The solution to the problem was onefold, making it easy to understand.
Onefold → It is formed from "one" (from Old English "ān", meaning single or one) and "-fold" (from Old English "fald", meaning to fold or to double). The word "onefold" means having one layer or being single in form.
Think of 'one' as being single and 'fold' as a layer — so 'onefold' means having just one layer.
