The Road by Cormac McCarthy

I do not know what “crozzled” means. Nor do I know what “kerfs” mean, or “grambeled” or “sleavings” or innumerable other words introduced into the narrative. I have a vague idea of what the word “claggy” means in the sentence sequence, “The gray and rotting teeth. Claggy with human flesh,” but I don’t want to think too much about it. The end is nigh and woe is us (on The Road by Cormac McCarthy).
