I try not to let small things bother me, and occasionally I’m successful.
Before anyone asks what I mean by pedantry, I adopt the standard Oxford dictionary definition:
n. excessive concern with minor details and rules.
So don’t bother to comment that I’m being petty, or that the rising tide of illiteracy is against me, or (God forbid) point out my own mistakes. If we have a deal, I shall try to make sure that my visits to Pedantry Corner are rare, and brief.
A frequent source of irritation to me is the way that uninterested and disinterested are considered synonyms. They are not. And unlike words which mean fundamentally the same thing (often a legacy of Britain’s Norman and Saxon heritage, and liberally scattered through legal terminology, such as will and testament; aid and abet; null and void), each of these words performs a valuable service in our language.
The magistrate was uninterested means s/he’s bored.
The magistrate was disinterested means an application relating to apprehended bias is unlikely to succeed.
So while you can direct me to a dozen dictionaries and websites that now attach both meanings to disinterest, they shouldn’t be promoting the confusion. And I frequently have this discussion with lawyers, for whom language is their lifeblood, who can’t distinguish between the two.
