Overview
unreal comparisons (comparaciones irreales). Para nosotros, los hispanohablantes, este concepto nos resulta extrañamente familiar pero técnicamente exigente cuando intentamos replicarlo con la precisión que exige la maestría en inglés.as if y as though, estamos entrando en el mundo de la percepción frente a la realidad. No estamos afirmando hechos; estamos describiendo cómo se siente, parece o suena una situación, basándonos en una premisa que sabemos (o sospechamos) que es falsa. Imagínate que estás viendo una serie en Netflix y un personaje actúa con una arrogancia desmedida, como si fuera el dueño de la ciudad, cuando en realidad es un estafador.as if y as though.as if he had been through a war (como si hubiera pasado por una guerra). El dominio de los saltos temporales (tense shifts) en estas cláusulas es lo que separa a un usuario avanzado de un verdadero experto.as if y as though reside en la creación de una hipótesis comparativa. La clave para entender esto es lo que los lingüistas llaman psicología de la distancia. Cuando usamos un tiempo verbal en pasado para hablar del presente, no estamos hablando del tiempo cronológico, sino de la distancia que hay entre nuestras palabras y la realidad objetiva.unreal past. Esta estructura se divide fundamentalmente en dos escenarios según la temporalidad de la comparación irreal:- 1Presente o Futuro Irreal: Usamos el
simple pastpara indicar que la situación descrita en la cláusula subordinada no es real en el momento actual. Por ejemplo:He spends money as if he owned a bank. (Gasta dinero como si fuera dueño de un banco). La realidad es que no es dueño de un banco, por lo tanto, el pasadoownedmarca esa irrealidad. - 2Pasado Irreal: Si nos referimos a algo que no sucedió en el pasado, pero cuya apariencia estamos describiendo, utilizamos el
past perfect. Ejemplo:She looked at me as though I had betrayed her. (Me miró como si la hubiera traicionado). La implicación es que no la traicioné, pero su mirada sugería que eso era lo que ella sentía o percibía.
As if o As though?as though tiene un toque ligeramente más formal y elegante.as though te da ese edge de sofisticación. En una conversación de WhatsApp con amigos, as if es más común.wereto be, el inglés académico prefiere were para todas las personas en situaciones irreales. Aunque en el lenguaje cotidiano oirás as if he was, para un nivel C2, lo correcto y esperado es as if he were.If I were you...).as if / as though + [Sujeto] + [Verbo en Tiempo Irreal]He acts | as if | he were famous | He is not famous. |You look | as though | you saw a ghost | You didn't actually see a ghost right now. |It feels | as if | it were summer | It is actually winter or cold. |She speaks | as if | she had lived there | She never lived there. |They greeted us | as though | we had met before | We had never met before. |He cried | as if | his world had ended | His world didn't actually end. |as if estamos hablando de algo falso. A veces, la comparación es muy probable o basada en evidencia real. En estos casos, no usamos el pasado irreal, sino el tiempo verbal que corresponda a la realidad (indicativo).- Unreal:
He looks as if he were a millionaire.(Sabemos que es pobre, se ha disfrazado). - Real/Probable:
He looks as if he is a millionaire.(Viste ropa cara, tiene un coche de lujo; es muy probable que realmente lo sea).

My aunt was dancing as though she had won the lottery. No es que creas que ganó la lotería, sino que su nivel de alegría solo es comparable a ese evento hipotético. El past perfect (had won) sitúa la supuesta ganancia antes del momento del baile.- En críticas indirectas o cortesía:

You are presenting the case as if the facts didn't matter.didn't crea una capa de distanciamiento que hace que la crítica sea más analítica y menos personal.- Para describir estados sensoriales:
The air felt as though it hadn't been disturbed for centuries. Aquí utilizas el lenguaje para evocar una sensación profunda, casi poética, que es fundamental para la fluidez de nivel C2.- Situaciones de incredulidad o ironía:
You’re telling the story as if I had never been there. Estás usando el past perfect para recordarle a la otra persona que tú *sí* estuviste allí y que su versión es puramente imaginaria.como si en el habla muy coloquial (aunque es incorrecto), pero en inglés, si la situación es irreal, debes usar el pasado.- Incorrecto:
He behaves as if he is the king. - Correcto:
He behaves as if he were the king. - Por qué ocurre: Tendemos a pensar en el presente porque la persona se está comportando así *ahora*. Pero recuerda: el pasado en inglés marca la irrealidad, no el tiempo.
Past Perfect para eventos pasadosas if, sin importar si la hipótesis se refiere a un momento anterior.- Incorrecto:
She looked as if she saw a ghost.(Si se refiere a algo que pasó antes de mirarme). - Correcto:
She looked as if she had seen a ghost. - Por qué ocurre: En español, a veces simplificamos y decimos
Parecía como si vio un fantasma
, pero gramaticalmente, el pluscuamperfecto (hubiera visto) es el equivalente necesario para mantener la jerarquía temporal.
like en contextos formalesHe looks like he's crazy. En el lenguaje hablado informal, like ha reemplazado casi totalmente a as if. Sin embargo, en el nivel C2, el uso de like seguido de una cláusula completa se considera un rasgo de lenguaje poco sofisticado o informal.- Evita:
It felt like I was dreaming.(Informal). - Prefiere:
It felt as though I were dreaming.(C2 Mastery).

Preguntas frecuentes (8)
Yes, in informal spoken English, `was` is very common (e.g., 'He acts as if he was rich'). However, for exams and formal writing, `were` is preferred.
There is no difference in meaning. `As though` is slightly more formal and more common in British literature.
Use the Present Simple when the situation is likely to be true (e.g., 'It looks as if it is raining').
In casual speech, yes. In formal writing, no. `As if` is a conjunction that introduces a clause, while `like` is a preposition.
