This is me cashing in on a) public service announcements, b) pedantry, and c) media bashing.
Here is a word: enormity.
Here's what the word enormity means in the OED: 1 extreme wickedness. 2 an act of extreme wickedness. 3 a serious error. 4 disp. great size; enormousness.
See the disp. next to #4? This requires, in my dictionary, an explanation. Here is that explanation: Usage The use of enormity in sense 4 is often found, e.g. the enormity of the problem, but is regarded as incorrect by many people.
Just in case my dictionary is flawed I googled and came up with this and this and this.
Now, given the first three meanings and the usage problem mentioned in regard to #4 one would think that people would approach this word with caution and, perhaps, use it appropriately - preferably when they want to invoke the word's other meanings. One would think...but then this is a word that one approaches with caution. Not so the media. I've often heard it used inappropriately recently but not to such amusing effect as on the news earlier when newsman spoke of the enormity of some little actors re-enacting a rather boring biblical scene. They were, apparently, overcome with the enormity of their act. The enormousness, apparently, though the case could very well be made for the other.
