Motif

Definition : any element, subject, idea or concept that is constantly present through the entire body of literature

Examples:  In all the famed fairytales, the motif of a ‘handsome prince’ falling in love with a ‘damsel in distress’ and the two being bothered by a wicked step-mother/ evil witch/ beast and finally conquering all and living ‘happily ever after’ is a common motif.

In the Book:  Ralph and Jack get into a fight and they split up the boys into two tribes. Jack's tribe has the most kids and takes control of Ralph's tribe. There is no one left in Ralph's tribe and Jack's has all the other kids.
