Grapheme

Various glyphs representing instances of the lower case letter a, considered to be allographs of the same grapheme

In linguistics, a grapheme is the smallest functional unit of a writing system.[1] The word grapheme is derived from Ancient Greek gráphō ('write'), and the suffix -eme by analogy with phoneme and other emic units. The study of graphemes is called graphemics. The concept of graphemes is abstract and similar to the notion in computing of a character. By comparison, a specific shape that represents any particular grapheme in a given typeface is called a glyph.
