Semasiography

Semasiography (from Greek:σημασία (semasia) "signification, meaning" and latin /ˈlætᵻn/ (graphia) "writing") is "writing with signs", a non-phonetic based technique to "communicate information without the necessary intercession of forms of speech." It predated the advent of the creation of the language-based writing system and is used contemporarily in computer icons, musical notation, and mathematical notation. It is studied in semasiology within the field of linguistics.
