Vimos otra posibilidad.

Vimos is the we form of the verb ver (to see).

So:

• ver = to see
• vimos = we saw

Depending on context, ver can also mean things like to notice, to meet with, or to consider, but in a simple sentence like this, we saw is the basic meaning.

It is the preterite tense, first person plural (we).

So vimos means:

• we saw
• we did see

The preterite is used for a completed action in the past.

Because vimos presents the action as a completed event: at some point, we saw another possibility.

By contrast, veíamos is the imperfect, which usually suggests:

• an ongoing past action,
• a repeated action,
• or background description.

Compare:

• Vimos otra posibilidad. = We saw another possibility. / a completed moment
• Veíamos otra posibilidad. = We were seeing another possibility or We used to see another possibility / more ongoing or habitual

Because posibilidad is a feminine noun in Spanish, so the adjective must agree with it.

• posibilidad = feminine singular
• therefore otra = feminine singular form of otro

So:

• otro libro = another book
• otra posibilidad = another possibility

In Spanish, otro/otra usually does not take an indefinite article before it when it means another.

So Spanish says:

• otra posibilidad = another possibility

Not:

• una otra posibilidad ❌

This is different from English, where another historically includes the idea of an + other.

It is built into the verb vimos.

Spanish often leaves out subject pronouns when they are clear from the verb ending.

So:

• Vimos otra posibilidad.
• Nosotros vimos otra posibilidad.

Both are correct, but the version without nosotros is more natural in many contexts.

Yes, possibly.

Although ver literally means to see, in real Spanish it can sometimes be used in a broader sense such as:

• to see
• to realize
• to look at
• to consider

So depending on context, Vimos otra posibilidad could mean:

• We saw another possibility
• We noticed another possibility
• We considered another possibility

But if there is no extra context, we saw another possibility is the safest basic interpretation.

The normal word order is:

• Vimos = verb
• otra posibilidad = direct object

So:

• Vimos otra posibilidad.

Spanish word order is fairly flexible, but this version is the most neutral and natural. You could move things around for emphasis in some contexts, but for a learner, this standard order is the best one to use.

A simple pronunciation guide is:

• Vimos ≈ BEE-mos
• otra ≈ OH-tra
• posibilidad ≈ po-see-bee-lee-THAD in much of Spain

A few useful notes:

• In Spanish, v and b are pronounced very similarly.
• In most of Spain, z and soft c are pronounced with a th sound, but this sentence does not contain those letters.
• In posibilidad, the d at the end is often softer than English d.

Yes, but it does not mean exactly the same thing.

• Vimos otra posibilidad = We saw another possibility
  A finished past event.

• Hemos visto otra posibilidad = We have seen another possibility
  This often connects the past action more strongly to the present.

In Spain, the pretérito perfecto (hemos visto) is commonly used for recent past actions or actions connected to the present, while vimos is a simple completed past event.

It is a noun, and specifically a feminine singular noun.

Breakdown:

• posibilidad = possibility
• singular = one possibility
• feminine = it takes feminine agreement, such as otra

Its plural is:

• posibilidades = possibilities

So:

• otra posibilidad = another possibility
• otras posibilidades = other possibilities
