Enfatizando con "It" (Oraciones Hendidas con "It")

Las estructuras 'It-clefts' (
It is/was... that/who
) son tu arma secreta para dar énfasis y claridad a la información específica. ¡Genial para destacar!

Grammar Rule in 30 Seconds

Use 'It-Clefts' to shine a spotlight on one specific part of your sentence for maximum emphasis.

  • Start with 'It' followed by the verb 'be' in the correct tense: 'It was...'
  • Place the information you want to emphasize immediately after 'be': 'It was the manager...'
  • Connect the rest of the sentence using 'that' or 'who': '...who called me.'
It + be + [Focus Point] + that/who + [Rest of Sentence]

Overview

¿Alguna vez has sentido que tus frases son un poco aburridas? A veces quieres señalar con el dedo la parte más importante. Imagina que estás en una fiesta.
Un amigo dice: Peter compró la pizza. ¡Pero tú sabes que en realidad fue Sarah! Gritas:
¡No, fue Sarah quien compró la pizza!
.
Esto es un it-cleft. Es como un foco de luz en un escenario. Mueve el interés de toda la frase a una sola persona o cosa.
En la universidad o el colegio, lo usamos para ser muy claros con los hechos. Pero no es solo para profesores; lo usas todos los días cuando envías mensajes a tus amigos o discutes sobre películas. ¿Por qué decir Me encanta esta canción cuando puedes decir Es esta canción la que me encanta?
Añade un poco de drama y estilo. Y lo más importante: asegura que nadie se pierda tu punto de vista. Piensa en ello como el botón de negrita para tu voz.

Word Order Rules

Construir una frase it-cleft es como hacer un sándwich. Necesitas capas específicas en un orden determinado.
  • Empieza con la palabra It.
  • Añade el verbo to be (is o was).
  • Coloca el Elemento Enfocado a continuación.
  • Añade la palabra that o who.
  • Termina con el resto de la frase.

How This Grammar Works

Funciona dividiendo una frase en dos partes. La parte 1 presenta a la estrella. La parte 2 da los detalles. En contextos académicos, es genial para definir causas. Ejemplo: Fue la investigación la que demostró la teoría. Le dice al lector:
¡Mira la investigación!
.

Fácil de confundir

Focusing with "It" (It-Clefts) vs Wh-Clefts

Learners mix up 'It was...' and 'What I want is...'.

Focusing with "It" (It-Clefts) vs Dummy 'It' (Weather/Time)

Focusing with "It" (It-Clefts) vs Relative Clauses

Errores comunes

Is my mom who cooks.

It is my mom who cooks.

You must include the dummy subject 'It'.

It is my mom cooks.

It is my mom who cooks.

You need a relative pronoun (who/that) to connect the clauses.

It my mom who cooks.

It is my mom who cooks.

Don't forget the verb 'be'.

It are my parents who cook.

It is my parents who cook.

The dummy 'It' always takes a singular verb 'is/was'.

It was the dog which barked.

In cleft sentences, 'that' is much more natural than 'which'.

It is yesterday that I saw him.

The tense of 'be' must match the time of the action.

It was me who did it.

It was I who did it. (Formal) / It was me who did it. (Informal)

In very formal English, use the subject pronoun, but 'me' is standard in conversation.

It was in London where I met her.

It was in London that I met her.

Use 'that' even for places in cleft sentences.

It was because the rain we stayed.

It was because of the rain that we stayed.

Ensure the prepositional phrase and the connector 'that' are both present.

It was my friends who they helped me.

It was my friends who helped me.

Do not repeat the subject pronoun in the relative clause.

It is the results which are surprising.

It is the results that are surprising.

Avoid 'which' in clefts for better stylistic flow.

It was him that I gave the book.

It was him that I gave the book to.

Don't forget the preposition if the focus is the object of a preposition.

It is only then when we understand.

It is only then that we understand.

Use 'that' instead of 'when' for time focus in clefts.

Preguntas frecuentes (8)

Technically yes, but it sounds very formal or slightly dated. In modern English, `that` or `who` is much more common in clefts.

In formal writing, `It is I` is grammatically 'correct', but in 99% of real-life situations, everyone says `It is me`.

In informal speech, yes: 'It was John called me.' But in writing, you should always include `that` or `who`.

Because the word 'cleft' means 'split'. You are splitting one simple sentence into two parts.

Yes! You can say, 'It will be the manager who makes the final decision.'

They are very similar. 'It-clefts' are slightly more emphatic and common in writing.

No, it-clefts usually focus on a noun or a prepositional phrase. For whole clauses, use a `Wh-cleft` (e.g., 'What happened was...').

Yes, it is equally common in all major dialects of English.
