You’re typing an email, a cover letter, or a report, and you stop mid-sentence. Does the word have one R in the middle or two? You write “refered,” and the spellcheck underline tells you something is off.
It’s an easy mistake to make, because English doesn’t always spell words the way they sound. This guide gives you the answer, the reason behind it, and a few reliable tricks so you never have to look it up again.
The Short Answer: “Referred” Is the Correct Spelling
“Referred” is correct. “Refered” is a misspelling.
“Referred” is the past tense and past participle of the verb “refer.” The word needs a double R because the verb’s stress falls on the last syllable (re-FER), and English usually doubles the final consonant before adding an ending like “-ed” or “-ing” in that situation.
The Correct Forms of “Refer”
- Present tense: refer
- Third person: refers
- Past tense: referred
- Present participle: referring
“Refering” is wrong for the same reason “refered” is wrong. If you double the R in one, double it in both.
A Quick Example
Her manager referred her to the finance team for help with the invoice.
Not “refered.” Not “reffered.” Just referred.
Why “Referred” Has Two R’s: The Doubling Rule
The double R isn’t random. It follows a spelling pattern that applies to hundreds of English verbs. Once you understand it, you can spell a whole family of words correctly without memorizing them one by one.
The Rule in Plain Language
When a verb ends in a single vowel followed by a single consonant, and the stress falls on that last syllable, you double the final consonant before adding “-ed,” “-ing,” or another suffix that starts with a vowel.
Applying the Rule to “Refer” Step by Step
- Split the word into syllables. Re-fer has two.
- Check where the stress falls. We say re-FER, with the emphasis on the second syllable.
- Look at how the word ends. It finishes with one vowel (E) followed by one consonant (R).
- Add the suffix. Because the stress is on the final syllable, the R doubles: refer + ed = referred.
Why English Doubles the Consonant
The doubling protects the vowel sound. One consonant usually signals a long vowel, and two signal a short one. Compare “hoping” and “hopping,” or “taping” and “tapping.” Without the doubled letter, the spelling would suggest a different pronunciation.
Every Form of “Refer” at a Glance
Writers usually get tripped up when they move from the base verb to a different form. This table shows each form and whether the R doubles.
| Form | Spelling | Doubled R? | Example |
| Base verb | refer | No | Please refer to the attached file. |
| Third person | refers | No | She refers to the manual often. |
| Past tense | referred | Yes | He referred me to a specialist. |
| Past participle | referred | Yes | I was referred by a colleague. |
| Present participle | referring | Yes | I’m referring to the second paragraph. |
| Noun (act of referring) | referral | Yes | We got three referrals this week. |
| Noun (person who refers) | referrer | Yes | The referrer earns a small bonus. |
| Noun (a mention or source) | reference | No | Include a reference at the end. |
| Verb from “reference” | referenced | No | The report referenced two studies. |
“Reference” and “referenced” look like relatives of “referred,” but the stress moves to the first syllable (REF-er-ence), so the R doesn’t double.
What “Refer” Actually Means
Part of getting a word right is knowing how it’s used. “Refer” has several meanings, and “referred” carries all of them.
Common Meanings of “Refer”
To Mention or Speak About Something
- During the meeting, she referred to last quarter’s results.
- The author referred briefly to his childhood in the opening chapter.
To Direct Someone to a Person or Source
- The receptionist referred him to the billing department.
- My teacher referred me to a book on the subject.
To Send a Patient or Client to a Specialist
- Her family doctor referred her to a cardiologist.
- The case was referred to a senior attorney.
To Consult or Look Something Up
- She referred to her notes before answering.
- Engineers often refer to the technical specifications during a build.
To Submit a Matter to an Authority
- The dispute was referred to arbitration.
- The bill was referred to the committee for review.
Where the Word Comes From
All of these meanings trace back to the Latin referre, which combines re- (“back”) and ferre (“to carry”). The idea of carrying something back, or carrying attention toward something, runs through every sense of the word.
Common Phrases With “Referred”
Most of the time, “referred” appears alongside a preposition. Getting those combinations right makes your writing sound polished.
Referred To
“Referred to” is the standard phrase when something is mentioned or sent somewhere.
