Week 14 — Negotiation and calibrated certainty¶

This week

Grammar: degrees of certainty (modals and adverbs) · Vocabulary: concession, deadlock, reciprocate, predicated, entrenched · Idioms & phrasal verbs: hold out, give in, back down, dig in, come around · Speaking: handling pushback live · Writing: writing a proposal · Soft skill: negotiation practice

Theme: in a negotiation, every sentence carries a confidence level. Say "will" when you mean "should" and you lose credibility; say "might" when you mean "will" and you lose leverage.

Day 1 — Grammar: degrees of certainty, modals and adverbs¶

⏱ 30 min · Mon

Rule in 60 seconds¶

English lets you dial certainty up and down with modal verbs and adverbs. Learn the ladder, then match it to your real confidence.

Certainty	Modals	Adverbs / phrases
~100%	will, must (deduction only), can't (negative deduction)	definitely, certainly, undoubtedly, is bound to
~75-90%	should, ought to	probably, is (very) likely to, presumably
~30-60%	may, might, could	possibly, perhaps, maybe, conceivably
~10-25%	might (not), could (just)	is unlikely to, hardly likely, is a long shot

Rules and exceptions

Deduction (present): must be (I'm sure it is), can't be (I'm sure it isn't). Past deduction: must have + past participle, can't have + past participle. Never mustn't for deduction; mustn't means prohibition.
Prediction: use will, should, is likely to. Must is not used to predict the future. Should here means "I expect", not obligation: "The load test should finish by five."
Possibility: may / might / could. Could = possible; can't = impossible. Plain can is not used for a single specific possibility ("The cause can be DNS" sounds off; use "could be").
Continuing action: modal + be + -ing: "The vendor may be stalling."
Past possibility: modal + have + past participle: "It might have been the cache."
Adverb position: before the main verb but after the first auxiliary or modal: "We will probably miss the date." With a negative, probably/definitely go before the contracted negative: "We probably won't make it", "We definitely didn't agree to that." Also correct and slightly more formal: "We will probably not make it."
Maybe vs may be: maybe is an adverb ("Maybe they'll accept"); may be is modal + verb ("They may be willing").
Register note (US vs UK): likely alone as an adverb ("It will likely fail") is common in US business English; British usage prefers probably or very likely. Both are acceptable in a US company; the safest form everywhere is is likely to.

The error fluent speakers make: double hedging and mixed signals. "It will probably maybe be the cache" or "It is unlikely that it will probably be…" stacks two uncertainty markers and sounds evasive. Choose one. The other frequent error: using must for a future expectation ("The report must be ready by Friday" sounds like an order, not a forecast).

Exercise¶

Correct the error: "The failover mustn't have worked, because the replica is still serving stale data."
Choose the best option: "Traffic patterns suggest the outage (can / could) have been caused by the DNS change."
Correct the error: "We will not probably meet the deadline."
Choose the best option: "The load test ends at four, so the results (should / must) be ready by five."
Transform, keeping the meaning (one sentence, modal + perfect): "I'm certain they didn't read the RFC."
Choose: "(Maybe / May be) the vendor will accept a phased rollout."
Correct the error: "Hmm, the logs are quiet. The service may be restart."
Rank from most to least certain: (a) "It might slip." (b) "It is bound to slip." © "It is likely to slip."
Calibrate this overconfident claim, given you only tested in staging: "This change will cut latency by 40 percent."
Correct the double hedge: "It is unlikely that the cache will be probably the cause."

Answers and explanations

"The failover can't have worked." Negative deduction about the past uses can't have, not mustn't have. Mustn't never expresses deduction.
could. Could have expresses one specific past possibility. Can have is not used affirmatively in this sense.
"We will probably not meet the deadline" or "We probably won't meet the deadline." Probably sits before not/n't when the negative follows the modal; "will not probably" is not idiomatic.
should. This is an expectation about the future, not a deduction about something already true. Must would sound like an instruction.
"They can't have read the RFC." (couldn't have read is also correct.) Certainty about a past negative equals can't have + past participle.
Maybe. It is a sentence adverb meaning "perhaps"; may be needs a following adjective or verb phrase ("may be willing").
"The service may be restarting." Continuing action = modal + be + -ing.
(b) > © > (a). Is bound to is near certainty, is likely to is probable, might is merely possible.
Model: "This should reduce latency noticeably; in staging we saw roughly 40 percent, but production traffic is more varied." Any answer that (1) downgrades will to should/is likely to and (2) states the evidence and its limit is correct.
"It is unlikely that the cache is the cause." Unlikely already carries the hedge; adding probably doubles it. Note the present tense: the cause is a present fact, not a future event.

