"T`as" is just a gramatical junction, a little bit just like your "`cause" wich come from the word because. In french , this is used a lot, in grammary it`s call "Illiaison".Alors t`as compris où tu as compris, c`est exatement la même chose!Le temps verbaux peut se conjuguer de diferentes formes, par example: J`ai compri, T`as compris, il a compris, nous avons compris ou alors on a compri, vous avez compris,ils ont compris!French is a complex language, like the portuguese, spanish and all the other languages that became from latin, but it`s not so very dificult to learn them, if we really want to.