- The book referred to several earlier experiments.
- The patient was referred to a physiotherapist.
Referred To As
Use this when you’re naming or labeling something.
- The condition is commonly referred to as “tennis elbow.”
- Throughout this agreement, the company will be referred to as “the Provider.”
The phrase “hereinafter referred to as” is a staple of contracts. It tells the reader which short name will stand in for a longer one later in the document.
Referred By
Use “by” when you want to name the person who made the introduction.
- I was referred by a former client.
- Most of our new customers are referred by existing ones.
Referred Back
This phrase describes something being sent back to where it came from.
- The proposal was referred back to the planning team.
Some style guides call “refer back” redundant, since re- already means “back.” It’s widely accepted in practice, but “refer to” is cleaner.
Active and Passive Voice
| Active | Passive |
| The doctor referred him to a surgeon. | He was referred to a surgeon. |
| My manager referred me for the role. | I was referred for the role. |
The passive version is useful when the person doing the referring isn’t the focus.
Other Words That Follow the Same Pattern
“Refer” isn’t an oddball. Many verbs that end in a stressed syllable with a single vowel plus consonant follow the same rule.
| Base verb | Stressed syllable | Past tense |
| refer | re-FER | referred |
| prefer | pre-FER | preferred |
| defer | de-FER | deferred |
| confer | con-FER | conferred |
| infer | in-FER | inferred |
| transfer | trans-FER | transferred |
| occur | oc-CUR | occurred |
| admit | ad-MIT | admitted |
| submit | sub-MIT | submitted |
| regret | re-GRET | regretted |
| control | con-TROL | controlled |
If you can write “occurred” or “preferred” correctly, you already understand “referred.”

When the Final Consonant Does Not Double
If the rule is so consistent, why do words like “offered” and “differed” have only one R? Because the doubling rule only applies when the stress falls on the final syllable.
Verbs With Stress on the First Syllable
| Base verb | Stress pattern | Past tense |
| offer | OF-fer | offered |
| differ | DIF-fer | differed |
| suffer | SUF-fer | suffered |
| gather | GATH-er | gathered |
| answer | AN-swer | answered |
| enter | EN-ter | entered |
Say them aloud and you’ll hear the difference. We say “OFF-er,” so we write “offered.” We say “re-FER,” so we write “referred.”
Why “Reference” Doesn’t Double
When you add “-ence” to “refer,” the stress shifts to the first syllable: REF-er-ence. Since the stress is no longer on “fer,” the R stays single. The same shift happens in related words:
- prefer → preference (not “preferrence”)
- confer → conference (not “conferrence”)
- infer → inference (not “inferrence”)
- defer → deference (not “deferrence”)
Exceptions and Oddities
- Referable and referrable. Both appear in dictionaries. The stress shifts in “referable” (REF-er-a-ble), so the single-R form is more common.
- Preferable and transferable. These take a single R for the same reason.
- Referral. This noun keeps the double R because the stress stays on the second syllable (re-FER-ral).
Reference, Referral, Referrer, and Referee
“Refer” has many relatives, and they’re easy to mix up.
Reference
A reference is a mention, a cited source, or a person who vouches for you.
- Add a reference to the study in your footnotes.
- She listed two former managers as references on her résumé.
As a verb, “reference” means to mention or cite something: “The article referenced three government reports.” Some traditional style guides prefer “refer to,” but “reference” is widely accepted in business and academic writing.
Referral
A referral is the act of sending someone to another person or place, or the person who is sent.
- The clinic only accepts patients with a referral.
- Our referral program gives customers a discount for bringing in friends.
Referrer
A referrer is someone who makes a referral.
- The referrer received a bonus when the new hire completed ninety days.
In web analytics, a referrer is also the website that sent a visitor to your page.
The “Referer” Quirk in Web Code
If you’ve worked with websites, you may have seen “Referer” with one R in the middle. That spelling is a long-standing quirk of the HTTP specification. The early authors misspelled the word, and the error was kept for compatibility. In ordinary writing, the correct spelling is still referrer.
Referee
A referee is a person who judges a game or dispute, or someone who vouches for a job applicant.
- The referee blew the whistle.
