Tongue twisters are amusing logical or illogical sentences with the goal of making it difficult to articulate each word correctly. The amusement from tongue twisters stem from the difficulty that the speaker experiences from saying them. Often, these tongue twisters have alliterations (a string of words with the same letter sound), or phonemes with similar but distinct sounds (the /s/ and the /sh/ sound). The success from these tongue twisters comes from pronouncing them both clearly and correctly. Interested in hearing or learning an international tongue twister?
