What's the definition of tragedy according to Aristotle? and provide examples from Antigone the play by Sophocles

There are five rules created by Aristotle that classify a tragedy. All plays must have catharsis, a tragic hero, a change in fortune within a character, must be poetic, and happen in one location, in one day, and it is all closely related.

In the story, Creon locks up Antigone in a chamber for her wrongdoings. He realizes that what he did was wrong. He has a change of mind, from good to bad. This is an example of change within a character.

Antigone is an example of a tragic hero because of everything that had happened to her throughout her life. She lost her father Oedipus through a curse and her brothers through battle.

one type of the adjectives is predicate adjective. a predicate adjective is an adjective which follows a linking verb and modifies or refers back to the main subject of that linking verb.

it usually is used just before the noun it modies.

'penguins seem comfortable in the coolest habitats', comfortable is the predicate adjective which follows the linking verb 'seem' and modifies the noun.
