Tropes are the things we find familiar, the events we see repeated in many books and films.
Specific sequence or moment the audience is used to seeing in a movie or reading in a book. Over time these moments have become an integral part of their genres. In many cases, the audience may be disappointed if they read a book that doesn’t contain the trope they expected.
Examples of Tropes: * Thriller: Cliffhanger * Spy: Martini Flavored or Stale Beer Flavored * Romance: Aborted Declaration of Love * Romance: Accidental Hand Hold * Action: Chase Scene * Action: Dress Rip * Comedy: Adults Are Useless * Comedy: All Balloons Have Helium * Comedy: Everything that can go wrong will go wrong. But it works out in the end.
Tropes are helpful tools. If you are new to a genre, it’s beneficial to know what is tried and tested and what the audience may expect and may be disappointed if they don’t get it.
