yes that is an error. cadzu was changed in place structure, oh, maybe 5 yearsss ago, but after the textbook lessons were written, and Cowan missed that one occurance. Replace "cadzu" by the lujvo dzukla, which esssentially has the place structure of klama for purposes of examples. Thanksss for telling uss. Every one of thesse we find is one we can fix. lojbab
