Condiciones y posibilidades
Chapter Objectives
By the end of this chapter, you will be able to:
- Form and use si clauses with the present indicative to describe real or probable conditions.
- Pair a real or probable si clause with the present, the future, or a command in the result clause.
- Recognize and form the imperfect subjunctive of regular and common irregular verbs.
- Use si with the imperfect subjunctive together with the conditional to describe hypothetical or contrary-to-fact situations.
- Distinguish a condition presented as likely or open from a condition presented as unlikely, imagined, or untrue.
- Combine conditional sentences with the doubt, denial, and indefinite-antecedent patterns from Chapter 12 in connected speech and writing.
Communication Scenario
The volunteer program has found a few interested neighbors, but the committee still needs to plan for different outcomes. Camila is drafting notes for the next meeting: what the group will do if enough volunteers sign up, and what the group would do if the situation were different — for example, if the community center were bigger, or if more people had free time on weekends. English marks this contrast loosely with words like "if" and "would." Spanish marks it grammatically, through the choice of verb forms in the si clause and in the result clause.
- In English, compare If we get ten volunteers, we will start in March with If we had twenty volunteers, we would open a second location. Which sentence describes something the speaker considers likely? Which describes something more distant or imagined?
- Think of one real possibility and one imagined or unlikely possibility connected to a plan you are currently making. Notice how your English changes between the two.
Core Vocabulary: Condiciones, posibilidades y resultados
Purpose: to build vocabulary for describing conditions, results, and degrees of likelihood — the connectors and expressions that frame both real and hypothetical si clauses in this chapter.
| Palabra o expresión | Significado | Categoría |
|---|---|---|
| si | if | conector condicional |
| entonces | then, in that case | conector de resultado |
| en ese caso | in that case | conector de resultado |
| depender de | to depend on | condición |
| cumplirse | to come true, to be fulfilled | condición |
| la posibilidad | the possibility | sustantivo |
| el resultado | the result, outcome | sustantivo |
| probable | probable, likely | adjetivo |
| improbable / poco probable | improbable, unlikely | adjetivo |
| imaginar | to imagine | verbo |
| ojalá | if only, I wish (formulaic) | deseo (formulaico) |
| si tan solo | if only | deseo |
| lograr | to achieve, to manage to | verbo |
| ampliar | to expand, to enlarge | verbo |
| alcanzar | to reach, to be enough | verbo |
Ojalá is treated in this course as a formulaic expression of wish or hope. When followed by the imperfect subjunctive, it expresses a wish about something unlikely or contrary to the present reality; this use is glossed here for recognition and is not a required production pattern in this chapter.
Grammar: Condiciones reales o probables
Purpose: to describe a condition that the speaker treats as open, likely, or simply a fact-based possibility, and to state what will or may happen as a result.
When a speaker presents a condition as real, open, or likely to happen, Spanish uses the present indicative after si. The result clause can use the present, the future, or a command, depending on how the speaker wants to frame the outcome.
- Si + presente → futuro: Si diez personas se inscriben, empezaremos el programa en marzo.
- Si + presente → presente: Si alguien tiene dudas, siempre puede escribirle a Camila.
- Si + presente → mandato: Si tienes tiempo el sábado, ven a la reunión.
This pattern never uses the subjunctive in the si clause itself. The subjunctive you learned in Chapters 11 and 12 belongs to que clauses after triggers like recommendation, doubt, or an indefinite antecedent; ordinary real conditions with si keep the indicative.
Ejemplos:
- Si conseguimos suficiente dinero, ampliaremos el programa el próximo año. If we get enough money, we will expand the program next year.
- Si el comité aprueba el plan, empezamos la semana que viene. If the committee approves the plan, we start next week.
- Si no puedes venir el sábado, avísame antes del viernes. If you can't come on Saturday, let me know before Friday.
Práctica controlada:
- Completa: Si nosotros _____ (encontrar) más voluntarios, el proyecto _____ (poder) crecer.
- Completa: Si tú _____ (querer) participar, _____ (deber, mandato informal) hablar con Camila.
- Completa: Si tú _____ (tener) alguna duda, siempre _____ (poder) escribirme un mensaje.
- Escribe una oración con si + presente que describa una condición real de tu propia vida.
Grammar: Condiciones hipotéticas o contrarias a la realidad
Purpose: to form the imperfect subjunctive and to use it with si and the conditional to describe a situation the speaker treats as unlikely, imagined, or not currently true.
