🧵 Lesson 3.2: Cohesion — Reference, Substitution & Ellipsis

Fluent English rarely repeats itself. Instead of naming the same thing twice, it points back to it, swaps in a shorter stand-in, or simply leaves out what the listener can already supply. These three quiet devices — reference, substitution, and ellipsis — are the thread that stitches sentences into a smooth, economical whole. Master them and your English stops sounding like a list of separate statements and starts flowing like the writing and speech of a native.

📚 What You'll Learn

By the end of this lesson, you will be able to:

Use reference words (pronouns, this/that/these/those, such, the former/the latter) to link cleanly across sentences
Use substitution (one/ones, do/do so/do it, so/not) to avoid clumsy repetition
Use ellipsis — leaving recoverable words out — naturally and correctly
Combine all three to write and speak with genuine cohesion, judging the register each device suits

⏱️ Estimated Time: ~60 minutes

🎯 Project: Take a deliberately repetitive text and rewrite and deliver it cohesively using reference, substitution, and ellipsis — then speak at length on a topic, sustaining smooth cohesion throughout.

In This Lesson

The Thread Between Sentences

Compare two versions of the same idea:

❌ "The committee rejected the proposal. The committee felt the proposal was too expensive. The committee will review a new proposal next month, and the committee hopes the new proposal will be cheaper."

✅ "The committee rejected the proposal; they felt it was too expensive. They'll review a new one next month and hope it will be cheaper."

Same information, radically different effect. The second version reads like a person thinking, not a database repeating fields. What does the work is a set of cohesive devices — small words that let you avoid naming things twice while keeping the meaning perfectly clear.

This lesson covers the three most important families:

Reference — pointing to something mentioned elsewhere (it, they, this, such, the latter)
Substitution — replacing a word with a shorter proform (one, do so, so)
Ellipsis — omitting words the listener can recover (I'd love to ___)

🧠 Mindset

Cohesion is a plateau-breaker. Many advanced learners are grammatically flawless yet sound faintly stilted — and the culprit is almost always repetition they don't hear, because in their first language the same repetition may be normal. The gains here are invisible from the inside: you won't feel more fluent, but your listeners will suddenly find you easier and more pleasant to follow. Trust the process; polish this layer and everything above it sounds better. 🌱

Reference: Pointing Back & Forward

Reference uses a word to point at something identified elsewhere — usually earlier in the text (anaphoric), occasionally later (cataphoric). The reader reconstructs the meaning by looking to what the reference word points at, so it must be unmistakably clear what that is.

Device	Points to	Example
Pronouns it, they, them, one	a noun already named	The report is late; it needs another week.
this / that these / those	a thing — or a whole idea/clause	House prices rose sharply. This surprised economists.
such such (a) + noun	"of that kind / that degree"	The contractor ignored every safety warning. Such behavior is indefensible.
the former / the latter	the first / second of two earlier items	We can fly or take the train; the former is faster, the latter cheaper.
the above / as follows	text before / after (formal, written)	For the above reasons, the claim is rejected. The steps are as follows: …

The most sophisticated move here is reference to a whole clause or idea, not just a noun. Notice how this below scoops up an entire preceding statement:

"Staff turnover doubled in a single year. This — more than any single decision — reshaped the team."

"The device runs for two days on one charge. That alone justifies the price."

⚠️ Keep the reference unambiguous

The great danger of it, this, and they is a vague or double antecedent — where the reader can't tell what you're pointing at:

❌ "Sales fell and the CEO resigned, which shocked the board. It was unexpected." (What was — the fall, the resignation, or both?)
✅ "…The resignation was unexpected." (Add a summary noun after this/that to pin it down: "This decision…", "This collapse…".)

💡 The reliable C1 fix is this/that + a summarizing noun ("this trend", "such a move", "these findings"). It both refers back and tells the reader how to interpret what came before.

💡 Register note

The former / the latter, such (as a determiner: "such a claim"), the above, and as follows all lean distinctly formal and written — at home in essays, reports, and legal or academic prose. In casual speech they can sound stiff or pompous; there you'd more naturally say "the first one / the second one" or "that kind of thing".

Substitution: Shorter Stand-Ins

Substitution replaces a word or phrase with a short "proform" that stands in its place — so you keep the grammar but drop the repeated content. Where reference points outward to a real-world thing, substitution swaps in a placeholder within the wording.

one / ones — for countable nouns

Instead of	Say
"I'll take the red ~~jacket~~."	I'll take the red one.
"The old ~~chairs~~ are nicer than the new ~~chairs~~."	The old ones are nicer than the new ones.
"Which ~~apartment~~ do you prefer?"	Which one do you prefer?

