Can one start a sentence with however? Is it grammatically correct?
I didn't think it was that simple since however is an adverbial conjunction. I thought adverbial conjunctions must follow a semicolon. I heard there was a controversy a bout however in grammatical circles. I don't know why, but that a faction of grammarians believed it should be acceptable to start a sentence with however. Has the controversy been resolved to allow however to start a sentence? What about the other adverbial conjunctions starting a sentence?
There is a controversy only among people who get upset by this sort of thing. I don't. I have no time for to people who happily invent rules for which I can see no justification.
The ony valid 'rules' of English are those based on observation of what people actually say and write. With 49,802 citations of 'however' beginning a sentence in the Corpus of Contemporary English, I will pay no attention to anyone claiming that this is not acceptable.
However difficult it may be to accept it is still acceptable.
