hebrew - Why aren't Tefillin called Totafot?

They're called Totafot in the Torah, so why do we call them Tefilin?

Answer

Totafot is Hebrew Tefilin is Aramaic

Why there is no revival to call them Totafot, you'd have to be Gd to know why. Maybe because most of the people who like to bring back hebrew weren't themselves particularly religious. Or because Totafot only applies to the Tefilin shell Rosh... but still, nobody calls the tefilin shell rosh Totafot either.
