Concept
Logogram
Summary
In a written language, a logogram, logograph, or lexigraph (from Greek logo, "word", and gramma "that which is drawn or written") is a written character that represents a word or morpheme. Chinese characters (pronounced Hànzì in Mandarin Chinese, Kanji in Japanese, Hanja in Korean, Hán tự in Vietnamese and Sawgun in Standard Zhuang) are generally logograms, as are many hieroglyphic and cuneiform characters. The use of logograms in writing is called logography, and a writing system that is based on logograms is called a logography or logographic system. All known logographies have some phonetic component, generally based on the rebus principle.
Alphabets and syllabaries are distinct from logographies in that they use individual written characters to represent sounds directly. Such characters are called phonograms in linguistics. Unlike logograms, phonograms do not have any inherent meaning. Writing language in this way is called phonemic writing or orthographic writing.
Logographic systems include the earliest writing systems; the first historical civilizations of the Mesopotamia, Egypt, China and Mesoamerica used some form of logographic writing.
A purely logographic script would be impractical for many other languages, and none are known. All logographic scripts ever used for natural languages rely on the rebus principle to extend a relatively limited set of logograms: A subset of characters is used for their phonetic values, either consonantal or syllabic. The term logosyllabary is used to emphasize the partially phonetic nature of these scripts when the phonetic domain is the syllable. In Ancient Egyptian hieroglyphs, Ch'olti', and in Chinese, there has been the additional development of determinatives, which are combined with logograms to narrow down their possible meaning. In Chinese, they are fused with logographic elements used phonetically; such "radical and phonetic" characters make up the bulk of the script. Ancient Egyptian and Chinese relegated the active use of rebus to the spelling of foreign and dialectical words.
