Master’s or Masters: Easy Guide to Correct Usage

Master’s and masters are both correct, but they mean different things. Use master’s when referring to a degree, such as “a master’s degree,” and use masters as the plural form of “master,” such as “the chess masters competed in the tournament.”

A few years ago, I was proofreading a student’s university application when I noticed something interesting. The student wrote, “I am applying for a masters degree in Education.” It looked right at first glance. Yet something was missing.

That tiny apostrophe.

Many people struggle with master’s or masters because both versions appear online, in emails, on university websites, and even in social media posts. Some writers use them interchangeably. Others are not sure whether the apostrophe matters at all.

The confusion gets worse when you see phrases like “Masters program,” “master’s degree,” and even “Masters student.” Which one is correct? Does it depend on grammar, country, or context?

If you have ever paused while typing this phrase, you are not alone.

This guide will clear up the confusion once and for all. You’ll learn the difference between master’s and masters, discover where the terms came from, see real-world examples, avoid common mistakes, and know exactly which version to use in any situation.

Let’s settle the debate.

Master’s or Masters – Quick Answer

In most academic situations, master’s is the correct form.

Examples:

• I earned a master’s degree in Psychology.
• She is completing her master’s program this year.
• He holds a master’s in Business Administration.

Use masters when referring to more than one master.

Examples:

• Several chess masters attended the event.
• The old painters were true masters of their craft.

The apostrophe in master’s shows possession. Historically, the degree is known as a “degree of a master.”

The Origin / Background of Master’s or Masters

To understand the difference, it helps to look at the history of the word.

The word master comes from the Latin word magister, meaning teacher, chief, or person with authority. During the Middle Ages, universities awarded titles to scholars who had achieved advanced knowledge in a field.

A person who earned this qualification became a master.

Over time, people began referring to the qualification as a master’s degree, meaning a degree belonging to or held by a master.

That possessive form stayed in English.

This is why we write:

• Bachelor’s degree
• Master’s degree

Both use apostrophes because they describe a degree associated with a bachelor or a master.

Confusion arises because many universities shorten the phrase in casual writing. People often say:

• master’s
• Masters
• graduate degree

As these shortened forms became common, many writers stopped noticing the grammatical difference.
