I'm afraid your source is quite thoroughly misinformed. For some of these words, the earliest example quoted in the OED happens to be from Shakespeare, but that certainly doesn't mean that he made them up; it just means that the earliest we can be sure that they were in use was somewhere around the time that he was writing. (It would be very strange for a playwright to make up so many entirely new words, especially for such familiar things as many of these words refer to.)
Some of the other words on the list, though, are demonstrably from before Shakespeare's time. The OED's earliest example of elbow, for instance, is from circa 1000. |
