One of the most common jobs of the conditional is to describe hypothetical situations — things that would happen under conditions that are imagined, unlikely, or contrary to reality. In English this is almost always signaled by the word "would."
With si-clauses (type 2 conditionals)
The classic pattern pairs an imperfect subjunctive in the si-clause with a conditional in the result clause. These sentences describe situations that are not true right now but that we are imagining.
Structure: Si + imperfect subjunctive, conditional.
Si hablara chino, viajaría a Shanghái.
If I spoke Chinese, I would travel to Shanghai.
Notice that neither half of the sentence is in the present. The speaker doesn't have the money, doesn't speak Chinese, and isn't rich — the whole sentence lives in an imagined world.
Expressing wishes with gustar
The conditional of gustar — me gustaría, te gustaría, le gustaría, nos gustaría, les gustaría — is the standard way to say "I would like." It softens a raw quiero and is the default for stating preferences politely.
Me gustaría viajar a Costa Rica algún día.
I would like to travel to Costa Rica someday.
¿A ustedes les gustaría venir a cenar el viernes?
Would you all like to come over for dinner on Friday?
Talking about preferences and dreams
Beyond gustar, any verb can express a hypothetical preference. The speaker is not committing to the action — they are imagining it.
Yo preferiría vivir en el campo, no en la ciudad.
I would prefer to live in the countryside, not the city.
What would you do?
Asking ¿qué harías? is a natural way to invite someone to imagine themselves in a situation.
Yo viajaría por el mundo y donaría una parte a caridad.
I would travel the world and donate part of it to charity.
Quick comparison
| Reality | Hypothetical |
|---|---|
| Tengo dinero, compro una casa. | Si tuviera dinero, compraría una casa. |
| No hablo chino, no viajo a Shanghái. | Si hablara chino, viajaría a Shanghái. |
| No soy rica, trabajo los domingos. | Si fuera rica, no trabajaría los domingos. |
The right column pulls the whole sentence into an imagined world, and the conditional is the verb form that marks the imagined outcome.
One more note on word order
The si-clause and the result clause can appear in either order. When the si-clause comes first, a comma separates the two halves; when the result clause comes first, no comma is needed.
Si fuera tú, aceptaría la oferta sin pensarlo dos veces.
If I were you, I would accept the offer without thinking twice.
Te escribiría una canción si supiera tocar la guitarra.
I would write you a song if I knew how to play the guitar.
Both orders are equally natural, and you will hear both in everyday conversation.
