Input: "reading". The first letter r and last letter g stay put, and the middle letters eadin are shuffled, so one possible result is "raednig". Every press produces a different arrangement, and words of three letters or fewer never change.
- Only the letters inside each word move; punctuation, spacing and capitalization stay where they were.
- Words of four letters swap their two middle letters at most; the effect grows with longer words.
- The shuffle uses the Web Crypto random source, not a predictable pattern.
Readers rely heavily on word shape, first and last letters, and context. The demonstration is often credited to Cambridge research, though that claim itself is an internet legend; the readability effect is real, the citation is not.
