In Lois Lowry's The Giver, the community doesn't call their homes "houses," they call them "dwellings." People don't live with their blood relatives because people are scientifically placed together for maximum effectiveness of rearing children. For example, parents are not in love with each other. They are placed together as if they were business partners given the duty to raise children who will obey the rules of the community. Hence, the word "dwelling" seems to create a more business-like sound to it than the emotionally charged word "home." Furthermore, the dwellings are all the same around the community in order to represent Sameness, the philosophy upon which the society exists.
An annex is an additional section of building added to an already existing one. The Giver lives in an annex, or addition, to the House of the Old. In chapter 10, Fiona and Jonas are reporting to their assignments and Fiona goes in the front door of the House of the Old. Jonas heads around back to the annex, or the newer addition to the building which happens to be living quarters for the Receiver of Memory. The evidence is as follows:
"Jonas nodded, waved to her, and headed around the building toward the Annex, a small wing attached to the back. He certainly didn't want to be late for his first day of training. . ." (72).
