Children's literature is an umbrella term that includes many genres, discourses, and texts. It is difficult to define the term according to the literary work itself; instead, it can be defined according to the function, target reader, and elements of the work. In other words, a work can be recognized as a children's literary work if it achieves the functions of children's literature. That is to say, children's literature can be defined as a work, with complete literary elements, that is intended to entertain, educate, and motivate children. Like any intellectual human production, either literary or artistic, children's drama and novel require a well-established mechanism of explaining, interpreting, and construing it in order to be well-perceived. The process of reading and understanding any artistic-literary work not only necessitates perceiving the literal meaning of the text, but also it requires understanding its deeper meaning as well. Thus, the present paper aims at defining and analyzing the main elements of children's novel and drama in terms of hermeneutics theory. Born in the womb of theology, mutated as a philosophy to discuss and analyze all kinds of texts either religious or secular, hermeneutics has emanated as one of the most effective intellectual practices which is able to interpret any human activity due to its comprehensivity and logical approach. The main purpose of applying hermeneutics theory to children' novel and drama is to avoid telling and teaching “poisonous literature" to children.
