Spanish expressions that require the subjunctive


In Spanish, the subjunctive is required after certain expressions. For example, these include some conjunctions, impersonal expressions, and expressions of wishing, willing, commanding, or doubting. However, we have to be aware that some of these expressions are used with que and some without it.
