simple (English)
Where does "simple" come from?
The word 'simple' traces its origins back to the Proto-Indo-European roots for 'one' and 'fold,' which combined in Latin to form 'simplex,' literally meaning 'onefold.' This Latin term passed through Old French and Middle English, eventually displacing the native English word 'onefold.' Over time, its meaning expanded from a physical lack of complexity to include ideas of ease, innocence, and even social or mental modesty.
