A **pasigraphy** (from [Greek](/source/Ancient_Greek) πᾶσι *pasi* "to all" and γράφω *grapho* "to write") is a [writing system](/source/Writing_system) where each written [symbol](/source/Symbol) represents a concept (rather than or not just a word or sound or series of sounds in a spoken language).

The aim is to be intelligible to persons of all languages. The term was first applied to a system proposed in 1796, though a number of pasigraphies had been devised prior to that; [Leopold Einstein](/source/Leopold_Einstein) reviews 60 attempts at creating an [international auxiliary language](/source/International_auxiliary_language), the majority of the 17th–18th century projects being pasigraphies of one kind or another,[1] and several pasigraphies and auxiliary languages, including some sample texts, are also reviewed in [Arika Okrent](/source/Arika_Okrent)'s book on constructed languages.[2] [Leibniz](/source/Gottfried_Leibniz) wrote about the [alphabet of human thought](/source/Alphabet_of_human_thought) and [Alexander von Humboldt](/source/Alexander_von_Humboldt) corresponded with [Peter Stephen Du Ponceau](/source/Peter_Stephen_Du_Ponceau) who proposed a universal [phonetic alphabet](/source/Phonemic_orthography).

Examples of pasigraphies include [Blissymbols](/source/Blissymbols), [Real Character](/source/An_Essay_towards_a_Real_Character,_and_a_Philosophical_Language), [IConji](/source/IConji) and [Yerkish](/source/Yerkish).
