I keep stumbling across references to the President of the United States in the Apple Dictionary (A lexicographer’s gem) :
(Definition #2) [mass noun] courtesy and considerate behaviour towards others: a show of public comity in the White House.
noun [mass noun] good manners; refinement: he has no couth, no brains and doesn’t know the meaning of the word diplomacy.
Source: Apple Dictionary, Version 2.3.0 (239.5)
Interesting to note that “couth” only is attested from the late 19th century on as a back-formation from “uncouth”. I do wonder what social forces may have been at play to usher such a word into the common vocabulary of English speakers.
Work of the translator at Google… gives the form “couth” for the French with oddball pronunciation.

Back translation leads me to Word Hippo and a definition for savoir-faire : "The ability to do or say what is appropriate for the occasion" and a long list of synonyms including "manners", "social graces", and "urbanity".

Oh and let's not forget "tactfulness".
The lexicographers may not be trolling but I am.
And so for day 2773
