Rob Macfarlane used to do a Word of the Day on twitter.
His word for Wednesday January 17th, 2018 was Apricity
the warmth of the sun on a winter's day
It's a complicated word for a complicated feeling.
Personally, I like the definition better than the word.
The warmth of the sun on a winter's day, sounds better than Apricity. The phrase flows better, has more feeling, is more descriptive, than just a word.
I do miss his Word of the Day. Maybe it will return soon.
