1. Preliminaries

25. To the question I say that the word ‘accident’ can be taken for what is per se signified by it or for what is denominated by what is per se signified (and this distinction is universal to all concrete terms). Further, when taking it for what is denominated by what is signified by the name, accident can be taken for what is absolute or for an accidental respect or relation.

26. Accordingly there are three divisions: namely about accident as concerns the per se idea that accident introduces; also about what is denominatively called accident and is absolute; the third division is about what is denominatively called accident and is relational.

27. Further, the predicate ‘to be in a subject’ or ‘not to be in a subject’ can be taken as to aptitude or as to actuality.
