I had to wonder if this was a product of my dependence on my word program's spell checker, or if this was simply a word I got stuck on often. When I think about it, the latter is true. Professional writer or not, there are simply words that I always spell wrong, or have to think about how to spell no matter how many times I write or type them. Moreover there are some spellings which confound me. For instance, why is swimming spelled with a double 'm' but there's only one 'm' in coming? My hubby often misspells the word forward as foreward. Accidentally is another one I stuff up often, by spelling it accidently.
I found a list of commonly misspelled words here. Calendar is on the list, one I often find spelling calander before I realise how wrong that looks and change it. License is another. As the website quotes: "Where does English get the license to use both its letters for the sound [s] in one word?"
It's a funny language we work with, English. Don't even get me started on how mind-scrambling it can be to have books published with an American publisher and have to change all those 's's to 'z's and drop all my lovely 'u's. I was taught to spell colour not color, but that's a whole other bone of contention.
So what about you? Any words you always spell
