Root Explanation

Sigmoidoscope → It is formed from "sigmoid" (from Greek "sigmoides", meaning resembling the letter 'S') and "scope" (from Greek "skopein", meaning to look or examine). The word refers to an instrument used to look at the sigmoid colon, which is shaped like an 'S'.

Memory Tip

Imagine looking at the 'S'-shaped part of the colon with a tool that helps you 'examine' — that's what a sigmoidoscope does.
