Reffer or Refer: Which Spelling Is Correct?

English spelling has a way of catching even experienced writers off guard. A common example is the confusion between reffer or refer. Since words like preferred and occurred double the final consonant, many people naturally wonder whether refer should become reffer. Similar searches like refer or reffer, referring spelling, refers, and spelling of referring are proof that this question trips up many English learners and native speakers alike.

The good news is that the rule is easy to understand. Refer is the correct spelling, while reffer is incorrect. However, some forms of the word—such as referring, referred, and referral—do double the final r because of a standard English spelling rule.

In this guide, we’ll explain why refer is correct, why reffer is a misspelling, and how to spell every form of the verb with confidence.

Reffer or Refer: Which Is Correct?

The correct spelling is:

Refer

The incorrect spelling is:

Reffer

Refer is a common English verb that means to mention, direct someone to another source, relate to something, or send someone to a specialist or professional.

Examples

• Please refer to page 15 of the manual.
• The doctor decided to refer the patient to a specialist.
• I wasn’t referring to you.
• This report refers to last year’s sales.

In every case, the base verb is spelled refer, never reffer.

What Does “Refer” Mean?

The verb refer has several meanings depending on the context.

It commonly means:

• To mention something
• To direct someone to another source
• To point to or relate to something
• To send someone to another professional or expert

Example Sentences

• Please refer to the instructions before assembling the furniture.
• The article refers to recent scientific research.
• Your physician may refer you to a cardiologist.
• I was referring to last week’s meeting.

Why Is “Reffer” Incorrect?

Many people write reffer because they’re familiar with words like:

• Preferred
• Occurred
• Transferred

These words double the final consonant in certain forms, leading people to assume that the base word should also contain a double letter.

However, refer always has one r in its base form.

Only certain derived forms add a second r.

Why Does “Referring” Have Two R’s?

This is where the confusion usually begins.

Although the base verb is refer, the -ing form is:

Referring

Not:

Refering

English spelling rules state that when a verb:

• Ends in one vowel followed by one consonant,
• Has the stress on the final syllable,

the final consonant is doubled before adding -ing or -ed.

Since refer is pronounced:

re-FER

the stress falls on the final syllable, so the r doubles.

Examples:

• Refer → Referring
• Refer → Referred

Referring Spelling Explained

Many people search for referring spelling because they notice the extra r.

The correct spelling is:

Referring

Incorrect versions include:

• Refering
• Reffering
• Referrring

Example

• She is referring to the company’s latest policy.
• The teacher kept referring students to additional resources.

Always remember that referring contains two r’s.

What About “Refers”?

The third-person singular form is:

Refers

Examples:

• The contract refers to state law.
• She refers her clients to trusted specialists.
• This chart refers only to domestic sales.

Notice that refers does not double the r.

That’s because no suffix beginning with a vowel is added in a way that triggers the doubling rule.

Here’s a quick comparison.
