Usage simple terms · simple act · simple idea


Inherited from Middle English symple, simple, from Old French simple, from Latin simplex (“simple”, literally “onefold”) (as opposed to duplex (“double”, literally “twofold”)), from semel (“the same”) + plicō (“I fold”). See same and fold. Compare single, singular, simultaneous, etc. Partially displaced native English onefold.
