Scrapbook → It is formed from "scrap" (from Middle English *scrappe*, meaning a small piece or fragment) and "book" (from Old English *bōc*, meaning a written work or collection of pages). A scrapbook is a book made up of small pieces or fragments, often used for collecting memories or mementos.
Think of a 'small piece' ('scrap') collected in a 'written work' ('book') — that’s why a scrapbook is a book of collected pieces.
