Revisamos el directorio de contactos.

Revisamos can be either:

• present: we review / we check
• preterite (simple past): we reviewed / we checked

This happens because for many -ar verbs, the nosotros form is the same in those two tenses.

So only context tells you which one it is:

• Ahora revisamos el directorio de contactos = We’re reviewing the contact directory now
• Ayer revisamos el directorio de contactos = We reviewed the contact directory yesterday

Spanish often leaves out subject pronouns because the verb ending already shows who is doing the action.

• revisamos = we review / we reviewed

So nosotros is not necessary. You could add it for emphasis or contrast:

• Nosotros revisamos el directorio de contactos, no ellos = We reviewed the contact directory, not them

Usually not in this kind of sentence.

Here, revisar means things like:

• to check
• to review
• to look over
• to inspect

For an English speaker, this is important because revise in English often means edit or study again, and Spanish may use other verbs for those ideas, such as:

• repasar = to go over again / review for study
• corregir = to correct
• modificar / editar = to edit / change

So in this sentence, revisamos is more like we checked or we reviewed, not necessarily we revised.

Because Spanish usually uses an article with a specific singular noun.

• el directorio = the directory

In English, article use can be a bit looser in some contexts, but in Spanish, leaving out el here would normally sound incomplete or unnatural.

So:

• Revisamos el directorio de contactos = natural
• Revisamos directorio de contactos = generally not natural in standard Spanish

Because Spanish often connects two nouns with de where English prefers a noun + noun structure.

English:

• contact directory

Spanish:

• directorio de contactos
• literally directory of contacts

This is a very common pattern in Spanish:

• lista de tareas = task list
• tarjeta de crédito = credit card
• centro de salud = health centre

So de is doing normal linking work here.

Because the main thing is one directory, and that directory contains many contacts.

• directorio = singular
• contactos = plural

This is exactly the same logic as in English:

• a contact directory
• a list of names
• a database of clients

The first noun names the item itself; the second noun tells you what it contains.

Yes, definitely.

Depending on context, you might hear:

• directorio de contactos
• lista de contactos
• agenda de contactos

They are similar, but not always identical:

• directorio de contactos often sounds like a directory or organised collection
• lista de contactos is very common for phones, apps, email, etc.
• agenda de contactos can sound like an address book or stored contact book

So directorio de contactos is correct, but lista de contactos may be more common in some everyday tech contexts.

You usually know from context words or the wider situation.

Look for time markers:

• hoy, ahora, normalmente → often present
• ayer, la semana pasada, esta mañana → often past

Examples:

• Hoy revisamos el directorio de contactos = Today we review / are reviewing the contact directory
• Ayer revisamos el directorio de contactos = Yesterday we reviewed the contact directory

Without context, the form is genuinely ambiguous.

A simple approximation for Spain Spanish is:

reh-bee-SAH-mos el dee-rek-TOH-ryoh deh kon-TAK-tos

Main stress:

• reviSAmos
• direcTORio
• conTACtos

A few pronunciation notes:

• v in revisamos is pronounced like a soft Spanish b
• c in contactos sounds like k
• r in directorio is a tapped Spanish r

Yes. It is the most neutral and standard order:

• Verb + object: Revisamos el directorio de contactos

Spanish can change word order for emphasis, but this version is the plain, natural one you would expect in everyday language.

Not by itself in standard grammar.

• revisamos = we review / we reviewed
• revisemos = let’s review or let us review

So if you want a suggestion or proposal, Spanish normally uses the subjunctive form:

• Revisemos el directorio de contactos = Let’s review the contact directory
