Simple explanation
What is an idiomatic grammar pattern? An idiomatic grammar pattern is a fixed or semi-fixed grammatical structure whose meaning or use cannot be explained entirely by the ordinary meanings of its individual parts. In It's high time we left, for example, left is formally past tense, but the sentence refers to the present. The past form expresses distance and the idea that an action is already overdue. Why do these patterns matter at C2 level? At C2 level, grammatical accuracy alone is not enough. Advanced users need to express criticism, concession, preference, inevitability, uncertainty, and stance with precision. Idiomatic grammar patterns are important because they often encode these meanings more naturally and efficiently than literal or fully compositional alternatives. Fixed and semi-fixed structures Some patterns are highly fixed, such as Be that as it may and Come what may. Others contain variable slots, such as There's no + -ing or not so much X as Y. These structures are best learned as complete patterns rather than reconstructed word by word each time. When form and time do not match Some idiomatic patterns use tense forms for meanings other than time reference. In I'd rather you stayed, the past form stayed usually refers to a present or future preference. Likewise, It's high time we acted refers to present necessity rather than a past event. This use of past forms is often associated with distance, tentativeness, or unreality. Register is part of the grammar A structure can be grammatically correct but pragmatically inappropriate. Far be it from me to and Be that as it may sound formal or rhetorical, whereas you'd better and there's no telling are common in everyday speech. C2 competence therefore requires control over form, meaning, and register at the same time.

Core rules
- 1
It's high time + past simple
Use It's high time + subject + past simple to say that something should happen now and probably should have happened earlier. The past tense does not refer to past time here; it expresses distance and overdue necessity.
- 2
would rather + subject + past
When a preference concerns another person's present or future behavior, use would rather + subject + past simple: I'd rather you stayed. For a preference or regret about the past, use the past perfect: I'd rather you had told me earlier.
- 3
had better + base verb
Use had better for strong advice, especially when an undesirable consequence is implied. It is followed by the base form without to: You'd better leave now. The negative form is had better not + base verb.
- 4
Be that as it may
Use this fixed expression to acknowledge a previous point without allowing it to change the main argument. It is broadly equivalent to Even if that is true or Nevertheless, but it is more formal and rhetorical.
- 5
Far be it from me to + infinitive
This relatively formal structure is used to distance the speaker from a judgment, criticism, or interference, often immediately before expressing exactly that kind of judgment. The inverted be it form is fixed.
- 6
Come what may
Come what may means whatever happens and emphasizes that a decision, commitment, or situation will remain unchanged regardless of future events. The word order is fixed.
- 7
If need be
If need be means if necessary. It is a compact fixed expression and is particularly natural in formal or carefully structured speech and writing.
- 8
not so much X as Y
Use not so much X as Y to correct or refine an interpretation. It means that something is less accurately described as X and more accurately described as Y. The two elements should normally be structurally parallel.
- 9
what with X and Y
Use what with to introduce multiple causes that jointly explain a result, often an inconvenient or difficult one. It can be followed by nouns, noun phrases, or -ing forms.
- 10
there's no + -ing
Use there is no + gerund to express impossibility, unpredictability, or the absence of a realistic way to perform an action. Common combinations include there's no telling, there's no knowing, there's no denying, and there's no escaping.
- 11
have yet to + base verb
Use have yet to to say that something has not happened up to the present point, while implying that it is still expected or possible. It is especially common in formal, academic, and journalistic English.
- 12
cannot help but + base verb
Use cannot help but + base verb to describe a reaction or conclusion that feels almost unavoidable. A related structure is can't help + -ing, but after cannot help but the verb stays in the base form.
Useful examples
It's high time we reconsidered the assumptions behind the policy.
We really need to reconsider the assumptions behind the policy now, and perhaps should have done so earlier.
The past form reconsidered expresses overdue necessity rather than past time.
I'd rather you didn't draw any conclusions until we've seen the full report.
I would prefer you not to reach any conclusions before we have seen the complete report.
The past form follows would rather because the preference concerns another person's present or future behavior.
I'd rather they had raised the issue before the contract was signed.
I wish they had raised the issue before the contract was signed.
The past perfect marks a preference about a past situation that can no longer be changed.
You'd better not make that claim unless you can substantiate it.
It would be wise not to make that claim unless you can support it with evidence.
Had better expresses strong advice and often implies consequences.
Be that as it may, we still need to account for the discrepancy.
Even if that point is accepted, we still need to explain the discrepancy.
The phrase concedes a point without abandoning the speaker's main argument.
Far be it from me to tell you how to run your department, but the current arrangement seems unsustainable.
I do not wish to interfere in how you run your department, but the current arrangement appears unsustainable.
The speaker distances themselves from criticism before making a critical observation.
Come what may, the data will remain publicly available.
Whatever happens, the data will continue to be publicly available.
The expression emphasizes that the commitment will not change.
We can postpone the launch by a week, if need be.
We can delay the launch by one week if that becomes necessary.
If need be is a compact fixed alternative to if necessary.
Her response was not so much defensive as genuinely puzzled.
Her response was better described as genuinely puzzled than as defensive.
