What does topic mean?
A topic is the subject, issue, or central idea under discussion. People use it to identify what a conversation, debate, lesson, article, or presentation is concerned with: for example, a speaker may announce the topic of a lecture or ask a group to remain on topic. In everyday English, topic is flexible and generally neutral, although “hot topic” suggests that the subject is especially current or controversial. In academic and instructional settings, it can also refer more broadly to a field or subject area, as in “a research topic” or “the topic of a course.” The related word “theme” often focuses on a particular, recurring idea expressed within a work, whereas “topic” emphasizes the subject matter being addressed. Topic is therefore useful whenever a writer or speaker needs to state clearly what is being discussed or examined.

Where does topic come from?
English adopted topic in the early 16th century from Greek topikos, meaning “of or relating to place,” through the Latin topics. Its ultimate source is the Greek topos, meaning “place,” a root preserved in words such as topical, topology, and topographical. In English, topic developed from its older rhetorical sense toward the modern meaning of the subject matter of discussion.
