The term "like" serves multiple functions in the English language. It can be used as a verb to express enjoyment or preference, as in "I like chocolate." Additionally, it can function as a preposition to indicate similarity, such as in "She runs like a cheetah." In informal speech, "like" is often used as a filler word, helping to pause or emphasize a point. For example, someone might say, "I was, like, really surprised." This usage has become common among younger speakers, particularly in social media contexts, where it can convey emotion or relatability.
