Furthermore, Moreover, In Addition


These transitional adverbs are used to add information to what has already been said. Note that moreover and furthermore are mainly used in a formal style. In a less formal style, we use other transitional adverbs such as what is more, on top of that, in addition and besides.

Transitional adverbs always come at the beginning of a sentence and are followed immediately by a comma. They do not become a grammatical part of the sentence. In fact, they are cohesive devices that writers employ to show how ideas flow between sentences and paragraphs.
