Kupite novo odijelo.

Yes. Kupite is the imperative form, so the sentence is a command: Buy a new suit.

More specifically, kupite is the imperative for:

• you all (plural), or
• you in a formal/polite singular sense

So Kupite novo odijelo. can mean:

• Buy a new suit. said to several people, or
• Buy a new suit. said politely to one person

It comes from kupiti, which is the perfective verb meaning to buy in the sense of completing the purchase.

This matters because Croatian often distinguishes between:

• kupiti = to buy, to make the purchase successfully
• kupovati = to be buying, to buy habitually, to do shopping

So:

• Kupite novo odijelo. suggests Buy a new suit as a completed action.
• A form from kupovati would sound more like Do some suit-buying / be buying a new suit, which is not what is meant here.

Because it agrees with odijelo, which is a neuter singular noun.

In Croatian, adjectives must agree with the noun in:

• gender
• number
• case

Here:

• odijelo = neuter singular
• so nov becomes novo

So:

• novi kaput = a new coat (masculine)
• nova haljina = a new dress (feminine)
• novo odijelo = a new suit (neuter)

It is in the accusative singular, because it is the direct object of kupite.

You are buying what?
→ novo odijelo

For many neuter inanimate nouns, the accusative looks the same as the nominative, so:

• nominative: novo odijelo
• accusative: novo odijelo

That is why there is no visible change here.

Because Croatian has no articles like English a/an/the.

So novo odijelo can mean:

• a new suit
• the new suit

Which one is meant depends on context.

In this sentence, English would usually translate it as a new suit unless the context makes it specific.

In Croatian, adjectives usually come before the noun, just like in English.

So:

• novo odijelo = new suit

This is the normal, neutral order.

Croatian word order is fairly flexible, but adjective + noun is the standard pattern here.

In isolation, kupite is most naturally understood here as an imperative: Buy a new suit.

However, forms like kupite can sometimes also match the present tense of some verbs in Croatian. In this sentence, though, with no subject stated and with this simple standalone structure, learners should read it as a command.

So the safest interpretation is:

• Kupite novo odijelo. = Buy a new suit.

It is formal if addressed to one person, and neutral plural if addressed to more than one person.

Croatian distinguishes between:

• kupi = informal singular buy!
• kupite = formal singular buy! or plural buy!

So:

• to one friend: Kupi novo odijelo.
• to one customer politely: Kupite novo odijelo.
• to several people: Kupite novo odijelo.

Odijelo usually means suit in the clothing sense, especially a matching formal outfit such as a business suit.

Depending on context, it can also more broadly refer to an outfit or set of clothes, but the most common basic meaning for learners is:

• odijelo = suit

So novo odijelo is most naturally a new suit.

It is roughly pronounced oh-dyee-yeh-loh.

The ije spelling is a normal feature of standard Croatian in many words. English speakers often want to compress it too much, but it is better to hear it as clearly separated sounds.

A rough breakdown:

• o
• di
• je
• lo

You do not need to overthink the historical reason at an early stage; the important thing is to recognize odijelo as the standard spelling and pronunciation pattern.

You could, but it would sound marked or unusual in a neutral sentence.

The normal order is:

• Kupite novo odijelo.

Putting novo after the noun changes the emphasis and would usually need a special reason, such as contrast or a poetic/stylistic effect.

For everyday Croatian, stick with:

• novo odijelo

Because Croatian usually does not need subject pronouns when the verb already shows who the subject is.

The ending in kupite already tells you that the command is for:

• you all, or
• you formal singular

So Croatian normally just says:

• Kupite novo odijelo.

not:

• Vi kupite novo odijelo.

Adding Vi is possible, but it is usually for emphasis, contrast, or extra politeness.

Not exactly.

• Kupite novo odijelo. = Buy a new suit as a completed action
• Kupujte novo odijelo. = an imperative from the imperfective verb, which can sound more like be buying a new suit, buy a new suit repeatedly, or can sometimes be used in a softer/process-oriented way

In most simple situations where someone is telling you to go and purchase one suit, kupite is the natural choice.
