Commentate and coronate.
Or maybe I should say they irritATE the hell outa me!
Anyway, commentators don't commentate. They comment. And kings don't get coronated. They get crowned!
Then, another current verbal crime that irritates me no end is the constant repitition on TV news of the term humanitarian crisis:
For example, a crisis like the current "ethnic cleansing" of Christians in the Middle East is an absolutely terrible happening, a disaster of Biblical proportions. How on earth can anybody with even a tiny bit of logical ability in his brain describe it as humanitarian? The term is really a ne plus ultra case of oxymoronism.
I also hate “conversate.”
