Ginny grinned, thinking now of what she could design her note book with. She put up her hand "a person who studies arithmacy is an Arithmancer. arithmacy is made from two greek words "ginny hesitated trieng to remmeber then it clicks " from the two words arithmos and manteia. arithmos meaning number and manteia meaning divination." she raked her brain for more."the purpose of arithmacy is studying occult numbers that for example your birth date and name and tell you about your potentials and challenges." she finished and smiled hoping she had gotten it correct.
