Subject: Prepositions with Infinitives

Instructions: Insert de or a on the lines.

1. Yo aprendo a leer en español.
2. El nieto corre a saludar a los abuelos.
3. Ya cesó de llover.

5. Mamá se encarga de cuidarnos.

Answer 1

Yes, they are correct. One way to determine when to use it is looking at the verb. Many verbs here end in "er" or "ar", meaning they are in the infinite format. In English, this is the equivalent of saying "To... (followed by a verb". So when you say, " I start to read in Spanish" or "Yo aprendo a leer en español", The "a" is like the "to". Also, "a" in spanish means "to" like in a direction or place. In the case for #2, you run TO/Towards los abuelos,

Answer 2

Looks like you have a good grasp of the grammar!! Keep in mind that "de" could also be used as an "from" and it used differently when it is an infinitive!! Great Work!!
