What word order really asks you to do
Moving information to a different position so the same facts arrive in a different order — the technique for sentences whose words cannot be replaced.
What English lets you move, and what it does not
English is a fixed-order language in one specific way: the subject comes before its verb, and the verb before its object. Almost everything else can move. Time phrases, place phrases, whole conditional clauses and reported sources all slide to the front of a sentence, and the only thing they need on arrival is a comma. That single comma is most of what this technique asks you to remember.
What cannot move is the relationship between a modifier and the thing it modifies. “Only students pay the fee” and “Students only pay the fee” are two different claims, and nothing in the words themselves tells you which is which — position is carrying the meaning on its own. Spanish can afford to be looser here because it marks these relationships in other ways; English cannot, and a word that drifts takes its meaning with it.
The second thing that cannot move is the verb, upward past its subject. “In the last decade climbed the proportion of stressed children…” is a sentence a Spanish speaker writes without noticing anything wrong, because Spanish allows verb before subject freely. English allows it in a handful of fixed inversions and nowhere else, and this is one of the errors that most clearly marks a response as translated.
Free to moveTime phrases, place phrases, “if” clauses, “according to X”. Front them and add the comma.
Moves together or not at allA comparison has two sides. Flip “more” to “less” and both sides must swap with it, or the sentence claims the opposite.
Never movesA modifier away from its noun. “Only” is the classic case: its position is its meaning.
Never invertsSubject before verb. Fronting a phrase does not license “climbed the proportion”.
Why this is the technique that rescues you
Every prompt eventually hands you a sentence whose key words have no synonyms: a technical topic, a figure, a place name. A paraphrase built only on synonyms stalls there — and what usually happens next is that the writer replaces a technical term with something inaccurate rather than admit the sentence is stuck. Reordering has no such ceiling.
Moving one element forces the rest of the sentence to reorganise around it, which is why a single move can carry an entire paraphrase without touching one content word. It is also the technique that most often saves a rewrite which has started to look like the original with two adjectives changed.
What it costs you to skip this
Skipping it means running out of paraphrase on any prompt with technical vocabulary, and falling back on replacing terms that should not be replaced. Doing it wrong costs elsewhere: a fronted phrase without its comma reads as careless, and an inverted verb reads as a first-language error — and both of those land in Grammatical Range and Accuracy rather than in Lexical Resource, so the damage shows up on a criterion you were not even working on.
Where it stops applying
Reordering must not become rewriting. If the new version claims a cause the original did not, or drops an element to make the sentence flow better, it has stopped being a paraphrase of that prompt. The test is mechanical and worth running: every fact in the original should be findable in the new version, and no fact should have appeared that was not there before.
