Тепла вода у ванні допомагає розслабити спину і плечі.

Because вода is a feminine noun in Ukrainian, and adjectives must agree with the noun they describe.

• теплий = masculine
• тепла = feminine
• тепле = neuter
• теплі = plural

So:

• тепла вода = warm water

The adjective changes form to match вода.

Вода is in the nominative case because it is the subject of the sentence — the thing doing the action.

In this sentence:

• Тепла вода у ванні = the subject
• допомагає = helps
• розслабити спину і плечі = relax the back and shoulders

So вода stays in its basic dictionary form: вода.

У ванні means in the bath or in the bathtub here.

A learner may notice that ванна can relate to both:

• bath / bathtub
• sometimes bathroom, depending on context

But in this sentence, тепла вода у ванні clearly means warm water in the bath.

Grammar-wise:

• у / в = in
• ванні is the locative case of ванна

So:

• ванна = bath, bathtub
• у ванні = in the bath

Ukrainian often alternates between у and в for ease of pronunciation. They usually mean the same thing: in.

So both of these are possible in many contexts:

• у ванні
• в ванні

Speakers often choose the version that sounds smoother. Since вода begins with в, using у before it helps avoid a heavy cluster of consonant sounds nearby.

This is a very common feature of natural Ukrainian.

Because after у / в meaning in, Ukrainian often uses the locative case.

So:

• ванна = bath / bathtub
• у ванні = in the bath

This is a normal case change:

• nominative: ванна
• locative: у ванні

A lot of place expressions work this way in Ukrainian.

The correct verb is допомагати = to help.

Its 3rd person singular present form is:

• допомагає = helps

So:

• вода допомагає = the water helps

This verb belongs to a common pattern where the present-tense form has -ає / -яє endings.

Because допомагати / допомогти is often followed by an infinitive, just like English help + verb.

So:

• допомагає розслабити = helps to relax

This structure is very natural in Ukrainian:

• допомагає заснути = helps (someone) fall asleep
• допомагає зрозуміти = helps (someone) understand

Here, розслабити is the infinitive: to relax.

This is a question of aspect, which is very important in Ukrainian verbs.

• розслабити = perfective, more like to relax fully / to cause relaxation
• розслабляти = imperfective, more like to be relaxing / to relax repeatedly or generally

After допомагає, Ukrainian often uses the perfective infinitive when talking about helping achieve a result:

• допомагає розслабити спину і плечі = helps relax the back and shoulders

If you used розслабляти, it would sound more like an ongoing or habitual process. The version in the sentence focuses more naturally on the result.

Because they are the direct objects of розслабити, so they appear in the accusative case.

• спина = back
• спину = back (accusative)

So:

• розслабити спину = to relax the back

For плечі:

• плечі is the plural form of плече or a plural noun meaning shoulders
• in this sentence, the accusative plural looks the same as the nominative plural: плечі

So:

• розслабити плечі = to relax the shoulders

This follows the same pattern as English.

You usually say:

• the back = singular
• the shoulders = plural

Ukrainian does the same:

• спина / спину = back
• плечі = shoulders

So розслабити спину і плечі is the natural way to say relax the back and shoulders.

Yes, і here means and.

Ukrainian also has another common word for and: та.

So you may see:

• спину і плечі
• спину та плечі

Both are correct. Sometimes speakers choose one or the other depending on style or sound.

Yes. Ukrainian word order is more flexible than English because case endings show grammatical roles.

The neutral order here is:

• Тепла вода у ванні допомагає розслабити спину і плечі.

But other orders are possible for emphasis, for example:

• У ванні тепла вода допомагає розслабити спину і плечі.
• Спину і плечі допомагає розслабити тепла вода у ванні.

These can sound more marked or literary. The original sentence is the most straightforward and natural for general use.

Because Ukrainian does not have articles like a and the.

So:

• вода can mean water, the water, or some water
• спину can mean the back
• плечі can mean the shoulders

The exact meaning is understood from context. In this sentence, English naturally uses the back and shoulders, but Ukrainian does not need separate words for the.

In standard Ukrainian, г is usually pronounced like a voiced h sound, not like the hard g in English go.

So допомагає sounds roughly like:

• do-po-ma-HA-ye

Very roughly for an English speaker.

This is important because Ukrainian has both:

• г = a softer, breathy sound
• ґ = a hard g sound

In допомагає, the letter is г, not ґ.

A useful stress guide is:

• теплá
• водá
• у вáнні
• допомагáє
• розслабúти
• спúну
• плечí

Stress is very important in Ukrainian and can sometimes shift between related forms, so it is worth learning words together with their stress.
