We start interesting discussion in another thread and kind of take off topic so bringing here. Journey very helpful to explain 'cha' but wonder about 'pah' morpheme. Do you know where these originate from? Or when you use them with other sign? Are there *other* morpheme? Just want a place for us 'Oral' deafies to learn more about this. Maybe Journey and Jazz can re-post links from other thread so in one place?
