Eu corto o pepino às rodelas para a salada.

You can omit Eu very often in Portuguese.

Because corto already shows I cut, the subject is clear from the verb ending. So both are correct:

• Eu corto o pepino às rodelas para a salada.
• Corto o pepino às rodelas para a salada.

Including Eu can add emphasis, contrast, or clarity, for example if you want to stress that I do it.

Corto is the 1st person singular present indicative of cortar.

So:

• eu corto = I cut
• tu cortas = you cut
• ele/ela corta = he/she cuts

In this sentence, corto can mean:

• something you do regularly
• something you are doing now
• a general statement about how you prepare it

The present tense in Portuguese often covers all of these, depending on context.

Portuguese uses definite articles more often than English.

So where English might say I cut cucumber, Portuguese usually prefers corto o pepino if you mean a specific cucumber you are working with.

Compare:

• o pepino = the cucumber / the cucumber in question
• um pepino = a cucumber

Leaving out the article here would usually sound unnatural.

Às rodelas is an idiomatic way to say into round slices or in rounds.

The noun rodela means something like a round slice, disc, or ring-shaped piece. In cooking, às rodelas is very common for things cut into round slices, such as cucumber, carrot, or onion.

So the phrase describes how the cucumber is cut.

Às is a contraction of:

• a
  • as = às

This is very common in Portuguese.

Here, as is the feminine plural article before rodelas, and the grave accent marks the contraction. It is not the same kind of accent as in stress marks like é or ó.

Other similar contractions are:

• ao = a + o
• à = a + a
• aos = a + os
• às = a + as

Because rodelas does not describe the cucumber as an adjective. It names the pieces you get after cutting it.

So the idea is:

• one cucumber
• cut into many round slices

That is why pepino stays singular, but rodelas is plural.

Yes. Em rodelas is also very common and natural.

So these are both possible:

• Corto o pepino às rodelas.
• Corto o pepino em rodelas.

They are very close in meaning. In everyday usage, both are widely understood. Às rodelas feels like a very established cooking expression, and em rodelas is also straightforward and common.

It shows purpose.

So para a salada means the cucumber is being cut for the salad or to use in the salad.

Here, para does not mean movement in the sense of physically going somewhere. It means for in the sense of intended use.

The article a in a salada suggests a specific salad, probably the one being prepared.

No. The present tense here can have more than one reading.

Depending on context, Eu corto o pepino às rodelas para a salada could mean:

• I cut the cucumber into slices for the salad right now
• I usually cut the cucumber into slices for the salad
• This is how I cut the cucumber for the salad

Portuguese often relies on context rather than changing the tense.

The given word order is very natural and standard:

• Eu corto o pepino às rodelas para a salada.

But Portuguese allows some movement, especially for emphasis. For example:

• Para a salada, corto o pepino às rodelas.

That puts extra focus on for the salad.

Still, the original order is probably the most neutral and natural for a learner to use.

It is correct, but European Portuguese often drops subject pronouns unless they are needed.

So in many everyday situations, a native speaker might simply say:

• Corto o pepino às rodelas para a salada.

Using Eu is not wrong at all. It just sounds slightly more explicit. Learners often use subject pronouns more often than native speakers do, which is normal.

Yes, a few:

• corto: the final -o is usually reduced, sounding closer to u than to a full English oh
• pepino: the first e is reduced in European Portuguese
• às: this is stressed because it is a single important word
• salada: the unstressed vowels are reduced compared with many Brazilian pronunciations

A rough learner-friendly approximation would be something like:

• Eu corto o pepino às rodelas para a salada
• eu KOR-tu u puh-PEE-nu ash ru-DEH-lash PA-ra a sa-LA-da

That is only an approximation, but it helps show the vowel reduction that is typical of European Portuguese.
