I was reading the book The Information: A History, A Theory, A Flood by James Gleick.
Towards the beginning (third paragraph) of chapter three, titled Two Wordbooks, the author writes -
The alphabet, however, had a definite order—the first and second letters providing its very name and that order had been maintained since the early Phoenician times, through all the borrowing and evolution that followed.
The context just before introducing this sentence does not make the meaning clear right away. I am guessing what the author wants to say is that the very word "alphabet" is a derivative of the first two letters of the alphabet system - "alpha" and "beta" respectively.
Am I correct in guessing the intent and the actuality of this claim? Or does the author indicate towards something else?
