They are the unavoidable, almost mandatory errors we make when writing. I’ve caught them in emails, college textbooks, even in an international bestselling book. And you’d think after undergoing a sequence of rereads and edits, followed by a critique’s red pen marks splattered all over the page, perhaps because Freddy Krueger has just been assigned as your editor, this simply wouldn’t happen.
But it still does. It’s bound to happen to us all. We are all, and always will be, victims of the slipping finger. The question is: What is to be done about it?
As a writer myself, I should say that absolutely no person is more critical to a book than the authors themselves. We’ve reworded our pages enough times to make our fingertips sore, extended chapters, extracted characters, replaced scenes and scenarios for bigger and better ones, etc., etc. Yet despite our efforts to a maximized refined manuscript, we find that we have either duplicated or missed, misspelled or misused (And if you happen to be very unfortunate, all four in one).
By this, I cannot stress the profound importance of having a fresh pair of eyes examine your manuscript (Or whatever it is you’re writing). What they will be reading is new to them, so every word counts, even the little ones. Nonetheless, we are still humans. Even the highest-paid editors and publishers with decades of experience may fall into this error.
Hope this helped console you for your troubles.
