я is pronounced more like ya, and the р before it does not soften the way it might in some other words.

This is a common feature in Ukrainian words like:

• ім'я — name
• п'ять — five
• бур'ян — weed

It helps with pronunciation more than meaning.

A learner-friendly approximation is boor-YAHN.

A few notes:

• у sounds like oo in food
• я after the apostrophe sounds like ya
• the stress is on the last syllable: бур'Ян

So: бур'Ян.

Має is the 3rd person singular form of мати — to have.

Here:

• бур'ян = weed
• має = has

So Бур'ян має... literally means The weed has...

This is completely normal Ukrainian. Ukrainian can express possession in different ways depending on context, but with something like a weed has a long root, мати is the straightforward choice.

Because корінь is:

• masculine
• singular
• here in the nominative case

The adjective must match the noun, so:

• довгий = masculine singular nominative
• корінь = masculine singular nominative

So they agree: довгий корінь.

If the noun changed, the adjective would change too. For example:

• довга трава — long grass
• довге стебло — a long stem

Because it is the thing being described as the thing the weed has.

In Бур'ян має довгий корінь:

• бур'ян is the subject
• має is the verb
• довгий корінь is the direct object

In many Ukrainian grammar explanations, after мати, the thing possessed is treated as a direct object, and in modern Ukrainian that usually looks like the same form as nominative for inanimate masculine singular nouns like корінь? Actually, here we should be careful: корінь as an inanimate masculine singular noun has the same form in nominative and accusative. So the object form is accusative, but it looks identical to nominative.

That is why you see:

• nominative: корінь
• accusative: корінь

So grammatically it is the accusative, but the form does not change.

Так що means so, so that, or therefore, depending on context.

In this sentence, it introduces the result:

• the weed has a long root,
• so we dig carefully.

So here it works like so or therefore in English.

It connects the two parts of the sentence logically: cause/result:

• long root → careful digging

Because так що is introducing a new clause.

The sentence has two parts:

• Бур'ян має довгий корінь
• ми копаємо обережно

They are linked by так що, so Ukrainian normally separates them with a comma.

This is very similar to English punctuation in a sentence like:

• The weed has a long root, so we dig carefully.

Копаємо is the 1st person plural form of копати — to dig.

So:

• я копаю — I dig
• ти копаєш — you dig
• ми копаємо — we dig

The ending -ємо tells you the subject is we.

That is why ми is used here: it matches копаємо.

Yes. Ukrainian often drops subject pronouns when the verb ending already makes the subject clear.

So both are possible:

• ...так що ми копаємо обережно.
• ...так що копаємо обережно.

The version with ми is a bit more explicit. It can add slight emphasis or simply sound more natural in a particular context.

Because it describes how we dig, so Ukrainian uses an adverb.

• обережний / обережна / обережне / обережні = careful, cautious
• обережно = carefully, cautiously

Here the word modifies the verb копаємо:

• копаємо як? — обережно
• dig how? — carefully

So обережно is the correct form.

No, they mean different things.

• так що = so, therefore, as a result
• тому що = because

Compare:

• Бур'ян має довгий корінь, так що ми копаємо обережно.
  The weed has a long root, so we dig carefully.

• Ми копаємо обережно, тому що бур'ян має довгий корінь.
  We dig carefully because the weed has a long root.

They express the same general idea, but the logic is framed differently:

• так що gives the result
• тому що gives the reason

Yes, Ukrainian word order is fairly flexible, though some orders sound more neutral than others.

The given sentence is a normal, neutral version:

• Бур'ян має довгий корінь, так що ми копаємо обережно.

You could also hear variations for emphasis, such as:

• Ми копаємо обережно, бо бур'ян має довгий корінь.
• Обережно ми копаємо, бо бур'ян має довгий корінь. — more marked, with emphasis on carefully

Even when word order changes, the case endings and verb forms help show the relationships between words.

No. Корінь has several meanings, just like root in English.

It can mean:

• the root of a plant
• the root of a word in grammar
• a root in mathematics

In this sentence, because of бур'ян and копаємо, it clearly means a plant root.

Context usually makes the meaning obvious.
