Usually the adjective “asemic” (=signless) was linked by some dictionaries to “asemia” as a pathologic failure consisting in an inability to comprehend or express words, gestures or sounds. It was not related to the idea of ‘asemic writing’.
So, …after twenty years of asemic writing movement, this ‘Cambridge turn of events’ looks like a great achievement.
*
When the first (self-aware) asemic writing mags, sites, books and series started their journey, more than 20 years ago, the actual meaning of “a-semia” ( = a radical “absence of sign”, not an absence of semantic meaning) risked to put aside the very idea which grounded the practice of asemic writing.
On the contrary, now it seems that the use of the word “asemic” is better perceived as referred to an artistic practice, not a pathology. (according to Cambridge, at least).
