Me: For the synonym of concise, you choose small.

Student: Yeah. Someone who is concise is direct; they don't use a lot of words. They use a small amount of words.

Me: Yes. You wouldn't call a concise person small, right? A small person could be verbose.

Student: You're small and to the point.

Me: True.
