Inversion

Inversion occurs when we change the normal word order of a sentence, typically placing the auxiliary verb before the subject. It's used for emphasis, in formal writing, and in certain grammatical constructions.

Types of Inversion

1. After Negative Adverbials

When sentences begin with negative adverbials, we invert the subject and auxiliary verb.

Never, rarely, seldom, hardly

Never have I seen such a beautiful sunset.
Rarely does she complain about anything.
Seldom do we get such good weather.
Hardly had we arrived when it started raining.

No sooner... than

No sooner had I sat down than the phone rang.
No sooner did we leave than it started snowing.

Not only... but also

Not only did he arrive late, but he also forgot his presentation.
Not only is she intelligent, but she is also very kind.

At no time, under no circumstances

At no time did we consider giving up.
Under no circumstances should you open that door.

2. After "Only" Expressions

When sentences begin with "only" + adverbial phrase, inversion is required.

Only then, only when, only if

Only then did I realize my mistake.
Only when I saw the results did I understand the problem.
Only if you study hard will you pass the exam.

Only by, only through, only with

Only by working together can we solve this problem.
Only through practice will you improve your skills.
Only with your help could we complete the project.

3. After "So" and "Neither/Nor"

Used to show agreement or similarity.

So + auxiliary + subject (positive agreement)

"I'm tired." → "So am I."
"She has finished." → "So have we."
"They will come." → "So will John."

Neither/Nor + auxiliary + subject (negative agreement)

"I don't like coffee." → "Neither do I."
"She hasn't arrived." → "Nor have they."
"We won't be there." → "Neither will Tom."

4. After "Little" and "Few"

When sentences begin with "little" or "few" meaning "not much/many":

Little did he know that his life was about to change.
Few people realize how difficult the situation really is.

5. In Conditional Sentences

We can omit "if" and invert the subject and auxiliary in formal conditionals.

Had (past perfect)

Had I known about the meeting, I would have attended.
Had they arrived earlier, they wouldn't have missed the show.

Were (subjunctive)

Were I you, I would accept the offer.
Were she here, she would help us.

Should (future possibility)

Should you need any help, please contact me.
Should the weather improve, we'll go hiking.

6. After Expressions of Place

In literary or formal writing, inversion occurs after expressions of place when the verb is intransitive.

In the corner stood an old grandfather clock.
On the table lay several important documents.
At the top of the hill sits a small church.

7. After "Here" and "There"

With verbs of movement or existence:

Here comes the bus.
There goes our last chance.
Here lies the problem.

Note: No inversion with pronouns:

Here it comes. (not "Here comes it")

8. After "Such"

When "such" begins a sentence for emphasis:

Such was his anger that he couldn't speak.
Such is life - unpredictable and challenging.

9. In Exclamations with "How" and "What"

How beautiful she looks in that dress!
What a wonderful day it is!

Question Tags with Inversion

After positive statements with inversion, use negative tags:

Rarely does he complain, does he?
Never have I seen such a thing, have I?
