Word story

English nomenclature comes straight from Latin nōmenclātūra “assignment of names to things, mentioning things by name, a list of names.” In English, the original (Latin) sense dates to the early 17th century. At the same time, nomenclature acquired the sense “a systematic assignment of names, as in botany or zoology” (as in binomial nomenclature ), and later in the same century, “the technical terms within a science.”
The noun nomenklatura “nomenclature” has existed in Russian since the early 19th century. Beginning in the Soviet Union in the 1930s, nomenklatura meant the list of names or category of people in the Soviet Union who held important positions in the bureaucracy, all of whom had to be approved by the Communist Party. English adopted nomenklatura in the late 1950s in discussing the bureaucracies of the Soviet Union and other Communist countries.
