Transformation of sentences in english grammar refers to the systematic process of changing the grammatical structure or syntactic form of a sentence without altering its core propositional meaning. In HNDE examinations, General English assessments, and teaching exams across Sri Lanka, sentence transformation is frequently tested to assess a candidate’s mastery of English syntactic flexibility.

Key Transformation Types with Rules
A. Simple, Compound, and Complex Transformations
- Simple Sentence: Contains one independent clause with a single finite verb. Example: Inspite of his illness, he attended the lecture.
- Compound Sentence: Contains two independent clauses joined by a coordinating conjunction (FANBOYS). Example: He was ill, but he attended the lecture.
- Complex Sentence: Contains one independent clause and at least one dependent subordinate clause. Example: Although he was ill, he attended the lecture.
| Original Sentence Structure | Target Structure | Transformed Sentence | Connecting Rule |
|---|---|---|---|
| Too + adjective + to + verb | Complex (So... that... cannot) | The paper was so difficult that he could not pass it. | Negative consequence clause |
| As soon as + past tense | Negative inversion (No sooner had...) | No sooner had the bell rung than the students entered. | Time sequence correlation |
| Active: Someone stole the documents. | Passive Voice | The documents were stolen. | Agent omitted for formal tone |
| Assertive: Everybody loves liberty. | Rhetorical Question | Who does not love liberty? | Emphatic assertion |
| Standard: The lecturer inspired me. | Cleft Sentence (It-cleft) | It was the lecturer who inspired me. | Focus on subject noun phrase |
