Root Explanation

Cholesterol → It is formed from "chole-" (from Greek "chole", meaning bile) and "stereos" (meaning solid or firm). The word cholesterol refers to a solid substance found in bile, which is important for digestion and cellular function.

Memory Tip

Think of 'bile' ('chole') being a 'solid' ('stereos') substance — that's why cholesterol is related to a solid component found in bile.
