Assim que eu encontrar o furo, ponho o remendo.

Assim que means as soon as.

It introduces an action that will happen immediately after another one:

• Assim que eu encontrar o furo, ponho o remendo.
• As soon as I find the hole, I put on the patch / I’ll put on the patch.

In European Portuguese, assim que is a very common way to connect two actions like this.

Because after assim que, when you are talking about a future event, Portuguese normally uses the future subjunctive.

So:

• assim que eu encontrar = as soon as I find
• not assim que eu encontro in this meaning

For many verbs, the future subjunctive form looks the same as the infinitive in some persons, especially:

• eu encontrar
• você/ele/ela encontrar

So even though encontrar looks like an infinitive, here it is functioning as the future subjunctive.

The future subjunctive is a tense/mood Portuguese uses for actions that are still uncertain but expected to happen in the future, especially after words such as:

• quando = when
• se = if
• assim que = as soon as
• logo que = as soon as

In this sentence, the speaker has not found the hole yet. It is a future event, so Portuguese says:

• Assim que eu encontrar o furo...

This is one of the big differences from English. English says:

• As soon as I find it...

Portuguese uses a special form here, not the normal present indicative.

Yes, it could be omitted.

Portuguese often leaves out subject pronouns when the verb already makes the subject clear:

• Assim que encontrar o furo, ponho o remendo.

This is perfectly natural.

The speaker may include eu for one of these reasons:

• emphasis
• clarity
• contrast with someone else
• simply personal style

So both are possible:

• Assim que eu encontrar o furo, ponho o remendo.
• Assim que encontrar o furo, ponho o remendo.

Because Portuguese often uses the present indicative to talk about a future action when the context already makes the future meaning clear.

Here, the first clause already sets up a future situation:

• Assim que eu encontrar o furo...

So the second clause can naturally use the present:

• ponho o remendo

This means something like:

• I’ll put on the patch
• I’m putting on the patch as soon as I find the hole

This is very common in everyday Portuguese.

A more explicitly future version is also possible:

• Assim que eu encontrar o furo, porei o remendo.

But porei sounds more formal or less conversational.

Yes.

• infinitive: pôr = to put
• first person singular present: ponho = I put

This verb is irregular, so the form is not what an English speaker might expect.

Some useful present-tense forms are:

• eu ponho
• tu pões
• ele/ela põe
• nós pomos
• vocês/eles põem

So in the sentence, ponho means I put / I’ll put.

Yes, you could, and it would sound natural.

Both are possible:

• ponho o remendo
• coloco o remendo

Very roughly:

• pôr is the basic verb to put
• colocar can sound a bit more like to place / to put

In many everyday situations, both work. Here, ponho o remendo sounds quite natural and direct.

• furo = hole, puncture, leak, small opening
• remendo = patch, mend, something used to repair a hole or tear

The exact translation depends on context.

For example, o furo could be:

• a hole in a tyre
• a hole in clothing
• a puncture in an inflatable object
• a leak or small damaged spot

And o remendo is the patch used to fix it.

Portuguese uses definite articles more often than English.

So:

• o furo = the hole
• o remendo = the patch

Even when English might sometimes say something more general like find the hole, put on a patch, Portuguese often prefers definite articles if the speaker has a specific hole and a specific patch in mind, or is talking about them as the obvious ones in the situation.

This is very normal in Portuguese.

Grammatically, o remendo is the patch.

But in translation, English may sometimes prefer a patch, depending on the situation.

Portuguese is often more comfortable than English with the definite article when the object is understood from context. So even if Portuguese says o remendo, the most natural English translation in context might sometimes be:

• I’ll put a patch on it

So the Portuguese article does not always map neatly onto English article choice.

The comma separates the introductory subordinate clause from the main clause:

• Assim que eu encontrar o furo, / ponho o remendo.

This is similar to English:

• As soon as I find the hole, I’ll put on the patch.

When the as soon as clause comes first, a comma is very natural.

Yes.

You can also say:

• Ponho o remendo assim que eu encontrar o furo.

This means the same thing.

The original version puts the time condition first, which can sound slightly more natural if the speaker wants to emphasize first finding the hole.

It works in both, but some stylistic preferences may differ.

The grammar of assim que eu encontrar is standard in both European and Brazilian Portuguese.

The choice of ponho is also correct in both. In actual everyday speech, Brazilians might sometimes prefer other patterns depending on context, such as:

• Assim que eu encontrar o furo, eu coloco o remendo.
• Assim que eu encontrar o furo, vou pôr o remendo.

But the original sentence is perfectly understandable and grammatical across varieties.

A careful European Portuguese pronunciation would be roughly:

• Assim que eu encontrar o furo, ponho o remendo.

Some helpful notes:

• assim: the final -im is nasal
• que eu often runs together in speech
• encontrar: the final -r is pronounced, but lightly
• ponho: the nh sounds like the ny in canyon
• remendo: the unstressed vowels are reduced in European Portuguese

A very rough English-style guide could be:

• uh-SEEN keh ew ehn-kon-TRAR oo FOO-roh, PO-nyoo oo rreh-MEN-doo

But actual European Portuguese sounds much more reduced and connected than this guide suggests.

Not always, but very often when the meaning is future.

Compare:

• Assim que eu encontrar o furo, ponho o remendo.
  future meaning → future subjunctive

But if someone is talking about a habitual or repeated action, other structures can appear depending on the context.

For a learner, the safest rule is:

• after assim que, if the action is still in the future, expect the future subjunctive

That rule will serve you well most of the time.

Yes.

• Logo que eu encontrar o furo, ponho o remendo.

This also means as soon as I find the hole, I’ll put on the patch.

Both are correct. Assim que is very common and straightforward. Logo que is also standard, though the preferred choice can vary a bit by speaker and region.

Because the sentence uses the full noun phrase:

• o remendo

If you wanted to replace it with it, then you would use a pronoun:

• Assim que eu encontrar o furo, ponho-o.

However, in real European Portuguese, object pronouns can be a bit tricky because of clitic placement and because speakers often prefer to keep the noun instead of using the pronoun in some contexts.

For a learner, the original version with the full noun is simpler and very natural.

It can be figurative in Portuguese, but in this sentence it is almost certainly literal.

Depending on context, furo can also mean things like:

• a leak
• a puncture
• a scoop in journalism

But with remendo, the physical meaning is the obvious one: a hole or puncture that needs patching.
