Being concious of grammer makes one suseptable to being the company "proofreader". But it beats having the company put out something that sound like it was written by a 6th grader....
Indeed, you wouldn’t want to sounds like that. ;)
My former employer had a pile of flyers made for a major medical trade show that had the large print heading:
"YOUR DIGITALS SOLUTION"
The disgruntled sales staff and I had a good laugh about it since we had all figured out what a crooked bunch of idiots we were working for and started looking for better jobs at better companies. Had we not already been thoroughly disgusted by this sort of incompetence that infected the company from the president down, we would have never let the flyers come out of the box.
Insure only refers to the word insurance, such that you could buy. It's the difference between assure and ensure that I find difficult to teach.
