The initial portion of the title is suggestive, often known as the implicative. Because a title is meant to be innovative and catchy, the first portion hints at the content and inspires a desire to read the book. The intriguing title is typically seen in newspapers, periodicals, or fiction works on its own. For example, "Pride and Prejudice" is an acclaimed novel by Jane Austen. A title can be considered the abstract of the work itself. Thus, the title gives readers a brief overview, or prospectus, of what they can expect from the book. Often, titles are used to attract attention or make a statement. For example, "Fifty Shades of Grey" attracted much controversy when it was first published. "Harry Potter and the Philosopher's Stone" is one of the most successful book series ever written, and "Harry Potter and the Deathly Hallows" is also one of the best-selling books of all time. These titles were chosen to grab readers' interests and encourage them to learn more about their contents. Titles can be used to distinguish books that are similar but not identical. For example, there are many different versions of Homer's "Iliad" available today because scholars continue to edit out outdated words and phrases from the original text. These edits are made to avoid repeating words or expressions within the poem.
