Interestingly, while writing tonight on my work in progress, I went to my trusty thesaurus in search of a nice synonym for the word "nonchalance" because it just didn't seem to fit my character. What I stumbled onto was this word:
Yeah, I hadn't heard of this word either. Turns out, and it may seem obvious from the way the word is spelled, that this word is derived from French word "soucier" which means "to trouble or disturb" which means that the word insouciance basically means "not toubled by" ie...nonchalant
Now why nonchalance is the word most people are familiar with and not this word is a mystery to me and one I'm not willing to spend more time on than I have just now in researching this new word in the first place. Even so, I'm at least putting this note in my blog since it's always nice to add a new word to my vocabulary and to the possibilities of what I can do on the page by using it.
(thought I'm totally not using it in my novel...no way, it't nothing my character would dream of using in a sentence :) )
