Root Explanation

**Screwworm** → The word is formed from "screw" (from Old English *scrūwan*, meaning to twist or turn) and "worm" (from Old English *wyrm*, meaning serpent or worm). The term describes a type of fly larva that burrows into the flesh, resembling a screw's twisting motion as it enters the body.

Memory Tip

Think of the word 'screw' which suggests a twisting action, and 'worm' which refers to a creature that burrows. This helps you remember that a screwworm is a larva that twists and burrows into flesh.
