1. Holden's Desire to Protect Innocence: The term "catcher in the rye" refers to a person who stands at the edge of a rye field and catches children before they fall off a cliff. In this context, Holden longs to be the protector of innocent children, shielding them from the harsh realities and corruption of the adult world. He desires to preserve their innocence and prevent them from experiencing the pain and disillusionment that he has faced.
2. Symbol of Transition and Loss of Innocence: Rye can be seen as a metaphor for the transition from childhood to adulthood. As Holden walks through the rye field, he is on the cusp of adulthood and is filled with anxiety about the impending loss of his childhood innocence. He fears growing up and entering a world that he perceives as superficial and corrupt.
3. Seeking Refuge and Connection: The rye field can be interpreted as a place of refuge for Holden. It offers him a sense of solace and escape from the phoniness and materialism of society. Holden finds comfort in the simplicity and naturalness of the rye field, which contrasts sharply with the artificial and superficial world he encounters in his daily life.
4. Symbol of Rebellion: Rye might also symbolize rebellion against societal norms and expectations. Holden's alienation from society and his desire to defy conventions are reflected in his association with the rye field, which represents an alternative to the traditional path that society prescribes for individuals.
5. Allusion to Innocence: "Comin' thro' the rye" is a line from a Scottish folk song that Holden hums throughout the novel. The line's reference to youth, love, and innocence adds another layer of symbolism to the title, reinforcing Holden's longing to preserve his innocence and his apprehension about entering the adult world.
