My OC is mute and uses sign language to communicate. I’m currently learning sign language so that I can get a sense of it and hopefully portray him more accurately. I know that usually sign names are given to others by deaf people, but would it be appropriate to give my OC a sign name that they would canonically use, or for them to give others in their universe sign names?

Also, is sign names for places a thing and would I be able to create sign names for different places that he would use?
