Plural of fold: bends or creases in a material, or the action of bending something over itself.
From Old English 'faldan' meaning 'to fold or bend.' The word is related to Germanic languages and has remained largely unchanged for over a thousand years because the concept is so fundamental.
Origami—the Japanese art of paper folding—demonstrates something fascinating about folds: they're not just creases, but they're actually the most efficient way to create three-dimensional complexity from a flat surface, which is why engineers study origami patterns to design better solar panels and space equipment.
