Here are the ten words you'll meet, grouped into four short activities. Do each one out loud and commit to a guess before you reveal — the answer only confirms your thinking.
Read each sentence aloud. From the situation alone, say what the bold word means — then reveal.
Say the missing word out loud before you reveal. The first letter is given to help you.
Decide whether the given word is close in meaning (synonym) or opposite (antonym) to the bold word — then reveal.
These two words almost always travel with a partner word. Say the whole chunk aloud, then reveal.
Read each part. After it, there's a quick comprehension check (try the questions from memory first), then one thing to discuss.
The Bermuda Triangle is not a place you can find on any official map. It is a rough triangle of the western Atlantic, drawn between three points — Miami in Florida, the island of Bermuda, and Puerto Rico — covering perhaps half a million square miles of open, heavily travelled sea. For most of history it was simply ocean. What turned it into a legend was a single afternoon in December 1945.
On 5 December 1945, five US Navy torpedo bombers, known together as Flight 19, took off from Florida on a routine training exercise. The leader, an experienced pilot, radioed that his compasses had failed and that he could no longer tell which way the coast lay. Hour by hour the calm messages turned anxious. The planes, which were low on fuel and lost over darkening water, were never seen again. Worse still, one of the flying boats sent out to search for them also vanished, apparently exploding in mid-air.
Fourteen airmen were lost in Flight 19, and thirteen more in the aircraft that went to find them. The Navy's final report could not settle on a cause, and at one point recorded that the planes had disappeared "as if they had flown to Mars." That single haunting phrase, more than anything, planted the idea that this stretch of ocean was somehow different from all the rest.
1. Where are the three points that mark out the Bermuda Triangle?
2. What happened to Flight 19, and what made the story even stranger?
1. Miami (Florida), the island of Bermuda, and Puerto Rico — a large triangle of the western Atlantic.
2. Five Navy bombers on a training flight got lost after their compasses failed and were never found; then a rescue aircraft sent to look for them also disappeared.
Flight 19 was not the first loss in these waters. In 1918 the USS Cyclops, a huge Navy cargo ship carrying more than three hundred people and a heavy load of ore, sailed from the Caribbean towards Baltimore and was never heard from again. There was no distress signal, no wreck, no debris — one of the largest losses of life in US naval history outside of combat, and still unexplained. Other ships and planes were lost in the region across the decades, some with equally little trace.
The name itself came later. In 1964 a magazine writer first called the region "the Deadly Bermuda Triangle." Then, in 1974, an author named Charles Berlitz published a bestselling book that gathered every disappearance together and wrapped them in mystery — hinting at strange forces, lost civilisations, even the sunken city of Atlantis. The book, which sold in enormous numbers, fixed the legend in the public mind for good.
There was, however, a problem with the way the story was told. Writers who wanted a good mystery tended to exaggerate. They left out the storms, ignored the ordinary explanations, and sometimes listed ships that had actually sunk far outside the Triangle — or that had never existed at all. The legend, in other words, was partly built by the very people who were selling it.
1. What was the USS Cyclops, and why is its loss so striking?
2. How did books and magazines help turn the region into a worldwide legend?
1. A huge US Navy cargo ship that vanished in 1918 with over three hundred people aboard, leaving no signal and no wreckage — still unexplained.
2. A 1964 magazine article named it, and a 1974 bestseller by Charles Berlitz collected the disappearances and hinted at strange forces, spreading the legend widely.
When researchers looked hard at the records, the mystery began to shrink. The insurance market Lloyd's of London, which tracks losses at sea worldwide, found that ships are lost in the Triangle at about the same rate as in any other busy, stormy stretch of ocean. There is, statistically, nothing unusual to explain.
And the individual explanations are not exotic at all. This region sits directly in the path of the Gulf Stream, a fast, warm current that can sweep wreckage away and erase all trace of an accident within hours. The area is prone to sudden, violent storms and to waterspouts that can appear with little warning. It is one of the most heavily travelled corners of the ocean, so — simply by the numbers — more traffic means more accidents. Add human error, mechanical failure and, for Flight 19, a lost and disoriented crew, and each case starts to look ordinary.
