This word is interesting to me because the root word "fact" means truth and reality as opposed to this meaning- artificial and contrived.
I wonder if when I use this word, people will think I don't know what I'm talking about. Then, my purpose in incorporating these words into my vocabulary to sound more intelligent will be futile.
Maybe I shouldn't use it...

Do any of you used this word? Would you?
