What's one word, phrase, or sentence construction that automatically gives a writer away as an amatuer to you? That makes you lose faith in their ability to use the English language? That just makes the story sound 'off'? I have tons, but a major one for me is exclamation points in prose. They don't make me feel excited, they make the writer sound sugar-high. I also dislike quantifiers like 'a few' or 'every so often', especially when using during a dramatic scene, because they make everything sound unimportant (the writer can't even be bothered to give specific numbers). Others?
