Questions & Answers about ¡Fuiste tú el que intentó acceder al servidor!
Why does the sentence use intentó (third person) instead of intentaste (second person) if it is talking to tú?
Why is the first verb fuiste instead of fue, since in English we say "It was you"?
Can I use quien instead of el que in this sentence?
Yes, you can say Fuiste tú quien intentó acceder. Using quien is perfectly correct but sounds slightly more formal. In everyday spoken Latin American Spanish, using el que or la que is very natural for this kind of emphasis.
Why do we need al before servidor?
