Perplexity is confusion that results from something being complicated. The instruction manuals for computer components might put a look of perplexity on your face. If you think of the word complexity — which is when something is really intricate or involves lots of complicated parts — it might help you remember that perplexity is the state that results from complexity. You might experience perplexity at the complexity of the plays your coach has diagrammed, or perplexity at the complicated menu options at an Indian restaurant.
