Sentence Structure & Emphasis
Summary
- Beyond negative adverbials, inversion follows fronted 'so + adjective', 'such', and 'only + time/condition' phrases. The structure adds emphasis in formal English.
Structure

Examples
- So tired was she that she fell asleep at her desk.
- Such was the demand that tickets sold out in minutes.
- Only later did we realise our mistake.

Common mistakes
- • Forgetting the inversion: 'So tired she was' should be 'So tired was she'.
- • Inverting the wrong clause when 'only when' fronts a time clause; invert the main clause.

Basic Word Order
A1
English statements normally follow subject + verb + object order. Adverbs and time expressions go in fixed positions rather than between the verb and its object.
And, But, Or
A1
These conjunctions join words, phrases, or clauses. 'And' adds, 'but' contrasts, and 'or' offers a choice.
Inversion After Negative Adverbials
C2
When a negative or restrictive adverbial begins a sentence for emphasis, the subject and auxiliary invert as in a question. This is a formal, dramatic device.
Cleft Sentences
C1
Cleft sentences split one idea into two clauses to emphasise a particular element. 'It-clefts' begin with 'It is/was', and 'what-clefts' (pseudo-clefts) begin with a 'what'-clause.
Subjunctive / Were
C1
English keeps a small subjunctive. The present subjunctive uses the base verb after verbs of demand or suggestion, and the past subjunctive 'were' is used for all persons in unreal conditions.
Ellipsis and Substitution
C1
To avoid repetition, English omits words (ellipsis) or replaces them with shorter forms like 'so', 'do', 'one', and 'neither' (substitution). Both keep sentences economical and cohesive.
