The Second World War wasn’t just a turning point in world history—it was a linguistic revolution. The conflict brought together people from across Britain, introduced foreign influences, and created a unique pressure-cooker environment where new words and phrases flourished. Many expressions we use today have their roots in wartime Britain.
The Melting Pot of Military Service
Before the war, most Britons rarely left their home regions. Regional dialects were strong, and a Yorkshire farmer might struggle to understand a London docker. The war changed everything.
Suddenly, millions of men and women from every corner of Britain were thrown together in barracks, factories, and air raid shelters. Regional slang spread and mixed, creating a more unified British vocabulary.
Words Born in the Trenches and Barracks
Military Slang That Entered Everyday Use
- Blitz – From German “Blitzkrieg” (lightning war), now used for any intense effort (“I’ll blitz the housework”)
- Flak – From German Fliegerabwehrkanone (anti-aircraft gun), now means criticism (“He took a lot of flak”)
- Gremlin – RAF slang for an imaginary creature that caused mechanical problems
- Snafu – “Situation Normal: All Fouled Up” (the military version used a different F-word)
- Roger – Radio code for “received,” now general acknowledgment
- Duff – Military slang for broken or useless, from “duff gen” (bad information)
RAF Slang
The Royal Air Force developed particularly rich slang, much of which entered mainstream use:
- Piece of cake – An easy task (originally a successful mission)
- Bought it / Bought the farm – Killed in action
- Wizard – Excellent, wonderful
- Prang – To crash (still used for car accidents)
- Kite – An aircraft
- Gen – Information (“What’s the gen on that?”)
- Duff gen – Bad or false information
- Good show – Well done
The American Invasion (of Language)
With American GIs stationed in Britain from 1942, British English absorbed numerous Americanisms:
- Okay/OK – Became standard British usage during the war
- Jeep – From American military vehicle designation GP (General Purpose)
- Gum – “Got any gum, chum?” became a catchphrase
- Guys – Started to be used for groups of people
- Date – As in a romantic appointment
The famous phrase “overpaid, oversexed, and over here” captured British feelings about the American presence—itself a linguistic contribution to British culture.
Home Front Language
Rationing and Making Do
- Utility – No-frills, standardized goods (“utility furniture”)
- Make do and mend – The government slogan became a philosophy
- Black market – Illegal trading
- Spiv – A black market dealer or petty criminal
- Under the counter – Goods sold illegally or secretly
- Points – Rationing allocation units
Air Raid Vocabulary
- Anderson shelter – The corrugated steel garden shelters
- Morrison shelter – Indoor table shelters
- All clear – Signal that danger has passed (now general usage)

Propaganda and Public Language
The government’s communication during the war shaped how we speak:
- Keep calm and carry on – Though rarely used at the time, it’s become iconic
- Careless talk costs lives – Created lasting awareness of information security
- Dig for Victory – Encouraging self-sufficiency
- Fifth columnist – A traitor or enemy sympathizer
- Home front – The civilian aspect of war
Enemy Languages
Some German words entered British vocabulary, often pejoratively:
- Nazi – Obviously
- Gestapo – Now used for any authoritarian group (“The grammar Gestapo”)
- Führer – Used mockingly for bossy people
- Kaput – Broken, finished
- Ersatz – Substitute, inferior replacement
Class and Social Change
The war’s social upheaval affected language too:
- Working-class slang became more acceptable as classes mixed
- Women’s entry into the workforce brought factory and military slang into domestic settings
- The shared experience created a more unified national vocabulary
- Formal speech became less dominant as practicality took over
Post-War Legacy
Many wartime expressions have outlived their original context:
- “Don’t panic!” – Dad’s Army popularised wartime attitudes
- “Spirit of the Blitz” – Referenced whenever Britain faces adversity
- “We shall fight them on the beaches” – Churchill’s words remain in national consciousness
- “Their finest hour” – Used for any great achievement
Words That Faded Away
Not all wartime slang survived:
- Whizzo – Excellent (RAF slang, now archaic)
- Bags of – Lots of (“bags of fun”)
- Smashing – Still used but less common
- Wizard prang – Excellent crash/success
- Ack-ack – Anti-aircraft fire
The Lasting Impact
World War II fundamentally changed British English by:
- Mixing regional dialects – Creating more standardized slang
- Introducing American English – Beginning the transatlantic exchange
- Democratising language – Working-class speech became more acceptable
- Creating shared references – Wartime experiences became cultural touchstones
- Accelerating informality – Crisis favored directness over formality
Conclusion
Every time you say something is “a piece of cake,” complain about taking “flak,” or describe your car as “kaput,” you’re using language forged in World War II. The conflict left an indelible mark on British English, blending regional dialects, absorbing foreign influences, and creating expressions that still resonate eighty years later.
The war generation may be passing, but their linguistic legacy lives on in everyday British speech—a testament to how language evolves in times of crisis and how shared experiences shape the words we use.
