Jhumpa Lahiri's quote highlights the vastness of knowledge and the limits of our understanding. The unknown words symbolize the complexities of the world and serve as a reminder of how much there is still to learn. This realization can be humbling, as it fosters a sense of curiosity and a desire to explore new ideas and concepts.

In her book "In Other Words," Lahiri reflects on her journey of language acquisition and the challenges of expressing herself in a new tongue. This struggle is not just about communication; it's also about connecting with different cultures and perspectives, reinforcing the notion that embracing the unknown enhances personal growth and broadens one's worldview.
