 Cat·e·go·ry n.; pl. Categories
 1. Logic. One of the highest classes to which the objects of knowledge or thought can be reduced, and by which they can be arranged in a system; an ultimate or undecomposable conception; a predicament.
    The categories or predicaments -- the former a Greek word, the latter its literal translation in the Latin language -- were intended by Aristotle and his followers as an enumeration of all things capable of being named; an enumeration by the summa genera i.e., the most extensive classes into which things could be distributed.   --J. S. Mill.
 2. Class; also, state, condition, or predicament; as, we are both in the same category.
    There is in modern literature a whole class of writers standing within the same category.   --De Quincey.
