- Two or more things: add -s (Two cats)

Overview
one cat (un gato) se convierte en two cats (dos gatos)? Esa pequeña -s al final es una de las herramientas más poderosas en inglés. Es la forma básica en que mostramos que hay más de uno de algo.apples, bananas) hasta tus series favoritas de Netflix (friends, episodes). La mayoría de las veces, hacer un sustantivo plural es tan simple como agregar esa única letra. Piénsalo como la configuración predeterminada para los plurales.-s es tu primer gran paso para sonar natural. Es un pequeño cambio que hace una gran diferencia en cómo te entiende la gente.How This Grammar Works
dog, estás hablando de un solo perrito solitario. ¡Pero cuando dices dogs, estás hablando de dos, tres o un parque lleno de ellos!-s es un sufijo, que es solo una palabra elegante para una letra o grupo de letras que se agrega al final de una palabra para cambiar su significado. En este caso, cambia el significado de singular (uno) a plural (más de uno). Es un truco de eficiencia en el idioma.one chair, five chairs), personas (one teacher, ten teachers) e incluso ideas abstractas (one problem, many problems). Es tan común que tu cerebro aprenderá rápidamente a hacerlo automáticamente.
Formation Pattern

When To Use It
-s siempre que hables de más de un sustantivo contable. Un sustantivo contable es cualquier cosa a la que le puedas poner un número delante.- Hacer listas: Cuando le escribes a un amigo qué llevar a una fiesta:
Necesitamos
snacks,drinksygames. - Hablar de pasatiempos: En tu perfil de citas:
Me encanta leer
books, vermoviesy probarrestaurantsnuevos. - Comprar en línea: No estás buscando un
shoe, estás buscando un par deshoes. Agregas tresshirtsa tu carrito. - Declaraciones generales: Cuando haces una declaración general sobre algo, a menudo usas el plural. Por ejemplo,
Los
No estás hablando de un gato específico, sino de los gatos en general.Catsson animales independientes. - Contar cualquier cosa: Úsalo cada vez que tengas un número (que no sea uno) antes de un sustantivo:
two dogs,100 reasons,a million dollars.
-s.
Common Mistakes
-s: Este es el más básico. I have two cat. (✗)
I have two cats. (✓). Es un error fácil cuando piensas rápido o traduces de un idioma sin reglas de plural similares.
- 1Usar un apóstrofo (
's): ¡Esto es muy importante! Un apóstrofo es para posesión (pertenencia a alguien) o contracciones, no para plurales. "I love Saturday's.(✗) es incorrecto a menos que ames algo que pertenece al sábado. La forma correcta es
I loveSaturdays." (✓). - 2Usar en exceso la regla de la
-s: Algunas palabras son irregulares y no llevan-s. Por ejemplo,one childse convierte entwo children, notwo childs(✗).one personse convierte entwo people, notwo persons(✗) en la mayoría de los contextos. - 3Sustantivos que terminan en un sonido sibilante: Las palabras que terminan en
-s,-sh,-ch,-xo-znecesitan-espara que sean más fáciles de pronunciar.One boxse convierte entwo boxes, notwo boxs(✗). ¡Intentar decirboxses un verdadero trabalenguas!
Contrast With Similar Patterns
-s es la estrella del espectáculo, tiene algunos coprotagonistas para diferentes tipos de palabras. Es útil verlos uno al lado del otro.-svs.-es: La-ses para la mayoría de los sustantivos. La-eses para los sustantivos que terminan en sonidos sibilantes (-s,-sh,-ch,-x,-z) para hacerlos pronunciables. Piensa enbus→busesowitch→witches. Laeagrega una sílaba extra. Así que no solo estás agregando-s, estás agregando una pequeña vocal para ayudar.-svs. Plurales Irregulares: Algunas de las palabras más antiguas y comunes en inglés tienen sus propias formas plurales especiales. No siguen la regla de la-sen absoluto. Son rebeldes. Por ejemplo:man→men,woman→women,foot→feet,mouse→mice. Simplemente tienes que memorizarlos. Son como los VIP del mundo plural; no siguen las reglas normales.-svs. Plurales Invariables: Algunos sustantivos son perezosos y no cambian en absoluto.One sheepestwo sheep.One fishpuede sertwo fish(especialmente si son de la misma especie). La palabra sigue siendo la misma. El contexto te dice si es singular o plural.
-s es tu opción principal, siempre mantente atento a las palabras que necesitan una terminación ligeramente diferente o que deciden romper las reglas por completo.Quick FAQ
P: ¿Es siempre solo -s?
R: ¡Mayormente, sí! Pero para las palabras que terminan en -s, -sh, -ch, -x, -z, agregarás -es (p. ej., boxes). Y algunas palabras son irregulares (children, feet).
P: ¿Por qué no puedo escribir photo's para el plural de photo?
R: El apóstrofo ('s) muestra posesión, no plural. The photo's color significa el color de la foto. Photos solo significa más de una foto.
P: ¿Qué pasa con las palabras que terminan en -y?
R: ¡Buena pregunta! Si una vocal viene antes de la -y (como en toy), solo agregas -s → toys. Si viene una consonante antes (como en city), cambias la y a i y agregas -es → cities.
P: ¿Funciona esto para todos los sustantivos?
R: Funciona para todos los sustantivos contables. No puedes contar water o happiness, por lo que no puedes decir waters o happinesses de la misma manera. Estos se llaman sustantivos incontables y tienen sus propias reglas.

Smart Tips
Always use the plural form without 'the'.
Use the plural noun to sound more natural.
Immediately prepare your mouth to make the 's' sound at the end of the next word.
Check if you are counting or showing ownership. No apostrophe for counting!
Pronunciación
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.
List Intonation
Apples ↗, oranges ↗, and bananas ↘.

Notas culturales
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.
