I was recently asked a great question from someone working with my teacher resource book, "Teaching How the Written Word Works". In one of the lessons a studnet suggested a word from a matrix that the teacher was not sure was a word and was wondering how people deal with that question.
This turns out to be a super rich question to investigate. I created a doucument that you can download from THIS LINK which shows where in the text of my book that I address this question that always comes up. I also add more context, and even the page from my book with the matrix that provoked the question in the first place. So you don't need the book for this to be a useful post.
The screen shot below is of the first page of this 3 page document.
