Can someone explain to me about Harmatia, Hubris, Plot, Reversal, and Stage Manager in simple terms please and thank you! It's for Theatre!!!

Hamartia is a literary term that refers to a tragic flaw or error that leads to a character's downfall. In the novel Frankenstein, Victor Frankenstein's arrogant conviction that he can usurp the roles of God and nature in creating life directly leads to ruinous consequences for him, making it an example of hamartia.

Hubris is the characteristic of excessive confidence or arrogance, which leads a person to believe that he or she may do no wrong. The overwhelming pride caused by hubris is often considered a flaw in character. ... Hubris often causes humiliation to whom it is directed.

Finally, here's a list of all the plot types referred to in Mark Nichol's article:

Overcoming the Monster.

Rags to Riches.

Voyage and Return.

Comedy.

an act or the process of reversing. 2 : a conversion of a photographic positive into a negative or vice versa. 3 : a change (as of fortune) often for the worse.
