Notes: A word I could have known (had I studied the language from which it comes), but since I didn’t, I don’t!
The word zaibatsu is “a powerful and industrial conglomerate of Japan”
The word is Japanese; it is a compound word of zai (wealth or money) and batsu (clique or clan). It referred to large enterprises that sprang up in Japan after the Meiji Restoration of 1868. They expanded rapidly during World War I. Each zaibatsu was typically organized around a single family and controlled interests in multiple areas. During the Allied occupation of Japan after World War II, zaibatsus were dissolved, but the term has survived.
This world entered English after World War II (the mid- to late 1940s)
