Revisamos el plan familiar de emergencia.

In Spanish, the subject pronoun is often omitted because the verb ending already tells you who is doing the action.

• revisamos = we review / we reviewed
• The ending -amos shows we.

So (Nosotros) revisamos el plan familiar de emergencia is grammatical, but Spanish usually drops nosotros unless it is needed for emphasis or clarity.

Revisamos can be understood in two different ways, depending on context:

• present tense: we review
• preterite: we reviewed

This happens because some -ar verbs have the same form for:

• nosotros in the present
• nosotros in the preterite

So only context tells you which meaning is intended. Since you said the meaning is already shown to the learner, that context would decide it.

The infinitive is revisar.

It usually means things like:

• to review
• to check
• to go over
• to inspect

In this sentence, it suggests looking over the emergency family plan to make sure it is correct, updated, or understood.

El plan means the plan. Spanish often uses the definite article when the thing is already known from the context.

So:

• el plan = the plan
• un plan = a plan
• nuestro plan = our plan

If the speaker means a specific family emergency plan that everyone already knows about, el plan is natural.

Also, Spanish sometimes uses the where English might prefer our, especially when the ownership is obvious from the situation. Still, nuestro plan familiar de emergencia would also be possible if the speaker wanted to stress that it is our plan.

In Spanish, adjectives usually come after the noun.

So:

• plan familiar = family plan

Here, familiar means related to the family / household, not familiar in the English sense of well-known.

That is an important false friend:

• English familiar = well-known
• Spanish familiar = family-related

Spanish often uses de + noun to describe the type or purpose of something.

So:

• plan de emergencia = emergency plan
• literally: plan of emergency

This is very common in Spanish. A few similar examples are:

• salida de emergencia = emergency exit
• botiquín de primeros auxilios = first-aid kit
• centro de salud = health centre

So plan familiar de emergencia means a family emergency plan.

You can break it down like this:

• el plan = the plan
• familiar = family / household-related
• de emergencia = for emergencies / emergency

So the full phrase means:

• the family emergency plan
• or more literally, the family plan for emergencies

A helpful way to read it is: [el plan] [familiar] [de emergencia]

It is a very natural phrase, especially in safety or preparedness contexts, but it is not so fixed that it cannot vary.

You might also see:

• plan familiar de emergencias
• plan de emergencia familiar
• plan de emergencia de la familia

All of these can be understandable, though plan familiar de emergencia sounds natural and clear.

Sometimes, but the nuance changes.

• revisamos usually means we check / review / inspect
• repasamos usually means we go over again / review for study or practice

So if the idea is checking whether the family emergency plan is up to date or correct, revisamos is better.

If the idea is reading through it again to remember it, repasamos could work in some contexts.

In standard Peninsular Spanish, it is pronounced approximately:

reh-bee-SAH-mos

A few details:

• r in revisamos is a soft tapped r
• v in Spanish sounds very close to b
• the stress is on sa: re-vi-SA-mos

So the stress pattern is straightforward because it ends in -s, and words like this normally stress the second-to-last syllable.

Because familiar is an adjective, not a noun phrase.

Compare:

• plan familiar = family plan
• plan de emergencia = emergency plan
• plan de la familia = the family’s plan / the plan of the family

So Spanish uses two different structures here:

1. noun + adjective

   • plan familiar

2. noun + de + noun

   • plan de emergencia

That mix is completely normal in Spanish.
