Not sure how I have been receiving “word of the day” emails. I don’t remember signing up for anything but perhaps a higher authority has notice my lack of classy verbiage flowing freely from my brain down through to my typing fingertips. Try this one on. I just received my email: pervicacity. The quality or state of being pervicacious. Obstinacy; stubbornness; wilfulness. Let me use it in a sentence. I believe the other person living in my home is the perfect example of pervicacity.
