Here are two examples of irony.
1. When I told my C-grade classmate that I had received an A, his ironic reply was, "How nice." (He didn't mean it was nice.)
2. "This is a magnificent view," Joan's mother said ironically, as she stared out the window at the neighbor's brick wall.
Here's a typical use of the word as I hear it today: "How ironic that I can't go to Bible study tomorrow night," the seminary student said, "because I have to prepare for a test on the New Testament." This statement passes for what some call irony because it's unusual. There's no intended opposite meaning.
Words are my tools, and I try to use words properly,
even if others don't.
