Apricity is a word that the Pothi.com team stumbled upon on Twitter. It’s a rare word, having appeared in 1623 when Henry Cockeram recorded or invented it it for his dictionary. The word never really took off.
Here are some instances of this word used in literature:
Apricity (n.) the warmth of the sun in winter.
A strange a lovely word. The OED does not give any citation for its use except for Henry Cockeram’s 1623 “English Dictionarie”. Not to be confused with “apricate” (to bask in the sun), although both come from the Latin “apricus”, meaning exposed to the sun.”

“Apricity. That’s what it’s called. A word Reuben taught me: the warmth of the sun in winter.”
