Which character serves as a mentor and guide for Janie in her journey?

Nanny serves as a mentor and guide for Janie, particularly in her formative years and the beginning of her journey. As Janie's grandmother, Nanny represents the older generation and provides Janie with knowledge about societal expectations, particularly regarding marriage and stability. She encourages Janie to seek a secure life, even if it means sacrificing her personal desires. This guidance shapes Janie's early understanding of love and relationships, influencing her choices as she navigates her journey throughout the narrative.

The other characters each play significant roles but do not fulfill the same mentoring function. Tea Cake, while an important figure in Janie's life, represents a more peer-like relationship and encourages her in her pursuits rather than guiding her through the complexities of life. Phoeby acts as a supportive friend, listening and providing companionship but does not provide the mentorship that Nanny does. Joe Starks, on the other hand, offers a contrasting perspective with his controlling and domineering nature, often stifling Janie's growth rather than guiding her positively. Thus, Nanny’s role as a mentor is pivotal in understanding Janie's development and journey in the story.
