Carosabilul este închis.

Not exactly. Carosabilul refers specifically to the carriageway / roadway — the part of the street or road used by vehicles.

So it is a bit more technical than the everyday English word road. It does not include things like the sidewalk.

In many real-life contexts, though, it may still be translated simply as the road if that sounds more natural in English.

Because Romanian usually puts the definite article at the end of the noun.

• carosabil = a roadway / roadway
• carosabilul = the roadway

The ending -ul is the masculine/neuter singular definite article here.

This is one of the big differences from English: Romanian often says the by attaching it to the noun instead of putting a separate word before it.

The base noun carosabil is a neuter noun in Romanian.

In Romanian, neuter nouns behave:

• like masculine in the singular
• like feminine in the plural

So in the singular you get forms like:

• un carosabil
• carosabilul

That is why it looks masculine in this sentence.

Este is the 3rd person singular of the verb a fi = to be.

So:

• carosabilul = the roadway
• este = is
• închis = closed

Together: The roadway is closed.

Romanian uses a fi here just like English uses to be in is closed.

Yes. E is a very common shorter form of este.

So both are correct:

• Carosabilul este închis.
• Carosabilul e închis.

The version with este can feel a bit more formal or neutral in writing, while e is very common in everyday speech.

Because închis has to agree with the noun it describes.

Since carosabilul is singular and behaves as masculine in the singular, the adjective/past participle also appears in the masculine singular form:

• masculine singular: închis
• feminine singular: închisă
• masculine plural: închiși
• feminine/neuter plural: închise

So:

• carosabilul este închis but
• strada este închisă because strada is feminine

It can be understood as a past participle used predicatively, very similar to an adjective in this sentence.

So este închis means is closed.

In practice, a learner can safely read it as a normal description of state:

• the roadway is closed

Romanian often uses past participles this way:

• ușa este deschisă = the door is open
• magazinul este închis = the shop is closed

The basic word order is:

subject + verb + complement

• Carosabilul = subject
• este = verb
• închis = complement/predicative adjective

So the sentence is in a very normal, neutral order: Carosabilul este închis.

Romanian word order is somewhat flexible, but this is the standard unmarked version.

A rough pronunciation guide is:

kah-roh-sah-BEE-lool ES-teh uhn-KEESH

A few useful notes:

• c before a sounds like k
• ș would sound like sh, but there is no ș in this sentence
• ch in închis sounds like k
• î is a special Romanian vowel, pronounced deep and central; English has no exact equivalent

A more careful approximation:

• carosabilul → kah-roh-sah-BEE-lul
• este → ES-te
• închis → uhn-KEESh

Yes, absolutely.

Drumul este închis means the road is closed and is more everyday language.

Compared with that:

• drum = general everyday word for road
• carosabil = more specific/technical word for the drivable roadway

So Carosabilul este închis may sound more formal, official, or like signage/traffic language.

It can mean both, depending on context.

For example:

• Magazinul este închis = The shop is closed
• Ușa este închisă = The door is closed/shut
• Carosabilul este închis = The roadway is closed

So in this sentence, închis clearly means closed to use/traffic, not necessarily physically sealed.
