When writing a fiction piece, there are many ways to show characterization and bring the people in the stories to life.
Conflict is one of the ways characters are shown. A character can be in conflict with his environment, with himself or with another character. The character's actions and reactions to a conflict situation will reveal his true nature.
Action is another way to reveal a character's nature, how does he walk, what are his mental and emotional reactions to a situation calling for action? Knowing these things before describing the character in motion can add to the picture of who he or she is.
There are a number of types of tags that will characterize a story person. These include physical tags, such as the blond hunk or the skinny geek, appearance tags. Does the character wear what for them has become a uniform. He'd never seen her in a dress. Didn't he have anything to wear other than those ragged cutoffs. Mannerism tags. Does the character have a definite mannerism, such as running his hands through her hair or her twisting a strand of hair around her finger when she's nervous. Facial expression tags, Arching the eyebrow, a permanent scowl.
These are a few ways to show characters to the reader. Next week, I'll add more.
