furthermore
In addition; used to add another important point.
Furthermore is a formal word that means “in addition” or “besides.” When you're building an argument or explanation and want to add another supporting point, furthermore signals that you're strengthening your case with more evidence.
Imagine you're trying to convince your parents to get a dog. You might say: “A dog would teach me responsibility. Furthermore, studies show that kids with dogs get more exercise.” That second sentence adds weight to your argument.
Furthermore works like moreover, additionally, or “what's more,” but it sounds more serious and structured. You'll see it often in essays, formal speeches, and persuasive writing. A scientist might write: “The experiment succeeded three times. Furthermore, each trial produced consistent results.”
In conversation, people usually choose simpler words like “also” or “plus.” You wouldn't tell your friend, “I like pizza, and furthermore, I enjoy tacos.” That would sound oddly stiff. But in a class presentation or formal letter, furthermore fits perfectly. It shows you're organizing your thoughts carefully and leading your audience through your reasoning, point by point.
