Good call. You could argue for epenthesis, that she was going for normalcy and stuck the i in there. But there aren't many conditions in English, at least in North America, that have that kind of epenthesis. But you could also argue that she was trying to say normality and swapped the t for a c. In that case, it'd be a little more complicated, but would have something to do with feature swapping on the phonological level. On the sociolinguistic level, it would also indicate that she didn't know which was the correct form, but had some inkling she was off.

I'd have a hard time making a completely convincing case for either. This is why I'm not doing a Ph.D. in linguistics; people write dissertations on things just like this. Did you happen to take a stylistics course in grad school?
