For example, when
Little Red Ridinghood is told by the wolf that his teeth are so big the better
to eat her with, the wolf is giving a final cause of why his teeth are so big,
but this is not {mu'i}. Perhaps {te pi'o}.
The material cause of something is what it is made of, and the formal
cause of something is what its form is. These might be {se ma'e} and
{te ma'e}, but we probably wouldn't call them causes.
Those aren't causes. -epkat
