[Sonia]

noun.
1: An exclamation that the other person is in fact incorrect. May only be exclaimed before correcting the other persons mistake, that is to say, when you as the speaker know how to correct the other persons mistake. In effect, the person proclaiming incorrection in fact proceeds to make a correction.
There are various ways that the word may be pronounced.
It may be pronounced just as it is presented phonetically in English. However, it is preferred to modify the pronunciation of the word and not speak it phonetically, and to give the word ones own unique quality.
It is highly recommended to pronounce the letter R in the word as the letter W (incowection!).
The tion syllable in the word may be pronounced as though speaking French, with the tion being dragged out. Or the whole word may be pronounced as though it were French.
The speaker should relish every opportunity that he/she has to appropriately use the word.
2: The word may also be used pedantically when the other person is not necessarily wrong, and you are simply correcting a minor detail that the other person has made. However, this is not a very sensible use of the word and such word usage should be avoided.
