A title can reveal many things about a story. A title may suggest a main idea or theme for text, or show some insight to a character that will be spoken about in the story. It could also introduce a symbol that the writing may follow or represent. A title is very influential to the reader because it it the first thing that they see, and it gives the first bit of information about what they will be reading. Some titles may have an entirely different meaning before you read a text versus after you read the text; therefore, it is important to analyze the title before and after reading a piece of writing.
I hope this helps! :)
