"Finally" is an adverb used to indicate that something has happened after a long wait or delay. It often conveys a sense of relief or conclusion, marking the end of a process or the arrival of a long-anticipated event. For example, one might say, "Finally, the movie I wanted to see is available for streaming." In writing, "finally" can also serve as a transition word, helping to guide readers through a sequence of ideas or events. It is commonly used in lists or narratives to introduce the last point, such as, "We visited the museum, enjoyed lunch at a café, and finally, went for a walk in the park."
