hamartia

This term originates from Greek tragedy and carries a heavy, deterministic weight. It describes a specific type of error or character defect that is not necessarily a moral vice, but a blind spot or a miscalculation that triggers an inevitable catastrophe. It is most frequently used in literary criticism and academic analysis of drama rather than in casual conversation.

Because it refers to a singular, defining flaw in a narrative arc, the word is typically treated as a countable noun in academic discourse. However, it is rarely used in the plural unless discussing the various flaws of multiple different characters across several plays.
