Welcome back!

History has many important lessons to teach, and so the WordMaster felt it was time to teach a few important lessons about history itself. Our job this week is to give you an introduction to the language of history, especially the economic history that is of such concern to anyone with an interest in business.

Look forward to it, because this week is going to be one for the history books!
