I feel like some of our late-night study sessions are just gainless.

I get that, sometimes it feels like we aren't making any progress.

Yeah, we should probably find a better way to focus.

Definitely! Maybe we could set some specific goals for each session.

Root Explanation
Gainless → It is formed from "gain" (from Old English *gānian*, meaning to obtain or acquire) and "-less" (meaning without). The word "gainless" means without gain or profit.
Memory Tip
Think of being 'without' ('-less') something you could 'obtain' ('gain') — that's why gainless means having no profit.
