Have you decided on your main topic for the project?

Not yet, but I’m thinking about a few different ideas.

Root Explanation

Subtopic → It is formed from "sub-" (meaning under or below) and "topic" (from Greek "topos", meaning place or subject). The word "subtopic" refers to a subject that is under or a subdivision of a main topic.

Memory Tip

Think of a topic that has something 'under' it — 'sub-' means under, and 'topic' refers to a subject. A subtopic is simply a subject that falls under a larger subject.
