I reviewed a book a few months ago that every single time the main character smelled something (which oddly, for any story, was a lot), he smelt it.
The first time I saw it, I chuckled…the 6th time I saw it, I knew this writer had no idea how to find and hire an editor.
The story was great; but I could not get past the smelt-situation. There were other spelling and sentence errors, but they seemed like nothing compared to this.
This, my friends, is why you should not trust your spell-checker 100%.
You can smell something (verb), or something can smell. You can never smelt something, because it is a fish, and I am not a veterinarian, but I believe the sense of smell in a fish has something to do with the gills, and amount of oxygen in the water. Honestly, I am not even sure if they can “smell” anything.
Just save yourself the hassle, and your readers the pain, and find a great editor. We really are nice people who only want to help 🙂
