In the meantime, you could go back to this earlier post, which is a virtual duplicate. There you find detailed explanations, to which you will need to refer back again and again, until the knowledge becomes solid. It's the nature of the beast....When do you write -la and when -a?
I am not sure if it is a rule, and I am sure my english doesn't help, but in this case I think that there is a reason for the use of 'la' as pronoun, instead of 'a'.Hi!
I don’t understand why the difference in the following sentence:
“Você só conseguirá testá-la mostrando-a e conversando com o maior número de pessoas possível.”
I find this very confusing. When do you write -la and when -a?
