El resultado puede variar.

El is the definite article, meaning the.

Spanish often uses articles more regularly than English does, so el resultado is the normal way to say the result. In many contexts, dropping the article would sound incomplete or unnatural.

Also, resultado is a masculine singular noun, so it takes el, not la.

You usually learn the gender together with the noun: el resultado.

In this case, resultado ends in -o, which is very often masculine in Spanish, though there are exceptions in the language as a whole. Here, the article el confirms it.

So:

• el resultado = masculine singular
• los resultados = masculine plural

Here, resultado is a noun meaning result or outcome.

It is not the past participle of resultar in this sentence. Even though resultado can look like a participle form, in El resultado puede variar, it clearly functions as a noun: it is the subject of the sentence.

Because the subject is el resultado, which is third person singular.

The verb poder means to be able to, can, or sometimes may/might, depending on context.

Present tense of poder:

• yo puedo
• tú puedes
• él/ella/usted puede
• nosotros podemos
• vosotros podéis
• ellos/ellas/ustedes pueden

Since el resultado = it / the result, the correct form is puede.

Poder is a stem-changing verb in the present tense. Its o changes to ue in most forms.

So:

• poder
• yo puedo
• tú puedes
• él/ella puede

But:

• nosotros podemos
• vosotros podéis

This kind of change is very common in Spanish verbs.

Puede variar literally means can vary.

Depending on context, English might translate it as:

• can vary
• may vary
• might vary

In warnings, labels, and formal statements, puede variar is very often best understood as may vary.

Grammatically:

• puede = modal verb
• variar = infinitive

This is the same structure as:

• Puede cambiar = It can/may change
• Puede ocurrir = It can/may happen

Because after a conjugated modal verb like poder, the next verb normally stays in the infinitive.

So:

• puede variar = can vary
• puede cambiar = can change
• puede pasar = can happen

This works much like English:

• it can vary not
• it can varies

Yes, but it means something slightly different.

• El resultado puede variar = The result can/may vary
• El resultado varía = The result varies / is varying

The first expresses possibility. The second expresses a more direct fact or general statement.

So if you want to say that variation is possible, puede variar is the better choice.

This is the most neutral and natural word order in Spanish:

subject + verb + infinitive

• El resultado = subject
• puede = conjugated verb
• variar = infinitive

You could also hear Puede variar el resultado, but that changes the emphasis and is less neutral. For a simple statement, El resultado puede variar is the standard order.

They are similar, but not always identical.

• variar = to vary, to differ, to fluctuate
• cambiar = to change

In this sentence, variar suggests that the result may be different depending on conditions. It sounds very natural in formal or technical contexts.

For example:

• El precio puede variar. = The price may vary.
• El horario puede cambiar. = The schedule may change.

Sometimes both work, but variar often sounds a bit more like not always being the same rather than changing from one state to another.

A simple pronunciation guide is:

el reh-sool-TAH-doh PWEH-deh bah-ree-AR

A few points:

• resultado is stressed on ta: re-sul-TA-do
• puede is stressed on pue
• variar is stressed on the last syllable: va-ri-AR
• In Spain, v and b are pronounced very similarly, so variar begins with a sound close to b

A more IPA-style pronunciation would be approximately:

[el resulˈtaðo ˈpweðe βaˈɾjaɾ]

Usually it refers to a result that is understood from the context: the result of something already being discussed.

For example:

• a test
• a treatment
• a calculation
• a process

In notices and general statements, Spanish often still uses the definite article where English might also use the or sometimes be more flexible.

So El resultado puede variar most naturally means The result may vary, referring to the relevant result in context.
