Conditional tense in Spanish.How & when to use it.

The conditional tense, called the condicional simple in Spanish, describes an action or situation that would happen under a condition or in an imagined situation. It is also used to express English would, as well as polite requests, wishes, advice, and the future viewed from a past point of view.

Spanish forms the conditional with an infinitive or an irregular stem plus one set of endings. Unlike English, the subject is often clear from the verb ending, so subject pronouns can be omitted.

The conditional tense, or condicional simple, is used to express hypothetical results, polite requests and offers, wishes, advice, and events that were future from a past point of view.

Politeness

Use it to make requests or offers softer and more respectful.

• ¿Podrías ayudarme? — Could you help me?
• Me gustaría un café, por favor. — I would like a coffee, please.

Hypothetical situations

Use it for the result of a condition that is unlikely, imagined, or contrary to present circumstances. The condition commonly uses the imperfect subjunctive.

• Si tuviera dinero, viajaría por el mundo. — If I had money, I would travel the world.

Future in the past

Use it for an event that was still in the future when viewed from a past time.

• Dijo que llegaría a las nueve. — He said that he would arrive at nine.

Desires and dreams

Use it to express what you would like to do or what you wish would happen.

• Me gustaría visitar España algún día. — I would like to visit Spain someday.

Suggestions

Use it with verbs such as deber to give polite advice or make a gentle recommendation.

• Deberías hablar con ella. — You should talk to her.

The conditional is common in both speech and writing, especially when speakers want to sound polite or describe possibilities.

For regular verbs, add the conditional endings directly to the complete infinitive. The endings are the same for -ar, -er, and -ir verbs.

For example, the complete infinitive remains before the ending: vivir → viviría — to live → I would live.

Irregular stems

Some verbs change their stem, but they take the same conditional endings:

• decir → dir-
• hacer → har-
• poder → podr-
• poner → pondr-
• querer → querr-
• saber → sabr-
• salir → saldr-
• tener → tendr-
• venir → vendr-

For instance: tendría — I would have.

The condicional simple expresses actions that would happen under certain conditions. Regular verbs keep their complete infinitive and add the conditional endings; irregular verbs use a changed stem with those same endings.

Regular verbs

Regular -ar verb: hablar (to speak)

Regular -er verb: comer (to eat)

Regular -ir verb: vivir (to live)

Irregular verbs

Irregular verbs change the stem but use the regular endings. Common examples include decir → dir-, hacer → har-, poder → podr-, poner → pondr-, querer → querr-, saber → sabr-, salir → saldr-, tener → tendr-, and venir → vendr-.

Example: tener (to have)

Some words and expressions commonly appear with the conditional or with the condition that explains it. They are useful signals, but they do not automatically require the conditional.

• A possibility
• A hypothetical situation
• A polite request

si (if)

In hypothetical conditions, si is commonly followed by the imperfect subjunctive, while the result clause uses the conditional.

Si tuviera tiempo, iría al cine. — If I had time, I would go to the movies.

pero (but)

Pero means “but” and can introduce a contrast in an imagined situation; it does not itself trigger the conditional.

Me encantaría viajar, pero no tengo dinero. — I would love to travel, but I do not have money.

quizás or tal vez (maybe or perhaps)

These expressions show uncertainty. They can occur with the conditional when referring to a hypothetical or reported possibility, although other moods and tenses are also possible.

Quizás vendría a la fiesta si la invitaran. — Maybe she would come to the party if they invited her.

gustar (to like)

Gustar in the conditional is common for polite requests and wishes.

Me gustaría un café, por favor. — I would like a coffee, please.

querer (to want)

The conditional of querer can express a polite intention or request.

Querría saber la respuesta. — I would like to know the answer.

deber (should or ought to)

The conditional of deber gives soft advice or expresses a recommendation.

Deberías estudiar más. — You should study more.

poder (could)

The conditional of poder can indicate hypothetical ability, possibility, or a polite offer.

Podría ayudarte mañana. — I could help you tomorrow.

Tip: Treat these words as useful context clues rather than automatic triggers. Check whether the sentence expresses a hypothesis, possibility, politeness, advice, or a future event viewed from the past.
