Лікар бачить кров.

• Лікар is the subject: the person doing the action.
• бачить is the verb: the action.
• кров is the direct object: the thing being seen.

So the structure is a very normal subject + verb + object pattern.

бачить is the 3rd person singular present tense form of the verb бачити.

Its dictionary form is бачити = to see.

So бачить means:

• he sees
• she sees
• it sees
• and sometimes is seeing, depending on context

Because Ukrainian present-tense verbs do not show gender, бачить can go with either a male or a female subject.

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

So Лікар can mean:

• a doctor
• the doctor

And кров can mean:

• blood
• the blood

The exact meaning depends on context, not on a separate article word.

You know this from case and from the normal sentence pattern.

• лікар is in the nominative case, which is the usual case for the subject.
• кров is in the accusative case, which is the usual case for a direct object.

In this sentence, the word order is also the standard one, so it is very natural to read it as Doctor sees blood.

Good question. In Ukrainian, objects often appear in the accusative case, but not every noun looks different in the accusative.

кров is a feminine noun of the third declension, and its accusative singular is the same as its nominative singular:

• nominative: кров
• accusative: кров

So the noun is still in the object case here, even though the form does not visibly change.

Compare that with a noun that does change:

• книга → книгу

Yes. лікар can refer to a doctor in general, and in many contexts it can mean either a male or a female doctor.

Modern Ukrainian also has the specifically feminine form лікарка.

So you may see:

• Лікар бачить кров. = The doctor sees blood.
• Лікарка бачить кров. = The female doctor sees blood.

In your sentence, лікар by itself does not force the doctor to be male.

бачить comes from бачити, which is imperfective.

That matters because the imperfective present can mean:

• a general fact or repeated action: sees
• an action happening now: is seeing

So depending on context, the sentence could describe:

• what the doctor generally sees
• what the doctor is seeing right now

The perfective partner is usually побачити. Its form побачить means will see, not present-time sees.

No. Ukrainian word order is fairly flexible because case helps show who is doing what.

The most neutral order here is:

Лікар бачить кров.

But other orders are possible for emphasis, for example:

• Кров бачить лікар.
• Бачить лікар кров.

These are more marked and depend on style or emphasis. For a learner, subject + verb + object is the safest default.

The stress is:

• лі́кар
• ба́чить
• кров (only one syllable, so the stress is there)

A rough pronunciation guide:

• лікар ≈ LEE-kar
• бачить ≈ BAH-chytʹ
• кров ≈ krov

A couple of useful notes:

• і sounds like ee in see
• и is a different vowel from і; it is shorter and more central
• the final ь in бачить softens the final consonant

That ending shows it is a 3rd person singular present-tense verb form.

From the infinitive бачити, the present-tense forms are:

• я бачу = I see
• ти бачиш = you see
• він / вона бачить = he / she sees
• ми бачимо = we see
• ви бачите = you (plural/formal) see
• вони бачать = they see

So in your sentence, бачить matches the singular subject лікар.

Yes. Because Ukrainian has no articles, both are possible.

Without more context:

• Лікар can be the doctor or a doctor
• кров can be blood or the blood

Context tells you which one is intended.
