A few months ago I started a thread about over-used words. This time, I wanted to ask if there were any words that you frequently see in novels but almost never hear people using them in conversation. For me, I began noticing that almost every book I read had the word - "rivulet" in it. I don't think I've ever heard someone say that in normal conversation. Now every time I run across that word it jumps out at me. I even made sure I could use rivulet in my WIP just for the hell of it.
