Explanation:
Indirect characterization through speech
A character is revealed by what he or she says and by what other characters say about the character. For example, in “The Most Dangerous Game” by Richard Connell, a famous hunter, Rainsford, is lost at sea and washes ashore on an island owned by General Zaroff.
Sanger Rainsford
A world-renowned big-game hunter and the story's protagonist. Intelligent, experienced, and level-headed, Rainsford uses his wits and physical prowess to outwit General Zaroff. ... Hiding from Zaroff, he recalls his days fighting in the trenches of World War I, where he witnessed unimaginable violence.
An example of direct characterization is when Rainsford meets General Zaroff and the narrator explains: "Rainsford's first impression was that the man was singularly handsome; his second was that there was an original, almost bizarre quality about the general's face.
