Unenroll or Disenroll: Which Spelling Is Correct?

Choosing between unenroll or disenroll can be confusing. Both words relate to ending enrollment, but they do not appear equally often in every type of English. 

Add British spelling, American spelling, school rules, and formal documents, and the choice becomes even less clear.

If you are writing an email to a school, filling out an online course form, or editing a professional document, you may wonder: Should I write “unenroll” or “disenroll”? You may also see “unenrol” or “disenrol” and wonder if these are mistakes.

The good news is simple: both “unenroll” and “disenroll” are established English words. “Unenroll” is a natural choice for general, modern writing, while “disenroll” is common in official, administrative, and institutional contexts. 

British English may use the single-l forms unenrol and, less commonly, disenrol.This guide explains the meaning, history, spelling, regional differences, and best usage. It also gives practical examples so you can choose the right form with confidence.

Unenroll or Disenroll  Quick Answer

Unenroll and disenroll both mean to remove someone or yourself from enrollment in a course, program, organization, or service.

For most general writing, unenroll is the easiest and most natural choice.

Examples:

• “I want to unenroll from the online course.”
• “Students can unenroll before the deadline.”
• “The university may disenroll students who do not meet its requirements.”

There is a useful difference in tone:

Word	Common use	Example
Unenroll	General, everyday, educational, digital	“I decided to unenroll from the course.”
Disenroll	Formal, administrative, institutional	“The agency may disenroll members from the program.”
Unenrol	British/Commonwealth spelling	“You can unenrol from the course.”
Disenrol	British spelling, less common	“The member was disenrolled from the scheme.”

However, unenroll does not always mean voluntary removal, and disenroll does not always mean forced removal. The distinction is mainly about usage and context, not a strict grammar rule. Merriam-Webster defines disenroll as removing a name from a roll and, more broadly, releasing someone from membership in an organization.

The Origin of Unenroll or Disenroll

Both words are built from enroll, which means to place a person’s name on an official list or register.

The history of enroll goes back to Middle English enrollen, from Old French enroller. The basic idea was to place something on a roll or list.

The two modern words add different prefixes:

• un- + enroll = unenroll
• dis- + enroll = disenroll

The prefix un- often shows reversal or removal. We see the same pattern in words such as unlock, untie, and undo.

The prefix dis- can express separation, reversal, or removal. Similar examples include disconnect, disengage, and discontinue.

That is why both words make sense. Both describe reversing or ending an enrollment.

The spelling difference also comes from the base word:

• American English: enroll
• British English: enrol

Cambridge lists enrol as the UK spelling and enroll as the usual US spelling.

This creates forms such as unenroll/unenrol and disenroll/disenrol.

British English vs American English Spelling

The main regional difference is the spelling of enroll/enrol.

American English normally uses enroll, while British English uses enrol. The same difference appears in related words such as enrollment/enrolment.

Comparison Table

Meaning	American English	British/Commonwealth English
Register	enroll	enrol
Remove from enrollment	unenroll	unenrol
Formal removal	disenroll	disenrol
Act of enrolling	enrollment	enrolment
Past tense	enrolled	enrolled
Present participle	enrolling	enrolling

Notice an important point: enrolled and enrolling keep the double l in both varieties. For example:

• US: “She enrolled last week.”
• UK: “She enrolled last week.”
• US: “She is enrolling today.”
• UK: “She is enrolling today.”

The difference is mainly in the base verb and related noun forms.

British English commonly uses single-l forms such as enrol and enrolment, while American English uses enroll and enrollment.

There is one extra wrinkle: disenrol exists in British English, but it is much less common than everyday alternatives such as withdraw or leave. Collins currently labels disenrol as a British form and marks it obsolete in its dictionary entry.

Which Spelling Should You Use?

Your audience should guide your choice.

For American English

Use unenroll or disenroll.

For general writing, unenroll is often the clearer choice:

“You can unenroll from the course at any time.”

For official policies, healthcare documents, government programs, or institutional notices, disenroll may be more appropriate:

“Members may disenroll from the plan during the permitted period.”

Merriam-Webster recognizes disenroll as a standard verb.

For British and Commonwealth English

Use enrol rather than enroll as your base spelling.

Thus, unenrol is a logical British form. It is listed as an alternative form of unenroll.

In practice, British writers may also prefer clearer phrases such as:

• withdraw from a course
• leave a program
• cancel enrollment
• remove from the register

For Global English

If your readers come from many countries, unenroll is usually easy to understand.

However, consistency matters more than choosing one word perfectly. If your website, school, company, or software uses disenroll, follow that terminology throughout.

Common Mistakes with Unenroll or Disenroll

Several mistakes appear often.

1. Writing “un-enroll”

Incorrect or unnecessary in most modern writing:
“Please un-enroll me from the class.”

Better:
“Please unenroll me from the class.”

The word is normally written as one word.

2. Using “unroll”

Unroll is a different word. It means to open or spread something that was rolled up.

“Unroll the poster.”

For ending enrollment, use unenroll or disenroll.

3. Mixing US and UK spelling

Avoid mixing:

“Please unenrol from the course.”

in a document otherwise written in American English.

If you use US English, choose unenroll. If you use British English, unenrol can fit the spelling system.

4. Assuming “disenroll” is wrong

It is not wrong. Merriam-Webster lists disenroll and defines it as removing someone from a roll or membership.

5. Assuming the two words always have different meanings

There is some overlap. Unenroll can describe voluntary withdrawal, while disenroll often appears in formal removal notices, but this is a usage tendency rather than a universal rule.

6. Using “enrolled” when you mean “unenrolled”

These words have opposite meanings:

• enrolled = registered
• unenrolled = no longer registered

Example:

“The student is enrolled in the course.”

versus:

“The student is unenrolled from the course.”

Unenroll or Disenroll in Everyday Examples

The best word can depend on the setting.

In an Email

Natural:

Subject: Request to Unenroll

Hello,
I would like to unenroll from the course before the next session. Please let me know if I need to complete a form.

In a School Notice

Formal:

Students who do not meet the attendance requirements may be disenrolled from the program.

In a News Report

Formal and institutional:

The university said it would disenroll students who failed to meet the new requirements.

The word disenroll can appear in news coverage because journalists often report official institutional language. 

Merriam-Webster noted increased attention to disenroll after a university announced that it would remove students who failed to meet a requirement.

On Social Media

A casual post would normally use unenroll:

“I finally unenrolled from that course. It was taking too much time.”

In Formal Writing

Disenroll may sound more administrative:

“The organization reserves the right to disenroll participants who fail to satisfy eligibility requirements.”

In an Online Course

User-facing software often benefits from plain language:

Unenroll from this course

This is short and easy to understand.

The available language evidence shows several clear patterns:

• Enroll/enrollment are strongly established terms in American English.
• Enrol/enrolment are standard British forms.

For everyday American English, unenroll is a clear and natural choice. Disenroll is also correct and often appears in formal, administrative, healthcare, government, and institutional writing.
