Read this passage from the article:
Sullivan began teaching Keller by using finger spelling. While Keller held an object in one hand, Sullivan would use her fingers to trace the letters of the object's name on Keller's other hand. At first, Keller struggled to understand. However, everything clicked one afternoon as the pair stood beside a water pump. Keller connected the feeling of flowing water with Sullivan's spelling of the word "water." It was like a dam had broken open.
