Name a common transition word that indicates addition in writing.

The word "furthermore" is a common transition word that indicates addition in writing. It is used to introduce an additional point or piece of information that supports or builds upon the previous statement. This type of transition is important for creating coherence and flow in writing, as it helps the reader to see the connections between different ideas or arguments being presented.

When used effectively, "furthermore" signals to the reader that more information is coming that contributes to the subject at hand, thereby enhancing the overall clarity of the text. This word is often employed in academic or formal writing where additional support for an argument is necessary.

In contrast, other transition words like "however" and "consequently" serve different purposes; "however" introduces a contrast or exception, while "consequently" indicates a result or conclusion. "Meanwhile" suggests simultaneous actions or events rather than addition. Thus, "furthermore" stands out as the appropriate choice for indicating an additive relationship in writing.
