Master’s Degree or Masters Degree: Quick Answer
Master’s degree is grammatically correct because it shows possession.
The degree belongs to a master (from Latin magister), not to multiple masters.
- ✅ She earned a master’s degree in economics.
- ❌ She earned a masters degree in economics.
In formal writing, education documents, resumes, and universities, master’s degree is the accepted standard.
The Origin of Master’s Degree
Historical Roots
The term master comes from the Latin word magister, meaning teacher or one who has authority. In medieval European universities, a master was someone qualified to teach others. When a student completed advanced study, they were awarded the degree of a master.
Why the Apostrophe Exists
The apostrophe in master’s degree shows possession. It literally means:
a degree belonging to a master
Just like:
- a bachelor’s degree
- a doctor’s degree
The apostrophe follows the same grammatical rule.
Why Confusion Developed
Over time, people started seeing masters as plural instead of possessive. Because English apostrophes are confusing, especially in spoken language, many writers dropped the apostrophe incorrectly. The mistake spread online, but grammar rules did not change.

Example:
- He completed a master’s degree in computer science.
