Spanish Grammar Review

Mastering the subjunctive in adverbial phrases (and adverbial clauses) is one of the biggest milestones in achieving Spanish fluency. Adverbial clauses modify the main verb by telling us how, why, when, or under what conditions an action happens. In this quick review and quiz, we break down the essential rules of when to use the subjunctive mood versus the indicative mood in adverbial expressions. Conjunctions That ALWAYS Require the Subjunctive Some adverbial phrases introduce a condition, purpose, or hypothetical situation that hasn’t happened yet. These conjunctions always require the subjunctive mood when followed by a new subject and a conjugated verb. En caso de que (In case) Example: Llevaré mi paraguas en caso de que llueva. (I will bring my umbrella in case it rains.) Con tal (de) que (As long as / Provided that) Example: Te ayudaré con tal de que me acompañes al teatro esta noche. (I will help you as long as you come with me to the theater tonight.) Para que / A fin de que (So that / In order that)
