The 'Maybe' or 'Wish' Form
Desaparezca is the form you use when you aren't stating a fact. Instead, you're talking about a wish, a doubt, or a possibility (this is often called the 'subjunctive mood').
The Hidden 'Z'
Verbs like 'desaparecer' change their spelling to include a 'z' before the 'c' when they end in an 'a' sound. This helps keep the pronunciation consistent.
Using 'desaparece' after 'Espero que'
Mistake: “Espero que desaparece.”
Correction: Espero que desaparezca. Use the 'z-c-a' ending because 'hope' triggers the 'wish/doubt' form.
