Savory and spirit are two different types of uncategories. Savory starts by having a well defined and narrow category, flavor. Then it uses negation to eliminate a portion of that category. The color green isn't sweet, but that doesn't make it savory because green isn't a flavor. I have some other valid uncategorical definitions of this type.

A mongrel is a dog that doesn't belong to any recognized breed of dog. Manslaughter is the killing of one human by another human, without the intent of seriously wounding or killing. Health is the state of a living organism without significant disease or injury. Fiction is any story that does not represent actual events.

Spirit is a problem because it is an unanchored uncategory. It doesn't start with a known subset of thingspace, instead it starts with thingspace. To use older terms, a definition is generally genus and differentia. Spirit lacks a genus in the way that savory doesn't.
