Etymology

confound = con<together> + found<pour>

  • con (Latin con-, meaning "together" or "completely")
  • found (Latin fundere, meaning "to pour"; evolved into Old French confondre, meaning "to mix or confuse")

Etymology Origin:
The word confound traces back to Latin confundere ("to mix together, confuse"), combining con- (intensifying prefix) and fundere ("to pour"). The original sense was literal—pouring liquids together to create a mixture—but it later evolved metaphorically to mean "to confuse" or "to overwhelm." By the 14th century, it entered English via Old French, retaining its dual meaning of physical mixing and mental bewilderment. The archaic sense of "to defeat" reflects the idea of overwhelming an opponent.
