"Vituperative" is a word in ENGLISH

Yesterday morning, I awoke to a brilliant rainbow. At first, I marveled at the sky’s pink hues, and I thought how soothing it was. I haven’t had that feeling in a long time, that feeling of being at peace with myself or my life. I got out of bed to stand to pull the obligatory curtain further, the color peeking through the leaves of the oaks outside my window. Where I had been seeing grey for quite some time shone now pink. The color is hard to describe accurately. It was pink; but it bordered on a light red. It told me to come look at it.
