Explicación
El condicional irreal de pasado tiene la forma «If + sujeto + had + participio pasado, sujeto + would/could/might + have + participio pasado» y es la expresión con la que se imagina una situación contraria a un hecho pasado ya consumado.
A. Forma — If + had + p.p., would/could/might + have + p.p.
En el irreal de pasado se emparejan had + participio pasado (pasado perfecto) en la cláusula con if y would/could/might + have + participio pasado en la oración principal. Aprende de una pieza la fórmula If + had + p.p., would have + p.p..
| Estructura | Matiz | Ejemplo |
|---|---|---|
| If + had p.p., would have p.p. | lo habría hecho | If I had known, I would have called. |
| If + had p.p., could have p.p. | habría podido hacerlo | If she had tried, she could have won. |
| If + had p.p., might have p.p. | quizá lo habría hecho | If we had left earlier, we might have caught it. |
- If I had woken up earlier, I wouldn't have been late. (Si me hubiera despertado antes, no habría llegado tarde.)
- If they had invited us, we would have come. (Si nos hubieran invitado, habríamos ido.)
- If she had studied medicine, she could have become a doctor. (Si hubiera estudiado medicina, habría podido ser médica.)
- If I had taken the bus, I might have arrived on time. (Si hubiera cogido el autobús, quizá habría llegado a tiempo.)
B. Sentido — lo contrario del pasado
Como el irreal de pasado es la expresión con la que se imagina al revés algo que ya ocurrió, detrás de la frase se esconde siempre la implicación «(en realidad no fue así)». Se usa a menudo para transmitir emociones como arrepentimiento, lástima, alivio o reproche.
| Matiz | Ejemplo | Implicación oculta |
|---|---|---|
| Arrepentimiento | If I had studied more, I would have passed. | no estudió y no aprobó |
| Lástima | If we had left earlier, we would have caught the flight. | salieron tarde y lo perdieron |
| Alivio | If I hadn't worn a helmet, I would have been hurt. | lo llevó y no se hizo daño |
| Reproche | If you had told me, I would have helped. | no lo dijo y no pudo ayudar |
- If I hadn't slept in, I would have caught the bus. (Si no me hubiera quedado dormido, habría cogido el autobús.)
- If he had apologized, she would have forgiven him. (Si él se hubiera disculpado, ella lo habría perdonado.)
- If I had brought an umbrella, I wouldn't have gotten wet. (Si hubiera traído paraguas, no me habría mojado.)
- If she had told me the truth, I wouldn't have been upset. (Si me hubiera dicho la verdad, no me habría enfadado.)
C. Visualizar el tiempo — real vs. imaginado
Como el irreal de pasado mira «un punto del pasado» en el eje temporal y da la vuelta a la decisión de entonces, el matiz cobra vida si aprendes con nitidez el contraste entre lo que ocurrió de verdad y lo imaginado.
| Real (hecho) | Imaginado (lo contrario) |
|---|---|
| I didn't study. → I failed. | If I had studied, I would have passed. |
| She left late. → She missed the train. | If she had left early, she wouldn't have missed it. |
| We didn't know. → We didn't help. | If we had known, we would have helped. |
| He didn't apologize. → She stayed angry. | If he had apologized, she would have forgiven him. |
- If I had taken the job, I would have moved to New York. (Si hubiera aceptado el trabajo, me habría mudado a Nueva York.)
- If she hadn't forgotten her passport, she would have boarded the plane. (Si no se hubiera olvidado el pasaporte, habría embarcado en el avión.)
- If we had checked the weather, we wouldn't have gone hiking. (Si hubiéramos consultado el tiempo, no habríamos ido de excursión.)
- If he had saved, he could have bought a car. (Si hubiera ahorrado, habría podido comprarse un coche.)
Ideas clave
- 1Lo esencial es que el irreal de pasado, al imaginar al revés un hecho pasado ya consumado, esconde siempre la implicación de que en realidad no se hizo así. (ej.: If I had studied, ... → en realidad no estudió)
- 2La clave de la forma es la estructura doble: had + participio pasado en la cláusula con if y would/could/might + have + participio pasado en la oración principal. (ej.: If I had known, I would have called.)
- 3Dentro de la cláusula con if del irreal de pasado nunca se usa would have ni will have, solo had p.p.: es el punto en el que más a menudo se falla. (ej.: If I had known, ...)
- 4En la oración principal, would/could/might solo cambian el matiz y detrás va obligatoriamente have + participio pasado: respeta esta forma. (ej.: I would have gone / could have gone)
- 5En la conversación es habitual reducir de forma natural would have / could have a would've / could've al pronunciar. (ej.: I would've gone. / He could've helped.)
