Why this word is great

APRICITY — [Noun] The warmth of sunlight in winter. From the Latin aprīcitās (noun of quality from aprīcus, "warmed by the sun"), it names those rare moments when cold yields to light. Unlike "solace" (which is abstract comfort) or "radiation" (which is clinical transfer), apricity is the sun's tangible mercy—how it gilds a bare oak branch, thaws the ice on a cardinal's perch, or coaxes the first drop from a hanging icicle. This is the light that winter cannot extinguish.

noun

  1. The light or warmth of the Sun.“Apricity, the warmenes of the Sunne in Winter."”
