A clue may contain two definition elements instead of having a definition part and a word game part. So exploring the cryptic crossword solution was relatively rare. Several discrete areas have been studied: cognitive or linguistic challenges arising from cryptic indications. the mechanisms by which the "Aha!" -Moment is triggered by the resolution of encrypted crosswords;  the use of cryptic crossword puzzles to maintain cognitive flexibility ("use-it-or-lose-it") in aging populations; and expert studies on high performance drivers and the ability to solve cryptography.    Ximenean`s rules are very precise in terms of grammar and syntax, particularly with regard to the indicators used for different wordplay methods. Libertarian setters can use devices that convey "more or less" the message. For example, if the BEER response of the Setters may decide to divide the word into BEE and R and, after finding appropriate ways to define the answer and BEE, now tries the Solver a reference to the letter R. Ximenean rules would not allow something like "to reach first" suggests that R is the first letter of "Reach" , because, grammatical, this is not what "Reach first" implies. Instead, a "first to reach" phrase would be needed, as this is consistent with the rules of grammar. However, many libertarian crossword writers would accept "Reach First," believing that it would be reasonable to convey the idea in a reasonable way. For example, a mention under the Ximene rules for BEER (BEE- R) may look like this: The answer is THE DARING, which means "difficult," and is preferred without its average letter, or "heartless." This type of index is common in British and Canadian crypts, but is somewhat less common in American crypts; in American crossword puzzles, an index like this is generally considered a punny clue. This is almost certainly the oldest type of cryptic index: cryptic definitions appeared in the enigmas of British newspapers in the late 1920s and early 1930s, which mixed cryptic and clear terms and became completely cryptic crossword puzzles.
In Britain, it is traditionally – dated to the cryptic crossword pioneer Edward (Bill) Powys Mathers (1892-1939) which, according to the Spanish inquisitator, was called torquemada – for the compiler to use evocative pseudonyms. "Crispa," named after the Latin for curly-headed, which used crossword puzzles for the Guardian from 1954 to his retirement in 2004, legally changed his surname after divorce in the 1970s to "Crisp." Some pseudonyms have obvious connotations: for example Torquemada, as already described, or "Mephisto" with devilish nuances quite obvious.
