While reading a newspaper I saw the word nonchalance, looked up in dictionary, and read it is a negative word meaning "indifference; carelessness; coolness." It looks like the opposite of chalance, but I was surprised to see there is no word as chalance. I am wondering if:
- Isn't nonchalance made by adding non to chalance similar to nonsense?
- What is the opposite of nonchalance? Can I write nonnonchalance just for the fun of it?
