The subjunctive mood in Spanish is really important when you want to share wishes. Here are the main forms you should know:

1. Present Subjunctive:

   • You use this for wishes about now or the future.
   • To make it: Start with the "yo" form in the present tense. Take off the -o and add:
     • For -ar verbs: e, es, e, emos, en.
       (Example: "que yo hable" means "that I speak.")
     • For -er/-ir verbs: a, as, a, amos, an.
       (Example: "que tú comas" means "that you eat.")

2. Imperfect Subjunctive:

   • This form is for wishes about the past or things that aren’t real.
   • To make it: Take the "they" form from the past tense, drop -ron, and add:
     • ra, ras, ra, ramos, ran.
       (Example: "Si yo fuera rico" means "If I were rich.")

3. Present Perfect Subjunctive:

   • This form is for wishes about things that might have happened.
   • To make it: Use "haya" + past participle.
     (Example: "Espero que él haya llegado" means "I hope that he has arrived.")

4. Past Perfect Subjunctive:

   • This form shows wishes about things that didn’t happen in the past.
   • To make it: Use "hubiera" + past participle.
     (Example: "Ojalá que ella hubiera venido" means "I wish she had come.")

When you use these forms correctly, you can express your wishes and talk about imaginary situations in Spanish more easily!
