What is agreement in Portuguese?
Agreement in Portuguese means changing words so they match in gender and number or person. In English we say he is, they are; in Portuguese similar changes happen more often, especially with adjectives, articles, and verbs. Learning agreement makes your Portuguese understandable and more natural to native speakers.
Key terms to know
gênero – gender: masculino or feminino
número – number: singular or plural
concordância verbal – subject-verb agreement
concordância nominal – agreement between nouns, articles, adjectives, and pronouns
Gender agreement with articles and adjectives
In Brazilian Portuguese, nouns have gender. Most masculine nouns end in -o and feminine nouns end in -a, but there are many exceptions. Articles and adjectives must match the noun’s gender and number.
Basic pattern: singular
Use the definite articles o for masculine singular and a for feminine singular. Adjectives change: bonito becomes bonita, pequeno becomes pequena.
Example: o carro vermelho means the red car.
Example: a casa bonita means the pretty house.
Basic pattern: plural
For plural definite articles use os for masculine plural and as for feminine plural. Adjectives also become plural: vermelho becomes vermelhos, bonita becomes bonitas.
Example: os carros vermelhos means the red cars.
Example: as casas bonitas means the pretty houses.
Beginner vocabulary for gender practice
o livro – the book (masculine)
a mesa – the table (feminine)
o aluno – the student (male)
a aluna – the student (female)
o amigo / a amiga – the friend (m/f)
Number agreement: singular vs plural
Forming the plural usually adds -s to the noun and adjective. If a word ends in -m, change -m to -ns. Words ending in -ão have three plural forms (-ões, -ãos, -ães) and often require memorization. For beginners, focus on regular plurals.
Regular plural examples
Singular: o carro
Plural: os carros
Singular: a maçã
Plural: as maçãs
Singular: o jovem
Plural: os jovens
Beginner tip
When you turn a noun plural, always change the article and any adjectives that describe it. Practice by describing pictures: a menina feliz becomes as meninas felizes.
Subject-verb agreement (concordância verbal)
Verbs must agree with the subject in person and number. That means the verb ending changes for eu, tu, você/ele/ela, nós, vocês/eles/elas. For beginners, focus on present indicative of regular verbs ending in -ar, -er, -ir.
Present tense endings: regular verbs
Verb example: falar (to speak)
eu falo
você/ele/ela fala
nós falamos
vocês/eles/elas falam
Verb example: comer (to eat)
eu como
você/ele/ela come
nós comemos
vocês/eles/elas comem
Verb example: abrir (to open)
eu abro
você/ele/ela abre
nós abrimos
vocês/eles/elas abrem
Practical examples for beginners
Eu falo português. – I speak Portuguese.
Ela come arroz. – She eats rice.
Nós abrimos a janela. – We open the window.
Common beginner mistake: mixing subject and verb
Do not use eu with third person endings. Incorrect: eu fala. Correct: eu falo. For você, remember that European Portuguese uses tu differently, but in Brazilian Portuguese você uses third person forms: você fala, not você falas.
Agreement after compound subjects and with pronouns
When two or more subjects are joined by e (and), the verb usually goes to plural. If subjects differ in gender, masculine plural takes precedence for mixed groups.
Examples
O pai e a mãe chegam hoje. – The father and the mother arrive today.
A Ana e a Maria são amigas. – Ana and Maria are friends.
Mixed gender: O João e a Maria são casados. – João and Maria are married. Note the masculine plural agreement.
Using pronouns
Personal pronouns affect verb forms: eu, você, ele, ela, nós, vocês, eles, elas. Demonstrative pronouns like este, esta change to match gender and number: este carro, esta casa, estes carros, estas casas.
Example: Esta cadeira é confortável.
Example: Estas cadeiras são confortáveis.
Agreement with possessive adjectives
Possessive adjectives meu, minha, seus, nossas must agree in gender and number with the thing possessed, not the possessor. This is different from English, so learners should pay attention.
Examples
Meu livro – my book (masculine)
Minha caneta – my pen (feminine)
Nossos amigos – our friends (masculine plural)
Nossas amigas – our friends (feminine plural)
Practical sentence
Mina mãe is incorrect. Correct: Minha mãe chega às oito. – My mother arrives at eight.
Adjective placement and special cases
Adjectives usually follow the noun, but some common adjectives can come before for emphasis or fixed expressions. Placement does not change agreement rules: whether before or after, the adjective must match the noun.
Examples
Um carro rápido – a fast car
Um bom amigo – a good friend (bonito variations: um bom / uma boa)
Uma mulher inteligente – an intelligent woman
Invariant adjectives and neutral forms
Some adjectives do not change with gender when they end in -e or a consonant. Example: o estudante inteligente, a estudante inteligente. They change in number but not gender: os estudantes inteligentes, as estudantes inteligentes.
Common beginner mistakes and tips
Mistake: forgetting to change the article when the noun is plural. Incorrect: o livros bonitos. Correct: os livros bonitos.
Mistake: using eu with você verb form. Incorrect: eu fala. Correct: eu falo.
Mistake: making possessive agree with possessor instead of object. Incorrect: meu mãe. Correct: minha mãe.
Tip: Learn noun gender with the article. Instead of memorizing livro, learn o livro. That way gender comes naturally.
Tip: Practice with flashcards that show full phrases: a casa grande instead of just casa or grande.
Tip: When in doubt about adjective placement, place the adjective after the noun: o problema difícil is safe and natural.

B: Seu irmão é estudante?
Practical exercises for beginners
Exercise 1: Change to plural and correct articles
o amigo simpático -> os amigos simpáticos

Eu (falo/fala) português. -> eu falo
Ela (come/comem) agora. -> ela come
Exercise 3: Correct the possessive

nosso casa -> nossa casa
Resources and next steps
Start with simple sentences and gradually add new vocabulary that includes articles and adjectives. Use short dialogues, menus, and signs to spot agreement in context. Practice with a tutor or language partner focusing on immediate correction of gender and verb endings.
Useful mini-goals: correctly use definite articles with 50 common nouns, conjugate five regular verbs in present tense for all persons, and describe five pictures using plural and singular agreement.
Conclusion
Mastering agreement in Brazilian Portuguese requires attention to gender, number, and verb forms. Beginners should focus on learning nouns with articles, practicing regular verb endings, and using short realistic sentences. With targeted practice on the examples and exercises here, learners will quickly improve clarity and confidence in everyday Portuguese communication.
