The phrase "such as" is used to introduce examples that clarify or illustrate a point. It helps to specify particular items within a broader category, making the information more relatable and understandable. For instance, when discussing fruits, one might say, "I enjoy tropical fruits, such as mangoes, pineapples, and bananas." Using "such as" can enhance writing by providing concrete examples that support the main idea. It allows the reader to grasp the context better and see how the examples fit into the overall discussion. For example, "Many animals, such as dogs and cats, are popular pets."
