Week 19 — Rhetorical devices, persuasive talks and sponsoring others

This week

Grammar: rhetorical devices (contrast, triads, rhetorical questions) · Vocabulary: rhetoric and persuasion (cogent, captivate, rebut, premise, sway) · Idioms & phrasal verbs: make the case, win over, get buy-in, strike a chord, drive home · Speaking: persuasive talks · Writing: blog post draft · Soft skill: sponsoring and advocating for others

Theme: structure is persuasion. Well-chosen contrast, a clean triad, or one good question makes a technical argument memorable; too many make you sound like a politician.

Day 1 — Grammar: rhetorical devices (contrast, triads, rhetorical questions)

⏱ 30 min · Mon

Rule in 60 seconds

Rhetorical devices are grammatical patterns that create emphasis. Each depends on parallelism (same grammatical form for parallel ideas).

• Contrast (antithesis): two parallel structures set against each other: "We are not building a faster horse; we are building a car." Patterns: not X but Y, X, whereas Y, less about X, more about Y, "Fast, but not at the expense of quality". Both halves must have the same form.
• Triads (tricolon): three parallel items, in ascending order of importance or length: "It reduces noise, prevents outages, and protects revenue." Three feels complete; two feels partial, four feels like a list. Items must be grammatically identical (all adjectives, all verb phrases).
• Anaphora: repeating the opening of successive clauses: "We need the data. We need the time. We need the mandate."
• Rhetorical question: a question asked for effect, answered by you, or left obvious. Use falling intonation on wh-questions. Best used to frame a problem before answering it: "What does an hour of downtime cost us? About two hundred thousand dollars."
• Emphatic inversion: Not only did we cut cost, but we also improved latency (inversion after negative adverbials, week 10 review).

Exceptions and cautions: one or two devices per minute of speech is plenty; more sounds theatrical. In writing, one triad per paragraph at most. Rhetorical questions are risky when the honest answer might be "nobody" or "not us".

The error fluent speakers make: non-parallel triads ("faster, cheaper, and it has better reliability") and missing inversion after "not only" ("Not only we cut cost..."). Also uneven contrasts: "slow to change and expensive maintaining" (second half needs to maintain).

Exercise

1. Name the device: "We didn't build it to impress; we built it to endure."
2. Fix parallelism: "The platform is faster, cheaper, and it has better reliability."
3. Order for ascending impact (justify your choice): reduces alert noise / prevents outages / protects revenue.
4. Correct: "Not only we reduced cost, but we also improved latency."
5. Turn into a rhetorical question plus answer: "Our incident response takes forty minutes, which is too slow."
6. Which question is risky in a presentation and why? (a) "What would it mean if we halved deploy time?" (b) "Who really cares about deploy time?"
7. Name the device: "We need the data. We need the time. We need the mandate."
8. Fix the contrast: "The old design was slow to change and expensive maintaining."
9. Rewrite with contrast: "We plan to release quickly and we want to keep quality high."
10. Which is over-rhetorical for a status update, and why? (a) "The migration is 70 percent complete." (b) "Are we ready? Not yet. Will we be ready? Yes. Will it be easy? No, it will be hard, worth it, and unforgettable."

Answers and explanations

1. Contrast (antithesis): X, not Y structure with parallel verb phrases.
2. "faster, cheaper, and more reliable." All three must be adjectives.
3. noise, then outages, then revenue (ascending business impact, ending on what the audience values most). This ordering is a judgment: the principle is to end with the item that matters most to your audience.
4. "Not only did we reduce cost, but we also improved latency." Inversion after a negative adverbial (not only).
5. Model: "How long does it take us to respond to an incident? Forty minutes. That is too long."
6. (b). It invites a cynical answer ("nobody"). (a) invites reflection and leads to your point.
7. Anaphora (repeated opening), also a triad.
8. "slow to change and expensive to maintain." Both adjectives need matching complements.
9. Model: "We will release quickly, without sacrificing quality" or "Fast, but not at the expense of quality."
10. (b). Stacks a question sequence, a triad and a contrast in one breath; status updates need facts, not oratory.

Use it

Write three sentences about a proposal you support: one contrast, one clean triad (parallel form) and one rhetorical question with the answer. Read them aloud with falling intonation on the answer.

Day 2 — Vocabulary: rhetoric and persuasion vocabulary (cogent, captivate, rebut, premise, sway)

⏱ 30 min · Tue

Word	Part of speech	Meaning	Example
cogent	adjective	Clear, logical and convincing	"Her cogent argument for a phased rollout persuaded the board."
captivate	verb	To hold someone's attention completely by being interesting, attractive or persuasive	"The story of the missed shipment captivated the executives far more than the throughput chart."
rebut	verb	To argue against or disprove a claim with evidence	"The postmortem rebuts the claim that the outage was caused by a single deploy."
premise	noun	A statement or assumption on which an argument is based	"The whole plan rests on the premise that traffic will double in a year."
sway	verb	To influence someone's opinion or decision	"Data from the pilot swayed the committee in our favor."

