Корінь мокрий.

In Ukrainian, the verb to be is usually left out in the present tense.

So:

• Корінь мокрий. = The root is wet.

This is completely normal Ukrainian.
If you said the same thing in the past or future, a form of бути would appear:

• Корінь був мокрий. = The root was wet.
• Корінь буде мокрий. = The root will be wet.

So the missing is is not an omission or slang — it is standard grammar.

Adjectives often do come before nouns in Ukrainian when they directly describe a noun:

• мокрий корінь = a wet root / the wet root

But in Корінь мокрий, the adjective is not just attached to the noun — it is acting as the predicate of the sentence:

• Корінь мокрий. = The root is wet.

So the difference is:

• мокрий корінь = a noun phrase, wet root
• корінь мокрий = a full sentence, the root is wet

This is a very important distinction.

Because it must agree with корінь in gender, number, and case.

Here:

• корінь is masculine
• it is singular
• it is in the nominative case

So the adjective also has to be:

• masculine
• singular
• nominative

That gives мокрий.

Compare:

• корінь мокрий — masculine singular
• трава мокра — feminine singular
• листя мокре — neuter singular
• корені мокрі — plural

It is in the nominative case.

That is because корінь is the subject of the sentence:

• Корінь мокрий. = The root is wet.

The adjective мокрий is also in the nominative because it agrees with the subject in this kind of sentence.

Ukrainian does not have articles like English a/an/the.

So корінь can mean:

• a root
• the root

The exact meaning depends on context.

In a standalone sentence like Корінь мокрий, English will often use the:
The root is wet.

But Ukrainian itself does not mark that difference with an article.

Yes. Корінь is a masculine noun.

For English speakers, this can be confusing because nouns ending in -ь are not all the same gender. Some are masculine, some are feminine, so you usually have to learn the gender with the word.

Here, корінь is masculine, which is why the adjective is мокрий, not мокра or мокре.

A rough guide is:

• корі́нь ≈ ko-RIN’
• мо́крий ≈ MO-kryi

A few helpful points:

• The stress is корі́нь мо́крий
• і sounds like English ee in see
• и is a short Ukrainian vowel, not exactly like English ee or ih
• The soft sign ь in корінь softens the final н

A rough overall pronunciation might be:

• ko-RIN’ MO-kryi

Yes, but it means something slightly different in structure.

• Мокрий корінь = wet root
  This is a noun phrase, not a full statement by itself.
• Корінь мокрий. = The root is wet.
  This is a complete sentence.

So if you are labeling or naming something, мокрий корінь is fine.
If you are making a statement, корінь мокрий is the natural pattern.

Not always. Корінь can mean root in several senses, depending on context, for example:

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

In Корінь мокрий, the adjective мокрий strongly suggests a physical root, such as a plant root, because something being wet is usually literal here.

Yes. It is short, simple, and natural.

Ukrainian often allows very compact sentences like this:

• Земля суха. = The soil is dry.
• Вода холодна. = The water is cold.
• Корінь мокрий. = The root is wet.

This kind of structure is basic and very common.