Use it¶

Write three sentences about a current project: one at about 90 percent certainty (should / is likely to), one at 50 percent (might / could), and one deduction about a past event (must have / can't have). Say them aloud twice.

Day 2 — Vocabulary: negotiation vocabulary (concession, deadlock, reciprocate, predicated, entrenched)¶

⏱ 30 min · Tue

Word	Part of speech	Meaning	Example
concession	noun	Something you agree to give up or allow in order to reach agreement	"We offered a concession on payment terms in return for a two-year commitment."
deadlock	noun / verb	A situation in which no progress is possible because each side refuses to move	"Talks over the SLA penalty reached deadlock, so we escalated to the steering committee."
reciprocate	verb	To respond to a gesture or favor with a similar one	"We extended the trial period, and we expect the vendor to reciprocate with a volume discount."
predicated	adjective (past participle)	Based on or dependent on something being true or happening (used as `predicated on/upon`)	"The go-live date is predicated on the security review closing by the 15^th."
entrenched	adjective	Firmly established and hard to change, said of positions, habits or interests	"Both teams had entrenched positions on who should own the routing service."

Collocations and word family¶

concession: make / offer / grant / win a concession; a major / minor / token concession; concessions on price / scope / timeline. Verb: concede (a point). A token concession is small and symbolic.
deadlock: break / end / resolve a deadlock; reach / hit a deadlock; deadlock over / between. Close synonym: impasse (more formal). As a verb, "the negotiations deadlocked."
reciprocate: reciprocate a gesture / an offer / a favor. Related: reciprocal (adjective: a reciprocal agreement), reciprocity (noun).
predicated: predicated on / upon (never "predicated from"); from the verb predicate (to base a claim or action on something); do not confuse with the adjective contingent (dependent on an uncertain future event), which is a close but distinct near-synonym.
entrenched: entrenched positions / interests / habits / attitudes. Verb: entrench; noun: entrenchment. Not to be confused with trench.
Pronunciation: con-CES-sion, DEAD-lock, re-CIP-ro-cate, PRED-i-cate-d, en-TRENCHED.

Exercise¶

Cloze. Word bank (each word used once): concession, deadlock, reciprocate, predicated, entrenched, leverage, rationale, mandate.

The procurement team has no ______ to sign contracts above two million dollars; that needs the CFO.
When a supplier makes a ______ on lead time, you should acknowledge it explicitly.
The offer is ______ on legal signing off on the data-residency clause.
After three rounds with no movement, we were in ______ and needed a neutral facilitator.
Your best ______ in this renewal is that we can credibly move workloads to another cloud within a quarter.
Explain your ______ before you state your number; people accept a figure they understand.
Years of "we've always done it this way" have left the release process deeply ______.
If we grant the extension, they should ______ by waiving the change-request fee.

Answers and explanations

mandate: formal authority to act (a review word from week 13).
concession: something given up.
predicated: the offer is based on / depends on a condition being met, taking on.
deadlock: no progress possible; "in deadlock" is a fixed pattern.
leverage: bargaining power (review from week 10).
rationale: the reasoning behind a decision (review from week 7).
entrenched: habits become firmly established.
reciprocate: respond in kind.

Use it¶

Say three sentences about a real vendor or internal negotiation, using predicated on, make a concession and deadlock. Record yourself if you can and check that the stress falls on the right syllable.

Day 3 — Speaking: handling pushback live¶

⏱ 30 min · Wed

Prompt (60-90 seconds). A senior product manager says in a meeting: "Freezing scope two weeks early is unrealistic. Sales has already promised two features to the customer." Respond out loud as the engineering lead. You want to keep the freeze but you need the relationship.

Structure: A-A-A-C (Acknowledge, Anchor, Alternative, Check)

Acknowledge the concern without agreeing: "I understand the commitment to the customer puts you in a hard spot."
Anchor in a fact or shared goal: "The risk is that two late features push regression testing past the release window, which would put the whole date at risk."
Alternative: offer an option, ideally two: "I can take feature A inside the freeze if we drop the report export, or we can ship both in a follow-up release on the 28^th."
Check: "Would either of those work for the customer commitment?"

Useful frames: "I hear you, and..." (avoid "but", which cancels the acknowledgment); "What I can offer is..."; "The trade-off is..."; "Help me understand what is fixed and what is flexible."

