Idioms are important in English as they make the language more colorful and aid in efficient communication. They also help people feel a sense of cultural belonging by understanding nuances beyond just rules. While idioms can be challenging initially, regular practice and exposure helps develop understanding over time. Idioms are commonly used in both written and spoken English and indicate a level of proficiency among native speakers. Mastering idioms is also useful for exams and higher education opportunities where idiomatic competence is evaluated. Regular practice builds confidence in incorporating idioms into conversational English.
