Aluno is the masculine form, and aluna is the feminine form.
So:
Notice that inteligente stays the same in both masculine and feminine singular. That is very common with adjectives ending in -e.
In Portuguese, adjectives often come after the noun, unlike in English.
So:
This is the most natural order here.
You can sometimes move adjectives before the noun in Portuguese, but that often changes the tone or emphasis. For a straightforward description, o aluno inteligente is the normal choice.
Because inteligente is an adjective with the same form for masculine and feminine singular.
Compare:
Only the article and noun change. The adjective stays the same.
In the plural, it becomes:
So the singular form is inteligente, and the plural form is inteligentes.
It comes from fazer, which is an irregular verb.
Some common forms are:
So fez is the he/she/you-formal preterite of fazer.
Molde can mean several related things depending on context, such as:
So in different situations it could refer to something used in:
Even if the meaning has already been given to you, it is useful to know that molde is a fairly flexible word and does not always refer to just one exact object.
In European Portuguese, fez is pronounced roughly like fezh or fesh, depending on the speaker and region.
A useful approximation is:
That final z often sounds like sh in European Portuguese when it comes at the end of a word.
So the full sentence sounds approximately like:
This is only an approximation for English speakers, but it helps you notice some typical European Portuguese pronunciation patterns.
Yes, Portuguese often allows the subject to be omitted if it is understood from context.
So:
However, in your full sentence, o aluno inteligente is included because the speaker wants to identify exactly who did it.
Portuguese does this a lot because the verb form often gives information about the subject. In this case, fez could mean he/she/you-formal did, so context is still important.
The normal order is:
So the basic structure is:
Subject + Verb + Object
More precisely, inside the subject phrase you get:
That makes the whole sentence very typical and natural Portuguese word order.
