1. Concession as a scale, not a switch
Many C2 learners treat concession as a switch: either you acknowledge the opponent’s objection or you do not. In reality, academic and professional English treats concession as a graded scale—from the smallest acknowledgment to a complete, unqualified one—and choosing the level is itself a rhetorical decision, not decoration added to a fixed structure.
The scale runs approximately as follows: minimal acknowledgment ("there is a degree of truth in X", "X is not without merit") → complete acknowledgment without reservations ("X is entirely correct", "the critics are right that..."). None of these levels is “safer” or “more polite” than the others—each establishes its own relationship between the concession and the counterclaim that follows.
The level you choose is not decoration on an unchanging argument structure but part of the argument itself: readers assess the weight of the author’s final position largely by how honestly the author was initially willing to concede.
Partial acknowledgment: to some extent / partly · Complete acknowledgment of a specific claim: fully / entirely · Concession marker: admittedly / granted / to be sure
There is, admittedly, some truth in the claim that the survey sample was small.
There is, admittedly, some truth in the claim that the survey sample was small.
Partial level: admittedly and some truth together acknowledge only partial validity, nothing more.
The reviewers are, in fact, entirely justified in their concern about the missing control group.
The reviewers are, in fact, entirely justified in their concern about the missing control group.
Complete level: entirely justified acknowledges the objection without any reservation, leaving room only for the counterargument that follows.
The proposal has, to a degree, underestimated the running costs.
The proposal has, to a degree, underestimated the running costs.
To a degree is a partial marker: it acknowledges validity without specifying how substantial it is.
2. Vocabulary for partial concession
To some extent, partly, and a degree of truth directly limit the degree of agreement. Admittedly, granted, and to be sure primarily introduce a concession: they can acknowledge a specific fact completely. Distinguish the degree of agreement from the scope of the claim—you can fully acknowledge one shortcoming without accepting all of the opponent’s conclusions.
A grammatical detail: most of these expressions are disjuncts (they appear between commas within a sentence) or fixed expressions. Not without merit is litotes (a double negative): it asserts that merit exists without stating how substantial it is.
A partial level is not the same as an absence of concession. If an author chooses partial vocabulary for an objection that is actually well supported, that is a calibration problem (Section 6), not a problem with the vocabulary itself.
Granted, the pilot ran in only one location.
Granted, the pilot ran in only one location.
Granted introduces an acknowledgment of fact: the pilot really did have one location. The partiality concerns the role of this fact in the wider argument, not the meaning of granted.
The argument is not without merit, though it rests on a single case study.
The argument is not without merit, though it rests on a single case study.
Not without merit is a typical partial level through litotes: it acknowledges the existence of merit without stating its degree.
To some extent, the delay was foreseeable.
To some extent, the delay was foreseeable.
To some extent limits the acknowledgment to a particular, though unspecified, degree, without moving to full acceptance of the opponent’s claim.
3. Vocabulary for complete concession
Complete markers—entirely correct, undoubtedly right, wholly justified, fully accept that, there is no question that X is right—acknowledge the objection without any reservation.
The most common grammatical trap here concerns word form: before a predicative adjective (correct, right, justified), you need an adverb, not an adjective: entirely, not entire; wholly, not whole; undoubtedly, not undoubted. The adjective form simply has nothing to modify in this position.
The complete level is especially typical of the C2 register—in reviews and formal responses to criticism—because when a fact is genuinely supported, complete honesty about one narrow detail does not harm the rest of the argument; instead, it strengthens confidence in it (Section 4).
The committee is undoubtedly right that the timeline was unrealistic.
The committee is undoubtedly right that the timeline was unrealistic.
Undoubtedly right is a complete level without reservations; the certainty of the acknowledgment leaves the opponent nothing to dispute on this particular point.
I fully accept that the first draft understated the risks.
I fully accept that the first draft understated the risks.
Fully accept that is a first-person performative verb of acknowledgment, a complete level without mitigating adverbs.
There is no question that the earlier estimate was too optimistic.
There is no question that the earlier estimate was too optimistic.
