One way is to look at the setting of the very short story. If it takes place in a spooky old house, a name like 'The Haunted House Story' could be a good choice. Also, consider using a key object in the story for the name. Say there's a magical ring in the story, then 'The Story of the Magic Ring' would be appropriate.
Names like 'A Flash of Emotion' for a story that quickly conveys a strong feeling. 'Mini Moments' can work for a collection of short, impactful moments in a story. 'Brief Beginnings' is suitable if the story focuses on new starts.
Typically, names of short stories are italicized. This is a common convention in the world of writing and publishing to give them emphasis and make them stand out.
Focus on one key idea. For instance, if you want to write about hope, build a short story around a single image like a flower growing through a crack in the pavement.
Some great names for short stories could be 'The Lost Key', 'A Moment in Time', 'The Silent Stranger'. These names are simple yet they can pique the reader's curiosity and give a hint about the possible theme or plot of the story.
Some other names for short stories are tales, novelettes (though novelettes can be a bit longer but still in the short story family), and short fictions.
Yes, the names of short stories are typically in quotes. This is a common convention in the world of literature and publishing. It helps to give a clear indication that it's a particular short story title and not just regular text within the context.