⚠️ One/ones substitutes for countable nouns only. For uncountables, use nothing or some: "Is there any coffee? — Yes, there's some" (not "a coffee one").

do / do so / do it / do that — for a verb phrase

Form	Use / register	Example
do (auxiliary)	after comparisons & in tags — very common	She works harder than I do. / He passed, and so did she.
do so	replaces a whole verb phrase; formal, written	Please sign the form. If you fail to do so, your application lapses.
do it / do that	a specific, concrete action; neutral/spoken	I promised to call, and I did it / did that the next morning.

💡 Do so vs do it

Do so is impersonal and often refers to a general or previously stated action — the mark of formal, careful prose ("Applicants must register by Friday; those who fail to do so…"). Do it / do that feels more concrete and conversational, pointing at one specific deed. Note too that do so doesn't replace stative verbs: we don't say "She knows the answer and I do so too" — there you'd use do alone: "…and I do too."

so / not — for a whole clause

After reporting or thinking verbs such as think, believe, hope, expect, suppose, guess, imagine, be afraid, we use so (positive) or not (negative) to stand in for an entire that-clause.

Full form	Substituted
"Is it raining?" — "I think ~~it is raining~~."	"I think so."
"Will he pass?" — "I hope ~~he won't fail~~."	"I hope not." / "I hope so."
"Are we late?" — "I'm afraid ~~we are late~~."	"I'm afraid so."

Two verbs form the negative differently. Think, believe, suppose, imagine, expect usually negate the verb ("I don't think so"), while hope and be afraid take not ("I hope not", "I'm afraid not"). ✅ Both "I don't expect so" and "I expect not" occur, but "I don't hope so" is unnatural.

Ellipsis: Leaving Words Out

Ellipsis is the omission of words that the listener can recover from context. Far from being lazy, it's the natural rhythm of fluent English: repeating every recoverable word sounds labored and oddly emphatic. The rule of thumb is simple — leave out what would only be echoed, keep what carries new information.

Where	Full form → elided
after and / but / or	She can sing and ~~she can~~ dance. / He was tired but ~~he was~~ happy.
after auxiliaries	I haven't finished, but Sam has ~~finished~~. / You could help — you just won't ~~help~~.
after to (infinitive)	"Are you coming?" — "I'd love to ~~come~~." / I didn't want to, but I had to go.
in comparatives	It cost more than I expected ~~it to cost~~. / She's taller than he is.
reduced clauses (subject + aux)	When ~~you are~~ in doubt, ask. / Though ~~he was~~ exhausted, he carried on.

Watch the same idea with and without ellipsis:

❌ "I wanted to help, and I would have helped, but I couldn't help because I was away."

✅ "I wanted to help, and I would have, but I couldn't — I was away."

⚠️ Keep the right anchor word

Ellipsis after an auxiliary or to requires that the anchor stays behind so the omission is recoverable:

✅ "She hasn't read it, but I have." — the auxiliary have holds the elided verb.
❌ "I'd love." → ✅ "I'd love to." — to must remain.
⚠️ Don't over-elide across a change of subject or tense where the listener can't reconstruct the words: keep enough to be recoverable.

Bringing It Together

In real English these devices don't take turns — they work simultaneously, sentence after sentence. Fluent speakers deploy them constantly to stay economical and cohesive; learners who dutifully repeat full nouns and verbs are grammatically correct but sound stilted.

Before: repetitive

"I applied for two jobs. The first job was in Berlin and the second job was in Madrid. I preferred the Madrid job because the Madrid job paid more. My friend told me to take the Madrid job, so I took the Madrid job. I hope I got the Madrid job — I really hope I got the Madrid job."

After: cohesive

"I applied for two jobs — one in Berlin, the other in Madrid. I preferred the latter because it paid more. My friend told me to take it, so I did. I hope I got it — I really hope so."

The rewrite is about a third shorter (59 words → 39) and reads as natural, confident English. Nothing is lost; everything repeated is now pointed to, substituted, or left out.

Listen to how densely a natural conversation packs these in:

A: Did you finish the two reports?
B: The short one, yes; the long one, not yet.
A: Will it be ready by Friday?
B: I think so. I meant to start it yesterday, but I didn't get to.
A: Can you send me the figures?
B: I'll do so this afternoon — well, I'll try to. Such requests always take longer than they look.

