Confoundedly → It is formed from "con-" (meaning together) and "found" (from Latin "fundare", meaning to establish or lay the foundation). The suffix "-edly" indicates manner. The word "confoundedly" means in a manner that is perplexing or confusing, often implying frustration or annoyance.
Think of 'together' ('con-') and 'establishing' ('found') something that is perplexing — that's why confoundedly means doing something in a confusing manner.
