Six years of total war transformed British society—and British English along with it. World War II produced a vocabulary born of bombed cities, rationed goods, mass mobilization, and the strange intimacy of a nation under siege together. Some words came from German, borrowed with bitter irony. Others emerged from the shared experience of shelters, shortages, and survival. Many survive today, severed from their wartime meanings but carrying historical DNA. Here’s the language that Britain created and adopted during its “finest hour.”
German Borrowings
The enemy contributed words, often with ironic adoption:
Blitz
From German “Blitzkrieg” (lightning war)—the Nazi military doctrine of rapid, overwhelming force.
British adoption: The bombing of British cities became “the Blitz.” Londoners were “blitzed.” The word was taken from the enemy and owned.
Modern survival: “Blitz” now means any intensive effort. “I’m going to blitz the housework” has no wartime resonance for most speakers.
Blitzed
Originally meant bombed; expanded to mean overwhelmed or (later) extremely drunk.
Today: “I got completely blitzed last night” typically means intoxicated—the bombing metaphor faded.
Flak
From German “Fliegerabwehrkanone” (anti-aircraft gun). Pilots faced “flak” over enemy territory.
Modern survival: “Taking flak” or “catching flak” means facing criticism—far from its original lethal meaning.
Strafe
Already present from WWI but continued. German “strafen” (to punish) became English for aerial attack.
Ersatz
German for “replacement” or “substitute.” Used sarcastically for inferior wartime substitutes—ersatz coffee (made from acorns), ersatz anything.
Modern survival: “Ersatz” still means inferior substitute, though less commonly used.
The Home Front Vocabulary
Civilian life during the war developed its own language:
Blackout
The mandatory darkening of all lights to prevent enemy bombers from navigating. Blackout curtains, blackout regulations, blackout wardens.
Modern survival: “Blackout” means any loss of power or consciousness—the wartime specific meaning lost.
Shelter
Air raid shelters—public shelters, Anderson shelters (garden), Morrison shelters (indoor). “Sheltering” was nightly routine during bombing.
All Clear
The siren signal that a raid was over, safe to emerge.
Modern survival: “The all clear” signals any danger has passed.
Siren
The air raid warning. The rising and falling wail became synonymous with danger.
Dig for Victory
The government campaign to grow food. Every garden became a potential vegetable patch.
Make Do and Mend
The rationing slogan encouraging repair over replacement.
Modern survival: “Make do” remains common; the full phrase evokes wartime frugality.
Careless Talk Costs Lives
Anti-gossip campaign warning that information might reach enemy ears.
Utility
Government-approved designs for clothing, furniture, and goods—simple, functional, rationed.
Ration Book
The document controlling food and goods allocation. Everyone had one; losing it was disaster.
Spam
American tinned meat that became a British wartime staple. Love it or hate it, Spam fed the nation.
Modern survival: Besides the food, “spam” became unwanted email—apparently from Monty Python’s sketch about the inescapable presence of Spam.
Military Slang
The services developed distinctive vocabulary:
Boffin
A scientist or technical expert. The “boffins” developed radar, broke codes, designed weapons.
Modern survival: “Boffin” still means expert, particularly scientific—often affectionate, sometimes dismissive.
Prang
RAF slang for crash, damage, or hit. “He pranged the aircraft” meant a crash landing.
Modern survival: “Pranged” is still British slang for damaged, particularly vehicles.
Wizard
RAF slang for excellent. “A wizard show” meant something brilliant.
Piece of Cake
RAF slang for something easy. Originally an operation that would be simple.
Modern survival: “It’s a piece of cake” means easy—with no sense of original military context.
Bought It
Killed. “He bought it over France” meant death.
Gremlins
Imaginary creatures blamed for mechanical failures. Invented by RAF pilots.
Modern survival: “Gremlins” still means unexplained technical problems.
Kite
RAF slang for aircraft.
Wingco/Groupie
Wing Commander, Group Captain—affectionate service abbreviations.
Squaddie
British army soldier (from squadron). Still used.
Browned Off
Fed up, annoyed, disenchanted.
Modern survival: Still used in Britain for mild annoyance.
Cheesed Off
Similar to browned off—thoroughly fed up.
Jerry
German soldier or German aircraft. More neutral than “Hun.”
Yank
American. Not originally derogatory, though tone could vary.
Women’s Vocabulary
Women’s wartime roles created new terms:
Land Girls
Women’s Land Army members who worked farms while men fought.
Wrens
Women’s Royal Naval Service members (WRNS = Wrens).
WAAFs
Women’s Auxiliary Air Force members.
ATS
Auxiliary Territorial Service—women’s army branch.
Factory Girls
Women working in munitions and manufacturing.
Evacuation Language
The mass movement of children from cities to countryside:
Evacuee
Children sent to the country for safety.
Host Family/Billet
The families who took in evacuees.
Evacuation
The organized movement itself—traumatic for many children and families.
Everyday Expressions
Carrot
The government claimed carrots improved night vision—explaining radar success while hiding the technology. “Eat your carrots” propaganda persists in the belief about carrots and eyesight.
Nose to the Grindstone
Work hard—wartime ethic of continuous labor.
Keep the Home Fires Burning
WWI song revived for WWII—maintaining morale while men were away.
Churchill’s Phrases
Winston Churchill’s speeches contributed memorable language:
“Their finest hour” – facing invasion
“Never in the field of human conflict…” – praising the RAF
“We shall fight on the beaches…” – defiance speech
“V for Victory” – the campaign and gesture
These entered British cultural vocabulary permanently.
Post-War Survival
Some wartime vocabulary faded:
“Anderson shelter” is now historical
“Blackout” lost its specific meaning
“Ration book” is memory, not reality
But much survives:
“Blitz” became any intensive effort
“Boffin” remains for experts
“Piece of cake” means easy
“Gremlins” explain technology failures
“Squaddie” still describes soldiers
The Spirit in the Language
WWII vocabulary reveals wartime psychology:
Dark humor: Calling bombing raids “visits” or treating danger casually.
Understatement: “A bit of a show” for major battles.
Resilience language: “Carry on,” “keep calm,” making do.
Community vocabulary: The shared experience created shared language.
Cultural Preservation
WWII language survives through:
Films: War movies preserve and spread period vocabulary.
Memoirs: Written accounts keep words in circulation.
Anniversaries: VE Day, Remembrance—occasions for historical language.
Nostalgia: The “Blitz spirit” invoked in modern crises (like COVID-19).
Conclusion
World War II lasted six years but shaped British vocabulary for decades after. Words borrowed from the enemy, created from shared experience, and developed in military service entered everyday language.
When someone says they’ll “blitz” their homework, complains about “gremlins” in the computer, or describes something as “a piece of cake,” they’re speaking WWII British slang—even if they’ve never heard an air raid siren or seen a ration book.
That’s the nature of language: it absorbs experience, transforms it, passes it forward. The vocabulary of Britain’s war—creative, resilient, darkly humorous—became simply the vocabulary of Britain. The bombs stopped falling, but the words survived, carrying forward something of what that generation lived through.
Keep calm and carry on, indeed.
