pelo en tu sopa (quizás restos diminutos). Pero si dices There is a hair in my soup, estás señalando un hilo específico, largo y molesto. Esa pequeña

hair(singular e incontable).

hair no es único en inglés. Existen otros sustantivos que cambian de significado dependiendo de si los tratamos como masa (incontables) o como unidades (contables). Entender estos paralelismos te ayudará a asimilar la lógica del idioma.Paper | El material: I need some paper to write. | Un documento o periódico: I bought a paper. |Glass | El material: The window is made of glass. | Un vaso para beber: I drank a glass of water. |Iron | El metal: Iron is a strong metal. | Una plancha para la ropa: I need an iron. |Experience | Conocimiento acumulado: She has much experience. | Un evento específico: It was a great experience. |Time | El concepto abstracto: Time flies. | Ocasiones o momentos: I've been there three times. |Hair sigue exactamente esta misma lógica: la cabellera es materia, una hebra suelta es un objeto.hairs para referirme al vello corporal?body hair (incontable). Sin embargo, si te refieres a pelos individuales que crecen en un lugar específico (como un lunar o el pecho), puedes usar hairs.hair.hair y fur?Fur se refiere al pelaje denso de los animales (como un conejo o un oso). Hair se usa para humanos y para animales con pelo más largo o similar al humano (como algunos perros o caballos). Curiosamente, fur es casi siempre incontable.furs a menos que hablemos de diferentes tipos de pieles en la industria de la moda.many hairs?separado, sigue siendo su cabellera. Debes decir He has very curly hair. El uso de many obligaría a usar hairs, y como ya vimos, eso suena a que puedes contar cada pelo individualmente, lo cual no es el caso.hairs?to split hairs. Significa buscarle tres pies al gatoo discutir por detalles insignificantes. La imagen es la de alguien intentando dividir una hebra de cabello individual (algo casi imposible y ridículo), lo que refleja la minuciosidad de la discusión.