- Please list one referee from your last job.
The single R here is correct because the word ends in “-ee,” not in a single vowel plus consonant, so the doubling rule doesn’t apply.
Common Misspellings and How to Spot Them
| Incorrect | Correct | What went wrong |
| refered | referred | Missing the doubled R |
| refering | referring | Missing the doubled R |
| reffered | referred | Doubled the wrong letter |
| referd | referred | Dropped letters |
| referal | referral | Missing the doubled R |
| referrel | referral | Wrong vowel before the final L |
| referrence | reference | Doubled R where the stress shifts |
| preferrence | preference | Same stress-shift error |
Why These Errors Happen
- Pronunciation hides the double R. The two Rs blend into one sound, so your ear doesn’t tell you there are two.
- Overcorrection. Writers who learn “referred” has a double R sometimes apply it to “reference” too.
- Typing speed. It’s easy to skip a repeated letter on a keyboard.
A Quick Self-Check
- Does the word end in a stressed syllable? (Say it aloud.)
- Does it end in one vowel plus one consonant?
- Does the suffix start with a vowel, like “-ed” or “-ing”?
If all three answers are yes, double the consonant.
American and British English: Is There a Difference?
No. Both varieties spell the word referred, and both use referring, referral, and referrer.
British and American English do split on some doubling rules. British English writes “travelled” and “cancelled,” while American English usually writes “traveled” and “canceled.” Those differences involve verbs with stress on the first syllable, where doubling isn’t required by the rule. “Refer” isn’t in that group, so you can use “referred” confidently whether you’re writing for readers in London, Toronto, Sydney, or New York.
Easy Ways to Remember the Spelling
Tie It to Words You Already Know
You almost certainly spell “occurred” correctly. It has the same stress pattern as “referred.” The same goes for “preferred,” “submitted,” and “controlled.”
Say It With the Stress
Say “re-FER” out loud with a strong beat on the second syllable. That heavy final syllable is your cue to double the letter.
Use the “-ence” Test
If the word ends in “-ence,” the R stays single: reference. If it ends in “-ed,” “-ing,” “-al,” or “-er” after the stressed syllable, the R doubles: referred, referring, referral, referrer.
Don’t Rely Only on Spellcheck
Spellcheck will flag “refered” and suggest “referred,” which helps. But it can miss typos inside technical terms and won’t catch a wrong word used correctly spelled. A quick manual check takes two seconds.
“Referred” in Professional Writing
A typo in a casual text is forgivable. In a job application or a legal document, it can undermine trust.
Emails and Business Correspondence
- “As referred to in my previous message, the deadline is Friday.”
- “I was referred to you by Maria Hassan.”
- “Please refer to the attached document.”
Job Applications and Hiring
- “I was referred by a current employee.”
- “Employee referral bonuses are paid after ninety days.”
A person who vouches for you is a reference in the United States and often a referee in the UK and Australia.
Healthcare
- “The patient was referred for further testing.”
- “A referral from your primary physician is required.”
“Referred pain,” which is pain felt away from its source, is a standard medical term and is always spelled with the double R.
Legal and Contract Writing
Legal documents lean heavily on the phrase “referred to,” as in “The parties are collectively referred to as ‘the Parties.'” A spelling mistake here looks careless, so proofread.
Academic Writing
- “The study refers to data collected in 2019.”
- “All sources are referenced in the bibliography.”
- “As referred to earlier, the sample size was limited.”
Many academic style guides prefer “cited” for formal source citations and “referred to” for passing mentions.

The Rule in One Line
Double the final R when you add a suffix to “refer,” because the stress falls on the last syllable. Don’t double it in “reference,” because the stress moves.
Conclusion
The answer to referred or refered is clear: “referred” is correct, and “refered” is a misspelling. When a verb’s stress falls on its last syllable and it ends in a single vowel plus a single consonant, the final consonant doubles before “-ed” or “-ing.” That’s why we write “referred,” “referring,” “preferred,” and “occurred.”
When the stress moves earlier, as in “reference” or “offered,” the doubling disappears. American and British English agree on all of these spellings. If you’re ever unsure, say the word aloud, listen for the stress, and compare it to “occurred.”
