Dictionaries are critical tools for learning any language, and ASL is no exception. A good dictionary will allow you to look up signs you don't understand, as well as give you something to study. Look for a dictionary with easy-to-understand illustrations and descriptions. Try using an online dictionary, where you can see videos of the signs being produced. A classroom setting will give you multiple people to practice signing with, as well as feedback on your performance. Many colleges will allow you to take a class without enrolling. Check with your local school to see what programs they might offer. Community programs such as local libraries and recreational centers will often offer ASL classes for those that are interested. While a dictionary will show you how to sign every word or phrase, a study guide will get you signing in a more practical fashion. A study guide will provide more instruction than a dictionary, and will help you learn basic conversations as well as sentence structure. The internet can provide a wealth of information about signing, how to sign, Deaf culture, and more. There are many sites that contain video tutorials posted by professional ASL instructors. The ASLU is a great resource for new learners. Each entry has a video by professional instructors. Handspeak is another good video resource and online dictionary. YouTube is host to a variety of self-published videos on signing. Just remember that with anything online, anyone can make something regardless of whether or not they actually know what they are doing. Be wary of misinformation and improper techniques. With the advent of smartphones, carrying a dictionary and study guide around with you has never been easier. Both the Google Play Store and the Apple App Store have multiple options to choose from, ranging from free to a few dollars. Apps can be great for quick references, and some include video along with instructions. There are study guides and dictionaries, so try out a couple until you find ones that work for you. Look for apps that have a high number of 4 & 5 star reviews. Browse through some user reviews to see how helpful the app has been for other people.
