Хребет підтримує голову.

Here хребет means the spine, backbone, or spinal column.

A learner should know that хребет can also mean a ridge (for example, a mountain ridge) in other contexts, but in this sentence it clearly means the spine/backbone because it is connected with голову (the head).

It is a masculine singular noun in the nominative case, because it is the subject of the sentence.

Because голову is in the accusative case, not the nominative.

• голова = nominative singular, used for the subject
• голову = accusative singular, used for the direct object

In this sentence, the spine is doing the action, and the head is receiving the action:

• Хребет = subject
• підтримує = supports
• голову = direct object

So Ukrainian changes голова to голову.

Підтримує is the 3rd person singular present tense form of підтримувати (to support).

So it means:

• he/she/it supports
• or, in this sentence, supports

Because хребет is singular, the verb is also singular.

This is a very common pattern in Ukrainian:

• він читає = he reads
• вона знає = she knows
• хребет підтримує = the spine supports

In Ukrainian, the present tense is often used for general truths, scientific facts, and habitual actions, just like in English.

So Хребет підтримує голову means something like:

• The spine supports the head
• The spine is what supports the head

This is a normal use of the present tense.

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

So:

• хребет can mean a spine or the spine
• голову can mean a head or the head

The exact meaning comes from context. In this sentence, English naturally uses the spine and the head, but Ukrainian does not need separate words for that.

The word order Хребет підтримує голову is the most neutral and straightforward order:

subject + verb + object

That is the most natural way to present a basic statement.

However, Ukrainian word order is more flexible than English. For example, you could also say:

• Голову підтримує хребет

This still means the same thing, but it shifts the emphasis. It may sound like you are contrasting or highlighting what supports the head.

So the original order is the plain, neutral one.

Yes. Підтримувати is a transitive verb, so it normally takes a direct object in the accusative case.

That is why we get:

• підтримує голову
• not підтримує голова

This is a useful grammar pattern to remember:

• transitive verb -> direct object -> usually accusative

A helpful pronunciation guide is:

Khre-BET pid-try-MU-ye ho-lo-VU

More carefully:

• Хребет ≈ khre-BET
• підтримує ≈ pid-try-MU-ye
• голову ≈ ho-lo-VU

The stress is usually:

• хребе́т
• підтри́мує
• голову́

A few sound notes for English speakers:

• х is like a throaty h/kh sound, not exactly English h
• и is not the same as English ee
• є in підтримує gives a ye-like sound

Not exactly.

Хребет specifically means the spine/backbone.
English back is broader and often refers to the whole back area of the body.

So in anatomy:

• хребет = spine, backbone
• спина = back

In this sentence, хребет is the correct word because it is the structure that supports the head.

Голова is a feminine noun.

Yes, that matters because feminine nouns often change in a particular way in the accusative singular. For many feminine nouns ending in -а, the ending changes to -у:

• книга -> книгу
• рука -> руку
• голова -> голову

So this sentence is a good example of a very common feminine noun pattern.

In theory, підтримувати can mean to support in many senses, including figurative ones. But in this sentence, because the subject is хребет and the object is голову, the meaning is clearly physical/anatomical.

So a learner should understand it literally:

The spine supports the head.

The dictionary forms are:

• хребет -> хребет
• підтримує -> підтримувати
• голову -> голова

This is useful because when you look words up, verbs are usually listed in the infinitive and nouns in the nominative singular.