I think so / I hope not I'm afraid so the red one / the big ones …and so did I if you fail to do so I'd love to the former … the latter such a decision / such behavior This raises a question… for the above reasons

💡 Register at a glance

Ellipsis and everyday substitution (one, do it, I think so) are the pulse of natural speech and informal writing. The more formal reference devices — the former/the latter, such, the above, as follows, do so — belong to written and academic register. Choose the device that matches the moment: cohesion is only elegant when it fits the tone.

🔊 Hear It & Repeat — Model Sentences

Listen to each model sentence, then say it back. Use the 🎧 Audio control (bottom-right) to choose a UK or US voice and slow the speed down. These five sentences weave reference, substitution, and ellipsis into a seamless thread.

I've read both reports, and this one is by far the more thorough.
She wanted the red coat, but her sister chose the blue one.
Some people enjoy public speaking; others dread it.
He promised he would help, and he did.
I could have called earlier, but I didn't want to.

Practice & Project

🏋️ Exercise 1: Replace the repetition

Objective: Rewrite each, replacing the underlined repeated element with a reference or substitution word from the brackets.

"Do you want the big suitcase or the small suitcase?" → "…or the small ?" (one/ones)
"You should apologize. If you don't apologize, she'll never forgive you." → "…If you fail to , she'll never forgive you." (do so)
"Is the deal going ahead?" — "I believe ." (so/not)
"He insulted a guest in public. That kind of behavior is unacceptable." → " behavior is unacceptable." (such)
"We considered London and Tokyo; we chose Tokyo." → "…we chose ." (the former/the latter)

✅ Answer

1. …the small one? · 2. If you fail to do so, … · 3. I believe so. · 4. Such behavior is unacceptable. · 5. …we chose the latter.

🏋️ Exercise 2: Apply ellipsis

Objective: Cross out the redundant words to make each sentence natural (write the trimmed version).

She wanted to come, but she couldn't come.
I haven't seen the movie, but my brother has seen the movie.
"Would you like to join us?" — "I'd love to join you."
He was poor but he was honest.
The trip cost far more than we had expected it to cost.

✅ Answer

1. She wanted to come, but she couldn't. · 2. I haven't seen the movie, but my brother has. · 3. "I'd love to." · 4. He was poor but honest. · 5. …far more than we had expected (it to). (Natural: "…more than we had expected.")

🏋️ Exercise 3: Fix the faulty reference

Objective: Each sentence has an ambiguous, missing, or wrong cohesive device. Correct it.

"The teacher praised the student's essay, and it made her proud." (What is "it"? Make it clear.)
"There's still some milk if you want a milk." (uncountable — fix the substitution)
"Are you coming?" — "I don't hope so." (fix the so/not choice)
"He resigned suddenly, which everyone found strange. This was in March." (vague "this" — pin it down)

✅ Answer

1. "…and the praise made her proud." (or "…and this recognition made her proud" — replace vague it with a summary noun). · 2. "…if you want some." (one can't substitute an uncountable noun). · 3. "I hope not." (hope takes not, never "don't hope so"). · 4. "The resignation came in March." (swap vague this for a summarizing noun phrase so it can't point at "which everyone found strange").

🎯 Your Project: Repetitive → Cohesive

A two-part task: first rewrite a clunky text, then speak at length keeping cohesion smooth.

(4 min) Take a repetitive source — write your own deliberately clumsy paragraph (like the "Before" box above), or lift the driest paragraph you can find from a manual, terms-and-conditions page, or your own old writing.
(8 min) Rewrite it cohesively. Consciously introduce at least one reference device, one substitution device, and one ellipsis. Aim to cut the length noticeably without losing meaning.
(5 min) Now deliver your rewrite aloud — to a partner or into a recorder — and keep it flowing; don't read stiffly.
(5 min) Then speak unscripted for two minutes on a topic you know well (your field, a recent news story, a place you love). Your only mission: never repeat a full noun or verb phrase you could point to, swap out, or leave out.
Partner/group option: Swap "Before" paragraphs with a partner, rewrite each other's, then read both versions aloud and compare which cohesive choices sounded most natural — and whether any tipped into too compressed to follow.

