Catalogul arată un exemplar disponibil în secțiune.

In Romanian, the definite article is usually attached to the end of the noun, not placed in front of it as a separate word.

• catalog = catalog
• catalogul = the catalog

So catalogul means the catalog.

Arată is the 3rd person singular present form of the verb a arăta, which can mean to show, to display, or sometimes to look.

In this sentence, it means shows/displays because it has a direct object:

• Catalogul arată... = The catalog shows...

Notable forms:

• eu arăt = I show
• tu arăți = you show
• el/ea arată = he/she/it shows

Yes. That is something English speakers often notice.

A arăta can mean:

• to show / display
• to look / appear

The meaning depends on context.

Examples:

• Catalogul arată un exemplar disponibil. = The catalog shows an available copy.
• El arată obosit. = He looks tired.

In your sentence, the presence of un exemplar disponibil makes it clear that arată means shows.

Exemplar often means copy, specimen, or item, depending on context.

In a catalog or library context, it usually means:

• a copy of a book
• an item in stock
• a particular экземпляр/item record

So un exemplar disponibil means something like an available copy.

Un is the indefinite article, meaning a/an.

• exemplar = copy / specimen
• un exemplar = a copy / an item

Romanian uses un for masculine and neuter singular nouns in the indefinite form.

Exemplar is a neuter noun in Romanian.

Neuter nouns behave:

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

That is why you get:

• singular: un exemplar disponibil
• plural: două exemplare disponibile

So yes, the adjective agrees with the noun, but in the singular the neuter pattern looks the same as masculine.

In Romanian, adjectives often come after the noun.

So:

• un exemplar disponibil = an available copy

This is the normal, neutral order. Romanian can sometimes place an adjective before the noun, but that usually adds emphasis or a stylistic effect.

This is a good question, because English speakers often expect the section.

Romanian can sometimes leave the noun without the definite article in short labels, technical phrasing, or institutional/database-style language. So în secțiune can sound like a compact system message.

However, if you mean a specific section in more natural everyday Romanian, în secțiunea... is often clearer:

• în secțiunea de literatură
• în secțiunea respectivă

So the sentence as given is understandable, but in fuller or more natural phrasing you may often see a definite or more specific form.

Yes. It follows a very common Romanian pattern:

Subject + Verb + Object + Adjective phrase + Prepositional phrase

Breaking it down:

• Catalogul = subject
• arată = verb
• un exemplar disponibil = object + adjective
• în secțiune = prepositional phrase

So the structure is straightforward and natural for Romanian.

A few pronunciation points are especially useful here:

• ă is a short central vowel, similar to the a in sofa
• ț is pronounced ts, like in cats

So:

• arată is roughly uh-RAH-tuh
• secțiune is roughly sek-TSYOO-neh

The exact Romanian pronunciation is smoother than these English approximations, but those will get you close.

Yes. In everyday speech or in a fuller written sentence, you might also hear something like:

• Catalogul arată că există un exemplar disponibil în secțiune.
• Catalogul indică un exemplar disponibil în secțiune.

These versions sound a bit more explicit. The original sentence sounds somewhat compact, like interface language, a system message, or a catalog entry.

The main Romanian features to notice are:

1. Definite article attached to the noun

   • catalogul = the catalog

2. Verb conjugation

   • arată = shows

3. Adjective usually after the noun

   • exemplar disponibil = available copy

4. Agreement

   • disponibil matches exemplar

5. Romanian can sound more compact than English

   • especially in catalog, interface, or administrative language

If you understand those five points, you understand most of the grammar in this sentence.
