All the commentators who have suppressed the terminological difference between predicate and predication (κατηγορούμενον and κατηγορία) conclude that kategoria means 'predicate', thus lending their authority to a misreadng of the passages in which Aristotle uses the word κατηγορία to mean 'attributive proposition.' In this paper I take the position presented as an argument to support a different reading and with the hope that the established interpretation can be challenged through a fresh examination of the textual testimonies to accommodate the suppressed part of Aristotle's theory of categories as ultimate types of canonical propositions. The thesis that i seek to advance is, in technical language, that the categories stand for fundamental types of attribution that conform to rules formulated in accordance with the ontology of first substance, πρώτη οὐσἰα.
