1.Why is it a and not de?

Question

1.El me ayudó mucho _______________ hacer la tarea

Answer 1

Spanish verbs used with preposition

ayudar a to help

Look under verbs that use "a" followed by an infinitive to find ayudar a + hacer in this example.

Answer 2

In this case it seems to me it's using the meaning of 'a' that's sorta like 'by'. Which would make the sentence mean something like 'He helped me a lot by doing the homework.' Also, I believe ayudar is always followed by an 'a' for that. If I'm wrong anyone, please correct me.

I believe ayudar is always followed by an 'a' for that - that's what you want to hang on to here, it's just the way the language is used. - Jeremias, Jan 2, 2012

Answer 3

he helped me "to" (a) do it, not "of" de , do it.
