Today’s word of the day in my vocabulary building day calendar?
But I think it’s pronounced batmen, or more accurately, like watchman. It means: “A British military officer’s orderly.”
One time the word of the day was “tricksy,” and that’s when I learned that Tolkien didn’t invent that word.
Also: Spinal Column. That was a word of the day one Saturday.
Didn’t learn much that weekend.
