Por poco revocamos el testamento.

Por poco means almost, very nearly, or by a narrow margin. It introduces something that came close to happening but, in the end, did not happen.

So Por poco revocamos el testamento means that revoking the will was close to happening, but it ultimately did not happen.

Very often, yes. In many contexts, por poco and casi are close in meaning:

• Por poco revocamos el testamento
• Casi revocamos el testamento

Both mean we almost revoked the will.

A useful nuance is that por poco can sound a bit more dramatic or like a near miss, while casi is the more neutral, everyday word for almost.

This is a very common question because revocamos has the same form in two tenses:

• present indicative: we revoke
• preterite: we revoked

So by itself, revocamos is ambiguous.

In this sentence, context is what tells you the meaning. With por poco, the sentence is normally understood as a near event in the past:

• we almost revoked the will

So even though the form is ambiguous, the whole sentence strongly points to a past meaning.

Because the idea did not happen is already built into por poco.

Spanish often says:

• Por poco + verb

to mean almost did X, but didn’t.

So:

• Por poco revocamos el testamento

already contains the idea that the revocation never actually happened.

Learners sometimes expect something like Por poco no revocamos..., but for a beginner/intermediate learner, the safest pattern is:

• por poco + affirmative verb

That is the clearest standard way to say almost.

No. Here it takes the indicative, not the subjunctive.

That is why you see:

• revocamos

and not a subjunctive form.

This makes sense because the sentence refers to a real situation that nearly happened, not to a wish, doubt, command, or hypothetical idea.

Revocar is correct, but it sounds fairly formal and often legal/administrative.

It is the kind of verb you expect with things like:

• laws
• permissions
• decisions
• legal documents

So revocar el testamento sounds legal and precise: to revoke the will.

In more everyday conversation, people might sometimes choose a less formal expression depending on the situation, but revocar is absolutely appropriate here.

Because el testamento refers to a specific will, one that is already known or understood from the context.

• el testamento = the will
• un testamento = a will

Using el suggests there is a particular will being discussed, not just any will in general.

Yes, if it is already clear what is being referred to.

You could say:

• Por poco lo revocamos.

That means We almost revoked it.

This is very natural in Spanish once the noun has already been mentioned. Spanish often avoids repeating nouns when the object is already clear from context.
