In linguistics, a grapheme is the smallest functional unit of a writing system. The word grapheme is derived from Ancient Greek's gráphō ('write'), and the suffix -eme (by analogy with phoneme and other emic units). The study of graphemes is called graphemics. The concept of a grapheme is abstract; it is similar to the notion of a character in computing. (A specific geometric shape that represents any particular grapheme in a given typeface is called a glyph.) In orthographic and linguistic notation, a particular glyph (character) is represented as a grapheme (is used in its graphemic sense) by enclosing it within angle brackets: e.g. ⟨a⟩.

Written character in the context of Logographic
In a written language, a logogram (from Ancient Greek logos 'word', and gramma 'that which is drawn or written'), also logograph or lexigraph, is a written character that represents a semantic component of a language, such as a word or morpheme. Chinese characters as used in Chinese as well as other languages are logograms, as are Egyptian hieroglyphs and characters in cuneiform script. A writing system that primarily uses logograms is called a logography. Non-logographic writing systems, such as alphabets and syllabaries, are phonemic: their individual symbols represent sounds directly and lack any inherent meaning. However, all known logographies have some phonetic component, generally based on the rebus principle, and the addition of a phonetic component to pure ideographs is considered to be a key innovation in enabling the writing system to adequately encode human language.
