* Their actions: What a character does reveals a lot about them.
* Their words: The way a character speaks, the words they choose, and their tone can be very telling.
* Their thoughts and feelings: If the story delves into a character's inner world, we can gain insight into their motivations and personality.
* Their appearance: While not always indicative of character, appearance can sometimes be a clue.
* How other characters react to them: What others say about a character, how they treat them, and their overall attitude can provide valuable information.
Essentially, indirect characterization is like solving a puzzle. The author provides clues, and it's the reader's job to put them together and form an understanding of the character.
