Twelve alien ships appear, and a linguist starts to live her own future as though she's remembering it. Learning a new language really can change how you think — the film just takes that idea much further.

Work through the four short activities. Each word is shown in a situation that gives its meaning away — no need to know the film yet. Say your answer out loud first, then reveal.
Denis Villeneuve's Arrival (2016), based on Ted Chiang's novella Story of Your Life. Read each part, try the quick check from memory, then discuss. (There are spoilers ahead — that's the point; we're here to talk about it.)
Twelve enormous alien ships — smooth, dark, shell-shaped — appear without warning, hovering silently above scattered sites around the world. Governments panic; nobody knows why the visitors have come or what they want. The US Army recruits Dr Louise Banks, a linguist who has worked with them before, to try to open communication, pairing her with physicist Ian Donnelly.
Inside the ship, behind a transparent barrier, Louise and Ian meet two enormous creatures they nickname "Abbott" and "Costello" — heptapods, with seven limbs radiating from a bulbous body. The heptapods don't speak the way humans do; instead, they spray circular, ink-like symbols into the air, a written language entirely separate from their spoken sounds. Painstakingly, session by session, Louise begins to learn to read and write it.
As she absorbs more of the language, Louise starts having vivid, disorienting flashes — of a little girl she doesn't recognise, sick, laughing, growing up. She assumes they are memories. She is wrong.
1. Who is recruited to communicate with the aliens, and how do the heptapods "speak"?
2. What strange experience does Louise begin to have as she learns the language?
1. Linguist Louise Banks, working with physicist Ian Donnelly; the heptapods communicate through circular written symbols rather than spoken words.
2. She starts having vivid flashes of a young girl's life, which she assumes are old memories.
As different countries translate the heptapods' message independently, a single ambiguous phrase is rendered by China as "offer weapon" and by other nations as something closer to "use tool." Trust between governments collapses; China and Russia sever their data feeds to the rest of the world, and General Shang orders his forces to prepare a strike against the ship on Chinese soil. A group of jumpy American soldiers, convinced the aliens are a threat, plants a bomb inside the ship itself.
Louise's flashes of the girl grow longer and more emotionally overwhelming, bleeding into her waking hours until they threaten to derail the mission entirely. She still cannot explain them. Meanwhile, the clock is running out: without agreement between nations on what the heptapods actually want, humanity is sliding, almost by accident, toward a war nobody has chosen.
Under enormous pressure, and now able to read the heptapods' circular script fluently, Louise confronts "Costello" directly and demands a clearer answer: why are they here, and why now?
1. Why does the ambiguous translation of the aliens' message push the world toward war?
2. What is happening to Louise as the crisis builds?
1. A key phrase is translated as "offer weapon" by China rather than something closer to "use tool," so nations stop cooperating and prepare for military action.
2. Her flashes of the unknown girl are intensifying and intruding into her waking life, though she still doesn't understand what they mean.
The heptapods finally explain themselves: they have come to give humanity their language as a gift, because in three thousand years' time, they will need humanity's help in return. Learning to think in their non-linear script, Louise realises, has begun to unlock a non-linear way of experiencing time itself — she isn't remembering the past in her flashes; she is living moments of her own future as though they were memory.
With war just hours away, Louise uses a piece of future knowledge — a private phone number, and a dying woman's last words that General Shang will one day tell her himself — to call the general directly and repeat his own wife's words back to him. Moved and shaken, Shang stands his forces down, and the other nations follow, averting the war.
Only then does Louise fully grasp what she has learned to see: she will marry Ian, have a daughter named Hannah, and Hannah will die young of an illness with no cure. She also understands that Ian, once he discovers Louise always knew this would happen, will eventually leave her over it. Knowing everything that is coming — every joy and every loss — Louise chooses to live it all anyway.
1. Why did the heptapods really come to Earth, and how does Louise prevent the war?
2. What does Louise finally understand about her own future?
1. They came to give humanity their language, because they will need humanity's help in three thousand years; Louise uses knowledge from her own future to call General Shang and quote his late wife's words, persuading him to stand down.
2. She will marry Ian and have a daughter, Hannah, who will die young; Ian will eventually leave once he learns Louise always knew. She chooses to live it anyway.
No film needs this structure more than Arrival. English lets you stand at a point in the past and describe what was, at that time, still in the future — telling a foreseen future as though it were already a memory. That is exactly how Louise experiences her own life once she learns the heptapods' language.
Read the meaning in brackets and complete the sentence.
