Masters or Master’s: Meaning, Difference, and Examples
Masters and master’s differ by a single apostrophe, but that tiny mark changes everything. Masters is a simple plural — more than one master, as in “the chess masters.” Master’s means something belongs to a master, or it names the graduate degree, as in “her master’s in physics.”
Quick Answer
| Word | Part of Speech | Main Meaning | Example |
|---|---|---|---|
| Masters | plural noun | more than one master — experts, owners, skilled people | The chess masters gathered for the final. |
| Master’s | possessive / noun (degree) | belonging to a master; or short for “master’s degree” | She earned her master’s in 2022. |
Simple rule: if you mean several people, leave the apostrophe out. If something belongs to a master — or you mean the degree — the apostrophe stays in.
What Does “Masters” Mean?
Masters is the regular plural of master. A master is someone with great skill or authority in something — a master chef, a chess grandmaster, a master carpenter. Add an s, and you’re talking about more than one of them. That’s all there is to it: no apostrophe, no special meaning.
Examples:
- The piano masters of the 19th century set a standard nobody has matched.
- Two masters of the craft ran the workshop together for forty years.
- The martial arts masters bowed before the demonstration began.
- She has studied under several masters of classical guitar.
- The old sailing masters could read the weather in the clouds.
One capitalized exception: The Masters is a famous annual golf tournament held in Augusta, Georgia. Because it’s a proper noun — the name of a specific event — it always takes the capital M.
What Does “Master’s” Mean?
Master’s uses the apostrophe for two jobs, and both are worth knowing.
1. The possessive: belonging to a master
The apostrophe-s shows ownership, the same as in “the dog’s leash.” This is the older, original sense.
- The master’s instructions were written on the back of the door.
- We waited in the master’s study while he finished his letters.
- The apprentice copied the master’s brushstrokes exactly.
2. Shorthand for “master’s degree”
This is the sense most people use. A master’s degree is the graduate degree earned after a bachelor’s — and the full name keeps its apostrophe. In everyday speech and writing, it gets shortened to just “master’s,” which works as a noun on its own.
Historically it was “the degree of a master,” which is why the possessive apostrophe stuck around. Merriam-Webster’s entry for master’s degree confirms the standard spelling — apostrophe included.
- She earned her master’s in public health last spring.
- A master’s in engineering takes about two years full-time.
- He’s applying to three master’s programs this fall.
- My master’s thesis was on medieval trade routes.
Note the lowercase m: when it means the degree, master’s is not a proper noun, so it isn’t capitalized.
Masters vs. Master’s: Key Differences
| Feature | Masters | Master’s |
|---|---|---|
| Apostrophe | never — plurals don’t take apostrophes | always — it’s possessive or degree shorthand |
| Core meaning | more than one master | belonging to a master, or the graduate degree |
| Degree use | wrong (“masters degree” is a mistake) | right (“master’s degree” is the standard form) |
| Counting | “two masters” works fine | “two master’s” doesn’t work — say “two master’s degrees” |
| Capitalization | lowercase, except the golf event “The Masters” | lowercase m when it means the degree |
Seeing the apostrophe as a signal — either ownership or the degree — makes the choice nearly automatic.
Masters or Master’s in Real Sentences
At School
Masters: “Two grandmasters visited our school for a chess workshop.”
Master’s: “My brother finished his master’s in history last spring.”
The first counts people in a room; the second names a qualification on a résumé.
At Work
Masters: “The company was founded by two masters of the brewing craft.”
Master’s: “She got a promotion right after completing her master’s in business.”
One sentence is about people with rare skills; the other is about a degree that opened a door.
In Conversation
Masters: “Those two are true masters of the barbecue.”
Master’s: “My master’s diploma is still in a tube somewhere.”
Casual or formal, the pattern holds: many experts get no apostrophe, the degree always keeps it.
Common Mistakes
Mixing up masters and master’s is one of those small errors that make writing look careless — the same way people trip over whose vs who’s when one apostrophe flips the meaning. And as woman vs women shows, plural rules have their own logic that an apostrophe can’t fix. Here are the errors that show up most:
Mistake 1: Dropping the apostrophe in the degree
❌ He earned a masters degree in finance.
✅ He earned a master’s degree in finance.
Why: the degree is historically “the degree of a master,” so the possessive apostrophe is part of the standard spelling. Without it, you’re accidentally using the plural.
Mistake 2: Pluralizing the degree wrong
❌ She holds two masters in engineering.
✅ She holds two master’s degrees in engineering.
Why: when the degree becomes countable, only the word “degree” takes the plural — the apostrophe form stays singular.
Mistake 3: Adding an apostrophe to a plain plural
❌ The master’s all agreed on the new rules.
✅ The masters all agreed on the new rules.
Why: plurals never take apostrophes. When you mean several people, the apostrophe has no job to do.
Mistake 4: Capitalizing the degree
❌ He started his Masters in Business this fall.
✅ He started his master’s in business this fall.
Why: degree names aren’t proper nouns, so they stay lowercase. The only common capitalized form is the golf tournament, The Masters.
Pronunciation
Both are pronounced exactly the same: “MASS-terz.” The apostrophe is silent, which is exactly why this mistake is so common — you can’t hear the difference, so the spelling has to carry it.
How to Remember the Difference
Picture the apostrophe as a tiny graduation cap sitting on top of the word. It only shows up for special occasions: when something belongs to a master, or when the degree itself appears. No cap, no ceremony — plain masters just means many skilled people.
Another way: the apostrophe in master’s stands in for the missing idea of ownership — “the degree of a master.” Say that phrase in your head, and the apostrophe writes itself.
- masters = plural, more than one — never an apostrophe
- master’s = possessive, or short for “master’s degree”
- The degree is lowercase: “her master’s in physics”
- The Masters (capital M) is the golf tournament — the one exception
Frequently Asked Questions
Is it masters or master’s degree?
It’s master’s degree — the apostrophe is part of the standard spelling. Writing “masters degree” treats the degree as a plain plural, which it isn’t.
What is the plural of “master’s degree”?
Master’s degrees — only “degree” becomes plural. The apostrophe stays put because each degree still belongs to the “master” tradition.
Do you capitalize master’s degree?
No. Unlike job titles or the names of schools, degree levels stay lowercase: “a master’s in biology,” “her master’s degree.” Keep the capital M for The Masters golf tournament.
Why does the degree have an apostrophe at all?
It began as a possessive phrase — “the degree of a master.” The apostrophe marks that ownership, and dictionaries have preserved it ever since.
Can “masters” ever mean the degree?
No. Masters without the apostrophe is only ever the plural of master — multiple experts, owners, or skilled people. For the degree, the apostrophe is non-negotiable.
Is “She has her masters” correct?
Not quite — write “She has her master’s.” The apostrophe signals the shortened “master’s degree,” which is what the sentence actually means.
Conclusion
Masters counts people; master’s claims ownership or names the degree. Once you hear the difference — many experts versus one graduate qualification — the apostrophe stops being a guessing game. Write the plural without it, and keep it firmly in place for the degree.
