Таз під животом.

In Ukrainian, the present tense of to be is usually not stated in simple sentences like this.

So:

• Таз під животом = The pelvis is under the belly / abdomen

A literal word-for-word English version would sound like Pelvis under belly, but in Ukrainian that is perfectly normal.

If you wanted to express past or future, then a form of бути would appear:

• Таз був під животом = The pelvis was under the belly
• Таз буде під животом = The pelvis will be under the belly

Because the preposition під here means under in the sense of location, and with that meaning it normally requires the instrumental case.

The base form is:

• живіт = belly, abdomen

Its instrumental singular form is:

• животом

So:

• під животом = under the belly / abdomen

This is a very common pattern:

• під столом = under the table
• під ліжком = under the bed
• під небом = under the sky

Not always. Під can take two different cases, depending on meaning:

• instrumental for location: under
• accusative for motion toward a position under something

In your sentence, it is location, so you get:

• під животом = under the belly

Compare that with motion:

• покласти під живіт = to place (something) under the belly

So the difference is roughly:

• де? where? → під животом (instrumental)
• куди? to where? → під живіт (accusative)

Таз is in the nominative singular here, because it is the subject of the sentence.

So the structure is:

• Таз = subject
• під животом = prepositional phrase describing location

If this is the anatomical word pelvis, then the sentence means that the pelvis is located under the abdomen.

No. Таз can mean different things depending on context.

Common meanings include:

• pelvis in anatomy
• basin or washbasin / tub in everyday language

So out of context, таз can be ambiguous. In an anatomical sentence like Таз під животом, the intended meaning is clearly pelvis.

A rough pronunciation guide for an English speaker is:

• Таз ≈ tahz
• під ≈ peed (but with a shorter vowel and a softer final consonant)
• животом ≈ zhyh-voh-TOM

Stress:

• живот has stress on the last syllable: живі́т
• животом is stressed on the last syllable too: живото́м

So the whole sentence sounds roughly like:

• TAHZ peed zhyh-voh-TOM

The ж sound is like the s in measure.

Yes. Ukrainian word order is fairly flexible, though the most neutral version here is:

• Таз під животом

You could also say:

• Під животом таз

But that sounds more marked, as if you are emphasizing the location or using a special context.

For a basic textbook-style statement, Таз під животом is the most straightforward order.

Ukrainian has no articles.

So:

• таз can mean the pelvis, a pelvis, or just pelvis, depending on context
• живіт / животом can mean the belly, a belly, or simply belly / abdomen

English has to choose an article, but Ukrainian usually leaves that to context.

It can cover both ideas, depending on context.

• In everyday language, живіт often feels like belly
• In anatomy or more neutral description, it can also correspond to abdomen

So під животом could be understood as:

• under the belly
• under the abdomen

The best English choice depends on how technical the original context is.

Yes, especially in a descriptive, anatomical, educational, or diagram-like context.

Ukrainian often uses short nominal sentences like this:

• Серце зліва. = The heart is on the left.
• Книга на столі. = The book is on the table.
• Таз під животом. = The pelvis is under the abdomen.

It is short, natural, and complete in the present tense.
