In poetry, formal constraints abound in both mainstream and experimental work. Familiar elements of poetry like rhyme and meter are often applied as constraints. Well-established verse forms like the sonnet, sestina, villanelle, limerick, and haiku are variously constrained by meter, rhyme, repetition, length, and other characteristics.
Outside of established traditions, particularly in the avant-garde, writers have produced a variety of work under more severe constraints; this is often what the term "constrained writing" is specifically applied to. For example:
Mandated vocabulary, where the writer must include specific words (for example, Quadrivial Quandary solicits individual sentences containing all four words in a daily selection).
Bilingual homophonous poetry, where the poem makes sense in two different languages at the same time, constituting two simultaneous homophonous poems.[2]
Twiction: espoused as a specifically constrained form of microfiction where a story or poem is exactly 140 characters long.
Sijo: three lines average 14–16 syllables, for a total of 44–46: theme (3, 4,4,4); elaboration (3,4,4,4); counter-theme (3,5) and completion (4,3).
Notable examples
Ernest Vincent Wright's Gadsby (1939) is an English-language novel consisting of 50,000 words, none of which contain the letter "e".
In 1969, French writer Georges Perec published La Disparition, a novel that did not include the letter "e". It was translated into English in 1995 by Gilbert Adair. Perec subsequently joked that he incorporated the "e"s not used into La Disparition in the novella Les Revenentes [fr] (1972), which uses no vowels other than "e". Les Revenentes was translated into English by Ian Monk as The Exeter Text: Jewels, Secrets, Sex.
Perec also wrote Life A User's Manual using the Knight's Tour method of construction. The book is set in a fictional Parisian block of flats, where Perec devises the elevation of the building as a 10×10 grid: 10 storeys, including basements and attics and 10 rooms across, including 2 for the stairwell. Each room is assigned to a chapter, and the order of the chapters is given by the knight's moves on the grid.
"Cadaeic Cadenza" is a short story by Mike Keith using the first 3835 digits of pi to determine the length of words. Not A Wake is a book using the same constraint based on the first 10,000 digits.
Ella Minnow Pea is a book by Mark Dunn where certain letters become unusable throughout the novel.
Alphabetical Africa is a book by Walter Abish in which the first chapter only uses words that begin with the letter "a", while the second chapter incorporates the letter "b", and then "c", etc. Once the alphabet is finished, Abish takes letters away, one at a time, until the last chapter, leaving only words that begin with the letter "a".
Mary Godolphin wrote versions of Robinson Crusoe, Aesop's Fables, The Swiss Family Robinson, and other books using only monosyllabic words.
Zero Degree is a postmodern lipogrammatic novel written in 1998 by Tamil author Charu Nivedita, later translated into Malayalam and English. The Tamil words "oru" and "ondru" (the English equivalents are "a", "an" and "one") have not been mentioned anywhere in the novel, except one chapter. Keeping with the numerological theme of Zero Degree, the only numbers expressed in either words or symbols are numerologically equivalent to nine (with the exception of two chapters). This Oulipian ban includes the very common word one. Many sections of the book are written entirely without punctuation, or using only periods.
Uruguayan musician, comedian and writer Leo Maslíah's 1999 novel Líneas (Lines) is written entirely with paragraphs comprising a single sentence.
The 17th-century Odia poet Upendra Bhanja wrote multiple epics (Satisha Bilasa, Kala Kautuka, Baidehisha Bilasha, etc.) with the same syllable at the beginning of each sentence.[clarification needed]
Gustave Verbeek's The Upside Downs of Little Lady Lovekins and Old Man Muffaroo, a weekly 6-panel comic strip in which the first half of the story was illustrated and captioned right-side-up, then the reader would turn the page up-side-down, and the inverted illustrations with additional captions describing the scenes told the second half of the story, for a total of 12 panels.
The Angriest Dog in the World a comic strip by David Lynch. Each four-panel comic has identical artwork. The only change between each comic is the dialogue in the first three panels.
Dinosaur Comics which uses the same artwork, with only dialogue changing.
Watchmen is created with a number of formal constraints; issue #5 in particular, entitled "Fearful Symmetry", follows a palindromic structure.
^Bilingual Homophonous Poetry – Italo-Hebraic Bilingual Homophonous Poem by linguist Ghil'ad Zuckermann, in which the Hebrew poem sounds identical to the Italian one, both making full sense – see Zuckermann, Ghil'ad (2006), "Shir Du-Leshoni" (Bilingual Poem), Ho!, Literary Magazine 3, pp. 256–257.
Mike Schertzer, in Cipher and Poverty (The Book of Nothing), created a three-level acronymic poem. Beginning with a name a verse was created for which the name was the acronym. This verse was then expanded, and then again. The final verse is 224 words long (which means the previous verse, its corresponding acronym, contains 224 letters).
