The squiggly red line failed to appear. Apparently, both spellings were correct. But they couldn’t be, surely. I looked back at my handwritten notes, where “focusing” spelt with a single “s” looked just fine to me. At school, spelling was never my strong suit, but a love of writing (and the tendency to write on paper, without the benefit of spellcheck) means I’m now pretty good at it.
Still, I make mistakes, and it was comforting the day I found out that even the great Jane Austen didn’t always get it right. Maybe, even Shakespeare’s famed invention of words sprang from gaps in memory or inattention to detail.
