What does perplexing mean?
Perplexing describes something that causes confusion, uncertainty, or difficulty of understanding. It may modify a question, puzzle, situation, or pattern of behavior, particularly when an explanation does not seem available. For example, a researcher might describe unexpected results as “perplexing” when the available evidence does not support an obvious conclusion. The word is somewhat more formal than “confusing” but less formal than “inexplicable,” which can suggest that something is wholly beyond explanation. Perplexing is also distinguished by its implication of sustained puzzlement rather than momentary difficulty. While the adjective focuses on something that causes bafflement, “perplexed” ordinarily describes the person experiencing that state. The word is useful in precise writing because it conveys not merely difficulty but an unresolved intellectual or interpretive challenge.

Where does perplexing come from?
Perplexing was formed in English in the early 17th century from Latin perplexus, meaning “entangled” or “confused.” That Latin word combines the intensive prefix per- with plexus, a term associated with being woven or intertwined. The related English words perplex and perplexity preserve the same ancestry and the original idea of mental entanglement.
