There is actually a book of supposed seldom used words and phrases and their backstories, which I got for Christmas. The title of the book is : LET'S BRING BACK THE LOST LANGUAGE.

Trump is a dynamo. He keeps getting better in presentation and substance.
That title sounds like something I would have purchased for my library (before I retired). I love interesting language!