Pronunciation micro-drill: stress in noun/verb pairs and negotiation terms

Noun stress on the first syllable, verb stress on the second:

Noun	Verb
CON-flict	con-FLICT
PRO-test	pro-TEST
PRO-ject	pro-JECT
RE-cord	re-CORD
IN-crease	in-CREASE
CON-tract	con-TRACT (to shrink)

Say each pair, then a sentence: "We had a CON-flict over scope." / "The two schedules con-FLICT." Stress carries the meaning in negotiation: "We can do the DATE or the SCOPE, not both" (contrast stress).

Linking with phrasal verbs (consonant plus vowel): give_in, back_down, hold_out, come_around. Say them as one flowing unit: "gi-vin", "hol-dout".

Self-check - [ ] I acknowledged before I disagreed, and did not use "but" straight after "I understand". - [ ] I offered at least one alternative, not only a refusal. - [ ] I ended with a question, and my voice went up or stayed level, not trailing off. - [ ] I stressed the noun/verb pairs correctly (CON-flict / con-FLICT). - [ ] I kept it under 90 seconds without rushing.

Day 4 — Idioms & phrasal verbs: hold out, give in, back down (negotiation)¶

⏱ 30 min · Thu

Expression	Meaning	Example
hold out (for)	To refuse to accept less than you want, often waiting for a better offer. Neutral; "hold out for" takes the thing you want.	"The vendor is holding out for a three-year commitment."
give in (to)	To stop resisting and accept something you resisted. Slightly negative: suggests defeat. Neutral alternative: "concede".	"We gave in on the deadline but kept the scope."
back down	To withdraw a demand or position because of pressure. Can sound like losing face; informal-neutral.	"Neither side wanted to back down over the SLA wording."
dig in (your heels)	To refuse firmly to change your position, often stubbornly. Informal; usually critical when said about others.	"Once legal dug in their heels, the contract stalled for weeks."
come around (to)	To be persuaded and change your opinion. Informal; positive tone.	"Finance came around to the phased rollout after we showed the cost curve."

Exercise (8 items)¶

Fill each gap with the correct form of one of the five expressions.

After two weeks of pressure, the vendor finally ______ on the price increase.
Don't ______ too early; they usually improve the offer at the last minute.
The architecture board ______ their heels and would not approve the exception.
I think the CTO will ______ to the idea once she sees the failure-rate data.
Rewrite more idiomatically: "We refused to accept the first offer and waited for a better one."
Rewrite more idiomatically: "The regional team eventually accepted the change even though they did not want to."
Choose the most diplomatic to say to a client: (a) "You need to back down." (b) "Is there any flexibility on this point?" © "Stop digging in."
Which expression describes a change of mind through persuasion rather than pressure: give in, back down, or come around?

Answers and explanations

backed down (withdrew the demand under pressure). Gave in is also plausible if the vendor accepted the buyer's terms; here "backed down on the price increase" is the collocation.
give in (accept too soon).
dug in (past of "dig in").
come around (be persuaded).
"We held out for a better offer."
"The regional team eventually gave in." (or "came around" if they were persuaded, not forced).
(b). It invites movement without labeling the other side as stubborn; (a) and © are confrontational.
come around. Give in and back down imply pressure; come around implies persuasion.

When NOT to use them: give in, back down and dig in carry judgment about someone's behavior; do not say them to the person you are negotiating with ("You are digging in"). Use neutral phrasing ("I sense we're both holding firm on this") or describe the interest ("It sounds like the deadline is fixed for you"). In written contracts and formal proposals use "concede", "withdraw", "maintain a position".

Day 5 — Writing: writing a proposal¶

⏱ 30 min · Fri

Bad draft (an email to a director):

Hi, I wanted to talk about the booking service. It's old and has a lot of issues and the team spends much time fixing things. I think we should probably think about maybe replacing it with something better. It would take some months I guess and cost some money. Let me know what you think, we can discuss.

Task. Rewrite as a proposal of 150-200 words with these constraints: - open with the recommendation (one sentence); - state the problem with at least one number (invent plausible ones); - give two options considered and why you recommend one; - state the cost and timeline as ranges, with one condition using "predicated on"; - end with a specific decision request and date; - calibrated certainty: no "maybe / I guess / probably" stacking.

Model answer

Subject: Proposal: replace the legacy booking service by Q2 (decision needed by 10 October)

I recommend we replace the legacy booking service with a modular service built on our current platform, delivered in two phases by end of Q2.

