Readers of Regency romance novels are familiar with the ubiquitous figures of the jarvey and the Jehu on the box of one kind of vehicle or another. These two words are commonly used in modern writing interchangeably, as though they were synonymous. Yet, my reading of various Regency documents such as books, letters, diaries, newspapers and other periodicals over the years has led me to the conclusion that in actual fact these two words are quite antonymous. A jarvey is not a Jehu, nor is a Jehu a jarvey. Not to mention that a jarvey is not a coachman, but a Jehu might be.
So what is the difference between a Jehu and a jarvey?
