About Key Word Transformations
Key word transformation is the sentence-level grammar test that scares most learners — and rewards them the most. You rewrite a sentence so it means the same, using a given key word and between two and five words in total.
What it tests
Each item gives a complete sentence, a key word, and a second sentence with a gap. You complete the second sentence with 2–5 words including the key word (unchanged), keeping the original meaning.
How it appears on the exam paper
The key word may never be changed, and answers outside the 2–5 word window score nothing even when grammatically perfect. Conditionals, reported speech, passives, modals and comparisons dominate this task.
Exam-style tips
- Never change the key word — not its tense, not its form.
- Count your words: contractions count as two words.
- Translate the meaning in your head before you write; the answer must mean the same, not just sound similar.
- Expect a trap in the 'easy' half of the sentence — re-read both sentences fully.
