Hermione often uses her quick wit, deft recall, and encyclopaedic knowledge to help her friends in perilous situations. Rowling has stated that Hermione resembles herself as a young girl, sharing similar insecurity and fear of failure. [2] Hermione has been immensely popular. Here are some things you might not know about Miss Granger, plus a few details you may have missed on your first read… Her name has roots in Greek mythology… ‘ Hermione ’ is the female derivative of ‘Hermes’, a messenger god known for his sharp wit and ability to transition between worlds. Quite fittingly, Hermione transitioned between the Muggle and wizarding worlds, delivered information (seriously, has nobody else read Hogwarts: A History?) and was pretty sharp-witted herself. Hermione can be extremely ruthless when it comes to protecting what she believes in - the most notable example is the parchment containing the Dumbledore's Army members' names. Hermione tells no one - including Harry and Ron - she's secretly cursed the parchment.
