Intentamos adivinar la respuesta.

Intentamos is the 1st person plural form of intentar — so it means we try or, depending on context, we tried.

That is because intentar is a regular -ar verb:

• yo intento
• tú intentas
• él/ella intenta
• nosotros/nosotras intentamos
• vosotros/vosotras intentáis
• ellos/ellas intentan

A useful thing to know: intentamos can be both:

• present: we try / we are trying
• preterite: we tried

So the exact meaning depends on context.

Spanish often omits subject pronouns because the verb ending already shows who the subject is.

Here, intentamos already tells you the subject is we, so nosotros is not necessary.

You could say:

• Nosotros intentamos adivinar la respuesta.

But it usually sounds more natural to leave nosotros out unless you want to:

• emphasize we
• contrast with someone else
• avoid confusion

Because intentar is normally followed directly by an infinitive.

So the pattern is:

• intentar + infinitive

Examples:

• Intento dormir. = I try to sleep.
• Intentamos adivinar. = We try to guess.

You do not normally say:

• intentar de + infinitive
• intentar a + infinitive

A similar verb that does often use a preposition is tratar de:

• Tratamos de adivinar la respuesta.

That also means We try to guess the answer.

Because after intentamos, Spanish uses the infinitive of the second verb.

This is very similar to English to + verb:

• Intentamos adivinar
• We try to guess

In Spanish, after many verbs like querer, poder, necesitar, preferir, and intentar, the next verb stays in the infinitive:

• Quiero comer.
• Podemos salir.
• Necesitan estudiar.
• Intentamos adivinar.

Here adivinar means to guess.

It can also have related meanings depending on context, such as:

• to figure out
• to predict
• to tell by intuition

But in this sentence, the most natural meaning is to guess.

For example:

• Adivina mi edad. = Guess my age.
• No puedo adivinar la respuesta. = I can’t guess the answer.

Because respuesta is a noun, and here it needs an article: la.

La respuesta means the answer.

Spanish often uses articles in places where English also uses them, and sometimes even where English would leave them out. In this sentence, the speaker is referring to a specific answer, so la is natural.

Compare:

• adivinar la respuesta = guess the answer
• adivinar una respuesta = guess an answer

The second one would sound less natural if there is one particular correct answer being talked about.

Yes, the normal word order here is very natural:

• Intentamos adivinar la respuesta.

This follows a common pattern:

• verb + infinitive + object

You could change the order in some contexts, but the original sentence is the most neutral and standard.

For example, you might hear:

• La respuesta intentamos adivinarla.

But that is much less neutral and would usually need a special context for emphasis. For a learner, the original word order is the best one to use.

Yes. Intentamos is one of those forms that can mean either:

• we try / we are trying (present)
• we tried (preterite)

Spanish has a few forms like this where the nosotros form looks the same in both tenses.

So without more context, the sentence is ambiguous.

For example:

• Cada vez que jugamos, intentamos adivinar la respuesta.
  = Every time we play, we try to guess the answer.

• Ayer intentamos adivinar la respuesta, pero no pudimos.
  = Yesterday we tried to guess the answer, but we couldn’t.

In the sentence itself, vosotros does not appear, because the subject is we.

But if you are learning Spanish from Spain, it is useful to notice that Spain commonly uses vosotros for you all in informal situations.

For example, if you changed the subject from we to you all, you would get:

• Intentáis adivinar la respuesta. = You all try to guess the answer.

So:

• intentamos = we try
• intentáis = you all try in Spain

Yes. Tratamos de adivinar la respuesta is also correct and natural.

Both mean roughly We try to guess the answer, but the structures are different:

• intentar + infinitive
• tratar de + infinitive

So:

• Intentamos adivinar la respuesta.
• Tratamos de adivinar la respuesta.

Both are good Spanish.

No. Intentamos has no written accent mark.

It follows the normal stress rules of Spanish, so the stress naturally falls on ta:

• in-ten-TA-mos

That is why no accent mark is needed.

This is true whether it is present or preterite; the spelling stays the same.
