What even is APA style?
"APA" stands for "American Psychological Association." According to the American Psychological Association, "when teachers ask you to write in APA Style, they are referring to the editorial style that many of the social and behavioral sciences have adopted to present written material in the field. APA Style was first developed in 1929....Since that time, it has been adopted by leaders in many fields and has been used by writers around the world."
