The word asemic means "having no specific semantic content,". Asemic writing doesn't carry specific linguistic or verbal content, therefore inviting the viewer to create their own meaning, similar to how one might interpret and find meaning in other forms of abstract art. Unlike other forms of Abstract art, asemic writers/artists retain the use of the physical characteristics associated with writing, such as lines and symbols that seem to mimic the text of a 'real' language or alphabet.
As many of you know, this form of writing plays a central role in much of my artwork, although I also work with 'real' letters and words from time to time as well. ;)
