Portuguese grammar, similar to other Romance languages like Spanish, is a flexive language with intricate rules for word formation. The language uses inflection to express various grammatical categories such as tense, case, mood, and number. This article covers the essential aspects of Portuguese grammar with detailed examples to help you grasp the basics and improve your language skills.

Nouns and Adjectives

In Portuguese, nouns and adjectives must agree in gender and number. The language features two genders—masculine and feminine—and two numbers—singular and plural.

• Masculine Singular: o livro (the book)
  • Example: O livro está na mesa. (The book is on the table.)
• Feminine Singular: a casa (the house)
  • Example: A casa é grande. (The house is big.)
• Masculine Plural: os livros (the books)
  • Example: Os livros são interessantes. (The books are interesting.)
• Feminine Plural: as casas (the houses)
  • Example: As casas são antigas. (The houses are old.)

Adjectives must match the noun they describe:

• Masculine Singular: um carro vermelho (a red car)
  • Example: Ele comprou um carro vermelho. (He bought a red car.)
• Feminine Singular: uma casa vermelha (a red house)
  • Example: Ela vive em uma casa vermelha. (She lives in a red house.)
• Masculine Plural: carros vermelhos (red cars)
  • Example: Os carros vermelhos estão estacionados. (The red cars are parked.)
• Feminine Plural: casas vermelhas (red houses)
  • Example: As casas vermelhas são muito bonitas. (The red houses are very beautiful.)

Verbs and Conjugation

Portuguese verbs are inflected according to tense and subject. There are three primary conjugation groups based on verb endings: -ar, -er, and -ir. The three main tenses are present, past, and future.

• Present Tense: eu falo (I speak)
  • Example: Eu falo português. (I speak Portuguese.)
• Past Tense: eu falei (I spoke)
  • Example: Eu falei com ela ontem. (I spoke with her yesterday.)
• Future Tense: eu falarei (I will speak)
  • Example: Eu falarei sobre isso amanhã. (I will speak about it tomorrow.)

Verbs are categorized by their endings:

• -ar Verbs: falar (to speak)
• -er Verbs: comer (to eat)
• -ir Verbs: viver (to live)

Sentence Structure

Portuguese typically follows a Subject-Verb-Object (SVO) structure. For example:

• Statement: Eu estudo português. (I study Portuguese.)
• Question: Você estuda português? (Do you study Portuguese?)

Portuguese is a null subject language, meaning the subject can be omitted when it’s understood from the context:

• Without Subject: Estudo português. (I study Portuguese.)

Copular Verbs

Portuguese uses two copular verbs, “ser” and “estar,” to express states of being. The choice between them depends on whether the state is considered permanent or temporary.

• Ser: Indicates a permanent or inherent quality.
  • Example: Ele é médico. (He is a doctor.)
• Estar: Indicates a temporary or situational state.
  • Example: Ela está cansada. (She is tired.)

Personal Pronouns

Portuguese pronouns differ between European and Brazilian Portuguese. Here’s a breakdown:

Singular Pronouns:

• Portugal: eu (I), tu (you), ele (he), ela (she)
• Brazil: eu (I), você (you), ele (he), ela (she)

Plural Pronouns:

• Portugal: nós (we), vós (you), eles/elas (they)
• Brazil: nós (we), vocês (you), eles/elas (they)

Prepositions

Prepositions in Portuguese describe relationships between words. Here are some common prepositions:

• De: of, from
  • Example: O livro é de Maria. (The book is from Maria.)
• Para: to, for
  • Example: Vou para a escola. (I am going to school.)
• Sobre: about, on
  • Example: Falei sobre o livro. (I spoke about the book.)
• Atrás: behind
  • Example: A loja está atrás do restaurante. (The store is behind the restaurant.)

Articles

Portuguese articles must agree in gender and number with the nouns they precede:

• Definite Articles:
  • Masculine Singular: o (the)
    • Example: O carro é rápido. (The car is fast.)
  • Feminine Singular: a (the)
    • Example: A mesa é grande. (The table is big.)
  • Masculine Plural: os (the)
    • Example: Os carros são caros. (The cars are expensive.)
  • Feminine Plural: as (the)
    • Example: As cadeiras são confortáveis. (The chairs are comfortable.)

    • Example: Um livro está na mesa. (A book is on the table.)
  • Feminine Singular: uma (a)
    • Example: Uma casa nova. (A new house.)
  • Masculine Plural: uns (some)
    • Example: Uns livros são interessantes. (Some books are interesting.)
  • Feminine Plural: umas (some)
    • Example: Umas casas antigas. (Some old houses.)

Pronunciation and Diacritics

Portuguese pronunciation varies between Portugal and Brazil. Key differences include:

• Letter “l”:
  • Brazil: animal (sounds like “book”)
  • Portugal: animal (sounds like “alternative”)
• Letter “d”:
  • Brazil:
    • tarde (late) pronounced like “judge”
    • dente (tooth) pronounced like “day”
  • Portugal:
    • tarde and dente pronounced like “day”

Diacritics are symbols used to modify pronunciation:

• Til (~): Indicates nasal sound (e.g., pão—bread)
• Acento agudo (´): Indicates an open vowel (e.g., café—coffee)
• Acento circunflexo (^): Indicates a closed vowel (e.g., avô—grandfather)

Gender

Identifying the gender of nouns can be challenging. Here are some rules:

• Masculine Endings: Usually end in -o (e.g., carro—car)
• Feminine Endings: Usually end in -a (e.g., flor—flower)
• Exceptions: Some words end in -ão (e.g., pão—bread) and can be masculine or feminine depending on the context.

Asking Questions and Negative Form

Forming questions is straightforward in Portuguese—just add a question mark and raise your intonation:

• Question: Você fala português? (Do you speak Portuguese?)

To form negative sentences, place “não” before the verb:

• Negative: Eu não estudo. (I do not study.)

Diminutives and Augmentatives

Diminutives express small size or endearment, while augmentatives indicate large size or significance:

• Diminutive: -inho (masculine) and -inha (feminine)
  • Example: gatinho (kitten, implying cuteness)
• Augmentative: -ão (masculine) and -ona (feminine)
  • Example: livrão (big book, implying importance)

Conclusion

Portuguese grammar, though complex, becomes manageable with practice and understanding. Familiarizing yourself with these rules and examples is crucial for mastering the language.
