Chick-Fil-A Spelling Origin: How Did the Pronounced K Come About?
Short answer: the spelling never changed. Chick-fil-A has been spelled Chick-fil-A — capital C, lowercase f, capital A, two hyphens — since the name went into use in 1964. There was never a "Chik-fil-A" or "Chic-fil-A" period that was later corrected. If you remember one, you are in very large company, and the reason is interesting.
The record that settles it
The name is a registered US trademark, and the federal register states when it was first used in commerce:
Mark Literal Elements: CHICK-FIL-A
First Use: Jun. 01, 1964 · Use in Commerce: Jun. 27, 1964
Filing Date: Apr. 22, 1968 · Registration Date: Mar. 11, 1969
US Registration Number: 866527— USPTO, serial 72296117 (tsdr.uspto.gov/statusview/sn72296117)
That is a sworn federal filing putting the "ck" spelling in commercial use from June 1964 — three years before the first Chick-fil-A restaurant opened in 1967. So the window that a "they changed the spelling later" story needs does not exist. The spelling came first.
Where the name actually comes from
It is not the founder's surname. S. Truett Cathy's last name was Cathy, which shares nothing with "Chick-fil-A."
According to the company's own account, "fil-A" is a play on fillet — the boneless breast fillet the sandwich is built on — and the capital A is a nod to "Grade A", meaning top-quality poultry. It is worth phrasing it that way, as the company's stated explanation, because that is exactly what it is: an origin story told by the brand, not an independent finding. Stated that way, nobody can argue with it.
The real name change, which is probably what you are remembering
There is a genuine, documented name change in this history — it just is not Chick-fil-A's.
In 1946, Truett Cathy opened a small diner in Hapeville, Georgia called the Dwarf Grill. It was later renamed the Dwarf House. That is a real restaurant that really changed its name, run by the same man, and it is almost certainly the seed of the story after a few retellings.
What happened next was sequential, not a rename: Cathy developed the pressure-cooked boneless chicken sandwich at the Dwarf House, the Chick-fil-A name went into use in 1964, and the first Chick-fil-A restaurant opened in 1967 at Greenbriar Mall in Atlanta. Two different restaurant concepts by the same person — not one concept renamed.
The detail that ends the argument: the Dwarf House kept operating under its own name for decades afterwards. A company that renamed itself does not leave the old name running down the road.
So why does almost everyone remember it differently?
A few things feed it, and none of them require anyone to be careless:
- The spelling is genuinely unusual, so it gets misremembered and mistyped constantly — including by large news organisations. ABC News ran a Nightline segment in 2009 under a headline spelling it "Chik-fil-A."
- The logo draws the C as a stylised chicken, which makes the first letter read as a picture rather than a letter, and blurs the memory of the actual string.
- The logo itself has been redesigned more than once over the decades, so something visible really did change — just not the letters.
- There is a real name change in the story (Dwarf Grill → Dwarf House) that gets attached to the wrong restaurant.
In other words, the belief has honest causes. It is still not what happened.
If you need to settle this with someone
Send the trademark record above — it is a primary source, it is public, and it carries a date. If they want a second, Chick-fil-A publishes its own company history and it names the Dwarf Grill and the 1967 Greenbriar Mall opening. Photographs of old signage work too: the spelling on a 1970s storefront is the same as the spelling today.
One thing worth not claiming: the exact year the name was coined. Different sources give 1961, 1963 and 1964, because they are describing different events — the company's incorporation, the naming, and the first commercial use are three different dates. The trademark record's June 1, 1964 first-use date is the one that is documented and sworn, so it is the one to quote.
Corrected on 9 August 2026. An earlier version of this page stated that the name derived from the founder's surname, and that the restaurant was originally spelled "Chik-fil-A" before the spelling was officially changed. Both claims were false — the surname was Cathy, and the federal trademark record shows the "Chick-fil-A" spelling in use from June 1964, before the first restaurant opened. That earlier version also referred to a tweet by President Barack Obama that we could not substantiate; the claim has been removed. We would rather correct the record openly than quietly delete the page.
