One way to classify the types of time travel in fiction is by the nature of the journey. There's the one - way time travel where the character can't return, and the round - trip time travel. We can also look at whether it's a conscious choice or involuntary. If a character is sent back in time against their will, that's different from when they plan and execute the time travel. And based on the destination, it could be to a specific historical period or a completely fictional time in the future or past.
We can classify them based on the method. For example, mechanical time travel using devices like time machines. Another way is by the direction, whether it's forward or backward in time. Also, we can classify according to the purpose. Is it for adventure, like in 'Doctor Who'? Or is it to fix something in the past?
We can classify them by their source. For example, some magic comes from within the magic - user, like an inborn power. Others come from external sources such as magical artifacts or places. Another way is by the effect they produce. Magic that heals is different from magic that destroys.
Classification of characters in crime fiction can be done in multiple ways. Firstly, according to their function, we have the solver (detective), the doer (criminal), and the sufferer (victim). Secondly, in terms of character traits, we can have the intelligent detective, the cunning criminal, and the vulnerable victim. Also, some characters can be grouped by their relationship to the main plot. For instance, there could be peripheral characters who are only loosely connected to the main crime but still play a part in the overall story.
We can classify them based on their roles. For example, the protagonists who drive the story forward, and the antagonists who create conflict.
Classification of characters in fiction stories can be done in multiple ways. Firstly, according to their function, such as the catalyst character who sets the events in motion. Then, by their emotional depth. Some characters are deeply emotional and complex, while others are more simplistic. And we can also classify them by their relationship to the central conflict. Are they directly involved in it, like the main combatants, or are they on the periphery, influencing the situation in a more indirect way?
One way is by their role in the story. Those who drive the plot forward are important. Another way is by their personality traits. For example, introverted or extroverted characters. Also, by their moral standing, like good or bad characters.
We could classify them based on the time period they are set in. There may be stories set in ancient times, medieval times, or modern times. Another way to classify them could be by the moral or lesson they teach. For example, stories about kindness, perseverance, or courage.
One type is the physical time travel. For example, in 'Back to the Future', Marty McFly travels through time in a time - traveling car. Another type is mental time travel, like in some stories where characters can relive past memories vividly as if they are actually there in that time. There is also the concept of time loops in fiction, such as in 'Groundhog Day', where the character keeps repeating the same day over and over again, which can be considered a form of time travel.
One way is by their role in the story. As I mentioned before, protagonists and antagonists are big categories. Another way is by their personality traits. Are they brave, cowardly, kind - hearted, or cruel? We can also classify them based on their development in the story. Dynamic characters change, while static ones don't. For instance, in 'The Great Gatsby', Gatsby is a complex character. His role as a protagonist is clear, his personality is a mix of romantic and naive, and he is a somewhat static character in that his dreams don't really change even as the world around him does.
Another way is by the target audience. Some romance novels are aimed at young adults and tend to have simpler storylines and more innocent love. These can be considered a lower level in terms of complexity. For adults, there are more complex levels with deeper themes and more mature relationships. There are also some romance novels that are specifically for older readers, which might deal with second chances at love or more complex family situations.
You can classify fiction books based on genre, like fantasy, mystery, romance, or science fiction.
