"Where did you go afterwards?"

[dennisk2v]

When do you use donde vs anonde?

[Robbadob]

Adónde means "to where" (whither), while dónde just means "where". English speakers often omit the "to" in "to where", so you get "where" being used in both places.

There doesn't seem to be a hard and fast rule although the use of the accent is important:

Adonde saliste después - not accepted. Can anyone explain why? Thanks!

[Conversely]

"Ir"= to go. "Salir"= to go out.
