LENGUA RICA STUDENT QUESTION
Escribo "gracias por ayudando mi hijo." Pero Google dice "gracias por ayudar a mi hijo". Porque ayudar y no ayudando?
LENGUA RICA ANSWER
Two reasons.
1. "por" is a preposition. In Spanish, whenever a verb comes after a preposition, that verb always takes the infinitive form.
2. When we say "Thank you" or "Gracias," we are always thanking for some THING, whether it's an actual object or an action of some kind. Linguistically, we give thanks for a noun. If I say, "Thanks for coming," the word "coming" is acting like a noun. A verb that serves that function is called a "gerund." A gerund is "a form that is derived from a verb but that functions as a noun, in English ending in "-ing." (New Oxford American Dictionary) But in Spanish, the verb form that serves that purpose is the infinitive. That's why "Gracias por ayudar" is correct, rather than "Gracias por ayudando."
