The process of labeling product categories using excessive and unnecessary descriptors.
Over qualifying product categories with more information than is required does not add anything of value to the product hierarchy. It only creates longer label names that make the hierarchy more difficult to navigate. The goal of category labeling is to convey the concept that links the products together as succinctly as possible. Often the excess descriptors can be managed in an attribute within the category. An example would be an category labeled "Fixed & Adjustable Wrenches" when it could just be labeled "Wrenches".
