Did you know that Dickens' A Christmas Carol, though a novella, is not broken into "Chapters," but "Staves."
According to Webster's Dictionary, a 'stave' is a vertical wooden post or plank. I presume that Dickens chose to use 'stave' instead of 'chapter' as both a symbolic post to divide the story, but as to vertically stretch across the page like a bookmark, though this is only an elaborate assumption and I have found no proof in the pudding.
That being said, The Ghost of Christmas Past is also divided into staves rather than chapters; six staves to be precise.
Should anyone know why Dickens had chosen to use staves, please leave a comment or reply by email to: firstname.lastname@example.org I am eager to be enlightened.
