Need more help? Make an appointment with the MSU Writing Center. Their tutors meet individually or in groups with undergraduate student writers of all abilities and backgrounds at any stage in their writing processes -- from invention to revision.
A topic is the main organizing principle of a discussion, either verbal or written. Topics offer us an occasion for speaking or writing and a focus which governs what we say. They are the subject matter of our conversations, and the avenues by which we arrive at other subjects of conversations. Consider, for instance, a recent class discussion. Although your instructor determined what topic you discussed initially, some students probably asked questions that led to other topics. As the subjects of our discussions lead to related subjects, so do the topics we write about lead to related topics in our academic studies.