✅ Project Completion Checklist

☐ My rewrite is noticeably shorter than the repetitive original
☐ I used a reference device (this/that + noun, such, the former/latter, or a pronoun)
☐ I used a substitution device (one/ones, do so/do it, or so/not)
☐ I used ellipsis at least once, keeping the anchor word
☐ Every reference is unambiguous — a listener knows exactly what each word points to
☐ In my spoken stretch, I avoided repeating full nouns/verbs I could have replaced

Tips & Common Mistakes

✅ Do's

Anchor a vague this/that/it with a summarizing noun ("this trend", "such a move") whenever the antecedent is a whole idea.
Match the device to the register: do so, such, the latter for writing; do it, one, I think so, and ellipsis for speech.
When you catch yourself about to repeat a noun or verb, pause and ask: can I point to it, swap it, or drop it?

❌ Common Mistakes

⚠️ Watch Out

Ambiguous reference: "…which shocked everyone. It was unexpected." — reader can't tell what it is. → Add a noun: "The decision was unexpected."
"one" for uncountables: "a bread one" / "a coffee one" ❌ → use some or nothing.
"I don't hope so": ❌ → hope and be afraid take not: "I hope not", "I'm afraid not".
Deleting the anchor: "I'd love." / "but Sara." ❌ → keep to or the auxiliary: "I'd love to", "but Sara has".
Over-formal cohesion in speech: "the former… the latter" in casual chat can sound pompous → "the first one… the second one".

✍️ This lesson's prompt: Find a paragraph you wrote recently and hunt for repetition you didn't notice at the time. Rewrite it using reference, substitution, and ellipsis, then note beside each change which device you used and why — and whether the register you chose fits the text. At C1, learning to hear your own repetition is the real skill; naming your fixes is how you train that ear.

📝 Lesson Summary

🎓 Key Takeaways

Reference points to something elsewhere: pronouns, this/that (even for whole ideas), such, the former/the latter, the above. Keep it unambiguous — anchor a whole-idea reference with a summarizing noun.
Substitution swaps in a proform: one/ones (countable nouns), do/do so/do it (verb phrases), so/not (clauses after think/hope/be afraid).
Ellipsis omits recoverable words after and/but/or, after auxiliaries, after to, and in comparatives — but keeps the anchor word.
Register: ellipsis and everyday substitution suit speech; formal reference (such, the latter, do so, as follows) suits writing.

🎉 What You've Accomplished

You've picked up the invisible thread that turns a string of separate statements into flowing, economical English. This is one of the least-taught yet most transformative layers of advanced fluency: the difference between a speaker who is correct and one who is genuinely easy and pleasant to follow. 🎉

❓ Common Questions at This Stage

What's the real difference between reference and substitution?

Reference points out to an entity in the world or discourse — it, they, and this send you looking for the actual thing they identify. Substitution stays inside the wording, replacing a repeated word with a placeholder of the same grammatical class: one for a noun, do so for a verb phrase, so for a clause. In practice they overlap and cooperate; you rarely need to label which is which — you just need to stop repeating.

Is ellipsis ever wrong or too informal for academic writing?

Ordinary ellipsis (after auxiliaries, to, and coordinators) is fine and common in all registers — "the results were significant; the controls were not" is perfectly academic. What's informal is conversational ellipsis that drops subjects or auxiliaries ("Seen it?", "Told you") — save that for speech and dialogue.

How do I stop my own repetition when I can't hear it?

Read your writing aloud, or better, let a day pass and reread it. Repetition that was invisible while composing leaps out on a cold read. Over time the ear trains itself: you start feeling the pull to say "the latter" or "I think so" before you've consciously decided to — which is exactly when cohesion has become instinctive.

🔭 Looking Ahead

Cohesion keeps your meaning clear and connected; next we soften and shade it. In Lesson 3.3, you'll explore hedging, vague language, and diplomatic English — the art of qualifying claims, sounding tentative on purpose, and delivering hard messages with tact. Together with cohesion, these round out a truly polished, socially deft advanced voice.

✅ Before the Next Lesson

Rewrite one repetitive paragraph of your own using all three devices.
In your next conversation, consciously use "I think so / I hope not" and one ellipsis ("I'd love to").

🌟 Encouragement for the Journey

Cohesion is a quiet craft — no one applauds a well-placed the latter or a graceful omission. Yet these are precisely the touches that make advanced English feel effortless to the person listening. You're no longer just choosing the right words; you're weaving them together. Keep pulling that thread — it's what turns fluency into style. 🧵
