Etymology

Origin of nomenclature

First recorded in 1600–10, nomenclature is from the Latin word nōmenclātūra “a calling by name, list of names.” See nomenclator, -ure

Explanation

When adjusting to a new job, you may have trouble understanding the nomenclature, or system of naming things, in the workplace. Just remember: they’re "guests," not "customers," and they push a "purchase buggy," not a "shopping cart." The nomen- in nomenclature comes from the Latin word for name. Nomenclature is a system for giving names to things within a particular profession or field. For instance, you may have heard of binomial nomenclature in biology class. It applies to the way of referring to living things by two names, like calling humans Homo sapiens. Biologists all follow the same nomenclature so that they are easily understood by each other.
