Subjuntivo: the mood for what doesn't exist yet
When you talk about what is wanted, demanded or still to come, the Spanish verb changes its ending completely. The result is the subjuntivo — the form for what does not exist yet. For example: “Es obligatorio que el contrato esté por escrito” — The contract is required to be in writing. A rule from the Spanish course: worked out on examples, not memorized as a wording.
How it works
When you talk about what is wanted, demanded or still to come, the Spanish verb changes its ending completely. The result is the subjuntivo — the form for what does not exist yet.
It is made by swapping the vowel: verbs in -ar get an e, verbs in -er and -ir get an a. Firmar → que firme, vender → que venda, recibir → que reciba. The stem comes from the yo form of the present: tener → tengo → que tenga.
Where it is obligatory. After para que: te lo doy por escrito para que no haya dudas. After words of duty and judgement: es obligatorio que firmes. After wishes: quiero que me lo confirmes.
A rule that saves time: two people acting means this form, one person means the plain verb. Quiero firmar against quiero que firmes.

How the rule settles in your head
A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
