 Sophismata are found in a variety of texts, which scholars have categorized into different kinds. Abstractiones treatises are collections of sophismata arranged by a type of syncategorematic word (e.g., exceptive words, exclusive words, conditional words, disjunctive words, and so on), or sometimes by the distinction that is used to solve them. The material covered in each sophisma is mostly confined to a corpus. Syncategoremata are treatises devoted to syncategorematic words; in these treatises sophismata are used to illustrate or to give more refined explanations of the logical behaviour of the different syncategorematic words (or kinds of syncategorematic words). In Distinctiones treatises, the starting points are distinctions or logical rules connected with sentences that contain a syncategorematic word. The material in these treatises is usually organized around the type of syncategorematic word at issue. Besides these different kinds of treatises (the boundaries of which, however, are not very clear), we also find collections of sophismata that seem to be (fictional or faithful) reports of oral disputations. These collections can contain grammatical sophismata, but the latter are also found in separate, rather loosely-organized, treatises. Sophismata also play an important role in general manuals of logic, and in other works — often written by the same authors, or by different authors working in the same milieu as the former collections — with titles such as On Exponibles, On Consequences, Sophistry, etc.
