The word origins from Anglo-French (1300) confoundre meaning “to destroy utterly”, and from Latin confundere meaning “to confuse, jumble together, bring into disorder”. It comes from com meaning “together” plus fundere meaning “to pour”. The figurative sense of “confuse the mind, perplex” emerged in Latin.
