Grapheme

A Grapheme is a linguistic symbol within a writing system that functions as the fundamental written unit of language representation through visual encoding of linguistic information.

• AKA: Writing System Character, Written Linguistic Symbol, Orthographic Unit, Script Element, Written Language Unit.
• Context:
  • It can typically be a member of a Language Grapheme Set with grapheme inventory characteristics specific to that language system.
  • It can typically be used by a Linguistic Agent to compose Written Utterances through grapheme combination patterns.
  • It can typically convey Linguistic Information through grapheme interpretation processes in grapheme reading activity.
  • It can typically form Grapheme Sequences that encode grapheme-based language structure and grapheme-encoded meaning.
  • It can typically be distinguished from other graphemes by its grapheme visual form and grapheme functional role.

  • Font Glyph, which provides a specific visual rendering of a grapheme rather than being the abstract grapheme itself.
  • Character Encoding, which is a computational representation scheme for graphemes rather than the grapheme unit itself.

  • In linguistics, a grapheme is the smallest unit of a writing system of any given language. An individual grapheme may or may not carry meaning by itself, and may or may not correspond to a single phoneme of the spoken language. In other words, a grapheme is a letter or a set of letters that represent a sound (more correctly, phoneme) in a word. Graphemes include alphabetic letters, typographic ligatures, Chinese characters, numerical digits, punctuation marks, and other individual symbols. A grapheme can also be construed as a graphical sign that independently represents a portion of linguistic material.

    The word grapheme, coined in analogy with phoneme, is derived , and the suffix -eme by analogy with phoneme and other names of 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 specific typeface is called a glyph. For example, the grapheme corresponding to the abstract concept of "the Arabic numeral one" has a distinct glyph with identical meaning (an allograph) in each of many typefaces (such as, for example, a serif form as in Times New Roman and a sans-serif form as in Helvetica).
