This is an irregular feature - both in frequency and oddness - dedicated to a word I came across that I have never previously used.
edulcorate ee-DUHL-co-rayt n. to sweeten; to make sweeter in taste; to reduce in acidity.
The word edulcorate is derived from the Latin dulcorare ("to sweeten"). The term can also be used in a figurative sense, as in cheering up a sourpuss or charming another person. William Quick at DailyPundit developed an excellent example of this sense of edulcorate:
Desperately in need of a loan, Martin used every trick he knew to cajole, flatter, and edulcorate his well-heeled but frugal Aunt Clara.
