I have thirty years experience in administration and using language in a professional context. I have a qualification in copy-editing and proofreading, a first-class degree in literature and am interested in cognitive poetics and cognitive linguistics.
I am trying out this stackexchange thing because I have used it to find answers in the past and thought I would give something back. The questions are always open to debate when English grammar is concerned, which makes it very interesting discussing the difficultie. In my experience grammatical rules are a starting point for discovering when something is philosophically or morally conflicted - one can always tell when something sounds right, but appears to go against the rules of grammar. English grammar is a question of morals and ethics not just the way to construct a sentence - the way we construct sentences is not just representative of the way we think about ourselves and others - it is integral to how we perceive and conceptualise ourselves in relation to others.
