Can you begin a sentene with the word furthermore?

Answer 1

Yes, you can. You MUST add a comma after it, however, and then continue your sentence. In addition, it doesn't make sense to use the word 'furthermore' unless the previous sentence has some sort of relation to the sentence in which you use the 'furthermore'. Here is an example:

"Supernatural imagery is the fundamental device Brontë employs in indicating similarities and differences between Bertha and Jane in Jane Eyre. Furthermore, through the comparison of Bertha's monstrosity and Jane's ethereality, Brontë demonstrates the patriarchal repression of female desires."
