O corte inclui o trecho.

It depends on context. Corte can mean several things in Portuguese, including:

• cut
• haircut
• cut/edit in audio, video, or text
• sometimes even court in more formal or historical contexts

In O corte inclui o trecho, the most natural reading is something like an edit/cut that includes a certain segment or excerpt. So here corte is probably not a haircut.

Trecho usually means a section, segment, passage, or excerpt.

The best translation depends on context:

• in a text: passage or excerpt
• in audio/video: segment or clip
• in a road/trip context: stretch

So in this sentence, o trecho is the passage/segment/excerpt.

Because Portuguese usually uses definite articles more often than English does.

• o corte = the cut
• o trecho = the excerpt/segment

Both corte and trecho are masculine singular nouns, so they take o.

This is very normal in Portuguese. Even when English might leave out the, Portuguese often keeps the article.

You usually learn the noun together with its article:

• o corte
• o trecho

There is not always a perfect rule, although many nouns ending in -o are masculine. Here:

• corte ends in -e, so the ending does not tell you everything by itself
• trecho ends in -o, which strongly suggests masculine

The safest habit is to memorize nouns with the article, not alone.

Because inclui is the conjugated form, while incluir is the infinitive.

The verb is incluir = to include

In the sentence, the subject is o corte, which is it, so you need the 3rd person singular form:

• eu incluo = I include
• você/ele/ela inclui = you/he/she include(s)

So:

• O corte inclui o trecho = The cut includes the segment

In Brazilian Portuguese, inclui is roughly pronounced like een-kloo-EE.

A few helpful notes:

• the stress is on the last part: -clui
• the ending ui is pronounced as two vowel sounds together
• the initial in- often sounds nasal in natural speech

A rough pronunciation guide for the whole sentence could be:

u KOR-chee een-kloo-EE u TRE-shoo

That is only an approximation, but it can help.

Because this sentence follows a very common Portuguese pattern:

subject + verb + object

• O corte = subject
• inclui = verb
• o trecho = object

So the structure is very straightforward for an English speaker:

• The cut / includes / the segment

Not every Portuguese sentence matches English so neatly, but this one does.

Normally, no, not in standard natural Portuguese for this meaning.

O corte inclui o trecho sounds complete and normal.

Without the articles, Corte inclui trecho, it sounds unnatural in most contexts unless you are reading a headline, making notes, or using a very telegraphic style.

Portuguese generally wants the articles here.

Yes, sometimes. Depending on context, inclui can be translated as:

• includes
• contains
• covers

For example, if you are talking about what is part of a document, edit, package, or selection, English may use different verbs. But includes is the most direct match.

Yes, very often.

In media-related contexts:

• corte can refer to a cut or edit
• trecho can refer to a clip, segment, excerpt, or passage

So this sentence sounds quite natural in discussions about:

• video editing
• film scenes
• audio clips
• selected text passages

That is probably one of the most likely contexts for this sentence.
