Prelungirea este posibilă.

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

• prelungire = extension / prolongation
• prelungirea = the extension / the prolongation

So -a here is not just part of the basic noun; it marks the noun as definite.

The base form is prelungire.

This is a noun built from the verb a prelungi, which means to extend, to prolong, or sometimes to renew, depending on context.

So the chain is:

• a prelungi = to extend
• prelungire = extension / prolongation
• prelungirea = the extension

Because prelungirea is a feminine singular noun, and the adjective has to agree with it.

• masculine singular: posibil
• feminine singular: posibilă
• masculine plural: posibili
• feminine plural: posibile

Since prelungirea is feminine singular, the correct form is posibilă.

In standard Romanian, yes, este is normally used in a full sentence like this.

• Prelungirea este posibilă. = The extension is possible.

Romanian usually keeps the verb to be in this kind of statement. Leaving it out would sound incomplete in normal standard usage.

Yes, depending on context, English may translate it either way.

Grammatically, prelungirea is definite, so a very literal translation is the extension is possible. But in real-life English, especially in notices or administrative language, extension is possible may sound more natural.

So the best English version depends on the situation, even though the Romanian form itself is definite.

Yes. Romanian allows some flexibility.

You could also say:

• Este posibilă prelungirea.

This means essentially the same thing, but it can sound a bit more formal or slightly more focused on the idea of possibility.

• Prelungirea este posibilă. = neutral statement
• Este posibilă prelungirea. = slightly more formal or stylistically shifted

No. It is often used in administrative or abstract contexts too.

Depending on context, prelungire can refer to:

• extending a deadline
• renewing a contract
• extending a permit
• prolonging a stay
• extending a validity period

So Prelungirea este posibilă often appears in formal contexts such as offices, applications, reservations, subscriptions, visas, or deadlines.

It is an adjective.

More specifically, it is a predicate adjective, because it describes the noun prelungirea through the verb este.

Structure:

• Prelungirea = subject
• este = verb
• posibilă = adjective describing the subject

So it works like The extension is possible in English.

A rough pronunciation guide is:

preh-loon-JEE-reh-ah ES-teh poh-see-BEE-luh

A few useful points:

• ă is a short central vowel, similar to the a in sofa
• gi before i/e often sounds like English j
• este is pronounced with two clear syllables: ES-te
• posibilă ends with ă, not with a strong a

Romanian pronunciation is usually quite regular once you learn the sound system.

Yes, it sounds fairly neutral-to-formal, and it is especially common in official or practical contexts.

For example, you might see it in situations involving:

• reservations
• documents
• subscriptions
• permits
• deadlines

In casual speech, people might also say something more verbal, such as:

• Se poate prelungi. = It can be extended.

That version can sound more natural in everyday conversation, while Prelungirea este posibilă sounds a bit more formal or administrative.

The indefinite version would be:

• O prelungire este posibilă.

This means An extension is possible.

Compare:

• Prelungirea este posibilă. = The extension is possible
• O prelungire este posibilă. = An extension is possible

So the original sentence points to a specific extension, or at least presents it as identifiable in context.

The plural would be:

• Prelungirile sunt posibile. = The extensions are possible

Here the changes are:

• prelungirea → prelungirile
• este → sunt
• posibilă → posibile

This shows both noun and adjective agreement in number, and the verb changes too.
