The global language is pictures. A Doctor made an app that takes sentences and turns them into pictures that can be lined up with proper grammar. This teaches autistic people to communicate, it can teach a second language as well as a first (If you learned Japanese, it would be <japanese> means dog, but an American kid would learn <picture of dog> means dog. Essentially, you would learn french by <picture of dog> means chien), and it makes sense. [spoiler]side not: What language do deaf people think in? Pictures. What language do deaf, blind people think in? Feelings and Emotions What language do deaf, blind, paralyzed, sociopaths straight out of birth people think in? No one knows...[/spoiler]
