(This may have been covered previously B.K.)

I know that I have been mispronouncing "iron, irony, ironing, etc.". My wife has been correcting me for years. I have been saying "I-ron" instead of "I-ern". I pointed out to her that it is peculiar that we don't pronounce "Ironic" the same as we do "Irony". Though I'm not a linguist, I'm sure it has something to do with there being a vowel after the "N". But what about "Ironist", or "Ironing", they have the "ern" sound.

As an aside, Alanis Morissette's Ironic is really a series of unforntunate incidents. Poor gal!
