In addition

You usually put it at the very start of a sentence. Always follow it with a comma. This gives the reader a tiny breath before the new info. For example: "The hotel was clean. In addition, the staff was very friendly." You can also use it in the middle of a sentence with to. Like this: "In addition to the rain, it was very cold."

Use it when you want to sound smart and organized. It is perfect for business emails or cover letters. It works great in school essays or during a job interview. If you are listing benefits of a product, this phrase is your best friend. It makes your argument feel solid and well-planned. It shows you have a clear logical flow.

Do not use it while texting your best friend about a pizza. It sounds a bit too stiff for a casual chat. "The pizza is hot. In addition, it has extra cheese." Your friend might think you are a robot! Also, avoid using it five times in one paragraph. It gets repetitive quickly. If you have already used it once, try a different word next time.

English speakers love structure in formal writing. We use these "signposts" to guide the reader through our thoughts. It is a hallmark of a "polished" or "educated" speaker. In Western logic, we like to stack evidence to prove a point. In addition is the glue that holds those points together. It has been a staple of formal English for centuries.

You might hear people say Additionally or Also. If you want to sound even fancier, try Furthermore or Moreover. If you are just hanging out with friends, you will probably just say Plus or And. Each one changes the "vibe" of the sentence slightly. In addition sits right in the sweet spot of professional and clear.
