A tongue twister is a phrase, sentence, or rhyme that presents difficulties when spoken as it contains similar sounds—Whistle for the thistle sifter, for example. To get the full effect of a tongue twister, you should try to repeat it several times as quickly as possible without stumbling or mispronouncing.