There is no question that denies the possibility of doubt itself—an idiomatic way to express the complete level.
4. The paradox of persuasiveness
Readers assess their confidence in an author largely by how honestly the author deals with opposing views. Fully acknowledging a well-known weakness signals confidence: the author is not afraid to acknowledge it because the real argument remains intact despite it.
By contrast, an author who always offers only a minimal concession to well-documented, serious objections appears evasive; an author who calibrates a complete concession to genuinely strong objections and keeps partial concession for weak ones earns more trust in the counterargument that follows—regardless of the level.
This paradox does not mean “always concede as much as possible”; it means matching the level to the real weight of the objection (Section 6), so that the size of the concession itself conveys information rather than being arbitrary.
The critics are entirely correct that implementation was flawed; the underlying policy, however, remains sound.
The critics are entirely correct that implementation was flawed; the underlying policy, however, remains sound.
A complete concession about implementation makes the following “however” more persuasive because the author does not conceal the weak point.
Admittedly, the interview count is low, but the pattern it reveals matches three independent surveys.
Admittedly, the interview count is low, but the pattern it reveals matches three independent surveys.
Admittedly acknowledges the fact that the number of interviews is low. The second part explains why this shortcoming does not invalidate the entire conclusion; the marker does not mean that the fact itself is only partially true.
The department is right, without qualification, that costs rose faster than projected; the programme's outcomes justify the spending regardless.
The department is right, without qualification, that costs rose faster than projected; the programme's outcomes justify the spending regardless.
Without qualification strengthens the completeness of the concession to the same level as undoubtedly and prepares the ground for a strong regardless counterargument.
5. Two opposite calibration failures
Categorically rejecting all objections may seem inflexible if some of them are well founded. But concession is not required for the sake of politeness: an unfounded objection can be rejected directly, with an explanation of why.
A concession is excessive for the planned counterargument when, without sufficient grounds, it covers the entire claim. At the same time, fully accepting persuasive criticism is not a logical error: sometimes the evidence requires you to abandon your position rather than save it at any cost.
Check exactly what you are acknowledging and whether the evidence supports it. If the concession undermines your own conclusion, either narrow it to a justified scope or honestly revise the conclusion. The existence of a counterargument is not, by itself, a criterion of correctness.
Check the degree of agreement + the scope of the claim + the evidence; full acknowledgment of a narrow point ≠ acceptance of all conclusions
I cannot accept those objections, because each relies on the same incorrect date.
I cannot accept those objections, because each relies on the same incorrect date.
Rejecting all the objections mentioned may be justified; here, the speaker directly states the reason.
The reviewer is completely right that the whole design is flawed, and there is nothing more to add.
The reviewer is completely right that the whole design is flawed, and there is nothing more to add.
The speaker fully accepts the criticism and offers no counterargument. This is not self-refutation; its appropriateness depends on whether the evidence genuinely confirms that the entire design is flawed.
Granted, one section of the report is weak; the remaining analysis, however, still supports the recommendation.
Granted, one section of the report is weak; the remaining analysis, however, still supports the recommendation.
The weakness of one section is fully acknowledged, but the scope of the concession is limited. Granted by itself does not set the degree of agreement.
6. Calibrating the level to the weight of the objection
Match the degree of agreement to the evidence, and the scope to the precisely formulated claim. A minor but proven shortcoming can be fully acknowledged; the seriousness of the consequences and confidence in the fact are different questions.
Rhetorical risk arises when the words do not match the evidence or conceal the scope of the concession. There is no rule that an important observation always requires complete acknowledgment and an unimportant one partial acknowledgment: first determine how accurate it is.
A practical check: before choosing a marker, state the real weight of the objection in one phrase (“one anecdote”, “a replicated result”), and only then choose the level that matches that weight, rather than the one that seems safest to write.
Given that three independent audits reached the same conclusion, the auditors are undoubtedly correct that the reporting process needs revision.
Given that three independent audits reached the same conclusion, the auditors are undoubtedly correct that the reporting process needs revision.
