The Spanish subjunctive, explained without tears

Most textbooks teach the subjunctive as a list of triggers: "after espero que, after cuando with future meaning, after no creo que…". You memorise the list, you forget the list, the subjunctive comes back.

Here is the shortcut I use with my students: the subjunctive is the mood of non-commitment.

When the speaker is committing to a fact, we use the indicative. When the speaker is not committing — because it is a wish, a doubt, a hypothesis, an emotion about a fact rather than the fact itself — we use the subjunctive.

*Sé que **viene**.* — I know he is coming. (Committed.) > *Espero que **venga**.* — I hope he comes. (Not committed; it is a wish.)

That is it. The "rules" are just the situations where Spanish speakers tend not to commit.

This single insight will not give you perfect subjunctive overnight, but it will turn the subjunctive from a list of arbitrary triggers into something you can feel.
