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.

Complex Sentence: Contains one independent clause and at least one dependent subordinate clause. Example: Although he was ill, he attended the lecture.
