Um Gato, Dois Gatos — Plurais Simples com -s
Grammar Rule in 30 Seconds
To talk about more than one thing in English, simply add the letter -s to the end of the word.
- One thing: no -s (One cat)
- Two or more things: add -s (Two cats)
- Zero things: also add -s (Zero cats)
Overview
one cat (um gato) se torna two cats (dois gatos)? Esse pequeno -s no final é uma das ferramentas mais poderosas do inglês. É a forma básica de mostrarmos que há mais de uma coisa.apples, bananas) aos seus programas favoritos da Netflix (friends, episodes). Na maioria das vezes, tornar um substantivo plural é tão simples quanto adicionar essa única letra. Pense nisso como a configuração padrão para plurais.-s é o seu primeiro grande passo para soar natural. É uma pequena mudança que faz uma grande diferença na forma como as pessoas o entendem.How This Grammar Works
dog, está a falar de um único e solitário cachorrinho. Mas quando diz dogs, está a falar de dois, três ou um parque inteiro cheio deles!-s é um sufixo, que é apenas uma palavra chique para uma letra ou grupo de letras adicionadas ao final de uma palavra para mudar o seu significado. Neste caso, muda o significado de singular (um) para plural (mais de um). É um truque de eficiência na língua.one chair, five chairs), pessoas (one teacher, ten teachers) e até ideias abstratas (one problem, many problems). É tão comum que o seu cérebro aprenderá rapidamente a fazê-lo automaticamente.
Formation Pattern

-s diretamente no final.
book + -s = books.

When To Use It
-s sempre que está a falar de mais de um substantivo contável. Um substantivo contável é qualquer coisa à frente da qual você pode colocar um número.- Fazer listas: Quando está a enviar uma mensagem a um amigo sobre o que levar para uma festa:
Precisamos de
snacks,drinksegames. - Falar sobre passatempos: No seu perfil de encontros:
Adoro ler
books, vermoviese experimentarrestaurantsnovos. - Comprar online: Você não está à procura de um
shoe, está à procura de um par deshoes. Você adiciona trêsshirtsao seu carrinho. - Declarações gerais: Quando faz uma declaração geral sobre algo, usa frequentemente o plural. Por exemplo,
Você não está a falar de um gato específico, mas de gatos em geral.Catssão animais independentes. - Contar qualquer coisa: Use-o sempre que tiver um número (diferente de um) antes de um substantivo:
two dogs,100 reasons,a million dollars.
-s.
Common Mistakes
-s: Este é o mais básico. I have two cat. (✗)
I have two cats. (✓). É um erro fácil quando se está a pensar rápido ou a traduzir de uma língua sem regras de plural semelhantes.
- 1Usar um apóstrofo (
's): Este é um erro enorme! Um apóstrofo é para posse (pertencente a alguém) ou contrações, não para plurais. "I love Saturday's.(✗) está errado, a menos que você ame algo que pertence ao sábado. A forma correcta é
I loveSaturdays." (✓). - 2Uso excessivo da regra do
-s: Algumas palavras são irregulares e não levam-s. Por exemplo,one childtorna-setwo children, nãotwo childs(✗).one persontorna-setwo people, nãotwo persons(✗) na maioria dos contextos. - 3Substantivos terminados num som sibilante: Palavras que terminam em
-s,-sh,-ch,-xou-zprecisam de-espara as tornar mais fáceis de dizer.One boxtorna-setwo boxes, nãotwo boxs(✗). Tentar dizerboxsé um verdadeiro trava-línguas!
Contrast With Similar Patterns
-s é a estrela do espectáculo, tem alguns coadjuvantes para diferentes tipos de palavras. É útil vê-los lado a lado.-svs.-es: O-sé para a maioria dos substantivos. O-esé para substantivos que terminam em sons sibilantes (-s,-sh,-ch,-x,-z) para os tornar pronunciáveis. Pense embus→busesouwitch→witches. Oeadiciona uma sílaba extra. Portanto, você não está apenas a adicionar-s, está a adicionar uma pequena vogal para ajudar.-svs. Plurais Irregulares: Algumas das palavras mais antigas e comuns em inglês têm as suas próprias formas de plural especiais. Elas não seguem a regra do-sde todo. São rebeldes. Por exemplo:man→men,woman→women,foot→feet,mouse→mice. Você só tem de as memorizar. São como os VIPs do mundo do plural; não seguem as regras normais.-svs. Plurais Invariáveis: Alguns substantivos são preguiçosos e não mudam de todo.One sheepétwo sheep.One fishpode sertwo fish(especialmente quando são da mesma espécie). A palavra permanece a mesma. O contexto diz-lhe se é singular ou plural.
-s é a sua opção principal, esteja sempre atento a palavras que precisam de um final ligeiramente diferente ou que decidem quebrar as regras completamente.Quick FAQ
P: É sempre apenas -s?
R: Principalmente, sim! Mas para palavras que terminam em -s, -sh, -ch, -x, -z, você adicionará -es (por exemplo, boxes). E algumas palavras são irregulares (children, feet).
P: Porque não posso escrever photo's para o plural de photo?
R: O apóstrofo ('s) mostra posse, não plural. The photo's color significa a cor da foto. Photos significa apenas mais do que uma foto.
P: E as palavras que terminam em -y?
R: Boa pergunta! Se uma vogal vier antes do -y (como em toy), você apenas adiciona -s → toys. Se uma consoante vier antes (como em city), você muda o y para i e adiciona -es → cities.
P: Isso funciona para todos os substantivos?
R: Funciona para todos os substantivos contáveis. Você não pode contar water ou happiness, então não pode dizer waters ou happinesses da mesma forma. Estes são chamados de substantivos incontáveis e têm as suas próprias regras.

Check if you are counting or showing ownership. No apostrophe for counting!

The /s/ sound
If the word ends in a 'quiet' sound (like p, t, k, f), the -s sounds like a snake hiss.
The /z/ sound
If the word ends in a 'vibrating' sound (like b, d, g, l, m, n, r, v, or any vowel), the -s sounds like a buzzing bee.

Notas culturais
English speakers are very specific about number. Failing to use the plural can make you sound like a child or very uneducated.
In the UK, some collective nouns (groups of people) can be treated as plural even without an -s, like 'The team are playing well.'
Americans almost always use the singular for collective groups ('The team is playing well'), but always use the -s for individual items.
The -s plural comes from the Old English 'as' ending, which was used for a specific group of masculine nouns.
