Abstract
In his commentary on Aristotle’s De intepretatione, Ammonius criticises the view, which he ascribes to Alexander of Aphrodisias, that epirrhêmata, ‘adverbs’, fall under the rubric of onoma. While it is difficult to establish Alexander’s view on the basis of Ammonius’s criticism, I argue that an intelligible view can be reconstructed, mainly based on evidence in Alexander’s commentary on the Topics, about different types of adverbs. In particular, I suggest that Alexander, apparently unlike Ammonius, may have drawn a distinction between two classes of adverbs Aristotle deals with in his logical writings: tropoi (modal operators); and ptôseis, i.e. the specific type of ‘inflections’ (adverbs in -ôs derived from a noun – usually an abstract noun) playing a prominent role in several of the topoi Aristotle gives in the Topics.
