Describing Others AND MYSELF We have worked in the last two weeks on describing others. This lesson focuses in on the changes in pronouns and verb conjugations that take place in order to shift from describing someone else to describing oneself. The first descriptions on each slide are in the RDA Chapters 8 . and 9. 2. Module 2. Describing Persons. Scope of “Person”. Definition (RDA 8.1.2) .
