“Taxonomy is an ancient scientific practice. It means to find names for things. In naming things, you try to figure out how sets of things are related to one another, so that each, unique item will not only have a unique name, but also a reference to the others to which it relates. Taxonomy creates a hierarchy of inheritance, from general down to specific and back: A giant tree, on which there is a unique place for every item, like the leaves at the ends of twigs at the ends of branches connected to a trunk and running deep into the earth.” (The Content Strategy Noob) courtesy of basevers
