Correct Pronunciation

[robb_k]

Somehow, because I've been hearing the sentence in my head, I can see that you are correct. I ALWAYS write, "It should be SPELLED, thusly." So, why would the usage change when the word "thusly" is added? Now, "It should be spelt, sounds very wrong. Maybe I was influenced by the "s-p-e-l-t" being adjacent to it?

I also notice that things I thought were one way all my life are now different. But maybe that is just neurons misfiring?
