12. Apricity
Apricity was a word denoting the feeling of the warmth of the sun, specifically on a cold winters day something that you've all felt with great relief at one point or another. Coming from the Latin apricus meaning warmed by the sun, the word itself sounds charmingly like the image of sunlight twinkling on fresh snow. Although denoting a fairly specific phenomenon, its hardly less necessary than three different words for window-separating elements; however, this word is largely obsolete now. Heres hoping you can bring it back in vogue in time for the upcoming winter, because it really is quite delightful.
