7. Sign Language: Not all the Plains people spoke the same language. To communicate with other tribes, they developed a sign language, a language of hand movements. Over time, the same signs were used all over the Plains area. Usually, each band had at least one sign talker. The "talkers" understood over 3000 different signs. Some of the "talkers" could sign faster than you could speak. When Europeans first started entering the Plains region, various tribes communicated with these early explorers using sign language.
