Word Origin for confound

C13: from Old French confondre, from Latin confundere to mingle, pour together, from fundere to pour

Word Origin and History for confound

c.1300, "make uneasy, abash," from Anglo-French confoundre, Old French confondre (12c.) "crush, ruin, disgrace, throw into disorder," from Latin confundere "to confuse," literally "to pour together, mix, mingle," from com- "together" (see com-) + fundere "to pour" (see found (v.2)).

The figurative sense of "confuse, fail to distinguish, mix up" emerged in Latin, passed into French and thence into Middle English, where it is mostly found in Scripture; the sense of "destroy utterly" is recorded in English from c.1300. Meaning "perplex" is late 14c. The Latin past participle confusus, meanwhile, became confused (q.v.).
