Many people who decide to learn sign language believe that each English word has a sign for it. This is completely wrong! In American Sign Language, signs are based on what you're meaning to say, not the words itself. It's very important to remember that ASL is NOT English on the hands. It's not English in ANY way. It's a foreign language. As foreign as Japanese or German. To become fluent in ASL, it takes just as much work as any other language. About five to seven years of intensive training. This videos explains a little about how signs equal concepts and not words.
