Questions & Answers about O autor é inteligente.

What does each word in O autor é inteligente literally mean?

Word by word:

• O = the (masculine, singular definite article)
• autor = author
• é = is (3rd person singular of the verb ser)
• inteligente = intelligent / smart

So the sentence is literally “The author is intelligent.”

Why do we need O before autor? In English we can sometimes just say “Author is intelligent.”

In Portuguese, a noun almost always needs an article (or another determiner) in normal sentences.

• O autor é inteligente. = The author is intelligent. (a specific author or one already known from context)
• Um autor é inteligente. = An author is intelligent. (talking about some author, not a specific one)

Leaving the noun without anything (Autor é inteligente) sounds wrong or extremely telegraphic, like a headline or a note on a diagram, not normal speech.

Can I say Um autor é inteligente instead? What changes?

Yes, but the meaning changes slightly:

• O autor é inteligente.
  Focuses on a specific author: “The author is intelligent.”

• Um autor é inteligente.
  Sounds more like:

  • “An author is intelligent.” (some author, not specified), or
  • In the right context, a generic statement: “An author is (typically) intelligent.”

So o = the, definite.
um = a / an, indefinite.

Why is it é and not está? Aren’t both ser and estar “to be”?

Portuguese has two verbs for “to be”:

• ser (é) – used for more permanent or essential characteristics:

  • O autor é inteligente. = The author is (by nature) intelligent.
  • Ela é alta. = She is tall.

• estar (está) – used for temporary or changing states, locations, feelings:

  • O autor está cansado. = The author is (currently) tired.
  • Ele está em casa. = He is at home.

Intelligence is seen as a characteristic of the person, not a temporary state, so you use é (from ser), not está (from estar).

How do you pronounce O autor é inteligente?

Using an approximate Brazilian Portuguese pronunciation:

• O ≈ “oo”, but very short: [o]
• autor ≈ “ow-TOR”
  
  • IPA: [awˈtoʁ] (or [awˈtoɾ] with a flapped r)
• é ≈ open “eh” (not like the name of the letter “éy”): [ɛ]
• inteligente ≈ “een-teh-lee-ZHEN-chee”
  
  • IPA (Brazilian): [ĩte̞liˈʒẽtʃi] (final -te often sounds like “tchi”)

Said smoothly:
[o awˈtoʁ ɛ ĩte̞liˈʒẽtʃi]

Why does é have an accent mark?

The accent on é serves two main purposes:

1. Stress and vowel quality

   • é is pronounced as an open “eh” sound [ɛ], and it is stressed.
   • Without the accent, e can have a different sound depending on position.

2. Distinguishing words in writing

   • é = “is” (from ser).
   • e = “and”.

So, the accent tells you both how to pronounce the vowel and which word it is.

Why does inteligente end in -e if it’s describing a masculine noun (autor)? I thought masculine adjectives ended in -o.

Portuguese has two common patterns for adjectives:

1. -o / -a pattern (changes with gender)

   • menino inteligente (boy intelligent) – not this one, but for example:
   • menino bonito / menina bonita
     
     • masculine: -o
     • feminine: -a

2. -e (same for masculine and feminine)
   Some adjectives end in -e and do not change for gender, only for number:

   • o autor inteligente (masculine singular)
   • a autora inteligente (feminine singular)
   • os autores inteligentes (masculine plural)
   • as autoras inteligentes (feminine plural)

So inteligente is one of those adjectives that:

• stays inteligente for both masculine and feminine,
• but adds -s in the plural: inteligentes.

What is the plural of O autor é inteligente?

The normal plural is:

• Os autores são inteligentes. = The authors are intelligent.

Changes:

• O → Os (plural definite article)
• autor → autores (add -es)
• é → são (3rd person singular → 3rd person plural of ser)
• inteligente → inteligentes (add -s to make it plural)

How would I say “The author is not intelligent”?

To make a sentence negative in Portuguese, you usually put não right before the verb:

• O autor não é inteligente.
  = The author is not intelligent.

Structure:
[subject] + [não] + [verb] + [rest of the sentence]

Is autor always masculine? How do I say “The (female) author is intelligent”?

Autor is the masculine form. The feminine form is autora.

So:

• O autor é inteligente. = The (male) author is intelligent.
• A autora é inteligente. = The (female) author is intelligent.

Notice the changes:

• O → A (masculine → feminine article)
• autor → autora (masculine → feminine noun)
• inteligente stays the same (same form for both genders).

Can I move inteligente next to autor, like O autor inteligente?

You are changing the structure when you do that:

• O autor é inteligente.

  • Predicate adjective; it is a full sentence:
    “The author is intelligent.”

• O autor inteligente

  • Noun phrase (no verb); it means “the intelligent author”, but it is not a full sentence by itself.

If you want a full sentence with é, the normal order is:

• O autor é inteligente.

If you want to describe the noun inside a larger sentence, you can use:

• O autor inteligente escreveu um livro.
  = The intelligent author wrote a book.

What is the difference between autor and escritor?

Both can translate as “author / writer”, but there are nuances:

• autor

  • Often the creator of a work (book, article, law, crime, project, etc.).
  • Used in more formal or legal contexts too:
    • o autor do livro = the author of the book
    • o autor do crime = the perpetrator of the crime

• escritor

  • Usually means someone whose activity or profession is writing literature or texts:
    • Ela é escritora famosa. = She is a famous writer.

In O autor é inteligente, it’s understood you’re talking about some author (usually of a text or work), and you’re stating a trait about him.
