I am sorry to tell you, in modern era original Arabic (Fus-ha) is only used in school, books, news...etc., so you wouldn't use most of the words mentioned here in everyday life.Still, for me I can say that I have 


used maybe 6 of them,which counting from the bottom would be 2,3,6,7,8 and 9. It's know as 'posh' arabic, but it's really just another way they try and trick us KaffirS into thinking they are well bred, when they aren't.
