Overview
shoe? Se siente un poco solitario, ¿no? En inglés, uno de cualquier cosa suele estar bien, pero la vida es mejor con más.followers, burgers o vacations, necesitas saber cómo convertir uno en muchos. Este es el espíritu de las formas plurales. La mayoría de las veces, solo lanzas una s al final y listo.picante. A veces necesitas una es, y otras veces tienes que echar a la y e invitar a ies a la fiesta. Hacer esto bien te hace sonar como un profesional, ya sea que estés texteando en tu chat grupal o escribiendo un correo formal a un profesor.friend (triste) y tener muchos friends (asombroso). No te preocupes, las reglas son bastante lógicas una vez que ves el patrón. Es básicamente como un juego de emparejar terminaciones.appendices.How This Grammar Works
singular a la versión de uno de una palabra. La versión de más de unoes el plural. A diferencia de algunos idiomas donde cambia toda la oración, en inglés normalmente solo cambia el sustantivo.
-s. Por ejemplo, tu phone se convierte en phones.s. Intenta decir bus-s muy rápido.-es a las palabras que terminan en s, x, z, ch o sh. Esto añade una sílaba extra que hace que la palabra sea más fácil de escuchar.y. Si una palabra termina en consonante más y, como city, la y es un poco solitaria. Se va, y -ies toma su lugar.y, como en boy, la y se queda donde está y solo recibe una s. Piensa en ello como si la y estuviera protegida por su amiga la vocal. ¡Es un punto gramatical muy social!

Common Mistakes
- La trampa de la Y: Muchas personas cambian cada
ypories. Recuerda:boyse convierte enboys, noboies. Solo cambia laysi hay una consonante (comot,r,l) antes de ella. - Olvidar el -es: Olvidar la
een palabras comobusesoboxes. Escribirbus'ses para posesión, ybusses... bueno, no es un plural estándar. - El error del apóstrofe: ¡Este es uno enorme! Nunca uses un apóstrofe ( ' ) para formar un plural.
Apple'ssignifica que algo le pertenece a la manzana.Applessignifica más de una manzana. - Pronunciación: A veces la gente olvida pronunciar la sílaba extra de
-es.Busesdebe sonar comobus-iz, no solo como un sonido deslargo. - Pluralizar de más: Algunas palabras en inglés no aceptan una
s(comoinformationowater), pero por ahora, ¡solo concéntrate en las que sí lo hacen! - ✗
I have two toyies.→ ✓I have two toys.(Regla de vocal + y) - ✗
She has three boxs.→ ✓She has three boxes.(Regla de terminación en x) - ✗
Look at the puppy's!→ ✓Look at the puppies!(¡Sin apóstrofe para plurales!)
Contrast With Similar Patterns
-s del plural con otras terminaciones en s en inglés. Primero, está el 's posesivo. Esto indica pertenencia.my friend's house, significa que la casa le pertenece a un amigo. Si dices my friends, significa que tienes muchos amigos. Segundo, está la tercera persona del singular en los verbos.he plays, estamos añadiendo una s a un verbo, no a un sustantivo. Se ve igual, pero el trabajo es diferente. Los sustantivos usan la s para mostrar cantidad; los verbos usan la s para concordar con el sujeto.man se convierten en men o child en children. Estos no siguen nuestras reglas de -s/-es/-ies para nada.bottles, pero simplemente tienes water.waters (normalmente). ¡Entender primero las reglas regulares te da una base sólida para que puedas detectar a los rebeldes más fácilmente después! Es como aprender las reglas de la carretera antes de empezar a conducir un coche de carreras.Quick FAQ
¿Todas las palabras que terminan en y se convierten en ies?
¡No! Solo si una consonante va antes de la y. Si hay una vocal (a, e, i, o, u), solo añade s.
¿Por qué añadimos -es en lugar de solo -s?
¡Todo es por el sonido! Es muy difícil decir sh o ch seguido de una s rápida. La e nos da un poco de espacio para respirar.
¿Puedo usar un apóstrofe para los plurales si la palabra es rara?
Nop. Nunca. Los apóstrofes son para posesión o contracciones (como it's), no para hacer cosas plurales.
¿Es stories o storys?
Es stories porque la r es una consonante. Si estás escribiendo un blog, ¡asegúrate de escribir bien tus stories!
¿Hay palabras que no cambian en absoluto?
Sí, como sheep o fish, pero esas son irregulares. Para el nivel A1, ¡concéntrate primero en los patrones -s, -es y -ies!
¿Qué pasa con las palabras que terminan en o?
¡Gran pregunta! Algunas llevan s (photos) y otras llevan es (tomatoes). Cubriremos esas en una lección aparte, ¡pero la -s suele ser una apuesta segura para palabras tecnológicas modernas!
¿Cómo sé si debo usar -ies?
Mira la letra antes de la y. Si es una consonante, ¡haz el cambio! Si es una vocal, mantén la y.
¿Necesito escribir los plurales con mayúscula?
Solo si el sustantivo en singular ya la llevaba, como Saturdays o Americans.

Smart Tips
Check the neighbor! If the neighbor is a consonant, 'y' becomes 'ies'. If it's a vowel, 'y' stays.
Make sure you add an extra 'iz' sound at the end. Don't rush it!
Never use an apostrophe (') unless you are talking about ownership.
Always look ahead. If the noun is plural, you MUST use 'there are'.
Pronunciación
The /s/ sound
Used after voiceless sounds like p, t, k, f.
The /z/ sound
Used after voiced sounds like b, d, g, v, and all vowels.
The /ɪz/ sound
Used after s, x, z, ch, sh. This adds an extra syllable.

Asociación visual

Rhyme

Story
A little 'y' was lonely at a party. A consonant friend came over, and the 'y' got so excited it turned into an 'i' and invited 'es' to join them. But when a vowel friend came over, the 'y' stayed the same and just invited 's' to stand next to them.

Desafío
Look around your room. Find 5 different objects. Say the name of the object, then say how many there would be if you had two of them (e.g., 'One lamp, two lamps').
Notas culturales
Using plurals correctly is a sign of basic literacy. In many English-speaking cultures, omitting the plural 's' can make a speaker sound very uneducated or like a non-native beginner.
In some dialects like AAVE, the plural -s is sometimes omitted if a number is already present, as the number already indicates plurality.
In some northern UK dialects, you might hear 'ten pound' instead of 'ten pounds' when talking about money.
The -s plural comes from the Old English masculine nominative plural ending '-as'.

Preguntas frecuentes (8)
It's about sound! Words ending in 'hissing' sounds like s, x, ch, and sh need the extra 'e' to make the plural sound clear and easy to say.
Because there is a vowel ('o') before the 'y'. We only change 'y' to 'ies' if there is a consonant before it.
Yes! Some words like `sheep`, `fish`, and `deer` are the same in singular and plural. These are called irregular nouns.
Yes! In words like `buses` or `watches`, the `-es` is pronounced like 'iz', adding a second syllable to the word.
Yes. For proper names, we usually just add 's'. For example, 'The Kennedys' or 'There are two Marys in my class.'
It's `quizzes`. Note that we double the 'z' before adding '-es'!
Yes, but it's irregular. It doesn't follow the -s rule. You will learn those in the next lesson!

-s / -es
In Spanish, adjectives must also be pluralized (e.g., 'los gatos negros'), whereas in English, adjectives never change.
-s
In spoken French, the -s is usually silent. You only know it's plural because of the article (le vs les).
Various (-e, -en, -er, -s)
English is much simpler because it mostly uses just one suffix (-s).
None
Japanese uses 'counters' or context instead of changing the noun ending.
