Koko has a sign language vocabulary of over 1000 words, which she uses in complex statements and questions.
Most of these signs are standard American Sign Language (ASL), but some are either invented or slightly modified by Koko
to form what we call Gorilla Sign Langue (GSL), or "Gorilla Speak." This section will help you become familiar with GSL,
and thus to learn to communicate both with Koko and those who know ASL.
We will gradually add more signs, more animation and phrases, and more in-context videos to help you learn more.
