Root Explanation

Sealing → It is formed from "seal" (from Old English *seolh*, meaning a device for making an impression) and "-ing" (a suffix used to form nouns indicating an action or process). The word "sealing" refers to the action or process of making something secure or closed, often with a seal.

Memory Tip

Think of using a 'seal' to make something secure, and the '-ing' shows that it's the action of doing that.
