The word "therefore" is a conjunction used to indicate a conclusion or result based on previously stated information. It connects ideas by showing that one statement logically follows from another. For example, if it is raining, you might say, "It is wet outside; therefore, you should take an umbrella." In writing and speech, "therefore" helps clarify reasoning and enhances the flow of arguments. It is commonly used in academic and formal contexts, such as essays or reports, to guide readers through the logic of the discussion. Using therefore effectively can strengthen the persuasiveness of your communication.
