The word "moreover" is a transitional phrase used to add information or emphasize a point in writing or speech. It helps to connect ideas by indicating that the following statement builds on or reinforces the previous one. For example, if someone says, "The project is behind schedule; moreover, it is over budget," they are highlighting two related issues. In academic and formal writing, "moreover" is often used to enhance the clarity and flow of arguments. It signals to the reader that additional evidence or reasoning is being presented. This can be particularly useful in essays or reports discussing topics like climate change or economic policies.
