The subjunctive is one of the three moods in Spanish, the other two being the indicative (actions, events, facts) and the imperative (commands). You can find more on the differences between the subjunctive and the indicative here!
The future subjunctive (el futuro del
subjuntivo
) is rarely used in modern Spanish. It was traditionally used in complex sentences with WEIRDO verbs that described a hypothetical, future action. Nowadays, the present subjunctive is used in virtually all cases in which the future subjunctive would have been used, but the future subjunctive does still appear, primarily in legal documents and literary contexts, so it’s good to be able to recognize it.
What's WEIRDO again?
Many of the verbs and phrases that require the subjunctive fit into the acronym WEIRDO: Wishes, Emotions, Impersonal expressions, Recommendations, Doubt/Denial, and Ojalá.

Any verb that is irregular in the third person plural of the preterite will maintain that irregularity in the future subjunctive. (Ex.
tener
)
