Usage of complete inversion and partial inversion

1) Adverbs such as here, there, now, then are placed at the beginning of the sentence, and verbs such as be, come, go, lie and run are often used as predicate verbs. For example:

Then the bus came. This is your letter.

2) Place adverbs or adverbials indicating the direction of movement are placed at the beginning of the sentence, and the predicate indicates the movement verb.

A boy rushed out.

There is an old woman sitting in front.

But if the subject is a personal pronoun, it can't be reversed, for example, you are here. They're gone.

2. Partial inversion (incomplete inversion)

1) Words with negative or semi-negative sentences at the beginning, such as no, not, never, less, little, hardy, at no time, no way, not until … etc.

I have never seen such a performance.

The mother didn't leave the room until the child fell asleep.

When Not until leads the subject-predicate complex sentence, the main sentence is inverted and the clauses are not inverted. Note: If the negative word is not at the beginning of the sentence, it will not be inverted. I have never seen such a performance.

The mother didn't leave the room until the child fell asleep.

2) The beginning of negative words is inverted.

For example, not only … but also, it is difficult/rare … when, faster than …, and so on. For example:

Not only did he refuse the gift, but he also severely criticized the giver. He didn't accept the gift and severely criticized the giver.

Hardly had she gone out when a student came to see her. Hardly had she gone out when a student called.

Hardly had she gone out when a student camel came to visit her. Hardly had she gone out when a student came to visit her.

3) Therefore, it is neither inverted nor partially inverted.

Sentences that use these words to mean "yes" and "no" should be partially inverted. For example:

Tom can speak French. So can Jack. Tom can speak French, so can Jack.

If you don't go, I won't go without you.

4)only+ prepositional phrases/adverbs/adverbial clauses

Only in this way can you learn English well. Only in this way can you learn English well.

He didn't come to the meeting until he was asked three times. He didn't come to the meeting until he was called three times.

If the sentence is a compound sentence, the main clause is inverted and the clause is not inverted. For example:

Only when he is seriously ill does he stay in bed. He stays in bed only when he is seriously ill.

5) inverted sentences are guided by 5)as, though

As/though-guided concession clauses must advance predicative or adverbial (adjectives, adverbs, participles and notional verbs). But it should be noted that:

1) The noun at the beginning of a sentence cannot have any articles.

2) The first sentence is a notional verb, and other auxiliary verbs are placed after the subject. If a notional verb has an object and an adverbial, it is placed before the subject together with the notional verb. For example:

Hard as he works, he never seems to finish the work satisfactorily. He works hard, but he is never satisfied.

Note: in adverbial clauses, when there are through and when, the main clause behind it cannot have but, but through and yet can be used together.

6) Other parts are inverted.

1)) so … When the so in that sentence pattern is at the beginning of the sentence, it needs to be inverted. For example:

He was too scared to move a step. He was too scared to move.

2)) In some sentence patterns expressing wishes. For example:

May you all be happy. May you all be happy.

3) In the subjunctive conditional sentence, the predicate verbs of clauses include words such as was, had and should. If can be omitted, and were, had, should be moved to the front of the subject and partially inverted. For example:

If I were you, I would try again. If I were you, I would try again.

In fact, inverted sentences are easier to master, as long as you remember that some of them are complete inverted sentences and the rest are partial inverted sentences, which is what you said. I hope it helps you!
