Peter Piper is a merry tongue-twister that uses alliteration to make the sentences tricky to pronounce. It was first published in 1813 in Peter Piper’s Practical Principles of Plain and Perfect Pronunciation. In this book, a tongue twister was published for every letter of the alphabet, but Peter Piper is the one that has endured.
The similarity of lyrics is so similar that it makes it hard for anyone to repeat the rhyme multiple times in a row without making a mistake which is part of the fun of repeating it with friends to see how many times it can be said correctly without slipping up.
The Peter Piper Principle is now used as an official phrase to describe a situation where a person gets two similar things confused because the words sound alike. Authors are often advised not to give different characters names that start with the same letter because of the Peter Piper Principle!
Peter Piper Lyrics
Peter Piper picked a peck of pickled peppers,
A peck of pickled peppers Peter Piper picked;
If Peter Piper picked a peck of pickled peppers,
Where’s the peck of pickled peppers Peter Piper picked?
