This article is an attempt to reinterpret a rather obscure category of monuments - the so-called pseudogroups. One royal and a few dozens of private pseudogroups dated for V and VI dynasty are known. They were interpreted very differently by various scholars who dealt with them. The discussion of so far proposed theories is followed by a new interpretation. Its essential ideas are: 1) the statue of the deceased is a body in which his k3 lives and takes offerings; 2) a noticeable feature of the kA is its heredity; 3) one of the principles of egyptian logic is complexity of unity and multiplicity. The result of these assumptions is the interpretation of pseudogroups as a kind of specific family groups.
