Answer:
The Giver: static, round
Asher: flat and static
Fiona: static
Jonas's parents: flat and static
Step-by-step explanation:
The Giver: The giver is actually a static and round character, because he has been the same since the beginning of the story. He didn't change, he has always been wise and carries the memories of the whole community.
Asher: Asher is a flat and static character because we don't know much about him except that he was friendly and enjoys having fun. And he does not develop feelings nor change throughout the story.
Fiona: Fiona is a static character because she does not change. She is the same character at the end of the book that she is at the beginning. She acts as a constant to compare Jonas to as he changes. Fiona changes a lot throughout the novel which makes her a static character.
Jonas's parents: Both Jonas's parents are static and flat characters, who don't change throughout the story and are not as well described. Al we know is that Jonas's father cares about the lives of the new children and that his mother is responsible for punishing people who disobey the rules of the community.
