Something So Many Of Us Take For Granted,

writing,

so how did it start? this most probably an example of it's earliest known form, cuneiform, image above Jacob Dahl, developed more than 5,000 years ago in Mesopotamia, the land between the Tigris and Euphrates rivers where modern-day Iraq now lies, cuneiform captured life in a complex and fascinating civilization for some three millennia, new imaging techniques, combined with advanced machine vision tools, are helping to transform efforts to decipher ancient languages like Proto-Elamite, for a fuller detective story of our writing history have a look here, as an aside our own written and vocal language is changing all of the time, over time, languages evolve and change depending on the context in which they are being used, from Old English to Middle English, and from there to Modern and Contemporary English, many words have changed and taken new meanings and sounds, words do some truly inventive things when they change, and change they always do, some switch their sounds around, like when hros became hors, nowadays spelt with an extra e as horse, some lose their sense of having an internal composition, like when wāl-hros ‘whale-horse’ became walrus, Erich Round lists some more words that have switched their sounds through time, you can read about them on Morph.

and if you do this GIF will make sense!
