What Does “Additionally” Mean?
Additionally is an adverb meaning “also,” “in addition,” or “as another point or fact.” It is used when introducing information that supplements something already mentioned.
Example:
The course is affordable. Additionally, it offers flexible evening classes.
Here, additionally signals that the second sentence provides another positive fact about the course.
The word is especially common in formal writing, business communication, academic prose, reports, presentations, and informational content.
Its basic semantic function is simple:
Existing information + additionally + new information
However, choosing an alternative can change the rhythm, emphasis, formality, or relationship between the two ideas.
The Additionally Synonym Hierarchy
Not every synonym for additionally performs exactly the same job. A useful way to choose among them is to place alternatives on a meaning-and-register spectrum.
Simple addition → stronger addition → argumentative reinforcement
also → in addition → moreover → furthermore
And for conversational English:
also → besides → plus → on top of that
This distinction matters because replacing additionally with moreover, for example, may make a sentence sound more argumentative than the original.
