Existence is presented in the Book of Causes with the term "Anniyya" (esse) meaning "Being" and "huwiyya" (ens), meaning "being" and "Kawn" meaning "coming to be" and the meaning of existence is different for the hierarchy of existence. The meaning of existence for the first cause is Pure Existence. Still, for other levels of intellect and soul, it is "limited existence." Based on the eighth chapter of the Book of Causes, Thomas said in the description of this book that "existence" in the Book of Causes does not mean "act of being". Therefore, we raise the issue of what meaning of "existence" is used in the Book of Causes. Is it possible to give another answer to Thomas's theory? To investigate this issue and answer these questions with a descriptive-analytical method, we explain the different terms of existence and their semantic usage in the Book of Causes. We come to the conclusion that "existence" refers to God, Pure Being, for the "first intelligence being" and for creatures, it means "give existence".
