Навичка корисна.

In Ukrainian, the verb to be is usually omitted in the present tense in simple statements like this.

So:

Навичка корисна
literally: Skill useful
natural English: A skill is useful or The skill is useful

This is completely normal Ukrainian, not an incomplete sentence.

Because Ukrainian adjectives must agree with the noun they describe in gender, number, and case.

Навичка is:

• feminine
• singular
• nominative

So the adjective must also be:

• feminine
• singular
• nominative

That gives корисна.

Compare:

• корисний = masculine
• корисна = feminine
• корисне = neuter
• корисні = plural

A very common sign of a feminine noun in Ukrainian is the ending -а or -я in the dictionary form.

So навичка is feminine.

That is why it pairs with feminine forms like:

• корисна
• нова
• важлива

For example:

• Нова навичка
• Важлива навичка

It is in the nominative singular.

Why? Because it is the subject of the sentence: the thing being talked about.

Also, this is the dictionary form of the noun, so if you look up навичка in a dictionary, this is the form you will find.

It is an adjective.

Even though in English we say is useful, in Ukrainian the adjective can stand directly after the noun in this kind of sentence:

Навичка корисна = The skill is useful

So корисна is still an adjective, just used as the predicate of the sentence.

A learner might confuse it with корисно, but that is different:

• корисна agrees with a feminine noun
• корисно is used in other structures, for example Це корисно = This is useful

So Навичка корисно would be incorrect.

It means skill.

This is an important distinction because навичка looks similar to звичка, which means habit.

So:

• навичка = skill
• звичка = habit

For an English speaker, this is a very common mix-up.

It can mean either one, depending on context.

Ukrainian does not have articles like English a and the, so the sentence itself does not mark that distinction.

Depending on the situation, it could be understood as:

• A skill is useful
• The skill is useful
• This skill is useful if the context already makes that clear

If you want to be more specific, Ukrainian can add words like:

• ця навичка = this skill
• та навичка = that skill

Word order in Ukrainian is fairly flexible, but these two forms are usually understood differently:

• Навичка корисна = The skill is useful
  This is a full sentence.

• Корисна навичка = a useful skill
  This is usually just a noun phrase, not a full sentence.

So the same two words can form either:

• a sentence, or
• a descriptive phrase

depending on the order and context.

A rough pronunciation is:

NA-vych-ka ko-RYS-na

A few helpful points:

• ч sounds like ch in church
• ш is not present here, so do not make it sound like sh
• Ukrainian и is not the same as English ee; it is shorter and more central
• the stress is on НА in навичка and on РИС in корисна

So say it roughly as:

NA-vych-ka ko-RYS-na

The adjective changes to match the noun.

Examples:

• Навички корисні = Skills are useful
  plural noun → plural adjective

• Метод корисний = The method is useful
  masculine noun → masculine adjective

• Завдання корисне = The task is useful
  neuter noun → neuter adjective

So the pattern is:

• feminine: корисна
• masculine: корисний
• neuter: корисне
• plural: корисні
