Latin for "All Threes are Perfect" — in writing, art, music (and countless other æsthetic and mnemonic endeavors) as per the Rule of Three. In Greek the "Hendiatris" is a triplet-based figure of speech, like the tricolon. And in politics/philosophy, a troika-triumvirate-tripartite arrangement seems to be an optimum combination of functionality, stability, and efficiency. Coincidence?

(should the Latin word be "Trinum" or "Trium"?; cf Toposes, Triples and Theories by Michael Barr and Charles Wells, There Are Three Points (2012-05-06), Big Ideas (2012-05-20), Think Better - Three Keys (2019-06-05), Three Things Tactic (2019-09-03), Creative Threes (2020-01-10), Clearly, Dearly, Nearly (2020-02-05), ...) - ^z - 2020-02-15