Problem. The current service accounts for 38 percent of production incidents and consumes roughly six engineer-weeks per quarter in manual fixes. Its release cycle is monthly because changes cannot be tested in isolation.

Options considered. 1. Keep and patch: lowest upfront cost, but the incident trend is unlikely to improve, and we already miss our availability target twice a quarter. 2. Replace in two phases (recommended): higher upfront cost, but it removes the highest-risk components first and lets us retire the old code incrementally.

Cost and timeline. Six to eight engineers for two quarters, roughly 400-500k dollars. The Q2 date is predicated on the payments API freeze being lifted in November.

Decision requested. Please approve Phase 1 funding by 10 October so we can start hiring contractors this month.

What changed and why: - The recommendation moved to the first sentence (BLUF), so the reader knows the ask immediately. - "Something better", "some months", "some money" became concrete figures and ranges; vague quantities read as unprepared. - "probably think about maybe" (three hedges) became a direct recommendation; uncertainty is expressed once, in the timeline condition. - Options are listed with a reason for the choice, which signals you weighed alternatives (essential for buy-in). - "Let me know what you think" became a dated decision request.

Day 6 — Speaking record: handling a live negotiation pitch¶

⏱ 30 min · Sat

Record a 2-minute talk. You are asking the Head of Operations to accept a phased cutover of the new routing engine (region by region over six weeks) instead of a single weekend cutover. She prefers the weekend cutover because it is simpler. Persuade her, and respond to one imagined objection out loud ("Six weeks means running two systems").

Structure: state your recommendation (10 s) - her interest and yours (20 s) - the trade-off in one number (20 s) - concession you can offer (20 s) - pre-empt the biggest objection (30 s) - the ask and a next step (20 s).

Scoring rubric (1 to 4; score yourself after listening once, then again after a day)

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 and easy to follow
Fluency	Frequent stops/fillers	Occasional long pauses	Mostly smooth	Smooth with deliberate pauses
Grammar accuracy	Errors block meaning	Frequent errors	Few errors, no confusion	Rare errors; certainty modals used precisely
Vocabulary range	Repeats basic words	Some C1 words	Good range, some negotiation terms	Precise, varied, natural
Pronunciation	Hard to follow	Stress errors distract	Generally clear	Clear stress and rhythm

Shadowing task. Choose a two-minute segment of a TED or TEDx talk about negotiation or persuasion (search ted.com for "negotiation"), or a BBC 6 Minute English episode on the same theme. Play a sentence, pause, and repeat it with the same rhythm and stress; then shadow (speak simultaneously, half a beat behind) for the whole segment. Check any word you stumble on on YouGlish (youglish.com) or Forvo.

Log your score: total out of 24 and your lowest criterion. Write it in your log under Week 14.

Day 7 — Soft skills + weekly review: negotiation practice¶

⏱ 30 min · Sun

Scenario. Your cloud vendor's renewal quote is 30 percent higher than last year. Their account executive says it "reflects market conditions" and the offer expires Friday. Your VP wants the increase under 10 percent. You have credible evidence that migrating one workload to another provider is feasible within a quarter, but you do not want to reveal that yet. You have a meeting tomorrow.

Task. Write a 150-word script or email that (1) states your position, (2) makes a conditional concession, (3) uses at least two certainty markers accurately, and (4) leaves the door open. Do not threaten.

Model response

"Thank you for the quote and for walking us through the rationale. We value the partnership and want to renew. However, a 30 percent increase is well outside what we can justify internally; we're looking at a figure closer to a 10 percent uplift.

We can be flexible on commitment length. If you can bring the increase to that range, we would be willing to consider a three-year term, which gives you more certainty than a one-year renewal. This is predicated on pricing for the additional storage tier being included.

We understand your Friday deadline, but a decision of this size needs proper review, so I would ask for an extension to the 15^th. It is unlikely we will decide before then. Could we set up a call on Thursday to explore what is possible?"

Techniques used: (1) Acknowledge first, then state the position ("We value the partnership... However"). (2) An anchor number given as a range ("closer to"), which keeps room to move. (3) The concession is conditional and reciprocal: a longer term in exchange for a lower rate. (4) Certainty calibrated: "we would be willing to" (not "we will"), "It is unlikely we will decide" (honest, not a threat). (5) Deadline reframed as a process issue, not a refusal. (6) Ends with a specific next step. (7) The alternative provider is not revealed; leverage is preserved silently.
