Advanced Word Order. Word order controls focus through inversion, fronting, clefts and end-weight.
The idea
After a fronted negative or restrictive adverbial, invert the subject and auxiliary. Use do when no auxiliary exists.
Structure & examples
Rarely have I heard such a thoughtful proposal.
Not until noon did the fog lift.
Notice the pattern
Inversion affects the main clause when a restrictive expression is placed first. If there is no auxiliary, introduce do, does or did and use a base verb. Not until introduces an unchanged subordinate clause, followed by an inverted main clause: Not until she called did I understand.
Never have I felt so welcome.
Only then did she understand.
Important notes & common mistakes
Invert the main clause, not the clause following not until.
Before you practice
First choose a form from the options. Then produce it yourself using the word or structure in the instruction. Finally, build complete sentences. Check the explanation after each answer and revisit any mistakes in your review list.
Extended topic: Advanced Word Order
Word order controls focus through inversion, fronting, clefts and end-weight. Negative fronting triggers auxiliary inversion; fronted objects normally do not. Heavy information often comes later. Only before an adverbial can trigger inversion, but only before the subject does not.
Examples in context
Notice how each form fits its sentence. Read the context before choosing a form.
Only after the vote did they reveal the cost.
