What does "hanging indent" refer to in APA formatting?

In APA formatting, a "hanging indent" specifically refers to the structure of reference entries where the first line is flush left, and all subsequent lines in that entry are indented by 0.5 inches. This formatting style helps to visually distinguish each reference at a glance, making it easier for readers to scan through the list of citations. The flush left alignment of the first line allows it to stand out, while the indentation of the subsequent lines maintains a clean and organized appearance for the entire reference entry.

Using a hanging indent is particularly important in academic writing, as it clearly delineates where one reference ends and another begins, which is crucial for both clarity and adherence to APA guidelines. This formatting method is a significant aspect of creating properly structured reference pages, ensuring that citations are presented consistently and professionally.
