Information Packaging and Rhetorical Structure (C1 Grammar)

Information packaging refers to how writers and speakers organize information within sentences to control emphasis, focus, and flow. Advanced structures like cleft sentences, fronting, extraposition, and inversion allow you to highlight key information, create dramatic effect, and maintain cohesion in academic and professional discourse.

Quick tip: It-cleft = focus one element. What-cleft = build to the focus. Extraposition = move heavy subjects to the end. Fronted negation = dramatic emphasis with inversion.

It-Clefts (Focusing on Specific Elements)

Use 'It is/was + focused element + that/who' to highlight a specific piece of information. The focused element receives maximum emphasis.

• It was the methodology that ultimately determined the outcome. (focus on methodology)
• It is the lack of funding that prevents further research. (focus on the cause)
• It was Dr. Marchetti who first proposed this theoretical framework. (focus on the person)

What-Clefts (Pseudo-Clefts)

Use 'What + clause + is/was' to introduce known information before revealing the focus. Creates a building-up effect common in academic argumentation.

• What the evidence suggests is that early intervention is critical.
• What distinguishes this approach is its emphasis on qualitative data.
• What remains unclear is the long-term impact of these policies.

Extraposition

Move a heavy subject clause to the end and replace it with 'it' at the beginning. Makes sentences easier to process and is standard in academic writing.

• It has been demonstrated that regular exercise improves cognitive function. (extraposed 'that' clause)
• It is essential to consider all variables before drawing conclusions. (extraposed 'to' infinitive)
• It remains to be seen whether these results can be replicated. (extraposed 'whether' clause)

Fronted Negative Inversion

Place a negative or restrictive expression at the beginning of the sentence and invert the subject-verb order. Creates formal emphasis and dramatic effect.

• Not only did the study confirm the hypothesis, but it also revealed unexpected patterns.
• Under no circumstances should participants be exposed to unnecessary risk.
• Rarely has a single study generated such widespread debate.

Impersonal Passives

Use impersonal passive constructions to present information objectively, distancing the writer from the claim. Common in reporting research findings.

• It is widely acknowledged that climate change poses significant risks.
• The results are believed to support the original hypothesis.
• These findings have been interpreted as evidence of systemic bias.

Common mistakes

• Not "What the study found was is that the treatment worked." — say "What the study found was that the treatment worked.". Do not double the verb in what-clefts. 'What...found was that' is the correct pattern, not 'was is that'..
• Not "Not only the study confirmed the hypothesis, but it also revealed new data." — say "Not only did the study confirm the hypothesis, but it also revealed new data.". After fronted negative expressions ('not only', 'rarely', 'under no circumstances'), subject-verb inversion is required: 'did the study confirm', not 'the study confirmed'..

Practise it

Read academic journal abstracts and identify information packaging strategies. Notice how authors use clefts to highlight key findings, extraposition to manage heavy subjects, and fronted negation for emphasis. Practice rewriting the same sentence using different packaging structures.
