Bet you had a hard time explaining that one!
We had a wonderful spell-checker years ago. Being a headmaster's daughter, a linguist and a pedant to boot, I used to make sure my letters were spelt correctly etc. I was surprised that the secretary kept returning them with incorrect spellings in obvious words, and words that I'd spelt correctly in the first place. When I asked her about this - she was copy typing - she explained that her pc used spell-check and automatically corrected certain words, no matter how they were typed in the first place.
I then asked her about the spell-check dictionary, wondering what kind of dictionary could spell as badly as this one apparently did. "Oh, it doesn't have a dictionary, " she said "I just type the words into spell-check myself."
So that explained it
