alphabet

“Alphabetic writing, like all technological systems and apparatuses, operates according to what might be called a corporeal axiomatic: it engages directly and inescapably with the bodies of its users. It makes demands and has corporeal effects. … The alphabet does this by imposing it own mediological needs on the body, from the evident perceptual and cognitive skills required to read and write to the invisible, neurological transformations which it induces in order to function. ”

The History of Writing

The pictograph for “water” pronounced nu became the symbol for the consonantal sound of N.; This practice of using a pictograph to stand for the first sound in the word it stood for is called acrophony and was the first step in the development of an ALPHABET or the “One Sign-One sound” system of writing.
