Târgul de vechituri este deschis.

Because -ul is the definite article in Romanian.

• târg = market / fair
• târgul = the market / the fair

Unlike English, Romanian usually puts the definite article at the end of the noun instead of using a separate word like the.

So:

• Târgul de vechituri = the flea market
• Un târg de vechituri = a flea market

De usually means of or for, and vechituri means old things, junk, or second-hand items.

So târg de vechituri is literally something like:

• market of old things
• or more naturally, flea market

This is a fixed-type expression in Romanian. English uses a special idiomatic term, but Romanian describes it more literally.

Because Romanian attaches the definite article to the noun itself.

Compare:

• English: the market
• Romanian: târgul

This is very common in Romanian:

• băiat = boy

• băiatul = the boy

• magazin = shop
• magazinul = the shop

So in Târgul de vechituri, the the is already built into târgul.

Deschis agrees with târgul, which is a masculine singular noun.

In Romanian, adjectives often change form to match the noun’s gender and number.

Here:

• târgul = masculine singular
• so: deschis = masculine singular form of open

Compare:

• magazinul este deschis = the shop is open
• ușa este deschisă = the door is open

Here ușa is feminine singular, so the adjective becomes deschisă.

Usually, in a normal full sentence like this, este is kept:

• Târgul de vechituri este deschis.

In casual speech, Romanians sometimes drop forms of a fi (to be) in certain contexts, but for learners, it is best to use este here.

So the standard, correct full sentence is:

• Târgul de vechituri este deschis.

Yes. E is a very common short form of este in everyday Romanian.

So both are correct:

• Târgul de vechituri este deschis. = more formal/neutral
• Târgul de vechituri e deschis. = more natural in casual speech

Learners should understand both.

A rough English-friendly guide is:

TUR-gool deh veh-kee-TOO-ree

A few important sounds:

• â is a Romanian vowel with no exact English equivalent; it is a central sound, somewhat like a muted u.
• ă (not in this sentence, but common in Romanian) is different from â.
• ch in deschis is pronounced like k here, because it comes before i:
  deschis sounds roughly like dess-KEES.

A more careful breakdown:

• Târgul ≈ TUR-gool
• de ≈ deh
• vechituri ≈ veh-kee-TOO-ree
• este ≈ YES-teh
• deschis ≈ dess-KEES

Because vechituri refers to old items / second-hand things / junk as a collection.

Romanian often uses the plural in expressions like this when talking about a category of objects. So târg de vechituri is a market where many old items are sold.

The singular vechitură means something like:

• an old useless object
• a piece of junk

But in this expression, the plural vechituri is the normal form.

In this sentence, it functions like an adjective, even though historically it comes from the past participle of a deschide (to open).

So:

• a deschide = to open
• deschis = opened / open

In este deschis, the natural English translation is is open, not is opened.

This is very common in Romanian, just as in English we say:

• The shop is open not usually
• The shop is opened

Yes, Romanian word order is somewhat flexible, but the normal, neutral order here is:

• Târgul de vechituri este deschis.

You might sometimes see or hear variations for emphasis, such as:

• Este deschis târgul de vechituri.

But that sounds less neutral and more context-driven, something like The flea market is open with special emphasis.

For learners, the original order is the safest and most natural.

You make it negative by putting nu before the verb:

• Târgul de vechituri nu este deschis. = The flea market is not open.

In everyday speech:

• Târgul de vechituri nu e deschis.

Both are correct.

You can usually keep the same word order and change the intonation in speech:

• Târgul de vechituri este deschis? = Is the flea market open?

In casual speech:

• Târgul de vechituri e deschis?

Romanian does not usually need inversion like English does. English changes The market is open to Is the market open?, but Romanian can often just use rising intonation.

Not always. Târg can mean a fair, market, or sometimes a traditional marketplace/event, depending on context.

In târg de vechituri, it clearly refers to a flea market.

So while market is a useful translation, it is good to remember that târg can have a slightly broader cultural meaning than the English word market in some contexts.
