A administradora preparou o relatório.

Here, A means the.

So A administradora = the administrator / the female administrator.

It is not the pronoun she. In Portuguese, she is ela. Since A comes directly before a noun, it is the feminine singular definite article.

Administradora is the feminine form, used for a woman.

• administrador = male administrator
• administradora = female administrator

The article also matches:

• o administrador = the male administrator
• a administradora = the female administrator

Portuguese nouns and articles often show grammatical gender this way.

Preparou is the preterite (simple past) of preparar.

It means prepared.

In this sentence, it is third person singular, so it can mean:

• he prepared
• she prepared
• you prepared (formal você)

Here it matches a administradora, so the meaning is the administrator prepared.

Because Portuguese often does not need a subject pronoun when the subject is already clear.

In this sentence, the subject is explicitly stated as A administradora, so adding ela would be unnecessary.

Portuguese commonly uses either:

• the noun itself: A administradora preparou o relatório.
• or a pronoun if the subject is already known: Ela preparou o relatório.

O relatório means the report.

Portuguese often uses definite articles where English also uses them, especially when referring to a specific thing. Here, it is a particular report, so o relatório is natural.

If you said just relatório, it would sound less complete in this sentence. In standard neutral Portuguese, preparou o relatório is the expected form for prepared the report.

Because relatório is a masculine singular noun.

So the article must also be masculine singular:

• o relatório = the report
• um relatório = a report

This shows agreement between the noun and its article, just like:

• a administradora
• o relatório

The accent marks the stressed syllable.

So relatório is stressed on tó:

• re-la-TÓ-rio

Without the accent, a learner might guess the stress incorrectly. In Portuguese, written accents are very helpful because they show where the word is emphasized and sometimes also indicate vowel quality.

A simple pronunciation guide is:

a administRAdo-ra prepaROU u relaTÓriu

A few useful notes:

• preparou ends with a sound similar to ow
• unstressed o often sounds like u in Brazilian Portuguese, so o relatório can sound like u relatório
• relatório is stressed on tó

A more natural Brazilian pronunciation is approximately:

a administɾaˈdoɾa pɾepaˈɾow u ʁelaˈtɔɾju

Yes, this sentence uses the normal word order:

Subject + Verb + Object

• A administradora = subject
• preparou = verb
• o relatório = object

So it matches English quite closely:

The administrator prepared the report.

Portuguese can change word order for emphasis, but this version is the most neutral and standard.

Yes. Depending on context, administradora can mean a woman who administers or manages something, not only someone with the exact job title administrator.

For example, it could refer to:

• an administrator
• a manager
• an administrator of a building, company, or system

The exact English translation depends on context, but the grammar of the sentence stays the same.
