People often wonder: “flack or flak?” Both spellings appear in writing, but which one is correct?
Here’s the quick answer: “flack or flak”
- Flak (with a “k”) → Correct when talking about criticism.
- Flack (with a “c”) → Only correct when referring to a publicist.
This guide clears the confusion. You’ll learn the correct spelling, its meaning, origin, and when to use each form.

Flack or Flak – Quick Answer
Quick Answer: The correct spelling is “flak” most of the time.
Flack is used only as a slang term for publicity agent or person giving press coverage.
Examples:
- The company got a lot of flak for the new policy. (correct — negative criticism)
- She works as a flack for the movie star. (correct — publicity agent)
- He received flack from news sites. (informal but common)
- He received flak from news sites. (standard)
So:
- Flak → criticism or anti‑aircraft fire (literal or figurative)
- Flack → publicist (rare, specific)
Most people who search “flack or flak” want to know which spelling to use when talking about criticism.
The Origin of Flack or Flak
Where These Words Came From
The confusion starts in history. The word “flak” has roots in German.
- Flak (with “k”) came from the German word Fliegerabwehrkanone → flieger (aircraft) + abwehr (defense) + kanone (cannon).
→ Flak meant anti‑aircraft fire in wartime.
Because soldiers used the word so much, it moved into English as flak meaning heavy criticism (like being shot at with words). Over time, writers and speakers used flack too — sometimes by mistake.
Why Spelling Differences Exist
The confusion exists because:
- English borrowed a foreign word (Fliegerabwehrkanone).
- Learners sometimes assumed a “c” fits English spelling patterns.
- Some writers mistakenly wrote “flack” instead of “flak.”
- Flack also existed as a word with a separate meaning (publicist).
So there are two paths:
- One spelling with a standard meaning
- One spelling used but often mistaken
The result: people search “flack or flak” to know which is correct.
British English vs American English Spelling
Generally:
- Both British and American English use flak for criticism.
- Flack as criticism is informal and discouraged in formal writing.
