The phrase in addition is a linking expression used to introduce extra information, support a point, or add another reason to something you have already said. It functions as a formal transition that signals to your reader that you are about to present something supplementary. In writing, it helps you build arguments, list supporting details, or expand an idea without starting a completely new topic. Whether you are drafting an academic essay, a business email, or a formal report, in addition is a reliable tool for connecting related thoughts clearly.
Quick Answer: What Does “In Addition” Mean?
In addition means “also,” “furthermore,” or “as well as.” You use it to add a new piece of information that supports or extends the previous statement. It is most common in formal and semi-formal writing, though it can appear in careful spoken English. For example: The training covers basic grammar. In addition, it includes practice exercises.
Formal vs. Informal Tone
Understanding when to use in addition depends heavily on tone. Here is a quick breakdown:
- Formal writing (essays, reports, business proposals): In addition is a standard, professional choice. It sounds structured and deliberate.
- Semi-formal writing (emails to colleagues, blog posts): It works well, though you might also use also or plus for a lighter feel.
- Informal writing or conversation (texts, casual chats): In addition can sound stiff. Use also, too, or and instead.
For example, in a formal email you might write: We have revised the budget. In addition, we have updated the timeline. In a casual conversation, you would say: We revised the budget, and we updated the timeline too.
