 It appears from Simplicius’ Commentary on Aristotle’s Categories (Kalbfleisch 1907 38.19–24) that Speusippus applied his method of division, however it worked, to language: there we hear of a division of terms even more elaborate than Aristotle’s in the opening chapter of the Categories: there we hear of homonyms, synonyms, and paronyms, but Speusippus differentiated between tautonyms (uses of the same term), within which there are homonyms (same term but different definitions) and synonyms (same term and same definition), and heteronyms (different terms), within which there are heteronyms proper (different names, different things), polyonyms (many names, the same thing), and paronyms (as in Aristotle: different terms and different things, with one term derivative from another, as ‘courageous’ and ‘courage’). Whether this classification was not only more elaborate than Aristotle’s, but also had a different basis (that in Aristotle being a classification of things according to how they are referred to, that in Speusippus being a classification of terms themselves), is in dispute (Barnes 1971, Tarán 1978).
