Evacuamos por la ruta de evacuación.

Evacuamos is the 1st person plural form of evacuar, so it means we evacuate or we evacuated, depending on context.

In Spanish, this form is the same in:

• the present tense: we evacuate / we are evacuating
• the preterite: we evacuated

So by itself, Evacuamos por la ruta de evacuación can be understood as either:

• We evacuate via the evacuation route, or
• We evacuated via the evacuation route

Usually the surrounding context makes the time clear.

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

Here, -amos tells you the subject is nosotros/nosotras = we.

So:

• Evacuamos por la ruta de evacuación = normal, natural Spanish
• Nosotros evacuamos por la ruta de evacuación = also possible, but more emphatic

You would add nosotros only if you want contrast or emphasis, for example:

• Nosotros evacuamos por la ruta de evacuación, no por la entrada principal.

Here por means through, along, or by way of a route.

So por la ruta de evacuación means:

• via the evacuation route
• through the evacuation route
• along the evacuation route

Spanish commonly uses por for movement through a place or along a path:

• Entramos por la puerta trasera = We entered through the back door.
• Paseamos por el parque = We walked through the park.

Para would not fit here, because para usually expresses:

• destination
• purpose
• deadline
• recipient

So por is the natural choice with a route.

Ruta de evacuación literally means route of evacuation.

In Spanish, de is very often used where English uses a noun as an adjective:

• plan de emergencia = emergency plan
• salida de emergencia = emergency exit
• ruta de evacuación = evacuation route

So de evacuación describes what kind of route it is.

This is a very common Spanish structure:

• centro de salud
• mesa de comedor
• tarjeta de crédito

Spanish often uses the definite article more than English does.

So la ruta de evacuación sounds natural when referring to the known or designated evacuation route.

Compare:

• Evacuamos por la ruta de evacuación. = We evacuated via the evacuation route.
• Evacuamos por una ruta de evacuación. = We evacuated via an evacuation route.
  This sounds less specific.

If there is a particular official route being referred to, la is the expected article.

Yes, evacuar is correct and natural, especially in:

• safety instructions
• emergency procedures
• official or formal contexts

That said, in everyday speech people might also use verbs like:

• salir = to leave / go out
• desalojar = to evacuate / clear out (often more transitive or official)

Examples:

• Salimos por la ruta de evacuación. = We went out via the evacuation route.
• Evacuamos el edificio. = We evacuated the building.
• Desalojamos el edificio. = We cleared/evacuated the building.

So evacuamos is fine, but it sounds slightly more formal or procedural than salimos.

Here it is being used intransitively.

That means there is no direct object after the verb. The sentence does not say what was evacuated; it only says how or by which route the evacuation happened.

Compare:

• Evacuamos por la ruta de evacuación.
  Here, we evacuated / left via the evacuation route.

• Evacuamos el edificio.
  Here, the building is the direct object: we evacuated the building.

So evacuar can be used both ways depending on the context.

No. For let’s evacuate, Spanish would normally use:

• Evacuemos por la ruta de evacuación.

That form, evacuemos, is the 1st person plural command/subjunctive.

So:

• Evacuamos = we evacuate / we evacuated
• Evacuemos = let’s evacuate

This is an important distinction.

Spanish usually prefers the noun + de + noun pattern for this kind of idea.

So ruta de evacuación is the standard, natural phrase.

A more adjective-like form such as evacuatoria exists in some technical or formal language, but it is much less common here and would sound more specialized or unnatural to many learners in everyday use.

For normal Spanish, especially the kind you are likely to see in signs, safety rules, or basic instruction:

• ruta de evacuación is the phrase to learn

In Spain, a careful pronunciation would be roughly:

• e-va-KWA-mos

A few useful points:

• The stress is on -a- in -kwa-: evaCUAmos
• cu here sounds like kw
• The letter v in Spanish is usually pronounced very similarly to b, not like the English v
• The final s is clearly pronounced in most of Spain

So a learner-friendly approximation is:

• eh-bah-KWAH-mos

Sometimes, but they are not always interchangeable.

• ruta de evacuación = evacuation route
• camino de evacuación = evacuation path/way
• salida de emergencia = emergency exit

A very common fixed phrase is actually:

• salida de emergencia, not salida de evacuación

So if you are talking about:

• the whole path people follow: ruta de evacuación
• a specific door/exit: salida de emergencia

That distinction is useful in real-life Spanish.

Yes, but the original order is the most neutral and natural.

Standard order:

• Evacuamos por la ruta de evacuación.

You could move things around for emphasis, for example:

• Por la ruta de evacuación evacuamos.

But that sounds marked or literary, not the normal everyday choice.

So for most learners, the best pattern is:

• verb + por + route

That is the clearest and most natural version.