The second description replaces the first with a more accurate interpretation.
What with the train cancellations and the roads being flooded, hardly anyone made it to the meeting.
Because of both the train cancellations and the flooded roads, almost nobody reached the meeting.
What with presents several contributing causes together.
There's no telling how the market will react to the announcement.
It is impossible to predict how the market will react to the announcement.
There's no telling is a highly established pattern for unpredictability.
There is no denying that the proposal has considerable merit.
It is impossible to deny that the proposal has significant strengths.
There's no denying is often used to acknowledge a point strongly.
The investigators have yet to determine what caused the failure.
The investigators still have not determined the cause of the failure.
Have yet to highlights something that remains undone up to the present.
One cannot help but wonder whether the omission was deliberate.
It is difficult not to wonder whether the omission was intentional.
Cannot help but often sounds formal or argumentative.
The distinction may seem trivial, but it is anything but irrelevant.
The distinction may appear trivial, but it is certainly not irrelevant.
Anything but + adjective means the opposite of that adjective, often emphatically.
Common mistakes
- ❌ It's high time we leave. ✅ It's high time we left. The standard idiomatic pattern uses the past simple after It's high time even when the meaning is present.
- ❌ I'd rather you don't tell anyone. ✅ I'd rather you didn't tell anyone. A present or future preference about another person's behavior normally takes the past simple after would rather.
- ❌ You had better to check the figures again. ✅ You had better check the figures again. Had better is followed by the base form without to.
- ❌ You'd better don't mention it. ✅ You'd better not mention it. The negative pattern is had better not + base verb.
- ❌ There is no to know what happened. ✅ There is no knowing what happened. The idiomatic pattern there is no + verb requires an -ing form.
- ❌ The committee has yet reached a conclusion. ✅ The committee has yet to reach a conclusion. The correct structure is have or has yet to + base verb.
- ❌ Far be it for me to criticize her. ✅ Far be it from me to criticize her. The fixed expression requires the preposition from.
- ❌ It was not so much confusing than misleading. ✅ It was not so much confusing as misleading. The fixed pattern is not so much X as Y, not not so much X than Y.
- ❌ I cannot help but wondering whether he knew. ✅ I cannot help but wonder whether he knew. After cannot help but, use the base form. The alternative I can't help wondering is also correct.
- ❌ What with to miss the bus and the rain, we were late. ✅ What with missing the bus and the rain, we were late. After what with, use a noun, noun phrase, or -ing form rather than a to-infinitive.
Learning tips
- Learn idiomatic grammar patterns as complete chunks rather than rebuilding them from individual words.
- Record three things for each pattern: its grammatical form, its pragmatic meaning, and its register.
- Remember that a past form does not always indicate past time; in patterns such as It's high time and I'd rather you stayed, it expresses distance or unreality.
- Do not treat had better as a direct synonym of should; had better normally sounds stronger and often implies consequences.
- Keep X and Y grammatically parallel in not so much X as Y whenever possible.
- Use highly formal expressions such as Far be it from me to selectively; overuse can make ordinary conversation sound artificial.
- Learn common lexical combinations inside productive patterns, such as there's no denying, there's no telling, and have yet to determine.
- At C2 level, complexity is useful only when it improves precision, stance, or register. Do not add advanced patterns merely to make a sentence look sophisticated.

Frequently asked questions
Are idiomatic grammar patterns the same as idioms?
Not exactly. An idiom is usually a lexical expression with a meaning that cannot be predicted directly from its words, such as spill the beans. An idiomatic grammar pattern also involves a characteristic syntactic structure, often with variable elements, such as I'd rather you + past simple.
Why do we use the past after It's high time if we are talking about the present?
The past form does not function as ordinary past time here. English can use past forms to express distance, unreality, or evaluation. With It's high time, it signals that an action is now necessary and often already overdue.
What is the difference between I'd rather you stayed and I'd rather you had stayed?
I'd rather you stayed normally refers to a present or future preference. I'd rather you had stayed refers to the past and expresses a preference or regret about a situation that can no longer be changed.
Is had better the same as should?
No. Both can express advice, but had better usually sounds stronger and more urgent. It often suggests that an undesirable consequence may follow if the advice is ignored.
Does Be that as it may sound natural in everyday conversation?
It is grammatically correct, but it sounds relatively formal, argumentative, or rhetorical. In casual conversation, alternatives such as even so, still, or that may be true are often more natural.
Can any verb be used after There's no in the -ing form?
The pattern is partly productive, but not every combination is equally idiomatic. Established expressions such as there's no telling, there's no knowing, there's no denying, and there's no escaping are especially natural.
What is the difference between can't help doing and can't help but do?
Both can express an unavoidable reaction. Can't help + -ing is very common across registers, while cannot help but + base verb often appears in more formal or argumentative contexts.
How can I tell whether an advanced pattern sounds too formal?
Learn register together with grammar. Expressions such as Far be it from me to and Be that as it may are noticeably formal, whereas you'd better and there's no telling are common in ordinary speech. Correctness alone does not guarantee contextual appropriateness.
