Every effort will be made to research and include generally accepted signs. In some cases, signs may have been set up to be used in the classroom. These signs are suggestions and represent the closest approximation of the conceptually accurate sign. They are in no way meant to be finite signs, as there are many ways to sign many words and concepts. In all situations, however, it is highly recommended to finger spell the word right before or just after a sign is shown, just to cut down on confusion.