One more idea is sometimes raised: pockets of methane gas released from the seabed, which in theory could reduce the density of the water and cause a ship to lose buoyancy. It is a genuine scientific possibility, though there is little evidence that it has ever sunk a vessel here. Today most experts are firmly sceptical that the Triangle is dangerous at all. The deepest mystery, perhaps, is not why the ships vanished — but why we so badly want the ocean to be haunted.
1. What did Lloyd's of London find when they studied losses in the Triangle?
2. Name two natural explanations that scientists give for the disappearances.
1. That ships are lost there at roughly the same rate as in any other busy, stormy part of the ocean — nothing statistically unusual.
2. Any two of: the fast-moving Gulf Stream that sweeps away wreckage; sudden violent storms and waterspouts; heavy traffic meaning more accidents; human error; and, more speculatively, methane gas from the seabed.
This is a story full of particular ships, flights and theories — so you constantly need to say which one you mean. That is exactly what relative clauses do: they add information about a noun using words like who, which, that, whose and where.
Complete each sentence with who, which, whose or where.
1. Flight 19 was the squadron disappeared during a training exercise.
2. The pilots, compasses had failed, could not find the coast.
3. Bermuda is the island one corner of the Triangle lies.
1. which (or that) (a thing, defining)
2. whose (possession — "the pilots' compasses")
3. where (a place)
Decide whether each clause is extra information. Write commas (and where they go) or write no commas.
1. The USS Cyclops vanished in 1918 carried more than three hundred people. (the clause: which vanished in 1918)
2. Any ship sinks in the Gulf Stream can be swept far away. (the clause: that sinks in the Gulf Stream)
3. Charles Berlitz wrote the bestseller made the legend famous. (the clause: who wrote the bestseller)
1. commas — non-defining: "The USS Cyclops, which vanished in 1918, carried…" (the ship is already named).
2. no commas — defining: "Any ship that sinks in the Gulf Stream…" (it tells you which ships).
3. commas — non-defining: "Charles Berlitz, who wrote the bestseller, made…" (the person is already named).
Combine each pair into one sentence. Punctuate carefully, then read it aloud.
1. The Gulf Stream is a warm current. It flows straight through the region. → The Gulf Stream, the region, sweeps wreckage away.
2. Lloyd's of London studied the losses. It tracks shipwrecks worldwide. → Lloyd's of London, worldwide, found nothing unusual.
3. Writers exaggerated the story. They wanted a good mystery. → The writers a good mystery exaggerated the story.
1. which flows straight through (non-defining, commas)
2. which tracks shipwrecks (non-defining, commas)
3. who wanted (defining, no commas)
Hold on to these — you'll need them in the Speak tab, where naming exactly which ship, flight or theory you mean is half the challenge.
You've read the story and you have the words — so now the real thing is within reach. There's a full podcast episode that tells this story in much greater depth, in natural, real-speed English. It's optional: the lesson stands on its own without it.
From the Noiser podcast network. Hosted by historians, roughly 50 minutes. Open Spotify and search "Short History Of The Bermuda Triangle" to find the episode.

Tell the story of the Bermuda Triangle in your own words, as if to someone who has never heard of it. Move through the arc: a stretch of the Atlantic between Miami, Bermuda and Puerto Rico → the loss of Flight 19 in 1945 → the earlier disappearance of the USS Cyclops → the books that turned it into a legend → the science of storms, the Gulf Stream, traffic and human error.
Name things precisely: use defining and non-defining relative clauses ("the flight that vanished", "the Gulf Stream, which flows through the region"), and work in at least five key words (stretch, disappear, debris, compass, legend, cursed, current, explanation, exaggerate, debunk).
The evidence points to storms, currents and human error, yet millions still believe the Triangle is dangerous. Which do you find more convincing — the mystery or the science? Build an argument, and decide why you think legends like this survive even when the facts contradict them.
Tell a story in the same spirit — a real mystery, a strange disappearance, or a legend from your own country. Lean on the grammar: name the person who disappeared, the place where it happened, the ship or plane that was never found.