Collocations and word family

• cogent: a cogent argument / case / explanation / analysis; noun cogency. It describes arguments and explanations, rarely people; prefer "a cogent argument" to "a cogent speaker".
• captivate: captivate an audience / a room; adjective captivating; noun captivation (rare, prefer the adjective form). Do not confuse with capture (to gain, more neutral).
• rebut: rebut a claim / an argument / an accusation; noun rebuttal (offer / present a rebuttal). Not the same as refute (to prove wrong) or deny.
• premise: a false / flawed / sound premise; on the premise that; challenge the premise. Do not confuse with premises (a building), pronounced PREM-i-siz.
• sway: sway opinion / voters / a decision / the jury; be swayed by; hold sway (have influence).
• Pronunciation: CO-jent, CAP-ti-vate, re-BUT, PREM-is, SWAY.

Exercise

Cloze. Word bank: cogent, captivate, rebut, premise, sway, contingent, tenable, attest.

2. Only the data from two independent pilots could ______ the skeptics on the board.
3. To ______ the claim that the outage was our fault, we published the vendor's own logs.
4. His ______ summary of the trade-offs ended the debate.
5. Lead with the customer story; it will ______ the room better than the benchmark.
6. The recommendation is ______ on getting the budget approved by June.
7. A single-cloud approach is not ______ once regulators require data residency in three regions.
8. We should ______ to the vendor's figures with our own test before quoting them.

Answers and explanations

1. premise: the assumption underlying the plan.
2. sway: influence opinion.
3. rebut: argue against a claim.
4. cogent: clear and convincing.
5. captivate: hold the audience's attention.
6. contingent (week 12): dependent on.
7. tenable (week 16): defensible.
8. attest (week 15): provide clear evidence that something is true.

Use it

Say three sentences using premise, rebut and captivate about a real decision your team is debating.

Day 3 — Speaking: persuasive talks

⏱ 30 min · Wed

Prompt (60-90 seconds). Convince a skeptical architecture review board to adopt a shared logging standard across teams. Assume two members oppose any new standard.

Structure: C-R-E-C-C (Claim, Reason, Evidence, Counter, Call)

1. Claim: "We should adopt one logging standard, and we should do it this quarter."
2. Reason: why it matters to them, not to you.
3. Evidence: a number, a story or a pilot.
4. Counter: state and answer the strongest objection before they do ("The concern is migration cost; the pilot showed two days per service").
5. Call: a specific action and date.

Use one contrast, one triad and one rhetorical question, at most.

Pronunciation micro-drill: pitch patterns for rhetorical devices

• Triad intonation: rising, rising, falling: "faster (↗), cheaper (↗), and safer (↘)". Practise with: "It cuts noise, prevents outages, and protects revenue."
• Contrast stress: stress the contrasting words: "We're not asking for MORE time; we're asking for the RIGHT time."
• Rhetorical wh-question: falling tone, then a two-second pause before the answer: "What does an hour of downtime COST us? (pause) Two hundred thousand DOLlars."
• Slow down on the key number, and pause before it.

Self-check - [ ] I used exactly one contrast, one triad and one rhetorical question (not four). - [ ] The triad had rising-rising-falling intonation. - [ ] I paused before the key number and before the call to action. - [ ] I named and answered the strongest objection. - [ ] The call to action was specific (what and by when).

Day 4 — Idioms & phrasal verbs: persuasion idioms

⏱ 30 min · Thu

Expression	Meaning	Example
make the case (for)	To present arguments and evidence in support of something. Neutral to formal; very common in business.	"She made a compelling case for investing in observability."
win (someone) over	To persuade a doubtful person to support you. Phrasal verb; positive; separable: "win him over".	"The demo won over the skeptics in finance."
get buy-in	To get people's agreement and commitment to support a plan. Business jargon (US-origin, now universal).	"We need buy-in from security before we start."
strike a chord	To evoke a sympathetic response; to resonate with someone emotionally. Neutral; slightly literary.	"Her point about customer trust struck a chord with the board."
drive (something) home	To make a point clear and impossible to ignore, often by repetition. Neutral; separable: "drive the point home".	"The outage cost of two million dollars drove the point home."

Exercise (8 items)

1. Fill in: "I'd like to ______ for replacing the legacy scheduler."
2. Fill in: "It took three demos to ______ the skeptics."
3. Fill in: "Before we announce it, we need ______ from the operations leads."
4. Choose: "His story about a missed shipment ______ with the audience." (struck a chord / drove home)
5. Rewrite more idiomatically: "A single chart made the seriousness of the risk impossible to ignore."
6. Which form is correct: "win over him" or "win him over"?
7. Review (week 17): "He pushed for a target well beyond what was likely; that was a ______."
8. Which is more formal in a proposal: "make the case" or "get buy-in"?

Answers and explanations

1. make the case.
2. win over (or "win over the skeptics").
3. buy-in.
4. struck a chord. Drove home refers to emphasis, not emotional response.
5. "A single chart drove the point home."
6. "win him over." With a pronoun the object goes between verb and particle; with a noun both orders are possible ("win over the skeptics" or "win the skeptics over").
7. stretch goal (week 17).
8. "make the case": "get buy-in" is business jargon, best in speech and internal notes.

