Answer:
I will give you a few examples to help you better understand:
Explanation:
Here are three verbs I chose to start with:
The three verbs above are already in their infinitive form with the endings (-er, -ar, -ir).
Comer (to eat)
Hablar (to speak)
Venir (to come)
Now, let's put them all in the participle form with the attached endings (-ado, -ido):
Comido
Hablado (spoken)
Venido
*the -ar endings are replaced with -ado while the -er/-ir verbs are replaced with -ido
Let's turn them into gerunds (-ing) with the endings (-ando, -iendo):
Comiendo (eating)
Hablando (speaking)
Vendiendo (coming)
*the -ar ending is replaced with -ando while the -er/-ir endings are replaced with -iendo
