The excerpt from "The Miracle Worker" suggests that learning the word "water" was a significant and transformative moment for Helen Keller. It builds on the idea that this learning experience was akin to triggering a deep, buried memory. The struggle Helen exhibits as she tries to articulate the sound of the word—her trembling lips and the emergence of a "baby sound"—indicates that this was not an easy or straightforward process for her.
Rather than implying that Helen knew the word "water" prior to her experiences or that language came easily to her, the text highlights the profound challenge she faced in connecting the concept of "water" with her understanding and expression. The moment is portrayed as a breakthrough, characterized by an intense struggle and emotional depth as light seems to come into her face, symbolizing a realization and newfound comprehension.
Therefore, it does not simply illustrate how happy Helen felt, but instead emphasizes the complexity and depth of her emotional journey in learning and communicating this fundamental concept. The moment is not just about the joy of understanding; it's about the labor and triumph of breaking through barriers to reach that understanding.
