The earliest version of this tongue-twister was published in Peter Piper's Practical Principles of Plain and Perfect Pronunciation by John Harris (1756–1846) in London in 1813, which includes a one-name tongue-twister for each letter of the alphabet in the same style. However, the rhyme was apparently known at least a generation earlier.[3] Some authors have identified the subject of the rhyme as Pierre Poivre, an eighteenth‑century French horticulturalist and government administrator of Mauritius, who once investigated the Seychelles' potential for spice cultivation.[4][5]
Peter Piper Principle
The Peter Piper Principle is a cognitive error that people make, where they tend to confuse two words that resemble each other; in particular, when the first letter(s) are the same. Studies have shown that this applies when people confuse the names of other people (although other tendencies also apply).[6][7]
Novelists are well aware of the peril of giving two characters names that start with the same letter, because readers have a tendency to get them confused.[8][9] Names of medications also tend to be confused when they start with the same few letters.[10]
