When I started learning ASL in 2009 I had a Deaf co-worker who just started showing me signs while we were at work. She started tutoring me and I also started going to as many social events I could with signers. I definitely learned different things from tutoring and social settings. I think someone trying to learn could always start with one or the other, but in the long run I think I benefitted from having both one on one tutoring and socializing in only ASL on a regular basis.

I would say that you can probably begin just teaching yourself signs and some grammar online, but I definitely believe that you will eventually need a tutor or teacher. I believe this because, like any language, ASL has certain characteristics and things that can only be learned from a native/extremely good teacher. I recommend finding a teacher who is d/Deaf, hard of hearing, or very familiar with ASL and the Deaf community (most likely an interpreter). Additionally, if that person is someone from around where you live that is better because of there are some regional signs that vary from state to state.

I am an ASL teacher!
