Spanish cuando: indicative or subjunctive?
Vocalyra teaching team · Last updated:
Spanish cuando does not automatically require the subjunctive. The verb mood depends on whether you describe a known event or a future situation not yet realized.
Known events and habits use the indicative
Use the indicative when cuando introduces a habitual action or a past event presented as fact: Cuando llego a casa, preparo la cena means When I get home, I make dinner. Cuando llegué, ella ya estaba allà means When I arrived, she was already there. Both describe events the speaker treats as real. The form llego is present indicative; llegué is preterite indicative. Do not assume that every sentence about the future uses a special tense: context determines whether the action is still pending or part of a repeated routine. Listening for time markers helps you decide.
Future events normally take the subjunctive
When cuando introduces an event that has not yet occurred, Spanish generally uses the present subjunctive: Cuando llegues, llámame means When you arrive, call me. Notice that English uses present arrive for future reference, but Spanish uses llegues. Another example is Cuando tenga tiempo, estudiaré, When I have time, I will study. Do not write Cuando llegarás, llámame in standard Spanish for this meaning. The main clause may contain a future tense or an imperative; the subordinate clause after cuando expresses the pending event with subjunctive. The speaker does not assert that it has already happened.
A reliable contrast for English speakers
English says When I arrive tomorrow, I'll text you, using a present form even though tomorrow is future. Spanish says Cuando llegue mañana, te escribiré. This mismatch is easy to overlook because both sentences sound natural in their own language. Compare Cuando trabajo, escucho música, a routine, with Cuando trabaje mañana, escucharé música, a future situation. The spelling difference between trabajo and trabaje is small, but it signals a change in how the event is presented. Keep the time reference and the verb form together when you practise.
Make your own two-column timeline
Draw two columns labelled routine or fact and future pending event. Put three real habits in the first column using cuando with the indicative. In the second, write three upcoming events and use the subjunctive after cuando. Read each pair aloud, then change the time expression and see whether the mood should change. For example, Cuando vuelvo los viernes contrasts with Cuando vuelva el viernes. This method trains meaning first and conjugation second, reducing the temptation to choose a mood based only on the word cuando.
| Example | Meaning |
|---|---|
| Cuando llego, cocino. | When I arrive, I cook. |
| Cuando llegué, llamó. | When I arrived, he/she called. |
| Cuando llegues, llama. | When you arrive, call. |
| Cuando tenga tiempo, iré. | When I have time, I will go. |
What happens when you add todavĂa no?
The time expression todavĂa no (not yet) can remind you that a future event has not happened, but it does not automatically determine the mood by itself. Compare Cuando tengo vacaciones, visito a mi familia: a recurring habit. Now say Cuando tenga vacaciones este verano, visitarĂ© a mi familia: a particular future event. The subjunctive works because the visit and the holiday remain pending in the speaker’s framing. Use meaning and context together; do not mechanically choose subjunctive whenever a sentence contains mañana.
Do not confuse cuando with the question cuándo
The accented cuándo appears in questions and many indirect questions: ¿Cuándo llegas? and No sé cuándo llegarás. The unaccented conjunction cuando introduces a time clause: Cuando llegues, llámame. These constructions are different. A direct future question can use the future indicative, as in ¿Cuándo llegarás?, while an ordinary pending-event clause generally uses Cuando llegues. Spelling, punctuation and clause function all help you choose the correct form.
