"Infinitives" at the beginning of a sentence = gerunds ?

Question

In my Spanish book, it gives a girl's weekly schedule.

For every day of the week, the sentence will start with an infinitive. For example:

lunes - Estudiar a la casa de mi amiga. martes - Ir a mi tienda favorita. miércoles - Llamar a mi abuela

For lunes, is it literally saying, "Studying at my friend's house." ? For martes "Going to my favorite store." ? For miércoles, "Calling my grandma." ?

It's confusing me because usually I think of infinitives as "to study, to go, to call" but that wouldn't make sense her. I know that infinitives can function as gerunds as well.

Answer 1

Spanish verb infinitives may serve as English gerunds (not the gerundio). Therefore, they are nouns (or form a noun clause).

Note: they are normally translated using the ing form of the verb. Therefore, not to go, to call, but going..., calling... (but to go, to call are not incorrect )
