You’re about to say what you would do, ask with tact, and describe future possibilities from a past viewpoint. Start with the first unit, where volvería shifts a story into an imagined future.

The simple conditional presents an action as future from a point in the past. The action does not occur at the moment of speaking; it remains in an imagined, anticipated, or pending zone within a past narrative. That is why it appears often in news, narratives, and thoughts referring to the past: . From that past moment, indicates something that was still to come. It also serves to project a consequence that depended on another situation: . The central value is this look ahead, but situated outside the present.

The regular conditional is formed with the complete infinitive + the endings . Nothing is removed from the infinitive: + gives ; + gives ; + gives . The complete base remains the same for all regular verbs. The endings are the same as in Verb tense conjugations, because this tense shares the same group of persons and the same order of personal forms. Thus all the persons are: . In regular verbs, the marker of the conditional always appears at the end of the infinitive.

The conditional softens requests, suggestions, and wishes. Instead of sounding direct, it leaves room for the other person and reduces the force of the sentence. That is why it is common in questions and offers such as , and . In a request, the speaker does not order; they propose. In a suggestion, they do not impose; they invite. In a wish, they do not state an immediate need; they express a preference delicately. The verb can stand alone or be accompanied by expressions such as , and when a subordinate clause appears.

Conditional for speaking politely
UsageExplanation
☕Polite requestWe use the conditional to make a request softer and more polite.
🗺️Gentle suggestionWe use the conditional to give an idea without sounding forceful.
🎶Polite wishWe use the conditional to express a wish with tact and delicacy.

The conditional also expresses an assumption about something that is not known with certainty. The speaker deduces or imagines a possibility based on signs, rumors, or logic. In the present, it usually indicates a conjecture: ; . In the past, it can refer to a hypothetical explanation: ; . Here the conditional does not mark future time, but rather distance from certainty. The sentence presents the idea as probable, not confirmed.

Conditional for supposing or calculating
UsageExplanation
🏠Present suppositionWe use the conditional to state a conjecture about the present when we are not sure.
🌧️Past suppositionWe use the conditional to imagine a probable cause in the past.
📦Approximate calculationWe use the conditional to give an estimate that is not exact.

In sentences with , the conditional appears in the consequence of a hypothetical situation. The usual structure is : . The part with presents an imagined condition; the conditional names the result that would depend on that condition. It is also used for less real consequences in narratives and comments: . The relationship between the two parts is clear: a possible or unreal situation in and a consequence in the conditional. For the complete combination with less probable scenarios or scenarios contrary to reality, the explanation of Expressing hypotheses and politeness together with Conditional with si is also useful.

Conditional in sentences with if
Idea
✈️In a sentence with if and a hypothetical condition, the consequence usually goes in the simple conditional.
☂️The part with if presents the condition, and the other part presents the imagined result.
🚲We do not use the conditional in both parts when we are talking about a normal hypothesis.

When the condition is contrary to reality, the simple conditional appears with the imperfect subjunctive. The form expresses something that does not happen now or that did not happen before, but that is imagined as another possibility. The structure is : ; , although here another, more advanced past form already comes in. In the simple conditional, the focus is on the imagined consequence: , . The imperfect subjunctive places the condition far from reality; the conditional presents the result of that alternative reality. The relationship between both forms is the basis of many hypotheses in Spanish.

Conditional with imperfect subjunctive
Idea
🪜To talk about an unreal situation, we use if with the imperfect subjunctive and the consequence in the simple conditional.
🪽This combination serves to express something contrary to current reality.
🗺️We also use it to imagine a condition very unlikely.

Some verbs add to a special stem. The most common are and . Their forms are ; ; . The change is not in the endings, but in the stem. Instead of , and , , and appear. These forms are recognized because they retain in all persons and do not follow the regular model of infinitive + ending.

Other verbs change their stem before adding the conditional endings. gives ; gives ; gives ; gives . The key is that the stem does not match the complete infinitive. In , the disappears and appears. In , the base form changes to . In and , is added to the stem. These irregularities are memorized as complete blocks, because the ending remains the same as in regular verbs.

The conditional and the future share a similar form, but they do not express the same thing. The simple future places the action as forthcoming from the present: . The conditional places the action as future from a past point or as an imagined consequence: ; . In form, the future uses the same endings as the conditional, but with a different base: versus . In several irregular verbs, the stem also changes differently: versus , versus . The sentence and context make it possible to distinguish whether the action is presented as a promise or prediction, or as a hypothesis and temporal distance.

Conditional versus future
UsageExplanation
🌙HypothesisWe use the conditional for an action imagined or dependent on a condition.
🛒PredictionWe use the future for an action more certain or expected.
🕰️Temporal distanceThe conditional usually views the action from a past or hypothetical point.

The conditional and the imperfect may seem similar, but they fulfill different functions. The imperfect describes habits, background scenes, and past situations: ; . The conditional does not describe a habit; it presents a possible consequence, a conjecture, or a polite form: ; ; . In a narrative, the imperfect paints the context and the conditional advances a dependent or imagined idea. If the sentence talks about what happened frequently or what something was like in the past, use the imperfect. If it talks about what would have happened, could happen, or is requested gently, use the conditional.

🚲We do not use the conditional to describe a past habit.
