Idioms and Phrases

Idioms and phrases are expressions with figurative meanings that differ from the literal definitions of their individual words. They are essential components of English communication, often rooted in history and culture, and serve to make language more engaging, descriptive, and expressive. Examples include "a piece of cake" for a simple task or "hit the nail on the head" for being exactly right.
