Root Explanation
Thumbnail → It is formed from "thumb" (from Old English "þuma", meaning the short, thick digit) and "nail" (from Old English "nægel", meaning a hard covering). The word "thumbnail" refers to a small image or representation that is as small as a thumb's nail.
Memory Tip
Think of a small image that is about the size of your 'thumb' — that's why it's called a thumbnail.
