how to make verbs to ing form
I don't know how to change simple verbs to ing form.
You need to use the present continuous tense:
What you do is you use the correct form of estar+ present participle.
To form the present participle you do as follows;
-ar verbs; remove -ar and add -ando.
-er and -ir verbs; remove the -er/-ir and add -iendo.
Eg. He is preparing dinner
Está preperando la cena.
