У міру того як лікування тривало, пацієнт почувався краще.

It means as, in proportion as, or the more... the more..., depending on context. In this sentence, it introduces a gradual change over time:

У міру того як лікування тривало = As the treatment continued

So the whole sentence means that the patient felt better gradually as treatment went on.

For a learner, it is best to treat it as a set conjunction. Native speakers understand it as one linking phrase that introduces a subordinate clause.

A very literal breakdown is possible:

• у міру = in measure / to the extent
• того = of that
• як = as

But in real use, you usually should not translate each part separately. Just learn the whole expression as as / in proportion as.

It comes from the noun міра (measure). In the phrase у міру, it appears in the accusative singular: міру.

This is part of an established expression, so it is easiest to memorize у міру as a chunk.

Here того is part of the full conjunction у міру того як. It helps build the meaning as / insofar as / in proportion as.

In practice, learners should treat того as part of the whole phrase rather than as a separately translated word. If you remove it, you may end up with something less standard or less natural in this exact structure.

Not here. In this sentence, як is functioning as part of the conjunction у міру того як.

So here it is closer to English as than to English how.

Лікування means treatment and is the subject of the subordinate clause.

Тривало is the past-tense form of тривати (to continue, to last). It is in the neuter singular because лікування is a neuter singular noun.

So:

• лікування = treatment
• тривало = continued / lasted

Together: the treatment continued.

Because the sentence describes an ongoing process, not a single completed event.

The idea is:

• the treatment was continuing over a period of time
• during that time, the patient was feeling better

That is exactly the kind of situation where Ukrainian normally uses the imperfective aspect.

Почувався means felt in the sense of felt physically or emotionally.

It comes from почуватися = to feel.

So:

• пацієнт почувався краще = the patient felt better

It refers to the patient’s condition or state, not to touching something with the hands.

Because the dictionary form is почуватися. The -ся is a reflexive/postfix element that is simply part of the verb.

English does not show this in the translation, so you should learn the whole verb as:

почуватися = to feel

A related fuller expression is почувати себе, and in many contexts почувався is essentially the natural short form of that idea.

Because краще here is an adverb, meaning better.

It describes how the patient felt:

• почувався краще = felt better

By contrast, кращий is an adjective meaning better as a quality of a noun:

• кращий лікар = a better doctor

So in this sentence, краще is the correct form.

Добре means well, while краще means better.

The sentence is about improvement over time, so краще is the natural choice:

• почувався добре = felt well
• почувався краще = felt better

Because the first part is a subordinate clause:

У міру того як лікування тривало

and the second part is the main clause:

пацієнт почувався краще

In Ukrainian, when the subordinate clause comes first, it is separated from the main clause by a comma. So the comma goes after тривало.

Yes. Ukrainian word order is fairly flexible.

For example, you could also say:

Пацієнт почувався краще, у міру того як лікування тривало.

That keeps the same basic meaning. The version with the subordinate clause first sounds natural and emphasizes the gradual process from the start.

Yes. One common alternative is:

Що довше тривало лікування, то краще почувався пацієнт.

This means roughly:

The longer the treatment lasted, the better the patient felt.

It is a slightly different structure, but the idea is very close.
