“Transferred” or “transfered” — one of these is a spelling error. If you’ve paused mid-sentence unsure which to use, the answer is quick: only transferred is correct.
But knowing why helps you spell dozens of similar words right without having to look them up each time.
The Correct Spelling
Transferred — with a double R — is the only standard spelling in both American and British English.
Transfered (single R) is a misspelling. It doesn’t appear in any major dictionary as an accepted variant.
Why the R Doubles in Transferred or Transfered
This is where it gets useful.
The word transfer ends in a consonant (R) preceded by a vowel (E), and the stress in the base word falls on the final syllable: trans-FER.
In English spelling, when you add a suffix like -ed or -ing to a verb that ends in a stressed consonant-vowel-consonant pattern, you double the final consonant.
So:
- trans-FER + ed = trans-FERRED ✓
- trans-FER + ing = trans-FERRING ✓
This doubling rule protects the short vowel sound. Without it, transfered would look like it rhymes with preferred written as prefered — which is also wrong for the same reason.
The Same Rule in Action
Once you see the pattern, it clicks:
| Base word | Stress | + ed | + ing |
| transfer | trans-FER | transferred | transferring |
| prefer | pre-FER | preferred | preferring |
| refer | re-FER | referred | referring |
| occur | oc-CUR | occurred | occurring |
| begin | be-GIN | — | beginning |
All of these double the final consonant because the stress lands on the last syllable.
Compare this to words where stress falls earlier:
- OF-fer → offered (no doubling — stress is not on the final syllable)
- BUF-fer → buffered (same reason)
Examples of Transferred Used Correctly
- She was transferred to the London office last spring.
- The funds were transferred into the account overnight.
- Ownership of the property was transferred to the buyer at closing.
- He transferred his university credits without losing any of them.
- The patient was transferred to a specialist unit for further care.
What About “Transferal” and “Transference”?
Two related nouns are worth knowing:
Transfer (noun) — the most common noun form. The transfer took three days.
Transferal — a valid but less common noun. The transferal of data was complete. Accepted in most dictionaries, though you’ll rarely see it outside formal or technical writing.
Transference — used mainly in psychology to describe a specific process where a patient projects feelings onto a therapist. Outside that context, transfer is the more natural choice.
None of these use the double-R form because the doubling rule only applies when you add -ed or -ing directly to the verb.
Quick Spelling Check of Transferred or Transfered
If you’re ever unsure, say the word out loud:
trans-FURRED
That emphasized, held sound at the center is exactly what the double R signals on the page. One R doesn’t carry that weight visually or phonetically.
The short version: Always write transferred. The double R follows a consistent English spelling rule — the same one behind referred, preferred, and occurred. Once the rule sticks, you won’t second-guess this group of words again.
