Check out this blog Wordnik
This post came about because Jan wrote about a nudnik on her blog: Through One Eye and reading her words made me think of a wordnik.
When I googled that word I came across the Wordnik blog. The word for the day was harl.

I don't think I'd have an occasion to use many of these words in my writing, but the blog makes me aware of the delights of language.
Perhaps I'll write something and use the word terpsichorean.
