Oh really? What did you see?

Root Explanation
Observation → It is formed from "ob-" (meaning against or toward) and "servare" (meaning to watch or keep). The word "observation" refers to the act of watching or monitoring something closely, often for the purpose of gathering information.
Memory Tip
Think of 'watching closely' ('servare') something 'toward' you ('ob-') — that's what observation means.
