Language is always fun to use to better effect, whether it is to make your point or break your adversary’s point. All natural languages are rich and contain a number of regional, rare or made-up words. French has a number of them and so does English.
Rare, nonce, or simply made-up words show up in comedy, literature, and even programming. As I am not a native English speaker (which I am sure you gathered by now by reading this blog) I do often read books about English to better my grasp of the anglo-saxon language. Not all of them too serious.
