WRITING AND TRANSCRIBING: A GRAPHIC SYSTEM FOR SIGN LANGUAGES. No genuine writing system has ever been developed for sign languages because of the issue of representing their spatial and multidimensional nature. Unlike for spoken languages, no rupture in modalities between oral and writing (gesturing visual) appears for sign languages (SLs). The sh...
