Have you ever paused while writing an email, essay, or professional message because you were unsure whether to write refer or reffer? You are not alone.
English spelling can be confusing, especially when adding endings changes how a word is written.
The correct spelling is refer, with one “f.” The word reffer is a common misspelling and is not accepted as the standard spelling in modern English.
However, when you add certain endings, the spelling changes: refer becomes referring or referred, with a double “r.”
In this guide, you will learn the difference between refer and reffer, understand the spelling rule, explore practical examples, and discover how to avoid this mistake in everyday writing.

What Is the Correct Spelling: Refer or Reffer?
The correct spelling is refer. It is a standard English verb used when directing someone to a source, mentioning something, or recommending a person or service.
Reffer is incorrect in standard English. Although people sometimes type it because they are unsure about the spelling rule, it should not be used in formal or informal writing.
What Does Refer Mean?
The verb refer has several common meanings, depending on the context.
- To mention something: She referred to the report during the meeting.
- To direct someone to a source: Please refer to the instructions before starting.
- To recommend someone: I can refer you to an experienced doctor.
- To send someone to a specialist: The general practitioner may refer the patient to a specialist.
Each example uses the same base word, refer, with the spelling adjusted when necessary to form a different verb tense.
Why Is Reffer Incorrect?
The spelling reffer incorrectly doubles the final “f.” The standard base form contains only one “f” and one “r” at the end: r-e-f-e-r.
For example:
- Correct: Please refer to the official guidelines.
- Incorrect: Please reffer to the official guidelines.
- Correct: I will refer my friend to your business.
- Incorrect: I will reffer my friend to your business.
Remember that the base form is refer, even though some of its grammatical forms contain a doubled consonant.

Examples of Refer in Everyday Writing
Here are some natural examples showing how to use refer correctly.
- Academic writing: Refer to Chapter 4 for additional information.
- Business communication: I would like to refer a qualified candidate for the position.
- Everyday conversation: You can refer to the map if you get lost.
- Healthcare: The doctor may refer you to a specialist.
- Customer service: Please refer to your order number when contacting support.
In each sentence, refer is spelled with one “f.” Choosing the correct spelling helps your writing appear clear and professional.
Common Mistakes to Avoid
One of the most common mistakes is assuming that refer always keeps the same final spelling when an ending is added.
Compare these forms:
- Refer correct base form.
- Referring correct present participle.
- Referred correct past tense and past participle.
- Reference correct related noun.
- Reffer incorrect spelling of the intended base verb.
The important lesson is that the spelling depends on the form of the word. Doubling a consonant in referring does not make reffer correct.

Why Does Refer Become Referring and Referred?
English spelling rules explain why refer has one “r” in its base form but two “r”s in referring and referred.
The Consonant-Doubling Rule
In English, a short verb that ends in a consonant-vowel-consonant pattern often doubles its final consonant before adding an ending that begins with a vowel, such as -ing or -ed.
For example:
- Refer → referring
- Refer → referred
- Prefer → preferring
- Prefer → preferred
- Admit → admitting
- Admit → admitted
In refer, the final consonant is “r.” When the suffix is added, the final “r” is doubled to preserve the pronunciation of the stressed final syllable.
This rule explains why referring is correct but reffer is not.
When Should You Use Refer, Referring, or Referred?
Use the form that matches your sentence’s meaning and grammatical tense.
Refer: Use it for the base form, including after modal verbs and in the infinitive.
- I will refer to the document.
- Please refer to the instructions.
- We need to refer this issue to management.
Referring: Use it for an ongoing action or as a participle.
- She is referring to the latest report.
- The email is referring to an earlier conversation.
Referred: Use it for a completed action or in passive constructions.
- He referred me to a specialist.
- The case was referred to the appropriate department.
Understanding these forms will help you avoid spelling errors without having to memorize every sentence individually.

Use a Simple Memory Trick
Remember this rule:
One “f” in refer, but double the “r” in referring and referred.

- Referring the ongoing action.
- Referred the past action.
Seeing the words side by side makes the pattern easier to remember.

Follow This Quick Spelling Checklist
Before submitting an email, essay, report, or social media post, check the following:
- Use refer when writing the base verb.
- Use referring when describing an ongoing action.
- Use referred for the past tense or past participle.
- Avoid reffer when you mean the standard English verb.
- Read the complete sentence to confirm that the verb form fits the context.
For example, write “I am referring to your previous email,” not “I am reffering to your previous email.”
The correct spelling is referring, with a doubled “r,” not a doubled “f.”
Real-Life Example: Using Refer Correctly at Work
Imagine that Sarah works as a customer support representative for an online store. A customer contacts her because a recent order has not arrived. Sarah checks the order details but discovers that the shipping issue must be handled by another department.
While drafting her response, she hesitates between refer and reffer. She wants her message to sound professional, so she checks the spelling before sending it.
Sarah writes:
“Thank you for contacting us about your delayed order. I will refer your case to our shipping department for further investigation. Our team will review the details and provide an update as soon as possible.”
Her message uses refer correctly because she is describing an action she intends to take. If she later explains what happened, she might write, “I referred the case to the shipping department.”
If she describes the action in progress, she could say, “I am referring the case to the shipping department.”
These forms demonstrate how the same verb changes according to tense and sentence structure.

Now imagine that Sarah had written, “I will reffer your case to our shipping department.” The intended meaning would probably remain understandable, but the spelling error could make the message appear less polished and professional.
This example illustrates why spelling matters in practical communication. Whether you are writing customer emails, business reports, school assignments, or everyday messages, choosing the correct form helps you communicate clearly and confidently.

These resources serve different purposes. Dictionaries establish accepted spelling and usage, while Google’s guidance helps content creators focus on reader needs and trustworthy explanations.
Why This Matters for Modern Writing
In 2026, people write across emails, messaging platforms, online forms, academic documents, and professional websites. Correct spelling helps readers understand messages and supports a polished writing style.
For this particular question, the evidence-based answer remains straightforward: refer is correct, while reffer is a misspelling of the intended verb. The related forms referring and referred follow the consonant-doubling rule.
