What is a real conditional sentence?
A real conditional sentence expresses a condition that is possible or likely to happen and the consequence that follows. In Spanish, these sentences often use the conjunction si followed by a verb in the present tense and a main clause in the present, future, or imperative. The idea is that the condition can realistically occur, so speakers use straightforward tenses rather than the subjunctive for unlikely or contrary-to-fact scenarios.
Basic structure
The most common structure for real conditions is:
Si + present indicative, + present indicative / future / imperative.
Example patterns:
Si + present, + present: Si estudio, aprendo.
Si + present, + future: Si estudio, aprobaré.
Si + present, + imperative: Si necesitas ayuda, llámame.
Detailed breakdown: Si mi hijo viene
Take the phrase Si mi hijo viene. The verb venir is in the present indicative viene (third person singular). This sets up a realistic condition: my child might come. What follows depends on the speaker’s intention: describe a current result, predict the future, or give an instruction or suggestion.
Result in the present
When the main clause uses the present, it expresses what typically happens when the condition is met or a general truth.
Si mi hijo viene, comemos juntos.
This means that whenever my child comes, we eat together. The situation is habitual or a general outcome of the condition.
Result in the future
Using the future tense for the main clause indicates a probable outcome connected to the condition.
Si mi hijo viene, cenaremos en casa.
Here the speaker predicts that if the child comes, they will have dinner at home. The condition is realistic and the future expresses intention or prediction.
Imperative for instructions or invitations
The main clause can be an imperative, creating an instruction, offer, or invitation contingent on the condition.
Si mi hijo viene, pon la mesa.
This instructs someone to set the table if the child arrives.
Verb tense rules and common combinations
Real conditionals rely mainly on the present indicative in the si clause. The choice of tense in the main clause changes the nuance.
Present + present
Used for habitual actions and general truths.
Example: Si mi hijo viene, hablamos por teléfono.
Meaning: When my son comes, we talk on the phone (habitual or immediate result).
Present + future (simple future)
Used to express likely future consequences or promises.
Example: Si mi hijo viene, lo presentaré a tus amigos.
Meaning: If he comes, I will introduce him to your friends.
Present + imperative
Used to give instructions, commands, or requests conditional on something happening.
Example: Si mi hijo viene, asegúrate de que tenga comida.
Meaning: If he comes, make sure he has food.
Present + present perfect
The present perfect in the main clause can indicate a result completed in the recent past when the condition holds.
Example: Si mi hijo viene, ya hemos comprado todo.
Meaning: If he comes, we will already have bought everything (the planning implies completion by that event).
Word order and punctuation
Spanish allows the si clause to come first or second. When the si clause comes first, separate it from the main clause with a comma. When the main clause comes first, no comma is needed.
Si mi hijo viene, iremos al parque.
Iremos al parque si mi hijo viene.
Emphasis and inversion
Placing the si clause first slightly emphasizes the condition. Putting the main clause first emphasizes the consequence.
Compare: Si mi hijo viene, cocinaremos paella.
Cocinaremos paella si mi hijo viene.
Common verbs and expressions used with Si mi hijo viene
Real condition sentences often use verbs of movement, arrangement, decision, or emotion because arrival triggers plans or feelings.
Examples:
Si mi hijo viene, preparo la habitación.
Si mi hijo viene, llamo a la familia.
Si mi hijo viene, estaré feliz.
Si mi hijo viene, tendremos que comprar más comida.
Modal verbs and probability
When expressing probability, Spanish speakers may use poder or deber in the main clause.
Example: Si mi hijo viene, puede quedarse.
Meaning: He can stay if he comes.
Negative conditionals with Si mi hijo viene
Negating the condition or the consequence is simple: add no before the verb you want to negate.
Negative condition: Si mi hijo no viene, cancelaremos la cena.
Negative consequence: Si mi hijo viene, no saldremos temprano.
Nuance: no in the si clause versus no in the main clause
Putting no in the si clause makes the condition about the absence of the event. Putting no in the main clause denies the consequence even if the condition occurs.
Example pair: Si mi hijo no viene, me quedaré solo.
Si mi hijo viene, no me quedaré solo.
Contrast with unreal and improbable conditionals
Real conditionals use the present indicative in the si clause. Unreal or hypothetical situations require the imperfect subjunctive or pluperfect subjunctive. Knowing the difference helps avoid common mistakes.
Real: Si mi hijo viene, lo veré.
Unreal (contrary-to-fact): Si mi hijo viniera, lo vería.
The unreal version suggests the speaker thinks the child probably will not come, while the real version treats the arrival as possible.
When to use the subjunctive
Use the subjunctive when the condition is unlikely, wished for, or contrary to reality. Beginners should remember: present indicative = real/possible; subjunctive = hypothetical/unreal.
Real-life scenarios and examples
Here are practical contexts showing how Si mi hijo viene appears naturally in speech or writing.
Family plans:
Si mi hijo viene este fin de semana, iremos a la playa.
Making arrangements:
Si mi hijo viene, tengo que preparar una cama extra.
Expressing feelings:
Si mi hijo viene, me pongo muy contento.
Giving instructions:
Si mi hijo viene, dile que pase por la oficina antes de ir a su habitación.
Predicting something probable:
Si mi hijo viene, probablemente conocerá a los nuevos vecinos.
Everyday vocabulary with these sentences
Useful verbs: venir, llegar, quedarse, llamar, preparar, traer, ver, encontrar, cocinar, invitar. Useful nouns: fin de semana, cena, dormitorio, amigos, vecinos, comida, visita.
Politeness and formality
Real conditional sentences are neutral in tone. For polite requests related to the condition, use conditional forms or polite imperatives in the main clause.
Example: Si mi hijo viene, ¿podrías esperar un momento?
This is polite and uses the conditional auxiliary in a question. For commands, soften with por favor: Si mi hijo viene, por favor avísame.
Common mistakes and tips
1. Avoid using the subjunctive in real conditions. Use the present indicative in the si clause for realistic possibilities.
Incorrect: Si mi hijo venga, llamo.
Correct: Si mi hijo viene, llamo.
2. Keep verb agreement correct. Mi hijo takes third person singular forms: viene, llegará, está.
3. Watch word order and punctuation. Use a comma when the si clause comes first.
4. Distinguish between likely and unlikely scenarios. Use the subjunctive only when the situation is hypothetical or contrary to fact.
Cultural notes and conversational use
Spanish speakers often use conditional sentences to coordinate family logistics, show concern, or express plans. The simple structure makes it ideal for quick decisions: Si mi hijo viene is frequently heard when discussing visits by children or relatives. In many Spanish-speaking households, plans change based on arrivals, so these constructions are very common in everyday conversation.
Regional variations are minimal for this structure; the key differences appear in vocabulary or formality rather than grammar. In casual talk, contractions or dropped words may appear, but the si + present pattern remains the same.
Useful variations and expansions
You can expand the si clause with time or condition phrases to give more context.
Si mi hijo viene mañana por la tarde, cenaremos temprano.
Si mi hijo viene con amigos, tendremos que preparar más comida.
Use quantifiers and probability markers like probablemente or tal vez in the main clause to soften predictions.
Si mi hijo viene, probablemente iremos al cine.
Conclusion
The phrase Si mi hijo viene introduces realistic and possible conditions in Spanish. Use the present indicative in the si clause and pair it with present, future, or imperative in the main clause depending on the nuance you want. Remember the difference between real and unreal conditionals: present = possible, subjunctive = hypothetical. With practice, these structures become natural and indispensable for everyday conversation about plans, instructions, and likely outcomes.
