I’ve read so many books during my life that I’ve started to misspell words. I’ll give you a minute to think about that.
I didn’t pay attention to which books were written by English authors and which by American authors. There must have been a time when my selections were top heavy with Brits because I started dropping a U into words that Microsoft Word kept underling, claiming that a U didn’t belong in said word. When it happened with the word color, well, that one seemed rather obvious.
Then came a day when Word underlined realise. I couldn’t figure out what was wrong. I kept re-reading the sentence for grammar and content to make sure it wasn’t a fragment, etc., etc. But wait, the underline was red, squiggly, and mocking. What in the world was wrong with this word?
I deleted it, retyped it, and again the ugly red squiggles popped up. It was time to resort to the good ole Google search bar. When the first article to pop up was titled Realise vs. Realize, I had a sneaky suspicion of the mistake I’d made. I was having my own private British Invasion.
According to Grammarist.com:
Realise and realize are different spellings of the same word, and both are used to varying degrees throughout the English-speaking world. Realize is the preferred spelling in American and Canadian English, and realise is preferred outside North America. The spelling distinction extends to all derivatives of the verb, including realised/realized, realising/realizing, and realisation/realization.
None of this may seem relevant to a writer, but on the off chance your writing includes a letter composed by someone born and raised outside of North America, think how smart you’ll look to your editor when you spell realize with an S.
