Around 170 contemporary Polish surnames are analyzed that represent an expressive, though rarely encountered, derivational type. These surnames are modeled after paradigmatic substantive adjectives such as 'babi', 'lisi'. They can be derived from various bases, but primarily from given names and proto-surnames from given names or appellatives. In them the inflectional paradigm performs the function of a format. From the genetic point of view these surnames realize a nominational model of interrelation' whose is he', 'to whom does he belong'?