When NOT to use them: win over can sound manipulative if you describe your own tactics ("I'll win him over") in front of him. Buy-in is overused; in formal documents write "agreement" or "endorsement". Strike a chord is for genuine emotional response, not for data. Never use drive home about a serious incident in a way that sounds triumphant.

Day 5 — Writing: blog post draft

⏱ 30 min · Fri

Bad draft (introduction and first section of a technical blog post):

In this post I am going to talk about testing. Testing is important in software and there are many kinds of tests. We had some problems with our tests recently and they were slow and flaky and people did not trust them. So we did some work to improve them and I will explain what we did and what we learned.

Task. Rewrite it as the opening of the blog post (about 180-220 words), using: a hook that names a specific moment or number; one contrast; one triad (parallel form); one rhetorical question with its answer; and a clear promise of what the reader will learn. Keep one voice: direct and first-person plural.

Model answer

Last March, our main branch was red for eleven days, and nobody panicked. That was the problem.

When a test suite fails so often that nobody reacts, it has stopped being a safety net. It has become background noise. Our suite took 47 minutes, failed randomly one run in five, and taught engineers to click "retry" instead of "investigate".

So what do you do with a test suite nobody trusts? Most teams add more tests. We deleted a third of ours.

Over the next quarter, we did not chase coverage; we chased confidence. We quarantined flaky tests, split the suite by risk, and made every failure actionable. The result: a 9-minute pipeline, a flake rate below one in a hundred, and, more importantly, engineers who look at a red build and worry.

In this post I'll show the three changes that mattered most, the metrics we used to prove they worked, and one mistake that cost us two weeks.

What changed and why: - The hook is a concrete fact with tension ("red for eleven days, and nobody panicked"), instead of "testing is important". - Contrast: "did not chase coverage; we chased confidence" gives the post its thesis. - Triad: "quarantined... split... made..." (parallel verb phrases in ascending scope). - Rhetorical question ("what do you do with a test suite nobody trusts?") is answered at once, so it pulls the reader forward. - The promise at the end lists exactly what the reader will get; "what we did and what we learned" told them nothing.

Day 6 — Speaking record: a persuasive talk

⏱ 30 min · Sat

Record a 2-minute talk. Persuade your department to retire a beloved legacy tool (or, if you prefer, to adopt one process change). Assume the audience is fond of the old way.

Structure: hook (15 s) - claim (15 s) - reason and evidence (30 s) - counter to the strongest objection (30 s) - vision of the outcome (15 s) - call to action (15 s). Use at least one contrast, one triad and one rhetorical question, plus two of this week's words (cogent, captivate, rebut, premise, sway).

Scoring rubric (1 to 4)

Criterion	1	2	3	4
Clarity	Message unclear	Point emerges late	Clear main point	Point is unmistakable and memorable
Structure	No visible order	Some order, jumps	Clear sequence	Signposted, objection answered
Fluency	Frequent stops/fillers	Occasional long pauses	Mostly smooth	Smooth with deliberate pauses
Grammar accuracy	Errors block meaning	Frequent errors	Few errors	Parallelism and inversion accurate
Vocabulary range	Repeats basic words	Some C1 words	Good range	Precise, varied, natural
Pronunciation	Hard to follow	Stress errors distract	Generally clear	Pitch patterns support the devices

Shadowing task. Shadow two minutes of Simon Sinek's TED talk "How great leaders inspire action" or Julian Treasure's TED talk "How to speak so that people want to listen". Note where each speaker uses a contrast, a triad or a pause for effect, and copy it.

Log your score: total out of 24, plus the number of rhetorical devices you used (aim for three, not more).

Day 7 — Soft skills + weekly review: sponsoring and advocating for others

⏱ 30 min · Sun

Scenario. In a promotion calibration meeting, the committee is about to pass over Amara, a quiet senior engineer whose work on the routing engine prevented two major outages. A committee member says: "I don't hear her in meetings, so I'm not sure about her impact." You are in the room and know her work well.

Task. Write about 150 words of what you say. A sponsor speaks with their reputation on the line: name the evidence, connect it to the criteria and preempt the objection.

Model response

"I'd like to speak to that, because I think we may be measuring visibility rather than impact. Amara doesn't speak much in meetings; she writes. Her routing design document is the reason we avoided two major outages this year, and she convinced three teams to adopt it without a single escalation. That is influence without authority, exactly the senior criterion we've been discussing.

Concretely: the September failover, which would have cost roughly 1.5 million dollars, did not become an incident because of her circuit-breaker design. I'm prepared to put my name to that.

If we're concerned about visibility, that's a coaching point for her next year, and I'll take it on personally. But it shouldn't outweigh the evidence of her impact. I'd ask us to evaluate her on outcomes."

Techniques used: (1) Reframe the objection ("visibility rather than impact") instead of contradicting the person. (2) Specific evidence with a number. (3) Map to the promotion criteria language. (4) Take personal risk ("I'm prepared to put my name to that"), which distinguishes sponsorship from mentoring. (5) Offer a solution to the legitimate concern (coaching). (6) Close with a clear ask.
