The phrase "for example" is used to introduce a specific instance or illustration that clarifies a broader concept. It helps to provide context and make abstract ideas more relatable by showing how they apply in real-life situations. In writing and speech, "for example" often precedes a detailed explanation or a list of items. For instance, if discussing fruits, one might say, "Many fruits are rich in vitamins; for example, oranges and kiwis are excellent sources of vitamin C." This usage enhances understanding by providing concrete examples.