1. When Louise first stepped inside the shell, she didn't know that this moment (change) the rest of her life. (a foreseen future, told as memory)
2. The generals on both sides (announce) a full-scale attack within forty-eight hours — until one phone call stopped everything. (a plan already in motion, later interrupted)
3. Nobody in the room realised that the quiet linguist standing before them (become) the person who saved the world. (formal, almost fated)
1. would change (future-in-the-past with would)
2. were going to announce (a plan, later interrupted)
3. was to become (formal, fated future-in-the-past)
Each sentence has the right idea but the wrong form. Write the corrected verb phrase.
1. Before she met the heptapods, Louise never imagined that learning a language (change) the way she experienced time itself. (foreseen future, told as memory)
2. Military commanders on both sides (launch) a strike that weekend — the plan was already set in motion. (a plan already in motion)
3. It was only years later that people understood: this first contact (mark) the beginning of a new age for humanity. (formal, fated)
1. would change (would)
2. were going to launch (was/were going to)
3. was to mark (was/were to)
Fill each gap with the future-in-the-past form the meaning needs. Read it aloud when you're done.
Long before she rocked her daughter to sleep, Louise already knew the shape of her whole life. She (fall) in love with a brilliant, funny physicist — and, once he learned the truth, he (leave) her. Their daughter, born into a short and radiant life, (not / survive) her twenties. Louise chose all of it anyway.
would fall · was going to leave · would not survive
Notice the pattern: would narrates the foreseen future as memory; was going to marks a plan already forming.
Carry this into the Speak tab — the whole tragedy and the whole beauty of this film live in the gap between what Louise knows would happen and what she chooses to live anyway.
Arrival is built on a real, century-old idea in linguistics — pushed, by the end of the film, a long way past what any real linguist would claim.
The theory is usually called the Sapir–Whorf hypothesis, or linguistic relativity: the idea that the language you speak shapes, to some degree, how you think and perceive the world. It's named after the American linguist Edward Sapir and his student Benjamin Lee Whorf — but, tellingly, neither man ever actually published a joint "hypothesis" together. The label was applied by later scholars, gathering their separate writings under one name only after Sapir's death in 1939.
There's a strong version: that language doesn't just influence thought but entirely determines and limits it — that you literally cannot think a thought your language has no words for. This version, often called linguistic determinism, is largely rejected by modern linguists. Multilingual speakers can hold and translate ideas across languages that supposedly shouldn't be able to contain them, which is hard to square with a strict, deterministic reading.
Then there's a weak version: that language influences habitual thought — the routine, everyday ways people notice, categorise and remember the world — in real but modest and measurable ways, without ever controlling what a person is fundamentally capable of thinking. This weaker claim is the one most linguists today take seriously, and it has genuine experimental support behind it.
In studies of colour terms, speakers of languages with fewer basic colour categories (such as Berinmo, spoken in Papua New Guinea) have shown measurably different speed and accuracy at distinguishing certain shades compared with English speakers, whose language slices the colour spectrum differently. In studies of time, the psychologist Lera Boroditsky found that Mandarin speakers, who often describe time using vertical terms, tend to reason about time vertically more readily than English speakers, who typically use horizontal, left-to-right terms. And in languages with grammatical gender — where nouns are masculine or feminine — speakers have been shown to describe the same object with subtly different adjectives depending on its grammatical gender in their language.
None of that lets anyone glimpse the future. Arrival takes this real, if modest and still debated, idea and pushes it to a fictional extreme: that mastering a truly alien, non-linear language could let a person perceive time non-linearly too. Ted Chiang, whose 1998 novella Story of Your Life the film adapts, wrote it to explore what it would mean to live a whole life knowing everything that was coming — a thought experiment, not a scientific claim. Linguists who reviewed the film generally praised its unusually careful depiction of how field linguistics actually works, while noting plainly that its central premise is a leap of imagination well beyond the real hypothesis.
This is the heart of the lesson — do it all out loud. The timer keeps you going; fill the time with detail.
Tell the story of Arrival in your own words, as if to someone who has never seen it. Move through the arc: twelve ships arrive → Louise learns the heptapods' circular language → an ambiguous translation pushes the world toward war → Louise uses knowledge of her own future to stop it → she learns the full cost and joy of the life she is about to live.
Work in at least five key words (decipher, delegation, innate, converge, ambiguous, profound, foresee, reconcile, threshold, sentient), and use would / was going to / was to when you reach the parts of Louise's foreseen future: "she would have a daughter; she would lose her."
Louise learns her whole future in advance — including a devastating loss — and chooses to live it anyway, for the sake of the joy inside it. Build an argument: is it better to know your future, even a painful one, or is it kinder never to know? Would foreknowledge free you to appreciate life more, or trap you in dread?
The film argues that learning a new way of thinking can change how you experience your own life. Is that true in your experience — has learning a language, a skill or a new way of thinking ever changed how you see the world? Make your case.
