Propustili smo povezani let.

Croatian past tense is often built with:

• a past participle: propustili
• plus a form of to be: smo = we are/have in this tense structure

So propustili smo is the normal way to say we missed.

The verb is propustiti, which means to miss, to fail to catch, or to let slip. In this sentence, it means missing a flight connection.

Because smo is a clitic. In Croatian, clitics usually go in the second position of the sentence or clause.

So with no subject pronoun stated, the first main word is propustili, and smo comes right after it:

• Propustili smo povezani let.

If you include the pronoun mi for emphasis, then you get:

• Mi smo propustili povezani let.

Both are correct.

Croatian often drops subject pronouns when they are already clear from the verb phrase.

Here, smo already tells you the subject is we, so mi is not necessary.

• Propustili smo povezani let. = normal, neutral
• Mi smo propustili povezani let. = more emphatic, like we missed it

The past participle agrees with the gender and number of the subject.

• propustili = masculine plural, or a mixed-gender group
• propustile = feminine plural

So:

• Propustili smo povezani let. = said by men or a mixed group
• Propustile smo povezani let. = said by a group of women

This is a very common feature of Croatian past tense.

Propustiti is perfective.

That fits this sentence well, because missing the flight is seen as a completed event: it happened, and it is over.

Its imperfective partner is propuštati, which would be used more for repeated, ongoing, or habitual missing, depending on context.

So in this sentence, propustiti is the natural choice.

Let is in the accusative singular because it is the direct object of propustili smo.

However, let is a masculine inanimate noun, and for many masculine inanimate nouns in Croatian:

• nominative singular = accusative singular

So:

• let = subject form
• let = object form too

That is why it looks the same here.

Because the adjective has to agree with let in:

• gender: masculine
• number: singular
• case: accusative

Since let is masculine singular accusative, the adjective matches it:

• povezani let

So the adjective is not agreeing with we. It is agreeing with flight.

It is understandable and can be used, especially in more formal or travel-related language.

However, in everyday speech, speakers may also say things like:

• let s presjedanjem = a flight with a transfer
• veza = connection

So depending on context, you may also hear:

• Propustili smo vezu. = We missed the connection.

In other words, povezani let works, but it is not the only natural way to express the idea.

No. Croatian word order is fairly flexible.

The version you have:

• Propustili smo povezani let.

is a neutral way to say it.

But word order can change for emphasis:

• Mi smo propustili povezani let. = emphasizes we
• Povezani let smo propustili. = emphasizes the connecting flight

So the meaning stays basically the same, but the focus changes.

Because Croatian does not have articles like a or the.

So Croatian simply says:

• povezani let

and context tells you whether English should use a connecting flight or the connecting flight.

Here, English naturally uses the because the specific flight is understood from the situation.
