Final answer:
Annie Sullivan adapted the alphabet for Helen Keller by creating finger-spelling signs on her palm, enabling Helen to understand the connection between words and physical objects, significantly advancing her language skills.
Step-by-step explanation:
Annie adapts the alphabet to suit Helen's needs by creating finger-spelling signs on Helen's palm. Through this innovative method, Helen Keller was able to connect hand-spelled words to physical items, despite her inability to see or hear. The technique involved spelling out the letters of words on Helen's hand, which initially seemed like a game to her. Over time, through persistent teaching from Annie Sullivan, Helen came to realize that every object had a name and that these names could be communicated through finger spelling. This critical literacy moment transformed Helen's understanding of the world around her and laid the foundation for her future achievements in language and communication.
