Yes. Another way to say the ending of a novel could be 'the last part'. This is a very simple way to put it. Also, 'the wind - up' is a bit of an old - fashioned term but it can be used. 'The endgame' is another one, which gives a sense of the final moves in a strategic plan, much like the final parts of a story where everything is being resolved. And 'the out - come' can also be considered as a synonym as it refers to what results from all the events in the novel.
There are also 'the finale part' and 'the closing section'. These are more descriptive ways of referring to the ending of a novel. 'The end - point' is a very straightforward synonym. And 'the finishing touch' can also be used in a more metaphorical sense, as if the ending is the final touch that completes the whole work of art that is the novel.
Yes. 'Introductory story', 'prior narrative' and 'former account' are also synonyms for 'back story'. Think about a book where the events that happened before the main plot starts. All these words can be used to describe those events. For instance, in a detective novel, the detective's past cases and his own personal history which are relevant to the current case can be named with these synonyms.
Unsettled. This implies that the ending has not been made stable or final, leaving the reader with a sense of unease or anticipation. For instance, in a mystery story, if the culprit is not clearly identified and the plot is left in an 'unsettled' state, it makes the reader wonder what really happened.
Yes, there are also 'celebrated novel', 'esteemed fictional work' and 'memorable story'. A 'celebrated novel' is one that is widely known and praised. 'Esteemed fictional work' indicates that it is held in high regard in the literary community. And a 'memorable story' is something that readers can't easily forget, which is often true for classic novels as they usually have very engaging plots and characters.
Sentimental novel. This implies that the novel is full of strong emotions, especially those related to love and relationships, which is typical of a romance novel.
Yes, 'root story' can also be considered as a synonym for origin story. Consider a cultural tradition, its root story would be the one that details how that tradition started, what the initial circumstances were, and how it has evolved over time. It gives a fundamental understanding of the origin of that cultural element.
Sure. 'Traditional stories', 'heritage tales' and 'legacy stories' are also synonyms for old stories.
Sure. 'Haunting story' is one. It gives the idea that the story will stay with you, like a haunting. 'Nightmare story' is also a synonym as horror stories can be like nightmares.
Scare stories, hair - raising stories.
