Perplex and Bewilder are two words that are often used interchangeably to describe a state of confusion or uncertainty. They both refer to a feeling of being unable to understand something or make sense of it. Perplex is derived from the Latin perplexus, meaning 'ENTANGLED' or 'INVOLVED, ' while Bewilder is derived from the Old English bewil(d)drian, meaning 'to lead astray.' Both words can be used to describe a situation in which someone is confused or uncertain about what to do or how to proceed.
