Placing a negative adverbial at the start of a sentence creates dramatic emphasis and sounds formal or literary. It requires subject-auxiliary inversion — the same word order used in questions. These structures are common in formal speeches, essays, and literary writing.
Not sure which level to practice?Take the free level testWhen a negative or limiting adverbial moves to the front of a sentence for emphasis, the subject and the auxiliary swap places, exactly as they do in a question.
So the order is adverbial, then auxiliary, then subject, then the rest of the verb (Never have I felt so unprepared; Seldom does he admit being wrong). If the verb has no auxiliary of its own, do, does or did steps in and the main verb goes back to its base form (Rarely do we see such dedication), though be inverts on its own (Never was he so happy). Several of these openers come in fixed pairs — hardly or scarcely with when, no sooner with than, and not only with but also — and the hardly and no sooner patterns take the past perfect in the first half (No sooner had we sat down than the food arrived).
Invert the subject and the auxiliary after a fronted negative adverbial
Never have I seen such a talented team.
Add the auxiliary do when the verb has none of its own, so does and did appear in its place
Seldom does he work on weekends.
Use not only at the front to add a bigger second point, with but also in the next clause
Not only did she meet the deadline, but she also came in under budget.
Use hardly or scarcely with when for two events in quick succession
Hardly had I sat down when the phone rang.
Use no sooner with than, never with when
No sooner had they signed the contract than the company announced layoffs.
Save these openers for formal writing and speeches, where the effect is dramatic rather than everyday
Under no circumstances should you leave the building unattended.
