If you have ever seen the movie or the stage play The Miracle Worker, you are familiar with the scene of Anne Sullivan holding Helen's hand under the water pump, and spelling out the word 'w-a-t-e-r' as it flowed over her hands. Until this point Helen had learned to spell 'd-o-l-l' but it had no literal meaning for her in her own mind.
