Semnătura este pe cerere.

Because Romanian usually puts the definite article at the end of the noun, not as a separate word in front of it.

• semnătură = a signature
• semnătura = the signature

This is very common in Romanian:

• carte = a book
• cartea = the book

So semnătura specifically means the signature.

Este means is. It is the 3rd person singular form of a fi = to be.

So:

• Semnătura este pe cerere = The signature is on the application/request/form

In normal speech, Romanians often shorten este to e:

• Semnătura e pe cerere

Both are correct. Este sounds a bit more full or careful; e is very common in everyday speech.

Here, pe means on.

So:

• pe cerere = on the application/request/form

Romanian pe has several uses, so learners often notice it in different contexts. For example, it can also mark direct objects with people:

• Văd pe Maria = I see Maria

But in Semnătura este pe cerere, it is simply the preposition on.

This is a very natural question, because English says on the application, with the.

In Romanian, both forms can exist, but they can sound slightly different depending on context.

• pe cerere = often a more neutral/general way to say on the application / on the form
• pe cererea = more explicitly on the specific application

In many practical or administrative contexts, Romanian often leaves the second noun without the definite article when the meaning is still clear from context.

So Semnătura este pe cerere is perfectly natural.
If you wanted to stress a particular request/application, you might also hear:

• Semnătura este pe cererea respectivă = The signature is on that specific application

The normal word order here is:

• Semnătura este pe cerere

This is the most neutral order: subject + verb + prepositional phrase.

Romanian is somewhat flexible with word order, but changing it usually changes the emphasis.

For example:

• Pe cerere este semnătura — possible, but marked; it emphasizes on the application
• Este pe cerere semnătura — unusual in normal speech

So for learners, the safest and most natural version is:

• Semnătura este pe cerere

A rough pronunciation guide is:

sem-nuh-TOO-ra ES-te pe che-RE-re

A few useful notes:

• ă is a short, neutral vowel, similar to the a in about
• e is usually like e in get
• r is trilled or tapped
• ce in cerere sounds like che in English check, but shorter and cleaner

So:

• semnătură → sem-nuh-TOO-rə
• cerere → che-RE-re

Cerere is a feminine singular noun.

It commonly means:

• request
• application
• sometimes petition, depending on context

Its forms are:

• cerere = a request / an application
• cererea = the request / the application

So in this sentence, cerere is the thing the signature is on.

Because Romanian verbs do not agree with gender in the present tense.

They agree with person and number, not with masculine/feminine.

So:

• semnătura este = the signature is
• cartea este = the book is
• masa este = the table is

All of these use este, even though the nouns are feminine.

Gender matters more for:

• articles
• adjectives
• pronouns

But not for the present-tense form of a fi here.

Yes, very much so.

Words like semnătură and cerere often appear in office, legal, or bureaucratic contexts. So the sentence can sound like something you might read or hear when dealing with documents:

• a clerk checking paperwork
• someone explaining where to sign
• someone confirming that a signed request has been submitted

That is one reason cerere may be understood as application, form, or request, depending on the situation.