The imperfect subjunctive is formed from the ustedes/ellos form of the preterite. Remove -ron and add the imperfect subjunctive endings. All three verb groups (-ar, -er, -ir) follow the same endings.
| Infinitivo | Pretérito, ellos | Raíz | Yo | Nosotros |
|---|---|---|---|---|
| hablar | hablaron | habla- | hablara | habláramos |
| tener | tuvieron | tuvie- | tuviera | tuviéramos |
| ser / ir | fueron | fue- | fuera | fuéramos |
The nosotros form always carries a written accent on the vowel before the ending: habláramos, tuviéramos, fuéramos. This course presents the -ra forms as the default productive pattern; the alternative -se forms (hablase, tuviese) are recognition-only at this level, since they are more common in some formal, written, and Peninsular contexts than in everyday Latin American speech.
When a speaker presents a condition as unlikely, imagined, or contrary to present reality, the si clause uses the imperfect subjunctive and the result clause uses the conditional, which you first practiced in Chapter 7.
- Hipotético: Si tuviéramos más espacio, podríamos aceptar a más familias. (but we don't have more space right now)
- Contrario a la realidad: Si yo fuera el director, cambiaría el horario de las reuniones. (I am not the director)
Compare the two condition types directly: Si conseguimos el local, empezaremos en abril (a real possibility that is genuinely open) versus Si consiguiéramos un local más grande, empezaríamos antes (a situation the speaker treats as distant, difficult, or not currently true). The si clause never uses the conditional, and the result clause normally does not use the imperfect subjunctive; each half of the sentence has its own required form.
Ejemplos:
- Si tuviera más tiempo libre, ayudaría todos los sábados. If I had more free time, I would help every Saturday.
- Si el ayuntamiento nos diera más apoyo, el programa crecería más rápido. If the city government gave us more support, the program would grow faster.
- Si Don Rafael fuera coordinador, organizaría el calendario de otra manera. If Don Rafael were coordinator, he would organize the calendar differently.
Práctica controlada:
- Completa: Si nosotros _____ (tener) un presupuesto más grande, _____ (poder) contratar a alguien.
- Completa: Si Camila _____ (ser) menos optimista, no _____ (seguir) trabajando en esto.
- Completa: Si tú _____ (vivir) más cerca, _____ (venir) a todas las reuniones.
- Transforma la condición real en condición hipotética: Si conseguimos el local, empezamos en abril. → Si _____ el local, _____ en abril.
Model Dialogue
Camila and Don Rafael, now a more willing collaborator, talk through real and imagined scenarios for the program.
Listening Task
Ask your instructor, a partner, or a text-to-speech tool to read the following short passage aloud, twice. As you listen, identify each conditional sentence and mark whether it describes a real/probable condition or a hypothetical/contrary-to-fact condition.
"Si diez familias se inscriben antes del viernes, empezaremos el programa el mes que viene. Si conseguimos menos, empezaremos de todas formas, pero con menos actividades. Ojalá tuviéramos más voluntarios entrenados; si los tuviéramos, podríamos ofrecer más talleres. Y si algún día ampliáramos el programa a todo el barrio, necesitaríamos mucho más apoyo del ayuntamiento."
| Oración con si | Tipo (real/probable o hipotética/contraria a la realidad) |
|---|---|
| Si diez familias se inscriben... | ______ |
| Si conseguimos menos... | ______ |
| si los tuviéramos, podríamos ofrecer... | ______ |
| si algún día ampliáramos el programa... | ______ |
Reading Task
Reread the model dialogue above, then complete the following analysis independently or with a partner.
- Find every si clause in the dialogue and identify whether the verb is present indicative or imperfect subjunctive.
- For each si clause you found, identify the verb form used in the result clause, and explain why that combination is required.
- Explain why Don Rafael uses tuviéramos rather than tenemos when he talks about a bigger space.
- Find the formulaic expression of wish in the dialogue and explain what it suggests about whether the wish is currently true.
Writing Workshop: Planes y posibilidades
Write a short planning note (eight to ten sentences) for a project, event, or personal goal of your choice. Your note must include both real/probable conditions and hypothetical/contrary-to-fact conditions.
- Condición real, resultado futuro. Write at least one sentence using si + present indicative with a future-tense result.
- Condición real, resultado presente o mandato. Write at least one sentence using si + present indicative with a present-tense result or a command.
- Condición hipotética. Write at least one sentence using si + imperfect subjunctive with the conditional.
- Duda o antecedente indefinido. Include at least one sentence recycling a trigger from Chapter 11 or Chapter 12 (recommendation, doubt, denial, or an indefinite antecedent).
- Revisa. Check your draft against the checklist below before submitting it.
Lista de revisión:
- My note includes at least one real/probable condition and at least one hypothetical condition.
- I used the present indicative, not the subjunctive, in every real/probable si clause.
- I used the imperfect subjunctive in every hypothetical si clause and the conditional in its result clause.
- I formed the imperfect subjunctive correctly from the ellos preterite form.
- I recycled at least one trigger from Chapter 11 or Chapter 12 correctly.
