SUN (Symbolic Universal Notation) is a symbolic representation of all the words in Scripture. It consists of a small group of universally recognized characters that are then combined or altered to make additional symbols which are called extensions. Between the characters and extensions, all of Scripture can be represented. The symbols in SUN are taught using illustrations to improve retention. The example on the left shows the symbol for "Person" and "Write" makes up the symbol for "Author, writer, or scribe."
