Inversion in English
Inversion reverses the normal subject-verb order for emphasis, formality, or after certain negative and restrictive expressions. It is a hallmark of advanced written and formal spoken English.
What is inversion?
Inversion places the auxiliary verb before the subject, reversing standard English word order. It is used after negative and restrictive adverbs placed at the start of a sentence.
Inversion after negative adverbs
| Expression | Standard order | Inverted |
|---|---|---|
| Never | I have never seen such skill. | Never have I seen such skill. |
| Rarely / seldom | She rarely misses a deadline. | Rarely does she miss a deadline. |
| Hardly / scarcely | I had hardly sat down when… | Hardly had I sat down when… |
| No sooner | He had no sooner arrived than… | No sooner had he arrived than… |
| Not only | She not only won but broke the record. | Not only did she win, but she also broke the record. |
| Only then / only after / only when | He realised only then. | Only then did he realise. |
| Under no circumstances | You should never open that door. | Under no circumstances should you open that door. |
| At no time / in no way / on no account | — | At no time was the public informed. |
Inversion with 'so' and 'neither/nor'
She loves jazz. So do I. (= I love jazz too.)
He can't swim. Neither can she. (= She can't swim either.)
They were late. So was I.
Inversion in conditionals (formal)
Were I in your position, I would accept. (= If I were in your position…)
Had she known, she would have acted differently. (= If she had known…)
Should you require assistance, please contact us. (= If you should require…)
Tip: Inversion always requires an auxiliary verb. If there isn't one in the original sentence, insert the correct form of do/does/did: 'Rarely does she miss a meeting.'
