When I see the words business advisor across the front of an accounting practice I simply shudder. How could a professional business not take the time and effort to check out the spelling for a major part of their advertising. The use of the word advisor is now so common that it is more common than the correct spelling adviser. In time that probably means by default the incorrect spelling will become the correct spelling and to me that's a shame. It isn't the general public, but a specific group of businesses using the wrong spelling that leads us to believe it is the right spelling.
Not exactly on topic, but when I saw this very large sign on the wall of a shop in Thomastown, it did make me wonder. The accounting firm has spent a considerable amount of time and money getting a very large sign attached to the side wall of a shop which has great traffic visibility in two directions. At no time does it appear the accountant bothered to check the spelling of the word bookkeeping, which is spelt incorrectly as bookeeping. Even if they did, then they're more than happy to leave the sign up for years with the spelling error. How accurate and caring of your critical business information do you think this accountant would be when they don't even care about their own advertising?
Spelling often provides us with clues which I think are certainly worth looking for, and can often provide us with information the supplier probably wouldn't want us to know. Whilst spelling may not be the deal breaker in a final decision, for me it puts the business on the back foot and this simply makes it harder for them to get my business.
Don't let poor spelling affect your chances of getting business, a better grade for your assignments, or perhaps even that job promotion. Life can be tough so don't make it tougher than it need be. If in doubt, pick up a dictionary and verify the spelling of the word. Using the internet generally isn't a great idea as the spelling tools available are mostly overseas based and thus not the best for Australia.
