I have heard that they add new words to the OED every year, but the ones I've heard of usually have to do with technology or something and usually they are few. I was reading a review on a book that taked about the compilation of the OED and they said when they were compiling words they went through books to find them. I am just wondering where the words came from originally. Can anyone just make up a word and give it a definition. I don't think it works like that, but then how do new words ever come about?
