2.5

述曰：二、列名也。同者相似，法謂差別。共許自性名為有法，此上差別所立名法。今與彼所立差別相似名同法，無彼差別名為異法。異者，別也。

The commentary states: The second part lists the names. 'Similar' means resembling; 'dharma' means the distinction (viśeṣa). The mutually agreed-upon subject (svabhāva) is called the possessor of the property (dharmin), and the distinction posited upon it is called the property (dharma). Now, being similar to that posited distinction is called the example of similarity; lacking that distinction is called the example of dissimilarity. 'Dissimilar' means different.
