El titular signa aquí.

Here, titular means the holder, the named person, or the official owner/listed person for something such as an account, card, or document.

Yes, titular can also mean headline in other contexts, especially in journalism. So this is a good example of a word whose meaning depends on context. In a sentence about signing, it clearly means the person officially associated with the document.

In this sentence, titular is a noun, not an adjective.

El titular is grammatically masculine singular because of el. It can refer to:

• a male holder, literally
• or sometimes a generic holder in formal/document language

If the person is specifically female, you can say la titular.

So the word titular itself stays the same, but the article changes:

• el titular
• la titular

Signa is the 3rd person singular present indicative of signar.

That means it corresponds to he/she signs or the holder signs.

A few present-tense forms:

• jo signo = I sign
• tu signes = you sign
• ell/ella signa = he/she signs

So in this sentence, el titular signa is literally the holder signs.

Yes. The tu imperative of signar is also signa.

So:

• Signa aquí = Sign here

But in El titular signa aquí, it is understood as a normal statement, because el titular is placed before the verb as the subject.

That said, on forms and official documents, a present-tense statement like this often functions like an instruction anyway: it tells you whose signature should go there.

Catalan usually does not need subject pronouns unless there is special emphasis or contrast.

Here, the subject is already clearly stated as el titular, so adding ell or ella would be unnecessary.

Catalan often works this way:

• Signa aquí = signs here / sign here
• El titular signa aquí = the holder signs here

The verb form and/or the noun usually give enough information.

The accent shows where the stress falls: a-QUÍ.

So aquí is stressed on the last syllable. The accent mark is important in Catalan spelling because it tells you how the word should be pronounced.

It is a very common adverb meaning here.

Yes. Firmar is also used in Catalan for to sign.

In many situations, signar and firmar are close in meaning and may both sound natural, especially with documents. Usage can vary by region and context, but signa is completely normal here.

So both of these can work:

• El titular signa aquí
• El titular firma aquí

Yes, but El titular signa aquí is the most neutral and straightforward order.

It follows the basic pattern:

• subject + verb + adverb

Other orders are possible for emphasis:

• Aquí signa el titular = Here, the holder signs
• Signa aquí el titular = more marked and context-dependent

For a form or instruction, the original version is clear and natural.
