archetype
A perfect original model that many similar things are based on.
An archetype is an original model or perfect example of something that gets copied or referenced over and over again. Think of it like a cookie cutter: every cookie that follows has the same basic shape because they all came from that original pattern.
In stories, archetypes are character types that appear again and again across different books, movies, and myths. The wise mentor who guides the hero (like Gandalf or Obi-Wan Kenobi), the trickster who causes mischief (like Loki or Bugs Bunny), and the brave underdog who overcomes the odds are all archetypes. Writers don't copy these characters exactly, but they use the same basic pattern because these types feel familiar and meaningful to readers.
Archetypes exist beyond stories too. The log cabin is an archetypal American home. The small-town main street with shops and a courthouse is an archetypal community center.
When something is archetypal, it represents the purest or most typical example of its kind. Understanding archetypes helps you notice patterns everywhere: in the books you read, the places you visit, and even in how people act in different situations.
