El justificant confirma la domiciliació bancària amb el beneficiari.

In this sentence, justificant is a noun, not a verb form. It usually means something like:

• receipt
• proof
• supporting document
• voucher

The exact English choice depends on context. It comes from justificar (to justify / to prove), so a justificant is basically a document that proves something.

Domiciliació bancària is a common banking expression. It refers to a payment arrangement connected to a bank account, usually what English calls a direct debit or an automatic bank payment.

A learner might notice that domiciliació looks related to domicile or address. Historically that connection is there, but in modern banking Catalan, the phrase is best learned as a fixed expression.

Because bancària must agree with domiciliació.

In Catalan, adjectives usually match the noun in:

• gender
• number

Here:

• domiciliació is feminine singular
• so the adjective is bancària, also feminine singular

Compare:

• servei bancari = banking service / bank service
• domiciliació bancària = bank direct debit

Because that is the normal position for many adjectives in Catalan.

So Catalan often says:

• noun + adjective

Examples:

• compte bancari = bank account
• transferència internacional = international transfer
• domiciliació bancària = bank direct debit

English often puts adjectives before the noun, but Catalan very often puts them after it.

Confirma is the third-person singular present indicative of confirmar (to confirm).

So:

• jo confirmo = I confirm
• tu confirmes = you confirm
• ell/ella confirma = he/she confirms

In the sentence, the subject is el justificant, which is singular, so the verb is confirma.

Catalan usually does not need a subject pronoun like ell here, because the verb ending already shows the person and number.

Amb usually means with.

So amb el beneficiari means with the beneficiary or in relation to the beneficiary. In this sentence, it links the banking arrangement to the beneficiary/payee.

A useful thing to remember is that prepositions do not always match English one-for-one. In other banking contexts, Catalan might use a different preposition depending on the exact meaning. But in this sentence, you should understand amb el beneficiari as the phrase chosen to connect the direct debit and the beneficiary.

Because amb does not contract with el.

Catalan has some common contractions:

• a + el = al
• de + el = del
• per + el = pel

But:

• amb + el = amb el

So amb el beneficiari is the correct full form.

Because Catalan nouns have grammatical gender.

In this sentence:

• justificant is masculine → el justificant
• domiciliació is feminine → la domiciliació
• beneficiari is masculine → el beneficiari

This does not always match English logic, because English usually does not mark noun gender this way.

Also, beneficiari has a feminine form:

• el beneficiari = the male beneficiary / the beneficiary
• la beneficiària = the female beneficiary

Yes. The sentence follows a very normal Catalan pattern:

• subject: El justificant
• verb: confirma
• object: la domiciliació bancària
• prepositional phrase: amb el beneficiari

So the structure is straightforward and natural. Catalan can move things around for emphasis, but this version is a standard, neutral order.

The accents help show stress and, in some cases, vowel quality.

• domiciliació is stressed on the final -ó
• bancària is stressed on -à-

So the accents are not optional decoration; they are part of the correct spelling and help you pronounce the words properly.

For a learner, the most useful takeaway is:

• -ció words are often stressed at the end
• -ària words are stressed on the à

Yes, very often.

Even if the meaning is already given to you, it is useful to know that justificant is one of those Catalan words whose best English translation changes with context. It can be:

• receipt
• proof
• supporting document
• voucher
• evidence of payment

So when you see el justificant, think first of the document that serves as proof, and then choose the most natural English word for the situation.
