Often in stories, the protagonist has a support system (unless your novel takes place on a deserted island and the protagonist is the lone survivor of a terrible plane crash, in which case a volleyball named Wilson will just have to do). These characters can take the form of friends, family, coworkers, roommates, or any other number of relationships, but often they fulfill the role of the sidekick.
We discussed purple prose a few weeks ago, and as Newton’s Third Law of Motion states, for every action, there is an equal and opposite reaction. Or something like that; my college Practical Physics class involved making ice cream with liquid nitrogen. And the equal and opposite reaction to purple prose is beige prose.
If you want to learn how to be a super hero, you need an alter ego, but alter egos are everywhere, not just among those with super powers. The protagonist in your novel, whether super or not so much, can have an alter ego, too. In fact, alter egos are a great characterization strategy.
So we all know that typos are the worst! Terrible! They eat babies! They are AIDS! Etc, etc.
Now that that disclaimer is out there, there are some typos that I secretly love. And those are the ones that (unintentionally) completely change the meaning of the sentence because they end up being a totally different word. Those can be hilarious.
We’re all familiar with similes and metaphors, right? These can be great ways to infuse your writing with some punch and visual pizzazz. However, sometimes in the process of getting that metaphor written down, something happens, and the plane that was supposed to quickly and efficiently connect the object of your description and your metaphor ends up going all Oceanic Flight 815 on you and crashes somewhere on a remote island where weird things happen and you’re trying to get rescued, but have also kind of resigned yourself to the fact that you’re way off course and no one will be looking for you.
In other words, the last part of the previous paragraph is something you generally don’t want to do. I’m not aware of a specific literary term for a rambling or forgotten metaphor, but you generally want to avoid them.
