Lots of tongue twisters use alliteration.
A good way to remember what alliteration means, is to think of the word "repetition." "Alliteration" and" repetition" even sound alike! Alliteration is the repetition of the same first letter or sound in a group of words. Simple, right? Not all the words in a sentence have to start with the same letter or sound for there to be alliteration, but a good chunk of them should. Alliteration is also easier to spot when the words that sound the same sit next to each other in sequence, but it's not required. Did you catch the alliteration in the sentence before this one? If you did, congrats. You're on your way to becoming an alliteration pro.
