Confoundingly → It is formed from "con-" (meaning together) and "found" (from Latin "fundere", meaning to pour or melt). The suffix "-ly" indicates the manner of the action. The word "confoundingly" means in a manner that causes confusion or perplexity, often by mixing things together in an unexpected way.
