How should I reference an author with suffixes (like junior or senior) in their name?

Junior, Senior, the Third (III), etc. are known as suffixes.

• Place the Jr. or III after the author's first initials in the reference, and place a comma to separate the initials from the suffix (American Psychological Association, 2020, p. 286)
  • Example: Lastname, A., Jr. (year). Title of resource. Retrieved from URL
• Don't include the Jr. or III in the in-text citation: (Lastname, year, p. X).