- My accents, capitalization, and punctuation are correct throughout, including the accent on nosotros forms of the imperfect subjunctive.
Speaking Task
Práctica controlada
With a partner, take turns reading aloud the model dialogue, paying attention to which si clauses use the present indicative and which use the imperfect subjunctive.
Tarea comunicativa: Planes reales, planes imaginados
With a partner, discuss a shared plan (a trip, an event, a project). Each partner must state at least one real/probable condition about the plan and one hypothetical condition about how the plan would change under different circumstances.
Alternativa individual
If you are studying independently: record yourself describing two versions of a personal goal — what will happen if a realistic condition is met, and what would happen if an imagined or unlikely condition were true. Listen back and check your verb forms in both the si clause and the result clause.
Culture and Communication
Community and civic projects in many Spanish-speaking contexts are often described in terms of staged, conditional planning — what will happen with current resources, and what could happen with additional support from a local government, an institution, or a broader base of volunteers. This kind of layered planning language, moving between what is likely and what is hoped for, is common in neighborhood associations, school committees, and small nonprofit projects in many communities.
The -se form of the imperfect subjunctive (hablase, tuviese, fuese) is fully grammatical and appears regularly in formal writing, literature, and some spoken varieties, including in Spain. This course treats the -ra form as the default productive pattern across the Latin American production model, while the -se form remains recognition-only at this level.
Common Mistakes to Avoid
Error: Using the subjunctive in a real, open si clause — Si tengamos tiempo, iremos a la reunión.
Correction: A real or probable si clause takes the present indicative: Si tenemos tiempo, iremos a la reunión.
Error: Using the conditional inside the si clause of a hypothetical sentence — Si tendría más tiempo, ayudaría más.
Correction: The si clause uses the imperfect subjunctive, and the conditional stays in the result clause: Si tuviera más tiempo, ayudaría más.
Error: Dropping the accent on the nosotros form of the imperfect subjunctive — Si tuvieramos más espacio...
Correction: The nosotros form always carries a written accent: Si tuviéramos más espacio...

Answer Key
Grammar Practice — Condiciones reales
- encontramos / podrá
- quieres / debes
- tienes / puedes
- Model answer: Si me gradúo este año, buscaré trabajo en mi ciudad.
Grammar Practice — Condiciones hipotéticas
- tuviéramos / podríamos
- fuera / seguiría
- vivieras / vendrías
- Si consiguiéramos el local, empezaríamos en abril.
Listening Task
Si diez familias se inscriben — real/probable; Si conseguimos menos — real/probable; si los tuviéramos, podríamos ofrecer — hipotética; si algún día ampliáramos el programa — hipotética.
Reading Task — Model Analysis
1. Real/probable: Si diez personas se inscriben (presente), Si conseguimos solo cinco o seis (presente), Si necesitas ayuda esta semana (presente). Hipotéticas: Si tuviéramos el salón comunitario completo (imperfecto del subjuntivo), si el ayuntamiento nos diera más apoyo (imperfecto del subjuntivo), si algún día conseguimos ese salón más grande (presente, tratado como abierto por Don Rafael). 2. Real conditions pair with the future (empezaremos) or a command-like present; the hypothetical conditions pair with the conditional (podríamos, crecería), because the speaker treats the situation as unlikely or not currently true. 3. Don Rafael uses tuviéramos because the group does not currently have a bigger space; he is imagining a situation contrary to the present reality, which requires the imperfect subjunctive rather than the present indicative. 4. Ojalá tuviéramos también un espacio más grande is the formulaic wish; it suggests the group does not currently have that space, since ojalá with the imperfect subjunctive expresses a wish about something not presently true.
Chapter Review — Parte A
Model answer: conseguimos; empezaremos; necesitas; llama.
Chapter Review — Parte B
Model answer: tuviera; participaría; fuera; podría.
Chapter Review — Parte C
Model answer: A real condition uses the present indicative because the speaker treats it as genuinely open, such as Si llueve, cancelamos el evento. A hypothetical or contrary-to-fact condition uses the imperfect subjunctive and the conditional because the speaker treats it as unlikely or not currently true, such as Si yo tuviera más dinero, viajaría más.
Chapter Review — Parte D
Model answer: Dudo que el programa crezca mucho este año, pero si consiguiéramos más apoyo del ayuntamiento, podríamos aceptar a muchas más familias.
Looking Ahead
Lo que ya sabes
You can now describe real, open conditions with si and the present indicative, and you can describe hypothetical or contrary-to-fact conditions with the imperfect subjunctive and the conditional. Combined with Chapters 11 and 12, you can recommend, wish, doubt, deny, describe the uncertain, and now plan for different possible futures — a connected system for talking about what is likely, what is uncertain, and what is only imagined. Camila's committee can now plan realistically while still imagining what the program could become.
