Advanced Grammar: C1–C2

An advanced grammar and style reference for inversion, information structure, clefting, nominalisation, advanced modality, ellipsis, discourse grammar and stylistic choice.

1. Inversion

Negative and restrictive fronting

After fronted negative/restrictive expressions, auxiliary-subject inversion is common: Rarely have I seen…, Only later did we realise…, Under no circumstances should you….

Transform: “We understood the scale only after the audit.”
Answer

Only after the audit did we understand the scale.

2. Cleft sentences

It-clefts and wh-clefts

It was the timing that caused the problem. / What caused the problem was the timing. Clefts redistribute information focus.

3. Fronting and marked word order

Stylistic emphasis

More concerning was the lack of evidence. Marked order can create contrast, textual cohesion or rhetorical emphasis.

4. Nominalisation

Density and abstraction

The team failed to respond quickly → The team's failure to respond promptly…. Useful in formal writing, but excessive nominalisation obscures agency and inflates prose.

5. Ellipsis and substitution

Avoiding repetition

I think so. / Neither did I. / If necessary… / Those who do…. Ellipsis relies on recoverable context.

6. Advanced modality

Commitment and epistemic stance

Compare must, should, is likely to, may, might, cannot be ruled out. These forms encode different degrees of speaker commitment.

7. Counterfactual and remote structures

Were to, had + inversion, should

Were the situation to change…, Had I known…, Should you require assistance…. These are formal alternatives to standard if-clauses.

8. Advanced participle clauses

Perfect and passive participles

Having been informed of the delay, the committee postponed the vote. Ensure the implied subject is controlled.

9. Complex noun phrases

Pre- and post-modification

Dense noun phrases can package information: a recently published cross-national survey of workplace communication practices. Use carefully to avoid processing overload.

10. Discourse grammar

Theme, rheme and reference

Writers manage old/new information, topic continuity and reference with forms such as this finding, such an approach, the former, the latter.

11. Hedging and boosting

Calibrating claims

Hedges: appears to, may, arguably, tends to. Boosters: clearly, strongly, demonstrates. Effective advanced writing calibrates rather than simply weakens or strengthens.

12. Pragmatic grammar

Politeness, distance and interpersonal meaning

I was wondering if… uses past forms for social distance, not literal past time. You wouldn't happen to know…? softens a request through modal remoteness.

13. Advanced relative structures

Preposition + relative, sentential which

The framework within which the policy operates…; The decision was postponed, which surprised everyone.

14. Style-sensitive grammar

Formal, neutral and conversational choices

Advanced grammar is not automatically better. Choose structures according to genre, audience and effect.
