Can "hence" be used at the beginning of a sentence?

Question

Can the word ‘hence’ be used at the beginning of a sentence? For example: > Hence, I am not feeling well, I am unable to work.

Answer 1

Yes, it can. The word “hence” indicates that a conclusion is being drawn or inferred from other information in the same way that the word “therefore” indicates this, so it can be used in the same way. So for example, instead of saying, “My client was nowhere near the scene of the crime on the night of the murder. Therefore, she wasn’t the murderer.” you could say, “My client was nowhere near the scene of the crime on the night of the murder. Hence, she wasn’t the murderer.”

Answer 2

I think what you mean is:

I am not feeling well. Hence, I am unable to work.

These are two independent clauses and should not be joined/separated with a comma.
