The writing is restricted by a pseudo-
alliterative rule of the
lipogram type: the first chapter contains only words starting with the letter
a, the second chapter only words starting with
a or
b, etc.; each subsequent chapter adds the next letter in the alphabet to the set of allowed word beginnings. This continues for the first 25 chapters, until at last Abish is (briefly) allowed to write without constraint. In the second half of the book, through chapter 52, letters are removed in the reverse order that they were added. Thus,
z words disappear in chapter 27,
y in chapter 28, etc... == Errors ==
