Why is learning American Sign Language a challenge?

In recent years there has been an explosion of interest in American Sign Language (ASL), the language used by Deaf Americans. As a result, an unprecedented number of schools and agencies now offer ASL classes. This welcome development signals growing awareness of and respect for the American Deaf community and ASL. Unfortunately, misconceptions persist about ASL. One major misconception is that it is an easily learned, picture-like language. This understanding is due partly to the fact that some of the first basic signs learned may be thought of as iconic (e.g., signs for eat, sleep, and drink). This even leads some new ASL learners to believe they can become instructors after one or two classes. This mistake is not made among people learning a spoken language. ASL is a complete and complex language, with all the nuances and subtleties of a spoken language. Like all languages, it is not mastered easily beyond a basic level. Mastery requires extensive exposure and practice. Presently, there is no consensus on where ASL might fall on a learnability continuum for native English speakers. Nonetheless, this article posits that learning ASL should be approached with respect and with the knowledge that mastery only occurs over a substantial period of time.
