Answer:
a character who permanently changes over the course of a story or novel.
Explanation:
In English literature, a character list comprises of both the protagonists and antagonists that are featured in a play. A protagonist is the lead, principal or chief (main) character in a story, play or film. Thus, a protagonist refers to the character that is being closely followed by an audience or a reader in order to determine the character's fate at the end of the story or play.
On the other hand, an antagonist is a character that opposes the protagonist.
Character development can be defined as a literary process or technique in which a writer portrays people as being real or believable in a work of fiction by ascribing depth (details) and personality to them.
Basically, various writers or authors use character development to make the audience or readers learn so much more about the characters as they develop in the story.
A dynamic character is a character who permanently changes over the course of a story or novel, especially a significant internal change in attitude or personality. Thus, it is considered to be the direct opposite of a static character that typically stay the same throughout the course of a novel or story.
