 After providing his first system of classification, Aristotle turns to the predicamenta and presents a second, which ends up occupying him for much of the remainder of the Categories. Aristotle divides what he calls ta legomena (τἃ λεγόμενα), i.e. things that are said, into ten distinct kinds (1b25). Things that are said according to Aristotle, are words (De Int 16a3), and so it is natural to interpret his second system as a classification of words. And because the English word ‘category’ comes from the Greek word for predicate, one might naturally think of the second system as a classification of distinct types of linguistic predicates. There is, however, considerable debate about the subject matter of the second system of classification.
