Crosswords, or crossword puzzles, first appeared in the US in the early 20th century. Today, many people in the US and in Britain regularly do crosswords, sometimes on the bus or train on their way to work. Most newspapers and magazines contain at least one crossword and there are often prizes for people who send in the correct solution. Books of crosswords are also popular.
Solving a crossword involves answering a set of clues. The answers are words or phrases which fit together in a patterned grid. The clues are usually numbered and listed as across and down, according to whether the answer reads across the grid or from top to bottom.
There are two basic types of crossword, called in Britain quick crosswords and cryptic crosswords. In quick crosswords the clues are usually definitions of the answers. This is much the most common type of crossword in the US, where the grids are usually a lot bigger and contain many more words. These crosswords are not necessarily easy, and the one in the Sunday issue of the ↑New York Times is considered very difficult.
Cryptic crosswords, which began in Britain and are much more popular there than in any other country, have clues which contain both a definition of the answer and a word puzzle involving the letters in it. One common type of word puzzle is an anagram, in which the letters of the answer word are rearranged in the clue to form another word or phrase. For example, CARTHORSE and SHORT RACE are both anagrams of the word ORCHESTRA.
