Subjunctive with Cuando and Future Situations

Spanish uses the subjunctive after certain time expressions when referring to future events that have not yet occurred. One of the most common expressions is cuando. In this module, you will learn how the subjunctive appears after cuando when talking about future situations.

Saldrán cuando termine la reunión. – They will leave when the meeting ends.
