Script of which the characters do not denote sounds, but whole words. A great many logographic characters each comprise componants that convey clues to the sound of the word as well as semantic componants that convey clues to its meaning. The phonemic constituents are derived from simple logographic characters, but used convey phonemic information through the rebus principle.
Such a script usually originated in a pictographic script (i.e. the characters form an image or the objects that are referred to) and often contains a lot of ideographic elements. The one big disadvantage of logographic scripts is that thousands of characters are needed to denote all words, which makes it extremely difficult to study.
A known example of a logographic script is the Chinese character script.
