Sense: adjective/1
"Confused" (A2) is the broadest and most common term for not being able to think clearly or understand something. "Puzzled" (B1) is milder — it suggests a specific problem or question you cannot figure out, like a crossword clue or a riddle. "Bewildered" (B2) adds a sense of surprise or shock, as if the situation is so strange that you cannot make sense of it at all. "Perplexed" (B2–C1) is more formal and suggests you have thought hard about something and still cannot understand it. "Disoriented" (B2) specifically means you have lost your sense of time, place, or direction, not just your understanding of an idea. For example: "I was puzzled by the last question on the test" (mild, specific); "The tourists looked bewildered when the guide spoke in a language they did not know" (surprise at the strangeness); "The professor was perplexed by the results of the experiment" (deep, thoughtful confusion).

Etymology
"Confused" comes from the Latin word "confusus", the past participle of "confundere", which means "to pour together" — like mixing different liquids into one container so they become hard to separate. "Con-" means "together" and "fundere" means "to pour". The word passed through French into English in the 1300s, first with the literal meaning of mixing or mingling things together, and later taking on the figurative sense of mixing up ideas or thoughts.
