Overview
less y fewer. En español, tenemos la suerte de contar con una palabra universal, menos, que aplicamos generosamente a cualquier escenario: decimos menos gente, menos agua, menos problemas o menos tiempo. Sin embargo, el inglés, en su afán por categorizar el mundo de forma lógica y matemática, nos obliga a detenernos un segundo antes de hablar para hacernos una pregunta fundamental: ¿Lo que estoy describiendo se puede contar uno por uno, o es una masa indivisible?less y fewer no es solo una cuestión de aprobar un examen; es la marca de un hablante que ha pasado del nivel intermedio a uno avanzado y preciso. Esta distinción se basa en el concepto de sustantivos contables (countable nouns) y no contables (uncountable nouns). Aunque en la vida cotidiana verás que incluso los nativos confunden estos términos (seguramente has visto el cartel de 10 items or less en el supermercado), en contextos profesionales, académicos o simplemente para sonar más natural y educado, es vital saber cuándo usar cada uno.less cuando deberías usar fewer puede sonar un poco descuidado, similar a cuando alguien en español dice hubieron en lugar de hubo. En esta guía, vamos a desglosar esta regla desde nuestra perspectiva como hispanohablantes, aprovechando las similitudes de nuestros idiomas y alertando sobre las trampas donde solemos caer.less y fewer, primero debemos reconciliarnos con la naturaleza de los sustantivos en inglés. La gramática inglesa divide la realidad en dos grandes grupos:- 1Countable Nouns (Sustantivos Contables): Son cosas que puedes separar en unidades individuales. Puedes ponerles un número delante.
- Ejemplos:
car(un coche, dos coches),apple(una manzana, tres manzanas),problem(un problema, varios problemas). - Regla de oro: Si tiene una forma plural (termina en
-so es un plural irregular comopeople), es muy probable que sea contable. - Con estos sustantivos, usamos
fewer.
- 1Uncountable Nouns (Sustantivos Incontables o de Masa): Son sustancias, conceptos abstractos o colectivos que vemos como un todo. No puedes decir
un dineroodos informaciones.
- Ejemplos:
water(agua),money(dinero),advice(consejo),time(tiempo),sugar(azúcar). - Regla de oro: Estos sustantivos normalmente no tienen plural. No dices
waterspara hablar de la cantidad de agua que bebes. - Con estos sustantivos, usamos
less.
menos para ambos, la lógica de base es la misma. Tú sabes que el aire no se cuenta por unidades, pero las sillas sí. El truco está en que el inglés es mucho más estricto con esta lógica gramatical.Less o Fewer? |bottles | fewer bottles |water | less water |people | fewer people |information | less information |people (gente) en inglés es plural. Aunque en español decimos la gente es (singular), en inglés decimos people are (plural).fewer people, nunca less people (aunque lo escuches en canciones o series, técnicamente es incorrecto).less y fewer es bastante directa, ya que ambos funcionan como determinantes que se colocan justo antes del sustantivo. Sin embargo, la clave está en la concordancia del sustantivo que les sigue.fewer:Fewer + [Sustantivo Contable en PLURAL]I have fewer books than you.(Tengo menos libros que tú).There are fewer students in class today.(Hay menos estudiantes en clase hoy).We should make fewer mistakes.(Deberíamos cometer menos errores).
less:Less + [Sustantivo Incontable en SINGULAR]I have less money than I thought.(Tengo menos dinero del que pensaba).Add less salt to the soup.(Añade menos sal a la sopa).This task requires less effort.(Esta tarea requiere menos esfuerzo).
fewer + plural | fewer chairs | Las sillas se cuentan una a una. |less + singular | less furniture | furniture (muebles) es incontable en inglés. |fewer + plural | fewer opportunities | Las oportunidades son unidades contables. |less + singular | less space | El espacio es una magnitud continua. |less también puede funcionar como adverbio para modificar adjetivos o verbos, algo que fewer no puede hacer. Por ejemplo: I am less tired today (Estoy menos cansado hoy) o I sleep less than before (Duermo menos que antes). En estos casos, no hay confusión posible, siempre es less.- Usa

less, incluso si el sustantivo parece plural.bloque o un concepto único, no como unidades individuales.- 1Dinero:
It costs less than fifty dollars.(Lo vemos como un precio total, no como 50 billetes individuales). - 2Tiempo:
I finished the exam in less than ten minutes.(Vemos los 10 minutos como un periodo de tiempo, no como segundos contados uno a uno). - 3Distancia:
The station is less than three miles away.(Vemos la distancia como un trayecto total). - 4Peso/Volumen:
The baby weighs less than eight pounds.
I have fewer than five dollar bills, estás hablando de los billetes físicos (contables). Pero si dices It costs less than five dollars, hablas del valor monetario (incontable).Less Peoplegente es una palabra singular (la gente es buena). Por inercia, tendemos a pensar que
people es incontable y decimos less people.- Error:
There are less people in the street. - Corrección:
There are fewer people in the street. - Por qué sucede: Porque traducimos mentalmente

less/fewer con sus primos hermanos: much/many y little/few. La lógica es exactamente la misma, lo cual es una excelente noticia para ti, porque una vez que aprendes la lógica de contable/incontable, desbloqueas varias reglas a la vez.less (less water) | fewer (fewer bottles) |much (much time) | many (many hours) |little (little sugar) | few (few cookies) |I don't have much money(No tengo mucho dinero) →I have less money than you(Tengo menos dinero que tú).I don't have many coins(No tengo muchas monedas) →I have fewer coins than you(Tengo menos monedas que tú).
mucho/a y muchos/as (cambiamos el género y el número), pero en inglés la distinción es puramente sobre la naturaleza del objeto. Si puedes contarlo, usa la columna de la derecha. Si no puedes, la de la izquierda.less con sustantivos en plural alguna vez?less than 20 miles. Fuera de eso, en inglés formal, less siempre va con singular incontable y fewer con plural contable.una información, dos informaciones? En español sí, pero en inglés suena fatal (one information). Si no puedes contarlo con números naturales de forma directa, trátalo como incontable y usa less.less más común que fewer en la vida real?less para todo, igual que nosotros usamos menos. Sin embargo, si quieres demostrar un nivel B1 sólido o avanzar hacia el B2, empezar a usar fewer correctamente te hará destacar inmediatamente como alguien que realmente entiende la estructura del idioma.Less rima con mess (lío) o dress (vestido). Fewer tiene dos sílabas: /fjuː-ə/. Asegúrate de pronunciar bien esa j inicial (como una 'i' muy corta) para que no suene como fuer.Quantifier Usage by Noun Type

Preguntas frecuentes (8)
Grammatically, yes. It should be `fewer` because items are countable. However, it is so common that it's accepted in casual English.
Because distance is seen as a total amount or a single measurement, not as individual miles you count one by one.
In formal writing, no. Use `fewer people`. In casual speech, you will hear `less people`, but it's better to avoid it.
`Less` refers to quantity (amount), while `lesser` refers to quality, importance, or rank (e.g., 'a lesser known artist').
No, but it is becoming more restricted to formal writing and professional contexts.
Usually, yes. 'Less than 50%' is standard because it refers to a portion of a whole.
This is a formal idiom used to emphasize a surprisingly large number (e.g., 'No fewer than 100 people attended').
Yes! In sentences like 'I eat less,' it is an adverb. In this case, you never use 'fewer'.
