 Forms 
By Qaqaq

Forms are puzzles similar to crosswords; from given clues, the solver fits words into a pattern. The important difference is that form patterns are geometrical shapes and have no black squares, as crosswords do.

If the form is a shape described in this section, no blank diagram will be shown in The Enigma. The title and number of clues will be sufficient information to determine the form's shape exactly. For example, if the title is "SQUARE" and there are six clues, the words will be filled into a shape six squares across by six squares down. (This form would be called a 6-square. Forms' sizes are named for the length of their longest entries.) If the form is a shape not shown in this section, the editor will usually print a diagram showing the shape.

(Occasionally, the editor may also describe a new form type's shape via form notation; for example, a wedge-shaped form could be described as S:R. You will never be required to understand this notation to solve a form, but if you are interested you can find more details here.)

The varieties of basic types include inverted forms, bigram forms, vowelless forms, and many others. Explanations and examples of these are given in the "Types of Forms" section.

 Words Used in Forms

Forms are most popular when they consist mainly of common words and phrases. Often, though-particularly in larger forms-the form constructor (or formist) might need to resort to unusual words to finish the form. Form words may come not only from the standard NPL references but from any English-language source. Solvers may get credit for incompletely solved forms containing words not found in any standard NPL reference and not easily inferable from context. (While formists are allowed to use these words, form solvers are not always required to find them.)

Historically, formists were not allowed to use abbreviations, partial phrases (for example, ETAT clued as "Coup d'___"), or foreign words. In recent years, Enigma forms have contained all of these. Some people (myself included) do not consider forms containing these sorts of entries to be legitimate; others, seeing forms as similar to crosswords, have no problem with them. Formists must decide this question for themselves.

Prohibited words include all those listed in NI2 only as "reformed spelling." The reformed spelling movement was a brief, unpopular phenomenon, and while the NI2 editor was trying to popularize those spellings by including them, they never gained wide acceptance. For this reason, formists have never felt free to use those spellings, and they are banned from all types of Enigma puzzles.

 Submitting Forms
  1. If a word is in any current NPL reference, it is generally not tagged unless the forms editor feels that information is necessary (for example, in some harder puzzles such as vowelless or consonantless forms).
  2. Non-MW words are welcome in forms. However, the constructor should make every possible effort to find some printed source in which the word can be found: for instance, a current almanac, a movie guide, or a specific issue of a magazine. (Online sources, due to their varying degrees of accuracy, are not acceptable.) While this may seem a slight inconvenience to the constructor, remember that a solver who doesn't know the word is forced to search for a source in order to confirm it.
  3. If the word is MW but tagged "rare" or "archaic," include that in the clue after a colon. For example, the 11C word ABY could be clued as "Suffer a penalty: arch."
  4. If the word is MW as a variant of another word, and the normal spelling is tagged, that tag should also be included. For example, the NI2 word AGRAW is listed as a variant of the word AGRAH, which is defined as "Dear; sweetheart" and tagged "Anglo-Irish." A proper clue for AGRAW, then, would be something like "Sweetheart: Anglo-Irish, var."
  5. If the word is not MW, put its source in parentheses after the clue. For example, the Chambers word SOARE, defined as "Reddish-brown," would be clued as "Reddish-brown (Cham.)."
  6. If the word is not MW and also has a tag such as "rare" or "archaic," put the source last. For example, SELAD is in OED as a variant form of SALAD. It could be clued as "Vegetable dish: var. (OED)"
  7. If a non-MW word is very obscure, it may be given to the solver; this is done by putting the word in all capitals, followed by a source tag: "ARINES (NI1)." It is not necessary to provide the definition.
  8. As an aid to the solver, if the word is an obscure Biblical name or is out of place in the dictionary, include the source and page number on which the word is shown: "Biblical name: NI2, page 731."
  9. Submit clues in Enigma format: start each clue on a separate line.
  10. So that the form checker doesn't have to shuffle among the various MW references, include the specific references where you found any unusual words or definitions.
  11. Remember to include the answer!
