What can effective dialogue reveal about a character?

Effective dialogue can reveal a character's personality and their relationships with others because the way a character speaks, the words they choose, and their tone can provide deep insights into their traits and how they interact with those around them. For instance, a character who uses formal language may come across as more serious or reserved, while one who speaks casually might be perceived as friendly or laid-back. Additionally, through dialogue, you can observe how characters respond to one another, which reflects their feelings, dynamics in their relationships, and how they view others. These interactions can show not just who the character is but also how they fit into the larger social context of the story. This is why dialogue is a powerful tool in storytelling, helping to flesh out characters and enrich the narrative.
