Esta prueba confirma el resultado.

Because prueba is a feminine singular noun, and the demonstrative esta must agree with it.

• este = this, for masculine singular nouns
• esta = this, for feminine singular nouns

Examples:

• este libro = this book
• esta prueba = this test / this proof

So the form changes to match the noun’s gender.

Prueba can mean several things depending on context, including:

• test
• proof
• trial
• experiment

In this sentence, it could mean either test or proof, depending on the broader context. Spanish often allows this kind of ambiguity where English would choose one more specifically.

For example:

• In a scientific context, prueba might be test
• In an argument or legal context, it might be proof/evidence

Confirma is the third person singular form of the verb confirmar in the present tense.

The subject is esta prueba, which is singular, so the verb must also be singular:

• yo confirmo = I confirm
• tú confirmas = you confirm
• él / ella / usted confirma = he / she / you confirm
• esta prueba confirma = this test/proof confirms

So confirma matches the subject esta prueba.

Spanish often omits subject pronouns because the verb ending already gives enough information.

So instead of saying:

• Esta prueba confirma el resultado

you could technically say:

• Ella confirma el resultado

if ella referred back to la prueba, but that would usually sound unnecessary here.

Spanish prefers the noun itself or no pronoun when the meaning is already clear.

Spanish uses the definite article much more often than English does.

So el resultado means the result, and including el sounds natural and complete in Spanish.

In many cases, leaving out the article would sound unnatural or would slightly change the meaning. Here, el resultado is the normal way to say it.

Nouns in Spanish have grammatical gender, and resultado is a masculine noun.

That is why it takes:

• el resultado
• not la resultado

A useful pattern is that many nouns ending in -o are masculine, though this is not an absolute rule.

Because here esta is a demonstrative adjective meaning this, and demonstratives normally do not take an accent in modern Spanish spelling.

So:

• esta prueba = this test/proof

Older materials may sometimes show accent marks on demonstratives when they were used as pronouns, such as éste, but current standard Spanish generally writes them without accents except in very unusual cases of ambiguity.

Yes, Spanish word order is flexible, but Esta prueba confirma el resultado is the most neutral and natural order.

It follows the common pattern:

• subject + verb + object

Changing the order is possible, but it usually adds emphasis or sounds more literary or marked.

For example:

• El resultado lo confirma esta prueba = This test/proof confirms the result, with more emphasis on the result

So for a learner, the original order is the safest and most standard.

It usually means result, but in context it can refer to things like:

• the result of a test
• the outcome of an experiment
• the conclusion of a process
• sometimes even a score or outcome in a broader sense

So the exact English translation depends on context, but result/outcome is the core idea.

A natural Spain Spanish pronunciation would be approximately:

EH-sta PRWE-ba kon-FEER-ma el reh-sool-TA-do

A few helpful notes:

• prueba contains the diphthong ue, so it sounds roughly like PRWE-ba
• c in confirma is a normal hard k sound because it comes before o
• r in resultado is a light tapped r
• In much of Spain, the d in resultado may sound softer between vowels

A rough IPA version is:

[ˈes.ta ˈpɾwe.βa koɱˈfiɾ.ma el re.sulˈta.ðo]

You could, but it would usually mean something slightly different.

• Esta prueba confirma el resultado = This test/proof confirms the result
• Esta prueba está confirmando el resultado = This test/proof is confirming the result

Spanish uses the simple present much more often than English does, so confirma is the normal choice here unless you specifically want to stress an ongoing process.

You would change all the words that need to agree:

• Esta prueba confirma el resultado.
• Estas pruebas confirman el resultado.

Changes:

• esta → estas
• prueba → pruebas
• confirma → confirman

If the object were also plural, then:

• Estas pruebas confirman los resultados. = These tests/proofs confirm the results.
