What is a suffix in a name?
A suffix in a name is a letter or group of letters after the surname (aka last name) that provides details about someone’s familial relationship (e.g., “Jr.”) or professional qualifications (e.g., “MD”).
Some of the most common name suffixes include the following:
- Jr. (short for “junior”) is for a man who has the same first and middle name as his father (e.g., Cuba Gooding Jr.).
- III (short for “the third”) is for a man who has the same given name as his father and grandfather (e.g., Randolph Severn Parker III)
- MD is an abbreviation for “medical doctor” (e.g., Sanjay Gupta, MD)
- PhD is a suffix for someone who’s earned a doctorate of philosophy (e.g., Mayim Bialik, PhD)
When a name suffix denotes a professional qualification, there’s usually a comma between the surname and the suffix. The QuillBot Grammar Checker can help you use name suffixes correctly in your writing.