Three independent audits are strong evidence, so the complete level undoubtedly correct matches its real weight.
Based on a single unverified comment, there is perhaps a degree of truth in the claim that turnout was affected.
Based on a single unverified comment, there is perhaps a degree of truth in the claim that turnout was affected.
One unverified piece of evidence is weak, so the partial level a degree of truth matches its weight, rather than the level undoubtedly.
The finding is undoubtedly accurate, but it is a minor point in the wider argument.
The finding is undoubtedly accurate, but it is a minor point in the wider argument.
Accuracy and importance are different scales. Undoubtedly accurate and minor point can be combined without contradiction.
7. Transfer: increasing the level in a paragraph and in conversation
At paragraph level, experienced authors often build several concessions of increasing strength before the strongest counterclaim, so that the reader experiences the argument’s honesty as a gradual progression rather than a one-time statement.
In live conversation (a panel discussion, a meeting), the same escalation can occur across turns: the speaker begins with a partial acknowledgment, and if presented with stronger evidence, raises the level in the next turn—the decision is revised in real time rather than fixed in advance.
Transfer check: can the author or speaker explain, for each step in the sequence, why the level increased precisely there rather than earlier or later? If the increase is not connected to the appearance of new evidence or a stronger objection, the sequence is decorative rather than reasoned.
The initial results are, to be sure, preliminary; closer inspection, however, shows the effect holding across every subgroup we tested.
The initial results are, to be sure, preliminary; closer inspection, however, shows the effect holding across every subgroup we tested.
To be sure acknowledges the preliminary status of the results, while however introduces an argument supporting them. This is a change in the role of the statements, not a fixed level of meaning for to be sure.
Once the second dataset confirmed the pattern, we had to move from there may be something in this to the original critics were entirely right.
Once the second dataset confirmed the pattern, we had to move from there may be something in this to the original critics were entirely right.
The increase in level is directly motivated by new evidence (the second dataset), not by a rhetorical habit of raising the tone.
In the meeting, she first granted that the rollout schedule was tight; when the client cited the missed deadline, she went further and agreed the schedule had, in fact, been unrealistic from the start.
In the meeting, she first granted that the rollout schedule was tight; when the client cited the missed deadline, she went further and agreed the schedule had, in fact, been unrealistic from the start.
The spoken escalation of the level occurs in response to the client’s specific new evidence (the missed deadline), not spontaneously.
Common mistakes
Incorrect:The reviewers are entire correct that the methodology has weaknesses.
Correct:The reviewers are entirely correct that the methodology has weaknesses.
Before the predicative adjective correct, you need the adverb entirely, not the adjective entire; the complete concession level always takes the adverbial form.
Incorrect:The committee's objection is whole justified, though the timeline was unrealistic.
Correct:The committee's objection is wholly justified, though the timeline was unrealistic.
Wholly is the adverb required before the predicative adjective justified; whole is only an adjective or noun and cannot perform this role.
Incorrect:There is some validity this criticism, but it overlooks the wider context.
Correct:There is some validity to this criticism, but it overlooks the wider context.
The partial expression validity to X requires the preposition to; without it, the noun phrase lacks the required complement.
Incorrect:The panel entirely correct on this point, yet the broader claim fails.
Correct:The panel is entirely correct on this point, yet the broader claim fails.
Before the adjective correct, you need the finite verb is. Entirely specifies the degree of correctness, but it does not replace the predicate.
Incorrect:What the critics fail to recognise, however, that the underlying principle remains sound.
Correct:What the critics fail to recognise, however, is that the underlying principle remains sound.
The pseudo-cleft construction What X fail to recognise ... is that ... requires the linking verb is; without it, the sentence lacks a main predicate.
Incorrect:The plan works to a degree, it is flawed in its funding model.
Correct:The plan works to a degree; however, it is flawed in its funding model.
In formal writing, do not join these independent clauses with a comma alone. You can use a semicolon with however, a period and However, or a comma with the coordinating conjunction but. However is a conjunctive adverb; it does not become a conjunction on its own.
