Characterization is a way in which a writer builds his or her character/s. When the writer uses conversations between characters as a way of constructing the character/s, it is referred to as dialogue.
Dialogue is a method of characterization that focuses on how characters interact with one another. Dialogue helps to bring out the character's personality by showing how they interact with others.
Example: If the character makes a lot of jokes and is very pleasant towards others they interact with then that shows the reader that the character has a funny and friendly personality.
Dialogue shows how the other character/s respond to the character. This aids the reader to understand what the others think of the character.
Example: If the other characters laugh at the jokes told and are also pleasant to the character, this then shows the reader that the character is indeed a friendly and funny person.
Dialogue is also used to depict a character's tone. This also helps the writer to show the character"s personality.
Example: If the character says mother i want that toy right now. The reader will then assume the character is a bossy and spoiled person. If the character says mother can you please buy that toy for me then the reader will assume that the character is well-mannered and pleasant.
Dialogue also helps the reader to understand and possibly relate to the character's emotions and motives.
Example: If the reader is in a scary situation and is having a conversation with a friend pleading for their friend's help. This helps to further emphasize the point that the character is indeed afraid.
