Куртка вам пасує.

Пасує is the 3rd person singular form of пасувати. In this sentence, it means suits, looks good on, or is becoming on someone.

That is different from подобається:

• Куртка вам пасує = the jacket suits you / looks good on you
• Куртка вам подобається = you like the jacket

So пасує is about suitability or appearance, while подобається is about personal liking.

Because пасувати takes the dative case for the person.

So Ukrainian treats the person as to you, not as a direct object:

• вам = dative
• вас = accusative or genitive, which would be wrong here

This is a very common Ukrainian pattern with verbs of feeling, suitability, or perception.

It can mean either:

• you when speaking politely to one person
• you all when speaking to more than one person

So Куртка вам пасує could mean:

• The jacket suits you said politely to one person
• The jacket suits you said to several people

Context tells you which meaning is intended.

You would say:

Куртка тобі пасує.

Here:

• тобі = informal singular to you
• вам = formal singular or plural to you

So the sentence changes only in the pronoun.

In normal running text, вам is usually written with a lowercase letter.

Capitalized forms like Вам, Ваш, Вас are mainly a politeness convention in:

• letters
• emails
• formal messages
• direct respectful address to one person

So lowercase вам in this sentence is completely normal.

Куртка is in the nominative case because it is the subject of the sentence.

The structure is basically:

• Куртка = the jacket
• вам = to you
• пасує = suits

So the jacket is the thing that does the suiting, grammatically speaking.

Because its subject, куртка, is singular.

In the present tense, Ukrainian verbs agree with the subject in person and number. They do not show gender in the present tense.

So:

• Куртка вам пасує = singular subject
• Куртки вам пасують = plural subject

No. Nothing is missing.

Пасує is already the full verb, so the sentence is complete.

Learners sometimes expect a form like is, but Ukrainian only omits present-tense є in sentences like:

• Куртка гарна = The jacket is nice

Here, though, the verb is пасує, so no extra є is needed.

Yes. Ukrainian word order is flexible.

These are all possible:

• Куртка вам пасує.
• Вам пасує куртка.
• Пасує вам куртка?

The most neutral version here is Куртка вам пасує.

Changing the order usually changes the focus or emphasis, not the basic meaning.

Usually пасувати means that something suits someone in appearance, style, color, or general effect.

It can sometimes overlap with fit, but if you want to be specific about size or cut, Ukrainian often uses other expressions, such as:

• Куртка вам якраз. = The jacket is just the right size for you.
• Куртка вам добре сидить. = The jacket fits you well / sits well on you.
• Куртка підходить вам за розміром. = The jacket fits you size-wise.

So пасує is usually more about suiting than strict measurements.

For the negative, add не before the verb:

Куртка вам не пасує.

For a yes/no question, Ukrainian usually just uses intonation in speech, and a question mark in writing:

Куртка вам пасує?

You can also change the order for emphasis:

Вам пасує куртка?

Unlike English, you do not need an extra verb like does.
