Straight or quick[edit]
Some crossword clues, called straight or quick clues, are simple definitions of the answers. Some clues may feature anagrams, and these are usually explicitly described as such. Often, a straight clue is not in itself sufficient to distinguish between several possible answers, either because multiple synonymous answers may fit or because the clue itself is a homonym (e.g., "Lead" as in to be ahead in a contest or "Lead" as in the element), so the solver must make use of checks to establish the correct answer with certainty. For example, the answer to the clue "PC key" for a three-letter answer could be ESC, ALT, TAB, DEL, or INS, so until a check is filled in, giving at least one of the letters, the correct answer cannot be determined.
In most American-style crosswords, the majority of the clues in the puzzle are straight clues,[citation needed] with the remainder being one of the other types described below.
Crossword clues are generally consistent with the solutions. For instance, clues and their solutions should always agree in tense, number, and degree.[2] If a clue is in the past tense, so is the answer: thus "Traveled on horseback" would be a valid clue for the solution RODE, but not for RIDE. Similarly, "Family members" would be a valid clue for AUNTS but not UNCLE, while "More joyful" could clue HAPPIER but not HAPPIEST.
Some clue examples:
Fill-in-the-blank clues are often the easiest in a puzzle and a good place to start solving, e.g., "_____ Boleyn" = ANNE.
"Before and after" clues feature one word that is part of two phrases, often designated with parentheses and brackets, e.g., (Doing [____) keeper] = TIME.
A question mark at the end of clue usually signals that the clue/answer combination involves some sort of pun or wordplay, e.g., "Grateful?" = ASHES, since a grate might be full of them.
Most widely-distributed American crosswords today (e.g., The New York Times, Washington Post, Boston Globe, USA Today, etc.) also contain colloquial answers, i.e., entries in the puzzle grid that try to replicate everyday colloquial language. In such a puzzle one might see phrases such as WHAT'S UP, AS IF, or WHADDYA WANT.
In the hands of any but the most skilled constructors, the constraints of the American-style grid (in which every letter is checked) usually require a fair number of answers not to be dictionary words. As a result, the following ways to clue abbreviations and other non-words, although they can be found in "straight" British crosswords, are much more common in American ones:
Abbreviations, the use of a foreign language, variant spellings, or other unusual word tricks are indicated in the clue. A crossword creator might choose to clue the answer SEN (as in the abbreviation for "senator") as "Washington bigwig: Abbr." or "Member of Cong.", with the abbreviation in the clue indicating that the answer is to be similarly abbreviated.[3] The use of "Var." indicates the answer is a variant spelling (e.g., EMEER instead of EMIR), while the use of foreign language or a foreign place name within the clue indicates that the answer is also in a foreign language. For example, ETE (été, French for "summer") might be clued as "Summer, in the Sorbonne". ROMA could be clued as "Italia's capital", whereas the clue "Italy's capital" would indicate the English spelling Rome.
The eight possible abbreviations for a position on a compass, e.g., NNW (north-northwest) or ESE (east-southeast), occur with some frequency. They can be clued as simply "Compass point", where the desired answer is determined by a combination of logic—since the third letter can be only E or W, and the second letter can be only N or S— and a process of elimination using checks. Alternatively, compass point answers are more frequently clued as "XXX to YYY direction", where XXX and YYY are two place names. For example, SSW might be clued as "New York to Washington DC dir". Similarly, a clue such as "Right on the map" means EAST. A clue could also consist of objects that point a direction, e.g., "vane dir." or "windsock dir.".
Roman numerals, and arithmetic involving them, frequently appear as well; the clue "IV times III" (4×3) would yield XII (12).
In addition, partial answers are allowed in American-style crosswords, where the answer represents part of a longer phrase. For example, the clue "Mind your _____ Qs" gives the answer PSAND (Ps and).
Non-dictionary phrases are also allowed in answers. Thus, the clue "Mocked" could result in the grid entry LAUGHED AT.
