Abstract Character:
* When referring to the qualities, traits, or personality of a person or thing.
* Example: "The novel's main character has a strong, independent character."
* When referring to a symbol, letter, or mark used in writing or printing.
* Example: "The text uses different characters to represent different sounds."
Concrete Character:
* When referring to a fictional person in a story or play.
* Example: "The main character in the movie is a detective."
* When referring to a real person, especially when emphasizing their personality or reputation.
* Example: "She is a character of great integrity."
Therefore, the classification of "character" as abstract or concrete depends on the specific context in which it is used.
