The term 'Source of Confusion' can be described by two crossword solutions: MAZE (4 letters) and PUZZLE (6 letters). A MAZE is a complex network of paths or passages in which it is difficult to find one's way. It is often used as a game or recreational activity, where the goal is to find a path from the start to the end. A PUZZLE is a problem or enigma that tests the ingenuity of the solver. Puzzles are often created to be a form of entertainment, but they can also have an educational purpose.
