Root Explanation

Turtleback is formed from "turtle" (from Middle English *turtel*, meaning a type of reptile) and "back" (from Old English *bæc*, meaning the rear part of something). The word describes the back of a turtle, which is often domed and resembles a shell.

Memory Tip

Think of the word 'turtle' describing a reptile with a distinctive shell on its 'back' — that's why 'turtleback' refers to the shape of a turtle's back.
