Queremos observar el águila.

Queremos is the present tense, first-person plural form of querer.

• querer = to want
• queremos = we want

So Queremos observar el águila literally has we want as its main verb.

A useful pattern is:

• quiero = I want
• quieres = you want
• quiere = he/she/it wants
• queremos = we want
• queréis = you all want (used in Spain)
• quieren = they/you all want

One important detail: querer is a stem-changing verb in most forms (quiero, quieres, quiere...), but not in nosotros and vosotros, so it stays queremos, not quierimos.

Because after querer, Spanish normally uses an infinitive.

So the structure is:

• queremos + infinitive
• we want + to + verb

Examples:

• Queremos observar = we want to observe
• Quiero comer = I want to eat
• Quieren salir = they want to leave

If you said observamos, that would mean we observe or we are observing, which would create a different sentence:

• Queremos observar el águila = We want to observe the eagle
• Observamos el águila = We observe / are observing the eagle

In Spanish, after verbs like querer, you usually go straight to the infinitive, without a separate word equivalent to English to.

English:

• We want to observe

Spanish:

• Queremos observar

So observar already means to observe as an infinitive, but Spanish does not need an extra word between queremos and observar.

This is very common:

• Quiero aprender = I want to learn
• Necesitamos estudiar = We need to study
• Prefieren esperar = They prefer to wait

This is a very common question, and the answer is important.

Águila is grammatically feminine, but in the singular it takes el instead of la because it begins with a stressed a sound.

So you say:

• el águila
• el agua
• el arma

This is done mainly for pronunciation and sound flow. Spanish avoids la águila, because the two adjacent a sounds sound awkward.

But the noun is still feminine. You can see that with adjectives:

• el águila blanca = the white eagle
  (blanca, not blanco)

And in the plural, the normal feminine article returns:

• las águilas

So:

• singular: el águila
• plural: las águilas

You can tell from agreement with adjectives or other words that modify it.

For example:

• el águila blanca = the white eagle
• el águila herida = the injured eagle

The adjectives are feminine:

• blanca
• herida

That shows that águila is still a feminine noun, even though it uses el in the singular.

So think of el here as a special article choice for sound reasons, not as proof that the noun is masculine.

The accent mark in águila shows where the stress goes: Á-gui-la.

Without getting too technical, Spanish spelling rules would normally make a word like aguila stressed on gui, but the real pronunciation stresses the first syllable, so the written accent is needed:

• águila = stress on Á

This matters because the rule about using el with feminine nouns applies when the noun starts with a stressed a sound. In águila, that stressed first a is exactly why you get el águila.

Spanish often leaves out subject pronouns because the verb ending already tells you who the subject is.

Here:

• queremos clearly means we want

So nosotros is not necessary.

You could say:

• Nosotros queremos observar el águila

But that usually sounds more emphatic, as if you want to stress we:

• We want to observe the eagle

In normal speech, Spanish usually prefers:

• Queremos observar el águila

This is about the personal a.

Spanish uses a before a direct object mainly when that object is a specific person, and sometimes with pets or personified animals.

Examples:

• Veo a María = I see María
• Conozco a tu hermano = I know your brother

But with a general animal reference, especially in a neutral sentence like this, Spanish normally does not use a:

• Queremos observar el águila

If the animal were very specific, familiar, or personified, some speakers might use a in other contexts, but here its absence is completely normal.

In Spain, queremos is pronounced roughly like:

• keh-REH-mohs

A few pronunciation notes:

• qu before e sounds like a hard k
• the e vowels are pure Spanish e sounds, not like the many shifting English vowel sounds
• the r in queremos is a light tapped r, not a heavy English r
• the final s is clearly pronounced in standard Peninsular Spanish

So try something like:

• keh-REH-mohs

A simple approximation is:

• keh-REH-mohs ob-ser-BAHR el AH-gee-lah

A few details:

• queremos → keh-REH-mohs
• observar → ob-ser-BAHR
• el águila → el AH-gee-lah

More natural rhythm:

• Queremos observar el águila.
• keh-REH-mohs ob-ser-BAHR el AH-gee-lah

In careful pronunciation, the g in águila is a hard g because it comes before u. The gui sounds roughly like gee.

Possibly, but the meaning changes a bit.

• ver = to see
• mirar = to look at / watch
• observar = to observe

Observar sounds a bit more deliberate, careful, or attentive than ver, and often more formal or precise than mirar.

Compare:

• Queremos ver el águila = We want to see the eagle
• Queremos mirar el águila = We want to look at the eagle
• Queremos observar el águila = We want to observe the eagle

So observar suggests more focused attention, maybe like birdwatching, studying, or examining it carefully.

Not in this form.

First, a el would normally contract to al:

• a el → al

So if a were needed, it would be:

• Queremos observar al águila

But in this sentence, that is usually not the neutral default. Since águila here is just the direct object and not treated as a person-like being, Spanish normally says:

• Queremos observar el águila

So the standard version is the one you were given.
