Рекомендація в резюме.

No. It is not a full sentence; it is a noun phrase.

There is no verb here. A full sentence would usually need something like є, міститься, потрібна, etc., depending on the meaning.

So this phrase is more like:

• a heading
• a label
• a topic
• part of a longer sentence

For example:

• Рекомендація в резюме важлива. = A recommendation in a résumé is important.
• Додайте рекомендацію в резюме. = Add a recommendation to the résumé.

Рекомендація is in the nominative singular form.

That is the basic dictionary form of the noun, and it is used here because it is the main word of the phrase.

Some useful forms are:

• рекомендація — nominative singular
• рекомендації — nominative plural / genitive singular
• рекомендацію — accusative singular
• рекомендацією — instrumental singular

In this phrase, рекомендація works like the title or subject: recommendation.

Because резюме is one of those Ukrainian nouns that are indeclinable.

That means its form usually stays the same in all cases.

Normally, after в meaning in, you often expect the locative case. But with резюме, the form does not visibly change:

• в резюме
• у резюме

Both are normal.

This happens because резюме is a borrowed word, and borrowed words of this type often remain unchanged.

Grammatically, after в meaning in, резюме is functioning as the locative case.

However, since резюме is indeclinable, it looks exactly the same as the dictionary form.

So the idea is:

• function: locative
• form: unchanged

This can feel strange to English speakers, because in many Ukrainian nouns the ending would change, but here it does not.

Here в means in.

Yes, you can usually also say у:

• в резюме
• у резюме

Both are correct. Ukrainian often alternates between в and у for euphony — in other words, to make pronunciation smoother.

Speakers choose whichever sounds better in context.

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

So:

• рекомендація can mean a recommendation or the recommendation
• the exact meaning depends on context

English speakers often want to insert an article mentally, but Ukrainian simply does not require one.

Sometimes, but not always exactly.

Рекомендація literally means recommendation. In CV/résumé context, it can refer to:

• a recommendation
• a reference
• a recommendation from an employer or colleague

But if you specifically mean a letter of recommendation, Ukrainian often says:

• рекомендаційний лист

And if you mean references as a section in a CV, you may also see:

• рекомендації

So in job-related contexts, the exact English translation may vary between recommendation and reference, depending on what is meant.

Approximately:

re-ko-men-DA-tsi-ya v re-zyu-ME

The main stresses are:

• рекоменда́ція
• резюме́

So the stress falls near the end in both words.

A rough English-friendly guide:

• рекоменда́ція ≈ reh-koh-men-DAH-tsi-ya
• резюме́ ≈ reh-zyoo-MEH

If this appears by itself as a title, heading, or label, capitalization is natural.

In normal running text, Ukrainian capitalization rules are similar to English in one important way: a word is capitalized at the beginning of a sentence, but common nouns are not normally capitalized in the middle just because they are important.

So:

• Рекомендація в резюме. — natural as a heading or standalone line
• У резюме є рекомендація. — lowercase inside a sentence

It is understandable, but by itself it sounds a bit like a heading or a fragment rather than a full everyday statement.

Depending on the intended meaning, a speaker might more naturally say things like:

• Рекомендація в резюме важлива.
• У резюме є рекомендація.
• Додайте рекомендації до резюме.

So the phrase itself is fine, but it most naturally functions as a label, title, or part of something longer.
