Haha I like that idea, but it's your own personal definition. "-fold" is multiplicative and it's used to flexibly change the part of speech since at least Old E

Haha I like that idea, but it's your own personal definition. "-fold" is multiplicative and it's used to flexibly change the part of speech since at least Old English [1]. You can think of folds as referring to the individual layers of something folded, rather than the action of folding. It can be either depending on context. I can make 64 folds (layers) by making 6 folds (actions). [1] https://www.etymonline.com/word/-fold https://www.etymonline.com/word/-fold
