Taxonomy (general), the practice and science of classification of things or concepts, including the principles that underlie such classification. Folk taxonomy, the way people describe and organize their natural surroundings. Folksonomy, classification based on user's tags.
In WordPress, a taxonomy is a grouping mechanism for some posts (or links or custom post types). The names for the different groupings in a taxonomy are called terms. Using groupings of animals as an example, we might call one group birds, and another group fish. Fish and birds are terms in our taxonomy. As an example from WordPress, a category or tag (see next section) is a term.
