Ever filled out a form and suddenly got stuck at the field that says “Suffix”? Yeah… same. The first time I saw it, I stared at my screen wondering whether it wanted some secret code, my astrological sign, or what. Eventually, I realized it was simply asking for something that appears after your name—but the confusion is super common.
If you’ve seen “Jr.” “Sr.” “III,” or even “PhD” after people’s names and aren’t exactly sure what they mean, you’re not alone. These little add-ons actually tell a lot about identity, lineage, or qualifications.
Quick Answer: A suffix in a name is a word or abbreviation added after a person’s full name to show their generation, family order, rank, or professional title. It helps distinguish people with the same name.
🧠 What Does “Suffix” Mean in a Name?
A suffix is an extra word or short label placed after someone’s name to identify something specific about them.
This can include:
- Generational titles like Jr., Sr., II, III
- Professional or academic titles like MD, PhD, Esq.
- Honorary titles like OBE or MBE
Quick Example
- Michael Jordan Jr. → means Michael is the son of someone named Michael Jordan.
- Sarah Lee, PhD → means Sarah holds a doctoral degree.
In short: Suffix = an identifier added after a person’s name.
