Sense: noun/1
A crossword is a specific type of puzzle where you solve written clues and write the answers into a numbered grid. A word search also uses a grid of letters, but you simply find hidden words rather than solving clues — it requires less reasoning. Sudoku is a number-placement puzzle with no words or clues at all, only digits from 1 to 9. Brainteaser is the most general term and can refer to any short mental challenge, including riddles or logic problems, not necessarily involving a grid. So while all four test your thinking, only the crossword combines vocabulary knowledge with a crossing-letter grid structure. For example, a Sunday newspaper might include a crossword for vocabulary lovers, a sudoku for number fans, and a brainteaser for quick thinkers.

Etymology
The word 'crossword' is a blend of 'cross' and 'word', formed because the words in the puzzle cross each other — reading across (left to right) and down (top to bottom). The first modern crossword puzzle was created by British-born journalist Arthur Wynne and appeared in the New York World newspaper on December 21, 1913. The word itself was first recorded in English around 1924.
