Writing Challenges
Lipograms are popular constrained writing techniques used in classic literature and poetry:
- E-less Novels: Writing without using the letter "E" is the most famous challenge, popularized by Georges Perec's 300-page novel A Void (La Disparition).
- Univocalics: Writing pieces that restrict all but a single vowel (e.g. only using the vowel "O" in all words).
- Consonantal Restrictions: Crafting texts that completely omit specific high-frequency consonants to change phonetics and word flows.
FAQs
What is a lipogram?
A lipogram is a piece of writing that deliberately avoids one or more letters of the alphabet. Famous examples include Georges Perec's novel 'La Disparition' which avoids the letter 'E'.
How does the Lipogram Checker work?
Enter your text and specify which letters to avoid. The checker will analyze if your text contains any of those forbidden letters and report the violations.
How does the Rewriter work?
The rewrite function removes all occurrences of the forbidden letters from your text. This is a literal deletion, not an intelligent substitution.
What are stopwords and why would I avoid vowels?
Vowels (a, e, i, o, u) are frequently used in English. Creating a text without vowels is an extreme writing challenge. The tool helps you check if you've accidentally used forbidden letters.
Can I check for multiple forbidden letters at once?
Yes, enter all the letters you want to avoid in the forbidden letters field without spaces. For example: 'aeiou' to avoid all vowels, or 'bcdfghjklmnpqrstvwxyz' to only allow vowels.
