In Lecture 5, students learned about conjunctions as joining words like and, but, or, so, because, which connect ideas, sentences, or choices. They also studied transitional devices such as first, next, then, finally, also, however, therefore, for example, which help sentences and paragraphs flow smoothly. Through examples and exercises, students practiced how conjunctions show relationships like addition, contrast, reason, and result, while transitional devices organize ideas clearly. The lecture also included a creative writing activity where students described an incident of kindness, helping them apply grammar and writing skills in real-life contexts.
