S3 English Language: Adverb Particles On and Off

These notes by Phoebe Mbaziira of Trinity College Nabbingo explain how on and off combine with verbs to express different meanings. Examples cover attachment, mechanical operation, clothing, continuation, separation, reduction and conclusion. Suggested verb substitutions show how related expressions can be formed, while contrasting examples illustrate some differences between the two particles. A 20-item assignment asks learners to replace selected expressions with a simple verb followed by on or off. The material supports grammar practice and vocabulary development through explanations and sentence rewriting.
