simple (English)
Where does "simple" come from?
The word 'simple' traces its origin back to the Latin 'simplex,' a compound meaning 'onefold' that combined the roots for 'one' and 'to fold.' Inherited through Old French and Middle English, the term originally carried the literal sense of being uncompounded or made of a single element. Over time, this evolved from its technical use in botany and theology to describe anything straightforward, plain, or uncomplicated.
