Rebecca, your thread title is cracking me up!
Somehow it came up in the other thread that a lot of signs are supposed to be signed along with special mouth movements called morphemes.
So, for example, if you are signing the word 'big' -- you are suppose to mouth 'cha' at the same time. If you don't -- then apparently you are proving you aren't fluent in ASL! Which I do a lot. hehe. Actually I lie, I don't know enough ASL yet to even be on the same continent of being fluent in ASL. Someday, I hope ...
Anyway ... here are some links to see how to mouth 'cha' at the same time you make the sign 'big' or 'large' --
Go to: http://www.aslpro.com/cgi-bin/aslpro/aslpro.cgi
Click on 'L' and then click on 'large.'
You can also click on 'B' and then click on 'big', but I like the way the first woman mouths it (mouths it, is that the right way to express that???) better.
I think Journey found the best web site though -- a dictionary just for Mouth Morphemes!
Really fascinating, but at the moment I'm worried how I'm ever going to be able to keep it all straight. A lot of the morphemes just don't seem intuitive to me.
