As-tu repondu a la lettre se ta soeur?
How would I know whether to use indirect object pronoun or the pronoun y?
J'y ai repondu.
or
Je lui ai repondu.
Sorry i don't know how to do the accents.
If you have a PC (not a laptop) then accents are simple.
While holding down the Alt-key press the following numbers on the NUMERIC keyboard:
à = 133
â = 131
é = 130
è = 138
ê = 136
ë = 137
ô = 147
î = 140
ç = 135
Thank you for using the Jiskha Homework Help Forum. If you have a MAC, accent marks are even easier . If the chart Anonymous gave you doesn't work, let us know if you have Windows or not.
That is probably "de" ta soeur? Because you are replacing "à la lettre" your first choice is correct: J'y ai répondu.
If it were "As-tu répondu ta soeur?" Then it would be "Je lui ai répondu." It's when giving an answer to a letter, a question, etc. that it becomes "répondre à."

could it also be "Je l'ai repondu." Using direct object pronoun?
To determine whether to use an indirect object pronoun (lui, leur) or the pronoun y, you need to consider the preposition used in the sentence.
The indirect object pronoun is used when the preposition used is "à." In this case, "à ta soeur" indicates the indirect object, so you would use "lui" as the pronoun.
On the other hand, the pronoun "y" is used when the preposition used is "à" and refers to a location or an inanimate object. For example, if the question were, "As-tu répondu à la lettre?" (Did you respond to the letter?), you can reply, "J'y ai répondu" (I responded to it).
In your original sentence, since it mentions a person (your sister), you would use the indirect object pronoun "lui" and say, "Je lui ai répondu" (I responded to her).
No worries about the accents; I understand your message without them!
