Cada gasto subvencionable necesita un justificante de gasto.

Because cada is followed by a singular noun in Spanish.

So:

• cada gasto = each expense
• not cada gastos

This is different from English, where each can feel close in meaning to something plural, but in Spanish the noun after cada stays singular.

Examples:

• Cada alumno necesita un libro.
• Cada factura tiene un número.

Because the subject is cada gasto subvencionable, and with cada + singular noun, Spanish normally uses a singular verb.

So:

• Cada gasto subvencionable necesita... = Each eligible expense needs...

Not:

• Cada gasto subvencionable necesitan...

Even though the idea refers to many possible expenses, grammatically Spanish treats cada gasto as singular.

In Spanish, most adjectives usually come after the noun.

So:

• gasto subvencionable = eligible/subsidisable expense

This is the normal position for a descriptive or classifying adjective, especially in formal or administrative language.

Compare:

• un proyecto interesante
• una ayuda económica
• un gasto subvencionable

Putting subvencionable before the noun would sound unusual here.

No, they are not the same.

• subvencionable = eligible for a subsidy / capable of being subsidised
• subvencionado = subsidised / already receiving a subsidy

So in this sentence, gasto subvencionable means an expense that qualifies for funding or support, not necessarily one that has already been paid back or approved.

This distinction is very common in official Spanish.

Yes, here justificante is masculine: un justificante.

Even though it ends in -ante, that ending does not automatically make a noun feminine. Many nouns ending in -ante are masculine or can vary depending on the word.

In administrative Spanish, justificante usually means:

• proof
• supporting document
• receipt
• evidence of payment or expense

So:

• un justificante de gasto = a document proving the expense

It is a very common administrative expression meaning a document that proves an expense exists and is valid.

Depending on context, it could be:

• a receipt
• an invoice
• a proof of payment
• another supporting document

It is broader than just receipt in everyday English. In bureaucracy, justificante often means any official document used to justify or support a claim.

Because the two uses of gasto are doing different jobs:

• gasto subvencionable = the expense itself
• justificante de gasto = the document that proves that expense

So the repetition is normal and natural in formal Spanish. It may feel repetitive in English, but in Spanish administrative writing this kind of repetition is very common.

It helps make the meaning precise.

Yes, it could, but the meaning or tone changes slightly.

• necesita un justificante de gasto = it needs a supporting expense document
• necesita justificante de gasto = it needs supporting expense documentation

Without the article, it sounds a bit more general or institutional. With un, it points more clearly to an individual document.

In formal instructions, both can appear, but un justificante de gasto is very natural.

Because Spanish often uses noun + de + noun to show the relationship between two nouns.

So:

• justificante de gasto = proof/document of expense
• factura de compra = purchase invoice
• centro de salud = health centre

Here de gasto tells us what kind of justificante it is: one related to an expense.

Yes, very formal and administrative.

Words like:

• subvencionable
• justificante
• gasto

are especially common in:

• grant applications
• reimbursement rules
• government forms
• funding guidelines
• accounting documents

In everyday conversation, a Spanish speaker might choose more ordinary wording depending on the context.

Usually expense is better here than cost.

In this kind of administrative or accounting context:

• gasto = expense
• coste/costo = cost

A gasto is often something actually incurred or claimed. That is why expense fits better in this sentence.

So:

• Cada gasto subvencionable... = Each eligible expense...

Not exactly.

• cada gasto = each expense
• todos los gastos = all the expenses

Both can refer to a whole set, but cada looks at the items one by one, while todos los looks at them as a group.

That is why cada fits very well with rules and requirements:

• Cada gasto subvencionable necesita...
  = for every individual eligible expense, this requirement applies.

Possibly, but subvencionable is more specific and more typical in funding or grant language in Spain.

• elegible = eligible
• subvencionable = eligible to be subsidised / fundable

In many official contexts, subvencionable is the preferred word because it directly refers to the idea of a subsidy or grant.

So gasto subvencionable is the standard expression in many administrative texts.

No.

• factura = invoice
• justificante = supporting document / proof

A factura can be a type of justificante, but justificante is a wider term.

For example, a justificante might be:

• a factura
• a receipt
• a bank payment confirmation
• another accepted proof document

So Spanish uses justificante when the exact kind of proof may vary.

Yes. It is very typical of official Spanish because it is:

• concise
• impersonal in tone
• precise
• noun-heavy

Administrative Spanish often prefers compact structures like:

• Cada solicitud debe incluir...
• Cada beneficiario presentará...
• Cada gasto subvencionable necesita...

This style can sound a bit dense to learners, but it is very common in forms, regulations, and public administration.
