A sandbox can be created by making a new page under the name of "User:XXX/Sandbox"

The XXX is your username, which would be KnaboKnehtaz, and "Sandbox" can be anything as long as it fits to what kind of sandbox you are making. Thus it can be "User:KnaboKnehtaz/EtymologySandbox" if you're using it for Etymology.
