Tongue twisters are phrases or sentences that are designed to be difficult to articulate quickly and clearly. They often feature similar sounds or repetitive syllables that challenge the speaker's pronunciation skills. Common examples include phrases like "She sells seashells by the seashore" and "Peter Piper picked a peck of pickled peppers." These playful linguistic challenges are often used in speech therapy, language learning, and as a fun activity among friends. They can help improve diction, fluency, and overall speech clarity. Many people enjoy practicing tongue twisters as a way to enhance their verbal skills while having fun.
