I remember being taught in school that you shouldn't start a sentence with a conjunction in formal writing. I don't know what falls into the category of "formal" writing (business correspondence?) but it seems to me that this rule is either lax in novel writing or it has simply become lax in general.
I'm speaking of, in particular, the conjunctions "and" and "but" which seem to beg me quite often to place them at the forefront of my sentences. I am quite guilty of starting many sentences with one or the other. It's part of my writing style. But, (and here I go!) each time I do there is a portion of my brain that pauses and wonders if I should be limiting myself. Is this something an editor would cringe at or is it truly acceptable in the publishing industry?
So my questions for the day are: Does anyone have educated insight on this question? And, do you, as writers, ever use conjunctions as sentence starters in your own writing? Often? What are your thoughts on this?
